Structure
optibelt RED POWER 3 wedge belts:
The tension cord consists of a special polyester cord. Due to
the special processing of the tension cord the optibelt RED
POWER 3 wedge belt is very low-stretch and maintenance-
free, so that re-tensioning is not necessary.
The transverse bre mixture on top of and under the tension
cord guarantees a high dynamic load of the belt and
ensures great exibility. The cover fabric is highly exible
and abrasion-proof.
Properties
The optibelt RED POWER 3 is maintenance-free due to the
high quality components and the special production method.
The production processes are continuously monitored using
state-of-the-art static and dynamic testing devices. The
optibelt RED POWER 3 is suitable for the application in
drives with idler pulleys due to its special construction.
The optibelt RED POWER 3 has the following properties:
• Maintenance-free
• Powerful
• Cost-effective
• S=C Plus usable in sets
• Environmentally friendly
• Electrically conductive according to ISO 1813
• Oil-resistant
• Heat-resistant
• Dust-protected as standard
On request with acceptance test certicate according to
EN1020 “3.1.B“.
V-belt tensioning
For the initial installation of optibelt RED POWER 3 V-belts,
the same methods are used as for standard Optibelt V-belts.
The tension values are to be calculated on the same basis or
to be taken from the table on page 147. Once correctly
tensioned optibelt RED POWER 3 V-belts need no
re-tensioning.
Application areas
optibelt RED POWER 3 wedge belts were especially
developed for mechanical engineering. The application
areas include compressors, pumps, presses, fans and other
heavy duty drives.
Standardisation/Dimensions
optibelt RED POWER 3 wedge belts in the proles SPZ, SPA,
SPB, SPC, 3V/9N, 5V/15N and 8V/25N are standardised
according to DIN 7753 Part 1, ISO 4184 and ARPM/MPTA.

Structure/Properties
optibelt BLUE POWER wedge belts:
The aramid tension cord has extremely low stretch compared
to common materials such as polyester. The breaking
strength is almost twice as high with the same cord diam-
eter. Nevertheless, the bre is extremely exible.
The high quality specially prepared aramid tension cord is
embedded in a rubber compound. It is supported by the top
and bottom structures. These consist of a polychloroprene
rubber compound with tranverse bres.
The abrasion-proof cover fabric is coated with a special
rubber compound and covers the whole belt. The V-belt is
electrically conductive according to ISO 1813
Application areas
optibelt BLUE POWER belts are mainly used when
• highest power transmission levels are required
• there are limited design dimensions
• there is only little installation and tensioning space
• high temperature inuences occur
This way. a much better performance is guaranteed e. g.
with the same number of belts. Even the operation of once
critical drives is now largely free of risk. Higher load limits
are now safety zones. Thus optibelt BLUE POWER belts are
mainly implemented in heavily loaded drives:
• in critical drives in mechanical engineering
• in special machines
• in agricultural machinery
Application
Attention: When retro-tting existing drives please let
Optibelt check the tension. As part of this description not all
criteria can be dealt with. Please consult our Application
Engineering Department.

Structure
optibelt SK high performance wedge belts consist of:
The polyester tension cord is standard for all proles and
cross sections. with cord constructions matching the require-
ments of each prole. The cord is specially impregnated and
then embedded in a special rubber compound homogenous-
ly bonding with the top layer and the core.
Due to special processing. the optibelt SK wedge belt is
extremely low-stretch. Thus we were able to reduce our
recommendation values for minimum axial distance signi-
cantly – even dropping below the DIN/ISO requirements.
The fabric cover is treated with a wear-resistant rubber
compound. This makes the belt resistant to oil, hot and cold
temperatures and to the effects of dust.
Properties
The use of the best materials and the most advanced
production methods result in this high performance drive
element, the optibelt SK wedge belt. The production pro-
cesses are continuously monitored using state-of-the-art static
and dynamic testing devices.
optibelt SK high power wedge belts exceed classic V-belts
according to DIN 2215 thanks to the following characteris-
tics:
• Substantially lower width compared to classic V-belt
drives that have the same power rating (height to width
ratio of approximately 1 : 1.2). Due to the available space
gained by this. the costs for a complete drive with
optibeltSK high performance wedge belts are lower than
a design with DIN 2215 V-belts.
• Bigger friction surface lowers the centrifugal force and
permits belt speeds of up to 42 m/sec.
• Much more elastic. therefore bigger ex rate allowed.
• Little deformation of the belt cross-section when running in
grooves, therefore balanced pressure on the belt edges.
These characteristics allow for a signicantly better perform-
ance than V-belts DIN 2212 with approximately the same
top widths. Therefore, we recommend equipping all new
drives with optibelt SK wedge belts.
Application areas
optibelt SK wedge belts in the proles SPZ, SPA, SPB and
SPC were specially developed for all industrial applications
from lightly loaded drives. such as those for pumps, up to
heavily loaded mills and even stone crusher drives.
Standardisation/Dimensions
optibelt SK wedge belts SPZ, SPA, SPB and SPC comply
with the standards of DIN 7753 and ISO 4184.
The ISO standards specify the datum width as a basis for
the standardisation of V-belts and grooves.
The staggering of the datum lengths is implemented accord-
ing to DIN 7753 Part 1 corresponding to the standard
number sequence R 40. In exceptional cases also corre-
sponding to standard number sequence R 20.
For many years. our product range has comprised serial
production datum lengths of standard number sequence
R40 and beyond.
Note: Electrically conductive according to ISO 1813.

Structure/Properties
optibelt SK high performance wedge belts according to
ARPM/MPTA have the same structure and properties as
wedge belts according to DIN 7753 Part 1.
Standardisation/Dimensions
The three wedge belt proles standardised in the USA are
3V/9N, 5V/15N and 8V/25N. The cross section dimen-
sions of these belts and the according length only partially
conform to the proles and lengths of the wedge belts
DIN7753 Part 1.
The prole 3V/9N roughly corresponds to SPZ; and
5V/15N to prole SPB. There is no comparable DIN/ISO
wedge belt prole for 8V/25N. It is possible to use belts in
prole 3V/9N and 5V/15N in SPZ-Z/10 or SPB-B/17
pulleys. respectively; but the use of SPZ or SPB belts in
ARPM/MPTA standard pulleys is not generally recommend-
ed. The top width of the American pulley grooves is smaller
than that of the corresponding DIN/ ISO pulleys. This can
cause wear on the upper edges of SPZ and SPB belts and
can lead to premature failure.
Due to its cross section, the optibelt SK wedge belt in SPB
prole is also suitable for 5V/15N pulleys.
Note: Electrically conductive according to ISO 1813.
The belt length designation refers to the effective outside
length.
Example:
Application examples
The use of optibelt SK wedge belt drives in proles 3V/9N
and 5V/15N is recommended for machines exported to
countries such as the USA and Canada where these belt
proles are standardised and predominantly used.
Prole 8V/25N is primarily employed in very heavy duty
drives such as mills or stone crushers. As these wedge belts
transmit very high levels of power, they can sometimes form
a more compact drive than the SPC prole.
For this reason. the 8V/25N prole has continued to be
used in Europe for such applications. A further advantage is
the fact that single wedge belts can be replaced by kraft-
bands, without changing the pulley geometry, in case
unexpected belt vibration problems develop.
Drive calculation
Drive calculations follow the procedures described in this
manual. The power value of the SPZ applies for drives with
the 3V/9N prole. The value of the SPB prole applies for
5V/15N. The datum diameters of the SPZ and SPB wedge
belts have to be the same as the external diameters of the
3V/9N and 5V/15N. Slight mathematical differences in the
rotational frequency and transmission have no practical
inuence. Slight differences in the theoretical drive speed
and the speed ratio are not signicant in practice.

Structure/Properties
optibelt VB classic V-belts are manufactured using the same
production processes as those for optibelt SK high perfor-
mance wedge belts.
The components used are perfectly suited to the power
ratings P
N
. These values are far above those given by
DIN2218. Thus the operational safety in existing drives is
increased and overloading is avoided.
• optibelt VB classic V-belts have a height-width ratio of
1:1.6.
• The maximum belt speed v
max
= 30 m/s should not be
exceeded.
• The allowed exibility rate is far below that of wedge
belts. It is f
B max
= 80 s
-1
.
Application areas
optibelt VB classic V-belts are mainly employed as
replacement parts for industrial drives. For new drives, the
use of high performance wedge belts is almost always
recommended due to reasons of space and cost. However,
special drives such as V-at drives can often only be
operated with classic V-belts. In special constructions,
optibelt VB classic V-belts tackle difcult drives in the
gardening sector and in agricultural machinery.
PRODUCT DESCRIPTION
optibelt VB CLASSIC V-BELTS
DIN 2215 / ISO 4184
For these applications special belt constructions and calcula-
tion methods are required which are not included in this
manual. In these cases we ask you to give us the according
drive data.
Standardisation/Dimensions
optibelt VB classic V-belts in the proles Y/6, Z/10, A/13,
B/17, C/22, D/32 and E/40 are standardised according
to DIN 2215 and ISO 4184.
Further, non-standardised ISO proles 5, 8, 20 and 25 are
available. These proles should however not be used due to
reasons of exchangeability and rationalisation.
The ISO standard 4184 species the datum length
for measuring the belt length. The former belt
designation of the inside length L
i
is replaced by
the datum length L
d
. For the conversion factors
from pitch to inside length, please see page 167.
Note: Electrically conductive according to ISO 1813.

Belt tension / Static shaft load
Belt tension and static shaft load are calculated in the same
way as for wrapped belts. When dealing with the same
geometric ratios, the shaft load does not exceed that of
wrapped belts although the quantity of the belts is often less.
Therefore, only the individual V-belt requires higher tension
than wrapped belts.
The precise edges of the optibelt SUPER X-POWER M=S
V-belt ensure uniform seating in the pulley grooves, resulting
in smoother running.
Drive calculation
Drive design using optibelt SUPER X-POWER M=S belts
should be carried out according to the examples given on
pages 83 to 85. The higher power ratings given in the
relevant tables, apply. These are based on a theoretical
laboratory running time of 25.000 hours.
Standardisation/Dimensions
The cross sections and dimensions of optibelt SUPER
X-POWER M=S V-belts are in accordance with DIN 7753
Part 1, DIN 2215, ISO 4184 and ARPM/MPTA.
The basis for the length measurement is the datum length (L

)
to DIN/ISO.

The advantages of optibelt SUPER TX M=S V-belts can best
be seen when dealing with
• extremely small pulley diameters
• high rotational speeds
• extremely high power requirements
• higher ambient temperatures
In these cases the use of wrapped V-belts is uneconomic and
not recommended.
optibelt SUPER TX M=S V-belts in proles ZX/X10, AX/X13,
BX/X17 and CX/X22 offer the best technical and economic
solutions under these conditions due to their high quality
perfectly harmonised materials.
Structure/Properties
optibelt SUPER TX M=S consist of:
The belt base consists of a polychloroprene rubber com-
pound with traverse bres which support the tension cord.
This results in
• signicant exing rate
• extreme traverse stability
• signicantly improved wear resistance and
slip resistance
• electrically conductive according to DIN 1813
• low stretch
The specially prepared tension cord is embedded in a
special compound. Even with high dynamic loads a perfect
adhesion between all components is assured.
The fabric layers of the upper structure support the tension
cord. The bre-reinforced substructure combined with the
Optibelt tension cord and the moulded cogs allows for a
higher dynamic power transmission.
The moulded cogs decrease the exing resistance, resulting
in an excellent exing rate. Thus, much smaller pulleys can
be used compared to common wrapped V-belts.

PRODUCT DESCRIPTION
optibelt VARIO POWER VARIABLE SPEED BELTS
RAW EDGE, COGGED / DOUBLE-SIDED –
DIN 7719 / ISO 1604
optibelt VARIO POWER variable speed belts –
raw edge, cogged
Increasing demands on variable speed belts due to the
continuous increase of power transmission levels initiated
the development of the raw edge, cogged variable speed
belts.
The base compound consists of a polychloroprene rubber
compound with traverse bres. The high quality and
extremely low-stretch polyester or aramid tension cord is
embedded in a rubber compound. It is effectively supported
by an upper and substructure. The special characteristics of
the raw edge. cogged variable speed belt are:
• high power transmission
• excellent exibility in running direction
• high traverse stability
• exceptionally smooth running
• wear and slip resistance
• long operational life
• electrically conductive according to ISO 1813

Gearboxes: variable diameter pulley sets
Agricultural machinery: thresher drum drives
Textile machinery: winding machinery
Machine tools: lathes
Automotive technology: snowmobile drives
optibelt VARIO POWER variable speed belts –
rawedge, Double-sided
Further increases in demand on the performance of drive
elements and the trend towards designing ever smaller,
space saving drive units, led to the development of the
Double-sided, raw edge optibelt VARIO POWER variable
speed belt.
Double-sided Optibelt variable speed belts allow for the
smallest pulley diameters, even below standard recommen-
dations. The Double-sided design improves heat emission,
thereby signicantly reducing the belt running temperature.
The production methods and the structure of the belt have
been derived from the raw edge optibelt VARIO POWER
variable speed belt. Depending upon the application and
application range, this belt can also be equipped with layers
of special cross-cord material in the base compound. The
belt is Double-sided, with the depth and spacing of the cogs
matching with the specic belt prole. The polyester or ara-
mid tension cord ensures ideal power transmission, in-
creased service life, and extremely low-stretch characteristics.
The features of the optibelt VARIO POWER variable speed
belt can be summarised as follows:
• extremely high acceptance of axial loads
• high exibility and exing rate
• better heat emission
• use with small pulley diameters
• high running smoothness with high belt speeds
• long operational life
• electrically conductive according to ISO 1813

Structure
A cross section of the optibelt DK double-sided V-belt reveals
a hexagon made up of two congruent trapeziums. The
neutral axis containing the tension cord is exactly half way
up the belt prole.
optibelt DK double-sided V-belts consist of:
Properties/Application areas
The tension cord positioned at the centre of the belt gives
the optibelt DK double-sided V-belts extreme exibility and
low-stretch properties. Thus, the belt is particularly suitable
for exing in different directions in the same plane. optibelt
DK double-sided V-belts are used when several pulleys are
arranged in one plane and the direction of one or more of
the driven pulleys has to be changed without crossing the
belts. Due to the position of the tension cord in the neutral
axis and the special shape of the double-sided V-belt, the
tension cord is not subjected to any force other than tension
unlike standard V-belts bent around an outside idler. The
optibelt DK double-sided V-belt comes up to typical serpen-
tine arrangements. Special constructions with different top
surfaces are possible. Mainly, double-sided V-belts are used
in agricultural machinery but also in mechanical engineer-
ing.
Standardisation
The cross dimensions of the optibelt DK double-sided V-belts
comply with DIN 7722 and ISO 5289.

STANDARD PROPERTIES
S=C Plus “SetConstant”
This stands for wrapped V-belts that can be used in a set
without measuring.
The tight set tolerances are achieved by the Optibelt
rotational vulcanisation process ORV. In this process, which
is optimal for wrapped V-belts, the shaping and vulcanisa-
tion takes place in the curvature. This also results in a length
stabilisation of the tension cords. During the nal, separate
length stabilisation, the tight S=C Plus tolerances are ensured.
And here are the advantages:
saves energy, efciency of up to 97 %
consistent power transmission
incorporates the world famous S=C Plus tolerances:
always at nominal length
extremely low-stretch
longer service life
set code numbers are not required
reduces vibrations with resultant smooth running
requires only minimal adjustment space
reduces self-heating, thus ageing resistant
longer maintenance intervals
simple storage
signicant cost reductions
Example of S=C Plus length tolerances in a high perfor-
mance wedge belt with 5000 mm datum length:
The dimension (A) is the tolerance allowed according to DIN
of an individual V-belt with a length of 5000 mm. If you
want to install sets for multi-groove drives, the individual
elements in a set should not deviate more than 6 mm (B).
optibelt S=C Plus V-belts meet considerably closer tolerances
than those specied by the industry standard for sets.
optibelt S=C Plus V-belts are always in the nominal length.
All Optibelt V-belts are manufactured using care-
fully
selected basic materials and continuously
updated technical procedures.
Regular routine checks during production, exten-
sive laboratory tests and careful testing of the raw
materials used guar
antee the consistently high
level of quality that can be expected from every
Optibelt drive element. Reliability and service life
are considered the most important criteria.
Oil resistance
The limited oil resistance prevents the damaging effects of
mineral oils and greases, as long as these substances are not
in permanent contact with the timing belt and/or are not
present in large quantities. Animal and vegetable fats aswell
as water-soluble cooling and cutting oils result in a reduction
of the service life. For higher concentrations, we recommend
the use of our optibelt
RED POWER 3 V-belts or special
version
optibelt
SUPER TX.
Heat resistance
Standard V-belts allow ambient temperatures of up to
+70 °C. Temperatures exceeding this range lead to pre-
mature ageing and hardening of V-belts. In such cases,
we recommend the use of our special constructions
optibelt
RED POWER 3 or optibelt SUPER XE-POWER PRO M=S
or
optibelt SUPER TX M=S. For details see page 23.
Dust protection
Dust enormously reduces the service life of V-belts. Wear-
resistant fabric covers make Optibelt V-belts resistant to dust.
This is demonstrated by their continuous application in
cement factories, mills, in the stone processing industries, and
in the mining industry.
M=S “Matched Sets”
optibelt SUPER XE-POWER PRO M=S
and optibelt SUPER TX
M=S are raw edge, cogged V-belts that can be
used in sets
without measuring.
DUE TO SPECIAL PRODUCTION PRO-
CESSES the narrowest tolerances can be achieved so that
V-belts of a given nominal length can be combined without
further measurement. The precise edging of the belt results
in smooth running. The even power transmission of all belts
ensures ahigh efciency and saves energy. Set code
numbers are not necessary, there is no set bundling. As a
consequence, storage and costs can be reduced.

SPECIAL CONSTRUCTIONS
Extra heat-resistant V-belts
The service life of standard Optibelt V-belts can be mas-
sively reduced due to the effects of temperature.
In case of ambient temperatures that constantly vary
between + 70 °C and + 90 °C we recommend optibelt
RED POWER 3, optibelt SUPER XE-POWER PRO M=S or
optibelt SUPER TX M=S belts. Special rubber compounds
largely prevent premature ageing and brittleness. In border-
line cases, trials are
recommended, as individual drive
parameters such as belt speed and pulley diameter may
inuence the operational life
.
The diagram below illustrates the great impact of ambient
temperature on the operational life of belts. It also presents
the optimised operational life of special constructions in
high temperature ranges compared to standard constructions.
However, you cannot expect the same service life as under
normal conditions.
Smooth-running selected V-belts
Drives that require smooth running – that is variations of
shaft centre distances – such as lathes and grinders, and are
supposed to guarantee vibration free operation, should be
equipped with Optibelt V-belts with “smooth-running selected”.
Fluctuations in the shaft centre distance are electronically
measured on testing machines. The measurements comply
with the Optibelt standards or the conditions agreed upon
with our customers.
Mining industry
optibelt SK wedge belts and optibelt VB classic V-belts can
be used in underground mining as well as in areas above
ground that are exposed to explosion and re risks.
For these areas, different national and international testing
specications and standards apply.
Optibelt “Mining Belts“ comply with all requirements of
“DIN 22100-7”.
Applications with other special constructions
For special applications e.g. in general mechanical engi-
neering, agricultural machinery and horticulture, further
special constructions are also available in intermediate sizes
for
• special drives with tension, back bend and guide idlers
• clutching drives
• shock loads
• extreme operating conditions
These Optibelt V-belts in special constructions have different
tension cord types and structures with a variety of rubber
compounds, different fabric qualities and a differing number
of fabric covers and top surfaces.
All special constructions and intermediate lengths must be
ordered in sets or in multiples thereof.
It is not possible to go into the entire range of criteria in this
manual. For further information please contact our Applica-
tions Engineering Department.

PRODUCT DESCRIPTION
optibelt KS V-GROOVED PULLEYS, TYPES
We reserve the right to technical modications.
Balancing
V-grooved pulleys are statically balanced in accordance
with the guidelines in VDI 2060, as standard:
Quality level G 16; for dia. d
d
≤ 400 mm at n =1500 rpm;
for dia. d
d
> 400 mm at v = 30 m/s.
The pulleys are balanced without keys on smooth balancing
spindles. Machines whose runners are balanced with a
keyway in the shaft end should be ordered as follows:
“Balanced with pilot bore and empty keyway on smooth
balancing spindles without key“.
Balancing in one plane to quality level G 6.3 on request.
We recommend balancing in two planes according to
quality level G 6.3, or ner when v > 30 m/s or the ratio of
datum diameter to face width d
d
: b
2
is < 4 at v > 20 m/s.
In such cases. the operational speed of the pulley must be
given.

• Balancing in two planes (dynamically), quality level
Q6.3 becomes necessary if:
1. v > 30 m/s or
2. the ratio of datum diameter to pulley face width
d
d
: b
2
< 4 at v > 20 m/s.
Note: The timely replacement of pulleys damaged by
corrosion or erosion prevents premature failure of the belts.
Furthermore, it is important to prevent the belt basis from
direct contact with the groove basis as this can quickly lead
to damage and premature failure (exception: special drives
such as V-at drives).
Deep grooved pulleys
Deep grooved pulleys are employed for special drive
situations such as
• The use of guide idlers.
• Twist drives or.
• Drives subject to severe vibration.
The increased groove top width “b
1
“ and depth “t“ of deep
grooved pulleys improves the running characteristics of the
belt, particularly when entering the groove. Turning over
and running out of the belt are prevented.
Deep grooved pulleys are not suitable for the use
with kraftbands.

PRODUCT DESCRIPTION
optibelt KS V-GROOVED PULLEYS,
STANDARDS – DESIGN CRITERIA – TYPES
An essential component in V-belt drive systems is the V-belt
pulley, or in short V-pulley. They are primarily manufactured
from cast iron EN-GJL-200-DIN EN 1561 and are available
with a pilot hole, pre-fabricated hole or with a clamping
bush system. The DIN standard as well as the most impor-
tant national pulley standards of all industrial nations are
based upon the ISO 4183 standard “Grooved Pulleys for
Classic V-Belts and Wedge Belts”.
V-belt pulleys with grooves for wedge belts according to
DIN 7753 Part 1 are also suitable for classic V-belts with
the same datum width b
d
according to DIN 2215. These are
known as dual duty pulleys.
Example
When selecting a pulley. the following criteria should be
taken into account:
• Use standard pulley diameters.
If design considerations make this impossible, a standard
diameter should. as a minimum requirement, be selected
for the largest pulley in the drive.
• Do not select a pulley smaller than the recommended size
to ensure a longer operational life and overall drive
efciency.
• If manufacturing your own pulleys, the overall shape and
processing must conform to the relevant standards.
• Grooved pulleys are generally balanced in one plane
(statically) to quality level Q 16 as in VDI 2060.

For drives with several grooves the total of all deviations from the nominal value e for all groove distances of a pulley ± 0.8 mm must not be exceeded.
Forfurther details see ARPM/MPTA.
Note
The allowed variations of V-grooved pulleys according to ARPM/MPTA deviate only slightly from the values contained in ISO 5290 “Grooved pulleys
for joint narrow V-belts (Kraftbands)”. Therefore, optibelt KB kraftbands can be used in V-grooved pulleys manufactured according to both standards.
These V-grooved pulleys are also suitable for optibelt SUPER X-POWER M=S V-belts.

OVERVIEW – GEOMETRY DATA
optibelt KS V-GROOVED PULLEYS FOR KRAFTBANDS
For further details please see standard ISO 5290.
1) Tolerance for the centre distance “e” of two adjacent grooves.
2) The sum of all deviations from the nominal dimension “e” for all groove distances of a pulley must not exceed the given tolerance.
The international standard ISO 5290 species pulley groove
dimensions for belt proles 3V/9J, 5V/15J, 8V/25J.
Thegroove top width “b
1
” is used as the basic reference
dimension for standardisation of the grooves and joint
V-belts. The pulley groove and joint V-belts are considered
as a single unit in the standard ISO 5290.
The values δ h
1
and δ h
2
were chosen to ensure that
1. the top cover of the joint belt has no contact with the
outside pulley diameter, in order to prevent the separation
of the top cover.
2.
the ribs are nevertheless still deep enough inside the
pulley in order to ensure an optimum power transmission
.

DRIVE CALCULATION
OPTIBELT NOMINAL POWER RATING P
N
–
ARC OF CONTACT CORRECTION FACTOR C
1
The Optibelt nominal power ratings P
N
in tables 32 to 68
are based upon an internationally accepted basic formula
and a theoretical belt life of 25.000 hours under ideal
conditions. This formula contains material constants that take
into account the quality of the raw materials used and make
allowances for production methods. Due to the special quali-
ties of Optibelt V-belts, other material constants than those
given in DIN have been taken into account. As a result, the
nominal Optibelt power ratings P
N
signicantly exceed the
ratings given, for wedge belts according to DIN 7753
Part2 and for classic V-belts according to DIN 2218, for
the same theoretical belt life. The nominal power ratings P
N
are based on the smallest loaded pulley in the drive system.
The belt power rating value P
N
is calculated taking into
account
• the datum diameter of the smaller pulley d
dk
• the speed of the smaller pulley n
k
• the drive ratio i
• an assumed arc of contact at the smaller pulley of
β=180°
• a reference belt length for the specic belt prole
In order to account for the actual drive data, based on the
arc of contact and the belt lengths employed, correction
factors for the arc of contact c
1
and length c
3
have been
introduced. If required. drive calculations can be provided
for any theoretical belt life.
Intermediate values for nominal power rating, arc of contact
and length correction factors can be found via linear
interpolation.
The factor c
1
corrects the power rating P
N
, when the arc of
contact is smaller than 180°, as the P
N
value is calculated
on the arc of contact β = 180° on the smaller pulley.

DRIVE CALCULATION
LOAD FACTOR c
2
The service factor c
2
takes account of the daily operating
time and of the type of driver and driven machine. It applies
exclusively to two-pulley drives. Other arrangements such as
drives with tension and guide idlers have not been taken into
consideration. Pages 136-137 provide the relevant basic
design guidelines for drives with more than two pulleys.
Adverse operating conditions (e.g. aggressive dust, particu-
larly high ambient temperatures or the effects of various
substances) have not been taken into account. As it is
practically impossible to cover every conceivable combina-
tion of driver/driven machine/operating conditions in a
summary that complies with the relevant standards, the
service factors are approximate values.
In special cases. e.g. increased starting torque (direct on-line
starting of fans), in drives with frequent starts and stops, in
systems subject to exceptional shock loads, or when signi-
cant masses are to be accelerated or braked, the service
factor must be increased.
Empirical value:
With a starting torque > 1.8 this gure is to be divided by
1.5 in order to calculate the minimum load factor c
2
.
Example: Starting torque MA = 3.0; c
2
selected 2.0.
Please consult our Applications Engineering Department for
the solution of special problems.

Examples for drive machines
AC motors and three-phase induction
machines with a normal starting torque
(up to 1.8 times nominal torque), e. g.
synchronous motors and single-phase
motors with a starting-aid phase, three-
phase squirrel cage motors with direct
start, star-delta connection or slip ring
starters; direct-current shunt-wound mo-
tors, combustion engines and turbines

AC motors and three-phase induction
machines with high starting torque
(over 1.8 times nominal torque), e. g.
single-phase motors with high starting
torque; direct-current series-wound mo-
tors with series connection and com-
pound; combustion engines and tur-
bines n < 600 rpm

DRIVE CALCULATION
LENGTH FACTOR c
3
FOR OPTIBELT WEDGE BELTS
AND KRAFTBANDS
The length factor c
3
takes into account the ex rate of the
belt based on the reference length for the particular belt
prole.
This results in the following relationships:
belt length > reference length c
3
> 1.0
belt length = reference length c
3
= 1.0
belt length < reference length c
3
< 1.0

DRIVE CALCULATION
GUIDELINES FOR SELECTING THE SUITABLE PROFILES
FOR V-BELTS AND KRAFTBANDS
By using the following diagrams, the most suitable belt
proles as far as efciency and size are concerned, can be
selected for a specic application. The most efcient power
transmission and economy is achieved by selecting as large
a pulley diameter as possible for the prole in question. The
limits to be observed are the maximum allowed circumferen-
tial speed, namely for
high performance wedge belts v
max
= 55 m/s*;
for classic V-belts v
max
= 30 m/s.
If the circumferential speed is outside this recommendation,
please contact our Application Engineering Department.
Experience has shown that minimum pulley diameters should
be avoided. These drives require a larger number of belts
with wider pulleys and are therefore more expensive.
In borderline cases we recommend using the next smaller
prole belt for the same pulley diameter, as the smaller
prole will often save both cost and space. A further
recommended solution is the use of the raw edge
optibeltSUPER X-POWER M=S V-belts.
Furthermore. we recommend evaluating if the intersection
point in the selection diagram is in the limit values of two
proles.
Comparing space requirement and costs, the high
performance wedge belt is usually far superior to classic
V-belts in almost all industrial drives. For this reason.
newconstructions use high performance wedge belts almost
exclusively. Only in special cases, for replacement parts, or
for V-at drives or special cases where the application of
classic V-belts is obligatory.

V-FLAT DRIVES
The V-at drive comprises one grooved pulley and one at
pulley. This type of gear can. under certain conditions, be
used for drives with intermittent loading or with large
moments of inertia. As ywheels or at pulleys are often
already present, the costs of the drive can be reduced.
When changing over a at belt drive to a V-at drive, it will
usually be economical to continue to use the at pulley.

• For classic V-belts, the length is calculated using the
datum length L
d
, and for kraftbands using the outside
length L
a
. Therefore, the correction factor D
z
must be
added to the outside diameter of the at pulley in order
toapproximate the theoretical design diameter.

Calculating V-at drives
The calculation of V-at drives is based on the same meth-
odas presented on pages 83 to 85. In order to ensure
reliability and efciency, the V-at belt drive must meet the
following requirements:
• The small pulley must always be V-grooved.
• When using single belts, only classic V-belts in proles
Z/10, A/13, B/17, C/22, D/32, E/40 must be used.
• Wedge belts must never be used as their narrow base
and larger relative height tends to make them turn and
twist.
• All optibelt KB kraftbands – both with wedge belts and
classic V-belts – are particularly suitable for this type of
drive due to their single belt characteristic. Turning over
even under extreme shock load conditions is prevented.
• A V-at drive is particularly economic when
The optimum drive dimensioning is achieved when
kf=0.85. If the factor kf is outside the recommended
range, it is more economical to design a standard V-belt
drive.
• The following recommendations result from these
requirements:
• When calculating the number of belts and the belt
tension, it should be noted that a special arc of contact
factor c
1
must be used as shown in the following table.

• The at pulley should be shaped cylindrically. With
existing at pulleys that are re-used for the V-at belt
drive, the height of the crown should be checked.
The following conditions must be met:

PRODUCT DESCRIPTION
optibelt OPTIMAX HF
ENDLESS HIGH PERFORMANCE FLAT BELTS
Structure
The raw material of the optibelt OPTIMAX HF high perfor-
mance at belt is polyester yarn. This will be woven to
endless sleeves and then covered with a high-quality rubber
compound on both sides.
optibelt OPTIMAX HF high performance at belts are
produced in two different types that differ in thickness and
strength.
Type HF 150 is intended for general use, whereas type 075
is only intended for special drives.
Characteristics
optibelt OPTIMAX HF are particularly distinguished by the
following features:
• High exibility
• Very small pulley diameters (HF 075 from 6 mm)
• High belt speeds
• High efciency
• Low noise development and low vibration
• Low maintenance requirement
• Good chemical and ozone resistance
• High friction values (0.5 μ)
A special advantage of this drive element is the low thick-
ness. As a result. very small pulley diameters are possible,
which almost always leads to a considerable cost reduction.
Due to the use of high-quality synthetic materials, a very
high strength is reached despite the low belt thickness.
In addition, the raw materials used guarantee a temperature
resistance of –30 °C to +110 °C. With optibelt OPTIMAX HF
high performance at belts, belt speeds of up to 50 m/s are
easily possible. No noise and vibrations occur.
Due to its low elongation, this belt can be used even for
drives with xed centre distance for low power transmission
systems.
Without engendering the risk of a reduced lifetime, idlers
can be used in a at belt drive. This can be done for
tensioning or power reduction.
The high-quality neoprene rubber compound makes optibelt
OPTIMAX HF high performance at belts conditionally
resistant to oil, fat, solvent and moisture.
optibelt OPTIMAX HF are electrically conductive; an
ISO1813 certicate can be issued on request.
Application areas
For power transmission, optibelt OPTIMAXHF belts are
particularly used in drives with a medium torque or high
speeds. Examples of this include: Tool, wood processing.
textile, printing, dyeing as well as agricultural machines,
etc.
For all the machines listed, we recommend type HF 150,
asits low elongation, high strength and sufcient elasticity
largely neutralize any impacts and vibrations that occur.
Type HF 075 is especially useful when high precision is
required where smooth running and tolerances are con-
cerned. It is therefore used for computers and ofce equip-
ment as well as small devices.
In addition. the HF 075 can be used for small conveying
applications.

takes into account the type
of drive and driven machine. It applies exclusively to
two-pulley drives and for a daily operating time of less than
ten hours. No special conditions have been taken into
account. Please observe the additional factor c
4
.
Since it is practically impossible to condense every possible
combination of drive unit, driven machine, and operating
conditions into a standard-compliant short version, the drive
service factors are guide values. ln special cases,
e.g.increased starting torque (direct starting with fans),
drives with a high switching frequency, extraordinary im-
pact load, considerable mass acceleration and deceleration,
the drive service factor must be increased.
In cases of doubt. we recommend that you contact our
consulting engineers.

Tension of at belts
The correct level of belt tension is of enormous importance
for trouble-free transmission of power and for achieving an
acceptable belt service life.
Often tension which is either too high or too low results in
early belt failure. A belt which is over tensioned often
causes bearing failure in the drive or driven machine.
It has been shown that common tensioning instructions, such
as using the “thumb pressure deection method”, are not
suitable for obtaining optimum tension for operating at full
efciency.
Over or undertensioning of the drive can be avoided if the
tension is calculated, set or checked according to the
following method.
Tension through span force
An optimum tension is achieved if a span force of 300 N
per 10 mm belt width is applied for type HF 150.
This belt tension approximately corresponds to an elonga-
tion of 0.7% of the belt length.
Type HF 075 can be tensioned according to the same
method, with the exception that the span force is 150 N per
10 mm belt width and an elongation of 0.8 % of the belt
length can be expected.
The span force can easily be checked on a belt width of up
to 50 mm with the aid of optibelt TT using the frequency
measuring method. If the frequency has been determined,
the span force can be calculated as follows:
T = 4 · k · L
2
· f
2

k = Weight per metre per mm belt width [g/m]
L = Belt tension [m]

Checking the tension with a length addition value
The length (L) of the relevant at belt is measured in an
untensioned condition on the top surface of the belt.
Calculate the length addition value “A” by using the
formula:
A = L · R (elongation value)
R = 0.007 for type HF 150
R = 0.008 for type HF 075
This length addition value A should then be added to the
measured length.
The at belts are now tensioned until the calculated length is
reached (length + length addition value A). The belt is then
correctly tensioned.
If the drive is to be retensioned, the belt must rst be
slackened off so that it can be measured in a tension-free
state.
After that. follow the procedure described above.
A = Length addition value [mm]
L = Length of at belt [mm]

FLAT BELT PULLEYS
STANDARDS – SELECTION CRITERIA – TYPES
Flat belt pulleys are an essential part of the at belt drive.
They are mainly manufactured of GG 20 cast iron accord-
ing to DlN 1691 and supplied with a pilot hole, pre-fabri-
cated hole or with a clamping bush system. Other materials,
such as steel oraluminium can also be used depending on
the drive conditions.
When selecting the at belt pulleys, the following must be
adhered to:
• Use standardized pulley diameters. If this is not possible
forstructural reasons, a standardized diameter should be
selected for the largest pulley.
• Do not use less than the minimum pulley diameter in the
interest of the belt lifetime and the efciency of the drive.
Minimum pulley diameter
Type HF 075 = 6 mm
Type HF 150 = 15 mm
• If users produce their own at belt pulleys, a standard-
compliant design and nish must be ensured (DIN 111).
• Flat belt pulleys are generally balanced on a level
(
statically), quality grade G 16, according to VDI 2060.
•

becomes necessary if:
1. v > 30 m/s or
2. The ratio of diameter to pulley face width
is d : b < 4 with v > 20 m/s.
• Flanged pulleys should be avoided if possible.
Pulley face widths
When selecting at belt pulleys, a suitable width must be
ensured. The following rule applies: Belt width plus 10%.
Pulley type
The at belt pulley should be of cylindrical or
curved
design.
When using

Idler conguration
In principle, idlers can be used as inside or outside idlers
depending on the drive situation.
Unless design requirements call for an outside idler, the
inside idler is usually more advantageous. Its diameter can
be kept smaller than that of the outside idler.
Depending on the belt type, inside idlers can either be
grooved or at pulleys.
SPECIAL DRIVES
TENSION/GUIDE IDLERS
Idlers are grooved or at pulleys that do not transmit any
power in a drive system. Due to the fact that additional
exing stress is created in the belt, it is recommended that
idlers are only used sparingly under the following conditions
if possible:
• with xed drive centres in order to produce the required
tension and to take up the maximum possible belt stretch
and wear.
• as an idler pulley when dealing with extremely long free
belt spans that are subject to twisting.
• as outside idlers where the arc of contact on one of the
loaded pulleys is too low. Their inclusion increases the arc
of contact and often reduces excessive slip or eliminates
the need to increase the number of belts.
• as idler pulleys and guide idlers on drives where pulleys
are not all on the same plane such as quarter turn drives.
• to guide belts past obstructions.
• as pneumatically, hydraulically or spring loaded idlers to
maintain a constant tension.
• as clutching idlers with which the driven pulley can be
engaged or disengaged. Complex clutches are no longer
required. Because of their single belt characteristics,
optibelt KB kraftbands are particularly suited for these
applications.
If, for the reasons listed above, it is absolutely essential to
employ idlers, the following criteria should be considered
when designing the drive:
• idler conguration
• position of the idler in the belt span
• idler diameter
• idler design
• adjustment allowance of the idler for installation and
initial and subsequent tensioning of the belt
• correction of the power rating P

Inside idlers reduce the arc of contact on the loaded pulleys
and with it the arc of contact correction factor c
1
. When
calculating the number of belts, the arc of contact correction
factor should be selected for the position of the idler at the
point of maximum belt stretch (see table 81, page 137).
Outside idlers generally have to be at pulleys as they
are running on the back of the belt. They increase the arc of
contact. Care must be taken to ensure that the maximum
possible belt stretch is taken up and that contact with the
opposite span is prevented. The reverse bending caused by
outside idlers will lead to a reduction of the belt service life.
Special V-belt constructions on request.

Fig. 3
On drives with long belt spans, grooved pulleys are the
preferred choice for inside idlers because with at pulleys
transverse vibrations and belt turnover can occur.
Minimum diameter for idlers
Inside idlers should not be smaller than the recommended
minimum pulley diameter (d
d min
) for the belt section
concerned (see page 49, table 14)
Inside idler ≥ minimum pulley diameter for the belt
section concerned
The presence of an outside idler exposes the belt addition-
ally to a varying bending load. Due to this load, outside
idlers must be at least 1.35 times greater than the minimum
pulley diameter for the particular belt section.
Outside idler ≥ 1.35 · min. pulley diameter for the belt
section concerned
The belt service life is signicantly reduced if the minimum
recommended idler diameter is less than the recommended
size. The use of an Optibelt special construction can
signicantly improve service life.
Idler design
Grooved pulleys which are used as idlers can usually have
standard groove dimensions. On drives with too severe
vibration and long drive centre distances, it is recommended
that deep grooved pulleys are used.
Flat pulleys should, if possible, be cylindrical and not
crowned. Flanged pulleys are recommended as belt guides.
The edges formed by the contact surface and pulley ange
should be sharp. Round edges encourage the belt to run on
the anges causing it to turn over.
SPECIAL DRIVES
TENSION/GUIDE IDLERS
Position of the idler in the belt span
Theoretical power transmission formulas and actual practice
have shown that idlers should, wherever possible, be placed
in the slack side of the drive. The tension idler force can be
reduced very signicantly then. A spring loaded idler must
not be employed in a reversing drive as the slack and tight
sides of the drive are constantly changing.
Our Application Engineering Department will be pleased
toassist you when spring loaded idlers present special
problems.
Fig. 1
Grooved pulleys can be used as inside idlers anywhere on
the slack side. Where possible, however, the arc of contact
should be the same on both pulleys when the idler reaches
its end position, i.e. belt stretch is at its maximum.
Fig. 2
Flat pulleys, whether used as inside or outside idlers, are to
be placed as far as possible away from the grooved pulley
on to which the belt runs next. Any alignment errors be-
tween the idler and the pulley and the resultant sideways
movement of the belt on the pulley are thus avoided.

Calculating the length and determining the number of belts

3. The next largest standard length L

selected. A check should be made, usually on the
drawing, to determine whether the belt can be
adequately tensioned with the idler in the outermost
position. In this idler position, both the standard length

and the double adjustment x must be taken up
(seepages 80/81).

Number of belts
The use of idlers increases the bending stress in the belts.
Toavoid a reduction in belt service life, the idler correction
factor c

must also be included in the calculation. This
correction factor takes into account the number of idlers that
are larger than the minimum diameter.

per belt is, as before, based
on the smallest loaded pulley.
Calculation of the arc of contact correction factor c

SPECIAL DRIVES
TWIST DRIVES
The required inclination of the shafts and the pulleys relative
to each other and the belt entry and exit angles should be
conrmed by practical tests. In addition, certain critical
drives may have a considerably improved safety factor if
special constructions by Optibelt are used. The most impor-
tant types of twist drives and the according design guide-
lines are illustrated below.
Drives with crossing belt spans are often simply termed twist
drives. These can be drives where the shafts are not paral-
lel, whose pulleys and idlers are not all arranged on one
plane, or drives with two parallel but counter rotating shafts.
Because of the twisting of the belt, this type of drive requires
a certain degree of lateral bending exibility. Due to the
cross section of V-belts, at belts are better suited for this
application. In most cases twist drives use single V-belts, but
drives using belt sets are also possible. The crossing of the
belt spans and the non-aligned entry of the belt into the
pulley leads to a reduction of the belt service life. The entry
and exit angle between the belt and the pulley plane should
not be more than 5°.
Quarter twist drive – ratio i or 1 : i < 2.5
Quarter twist drive
The term quarter twist drive is used to describe systems
where the shafts are at an angle of 90° to each other.
The ratio i or 1 : i of quarter twist drives should not
exceed2.5.
Where this is not possible, a two stage drive should be
employed, in which one stage is a standard V-belt drive.

2. The drive must be aligned in such a way that a straight

4. The direction of rotation must be arranged so that the
tight side S

5. Deep grooved pulleys should be specied if possible for
single belt drives. This ensures an improved entry and
exit of the belt, thus preventing turnover.
6. Never specify deep grooved pulleys when using kraft-
bands. Kraftband pulleys should always be used. We
recommend, in any case, consulting our Application
Engineering Department.
7. When calculating the number of belts, the examples
given on pages 83 to 85 should be followed. An arc of
contact correction factor c

8. The static belt tension “T“ should be calculated using the

belt can be tted without force, the necessary tension can
be applied and the belt stretch and wear can be taken
up during its service life.

Applications areas
The advantages of Optibelt V-belts and kraftbands with
aramid tension cords are best applicable where
• high power transmission is required
• there is only small installation space
• there is little adjustment range
• high temperature inuences occur
Thus, with the same number of belts and unchanged drive
parameters, signicantly higher power levels can be
transmitted without reducing the service life of the belts.
Even drive constructions that have previously had to be
classied as critical may now be considered risk free. From
now on, load limits apply as safety buffer zones; minimal
belt stretch results in virtually maintenance-free running.
For these reasons Optibelt V-belts and kraftbands with
aramid tension cord are to be found on drives with excep-
tional loading requirements –
• on critical drives in industrial applications
• on special machines
• on agricultural machinery
• on horticultural machinery
Attention: With two-pulley drives, particular requirements
are placed on the shafts and bearings. It is recommended to
use spring-loaded idlers (inside/outside idlers) with aramid
V-belts / aramid kraftbands.
A discussion of all the relevant criteria would be beyond the
scope of this manual. We therefore recommend contacting
our Application Engineering Department to discuss your
special requirements.

Aramid is an organic polyamide bre that is manufactured
in a complex chemical process. It may be used wherever
maximum stress resistance and reliability are required. The
processing of this bre requires the highest level of experi-
ence and know-how as well as sophisticated testing facili-
ties. Aramid is used as the tension cord material for highly
loaded V-belts and kraftbands.
Structure and properties
Compared to materials commonly used for tension cords
e.g. polyesters, aramid stands out due to its extremely
low-stretch properties.
Its tensile strength is twice as high as that of a standard bre
in the same thickness.
Despite its extreme strength, this bre is remarkably exible
and has sufcient elasticity to absorb shock loads or
vibration.
These properties, which are of special importance for V-belts
and kraftbands, result in huge improvements in comparison
to conventional constructions.
Optibelt V-belts in aramid cord structure comprise:
The high quality, specially processed aramid tension cord is
embedded in a special rubber compound. The upper and
substructure are thus supported effectively. These consist of
a bre reinforced polychloroprene rubber compound. The
cover fabric is treated with a rubber compound on both
sides and covers the whole belt.
Special applications can also be designed with raw edge
V-belts and kraftbands employing aramid tension cords.
Drive calculation
Calculation should follow the example given on
pages 83 to 85.
Please ask for the higher power ratings.

BELT TENSION FOR OPTIBELT V-BELTS
For proper power transmission and for achieving an
acceptable belt service life, the correct belt tension is of the
utmost importance.
Too low or too high belt tension will lead to the premature
failure of the belts. Over tensioning often leads to bearing
failure on the driver or the driven machine. Experience has
shown that unscientic belt tensioning methods, such as the
“thumb pressure method”, are not suitable for applying the
optimum tension to the drive for maximum efciency. It is
therefore recommended that for each drive the required
static belt tension “T” is calculated using the formulas by
Optibelt. This tension is the lowest possible required by
adrive to transmit the highest power level from the drive,
taking account of the normal amount of slip.
Once the belt has been tted and the initial tension has
been applied, it should be checked using an Optibelt
tension gauge.
The belt should be monitored regularly during the rst hours
of operation. Experience has shown that the rst re-tension-
ing should be carried out after approximately 30 minutes to
four hours operating under full load. In doing so, the initial
stretch is absorbed.
After approximately 24 hours of operation, it is often
recommended to check the drive and re-tension the belts
ifnecessary, particularly when not continuously run under
full load. The time between checks can be signicantly
increased then. Also see our installation and maintenance
advice on pages 156 to 157.
Too high or too low tension of the drive will be avoided if
the belt tension is calculated, set and checked using one of
the following methods.
I. Checking the belt tension by span deection
This method provides an indirect measurement of the
calculated or actual static belt tension. It is applicable

Calculation of the static belt tension using the following formula:
During new installation, the drive is to be tensioned

3. Calculate the belt deection for a given span length E
a
for the actual drive span length L.
Apply test load “f“ (taken from diagrams 8 to 11 for the
appropriate belt prole) to the centre of, and perpendicu-
lar to, the span as illustrated above. Measure the deec-
tion and if necessary adjust the centres until the correct
belt tension is achieved.
II. Checking the belt tension
via speed measurement
This method checks belt tension using the theoretical slip.
The speed of the driver and driven pulleys are measured
rst in an unloaded condition and then under load.

Belt tensioning via
”length addition value” method
It has become evident that span deection methods are
not ideal for checking the tension of kraftbands of all
proles. and of individual belts. The following, very
simple method for the setting and checking of belt tension
is therefore recommended:
1. Calculation of the static belt tension “T“:
Example:
P
B
= 1136 kW
c
1
= 0.97
v = 25.91 m/s
Drive arrangement with one set comprising:
2 optibelt KB kraftbands 4-8V 3750/25J 9525 L

500 · (2.04 – 0.97) · 1136
0.97 · 18 · 25.91
+ 0.69 · 25.91
2
= 1807 N
2. Measure the setting length “M“ of the kraftband or the
single belt, on the top surface of the kraftband or on the
belt top surface when not tensioned. However the belt
can be measured when tted to the drive, provided that it
is completely without tension.
3. Procedure
a) Install the kraftband or the single belt on the pulleys.
Provisionally tighten the belt in order to seat it into the
pulley grooves.
b) Next, completely slacken the kraftband or the single belt.
c) Mark two lines on the top of the belt, with distance
“M“. The lines must be marked on the free span
length, not where the belt is on the pulley (“M“ should
ideally be 1000 mm minimum or a multiple of it).
Important: The longer the measured prole, the more
accurate the tension setting will be.
4. Calculate the length additional value “A“ using the formula:
A =
M · R
1000
R = stretch factor from table 84 page 147
5. Tighten the kraftband or the single belt until the length
calculated under point 4 is reached. The drive is now
correctly tensioned.
6. If the drive has to be re-tensioned, the belts have to be
slackened rst so that they can be re-measured complete-
ly free of tension. After that. the procedure described in
paragraphs 3 to 5 applies.
Tighten the kraftband until the length additional value is
reached. This will set the correct tension.
At initial installation, the static belt tension must
be multiplied by 1.3.

CALCULATING THE AXIAL LOAD/SHAFT LOAD
UNDER DYNAMIC CONDITIONS
Using drives that have electric motors as drive machines
and are/or will be designed according to DIN2211 Part 3,
ensures that the dynamic stress that occurs can be absorbed
by the appropriate shafts and bearings of the motor.
However drives with
• electric motors out with the DIN standards
for the determined dependencies of pulley diameter
andpower.
• combustion engines.
• turbines as well as
• heavy duty drives such as stone crushers, calenders or
heavily loaded mills
have been found to require determination
of the dynamic bearing load, i.e. the loads that
occurfor shafts and bearings on the input or output drive
units.
Precise calculation of the “Dynamic axial load“ prevents
unnecessary costs due to
• premature failure of the bearing.
• breaking of the shaft.
• over dimensioned bearings and shafts.
In the case of 2-pulley drives, the driver and driven shafts
and the bearings are subjected to the same dynamic axial
force, but in opposite directions. When idlers are employed,
the magnitude and the direction of the axial force are
almost always different on each pulley. If the magnitude and
direction of the dynamic axial force is to be determined, a
graphical solution, using a vector diagram for the dynamic
forces in the tight side S
1
and the slack side S
2
. is recom-
mended.
If only the magnitude of the dynamic axial force has to be
determined, this can be achieved using the formula for
“S
adyn
“. Both procedures will be illustrated in the following
example.

optibelt OPTIKRIK TENSION GAUGES
This gauge offers a simple method
of belt tensioning.
It helps e. g. mechanics during the maintenance of belt
drives when technical data is not known and the optimum
tension therefore cannot be calculated. This method requires
only knowledge of the diameter of the small pulley and the
belt prole. The Optibelt tension gauge is used to directly
read the belt tension. By reducing or increasing the belt
tension the desired value is achieved.
For different tensioning values, optibelt OPTIKRIK 0, I, II, III
with corresponding measurement ranges are available.
Instructions for use
1. The gauge is placed in the middle between the two
pulleys on the back of the belt, in the case of sets of belts
ideally on the belt in the middle. (Before doing so, please
press the indicator completely into the gauge body.)
2. Place the gauge loosely on the belt to be measured and
slowly press a nger onto the pressure surface.
3. Try not to touch the gauge with more than one nger
during the measuring process.
4. When you feel or hear a denite “click”, immediately
release the pressure, the indicator arm stays in the
measured position.
5. Carefully lift the gauge without moving the indicator arm.
Read the belt tension (see g.). Read the measurement at
the exact point where the top of the indicator arm crosses
the scale.
6. Reduce or increase the belt tension according to the
measurement result until it is within the desired tension

INSTALLATION AND MAINTENANCE SUPPORT
Safety: Before starting any maintenance work, it is extremely important that any machine
components are in a safe position which cannot be changed during maintenance
work. In addition, safety recommendations of the manufacturer are to be strictly
observed.
optibelt KS V-GROOVED PULLEY WITH TAPER BUSH
3. Clean and degrease the shaft. Push pulley with
taper bush to the desired position on the shaft.
See alignment of the V-grooved pulley.
4. When using a key, it has to be inserted in the
hub of the shaft rst. Between key and bore hub
there needs to be a certain tolerance.
5. With a socket wrench according to DIN 911
stud screws and/or cap head screws have to
be tightened equally using the tightening torque
stated in the table.
6. After a short operating time (0.5 to 1 hour)
check tightening torque of the screws and cor-
rect if necessary.
7. In order to prevent the entering of foreign sub-
stances, ll empty connection bores with grease.
The V-grooved pulleys are to be
checked for damage and correct di-
mensions before installation.
Installation
1. All shiny surfaces like bore and tapered surface
of the taper bush as well as the tapered bore of
the pulley have to be cleaned and degreased.
Insert taper bush in hub and align all connecting
bores. Half tapped holes have to face half plain
bores.
2. Stud screws (TB 1008-3030) and/or cap head
screws (TB 3525-5050) should be slightly
greased and screwed in. Do not yet tighten the
screws.

HORIZONTAL ALIGNMENT OF SHAFTS
Motor and drive shafts are to be aligned using a spirit level, if necessary.
Note!
Maximum shaft deviation 0.5°
VERTICAL ALIGNMENT OF THE V-GROOVED PULLEYS
The alignment of the V-grooved pulleys is checked before and after tightening
the taper bushes with an alignment rail.
Note!
Check whether the face widths of the V-grooved pulleys have the same sizes.
A possible deviation of the face width has to be taken into account. With a
symmetrical face set-up, the distance of the parallel, to the smaller face is half
the deviation.

BELT TENSION
Use belt tensioning values according to Optibelt recommendations. Set the belt
tension with parallel motor and machine shafts. Operate the belt for some
rotations and check the belt tension again. In our experience, belt tension
should be checked again after an operating time of about 0.5 to 4 hours and
then be corrected, if necessary.
For further information about belt tensioning see page 151-153.
DRIVE CHECKING
We recommend checking the drive regularly. e.g. after each 3 to 6 months.
V-grooved pulleys are to be checked for wear and consistency. Use the
Optibelt prole and V-groove gauge tools.
When changing V-grooved pulleys with taper bushes (see g. on page 158)
the following aspects have to be observed:
1. Loosen all screws. Unscrew out one or two screws depending on the bush size. grease them and
screw them into the set bores.
2. Tighten the screw or screws equally until the bush releases from the hub and the pulley can be
moved freely on the shaft.
3. Remove the pulley with the bush from the shaft.
** Prole and V-groove gauge
INITIAL INSTALLATION
Always install the V-belts without force. Installations using screw drivers,
crowbars etc, cause external and internal damage to the belt. V-belts installed
under force might only run for several days. A proper installation of the belt
saves time and money.
If the installation space is too small, the V-grooved pulleys with belts should be
slid onto the shafts.

STORAGE
• Storage length
Properly stored drive belts retain their quality and proper-
ties for a period of up to 6 years if the following conditions
are met.
However, when stored under adverse conditions or
handled incorrectly, the physical properties of most rubber
products will be impaired.
• Storage area
The storage area should be dry and dust-free. Drive belts
must not be stored together with chemicals, solvents, fuels,
lubricants, acids, etc.
• Temperature
Drive belts should be stored at temperatures between
+15 °C and +25 °C. Lower temperatures usually have no
negative effect on the drive belts. However, since belts
may become very rigid at low temperatures, they should
be warmed to approximately +20 °C before installation
and use to avoid breaking and cracking. Radiators and
supply pipes must be shielded. Drive belts should be
stored at least 1 metre away from heat sources.
• Light
Drive belts should be protected from light, especially direct
sunlight and strong articial light with high ultraviolet
radiation (ozone formation) such as naked uorescent
tubes. The use of suitable room lighting is advisable.
• Ozone
In order to counteract the harmful effects of ozone,
storage rooms must not contain any appliances that
generate ozone, such as uorescent lights, mercury
vapour lamps or high-voltage electrical equipment.
Combustion gases and vapours which could lead to the
formation of ozone by photochemical processes, must be
avoided or eliminated.
• Moisture
Damp storage areas are unsuitable. Care must be taken
to ensure that condensation does not develop. The most
favourable relative air humidity is below 65 %.
• Proper storage
Because stress can promote both permanent deformation
and cracking, care must be taken to ensure that drive
belts are stored without stress i.e. without tension, com-
pression or any other form of pressure. If V-belts have to
be stored horizontally and stacked on top of each other,
it is recommended that the stack height does not exceed
300 mm in order to avoid permanent deformation. If,
in
order to save space, drive belts are hung
, the diameter of
the cylinder on which the belts rest should be at least ten
times the height of the belt prole.
• Cleaning
Dirty rubber drive belts can be cleaned using a 1:10
mixture of glycerine and methyl spirits or with brake
cleaner. Petrol, benzene, turpentine, or similar should not
be used.
In addition, sharp objects, wire brushes, emery paper etc.
must be avoided under all circumstances, as these can
cause mechanical damage to the belt.
• Reference to standards
Further information can be found in DIN 7716.
optibelt S=C Plus and optibelt M=S belts do not
need to be stored in sets as they can be used in
sets without measuring.

LENGTH MEASUREMENT CONDITIONS
AND CONVERSION FACTORS
Belt length measurement
The belt is placed over two identically sized measuring
pulleys of the groove design shown in the following draw-
ings. The dimensions are given in the tables 85 to 91 on
pages 167/168.
By moving to the adjustable pulley the force Q is applied on
the belt. Before measuring the drive centre distance a, the
belt should be rotated three times under load. This ensures
that the belt is well seated in the pulley, an essential
pre-condition for the accuracy of the resulting measurement.
The length is obtained by adding the diameter of the pulley

PRODUCT DESCRIPTION
Optibelt has developed a series of conveyor elements for
the economical conveyance of goods in a varied range of
applications.
• optibelt PKR endless V-belts DIN 2215 with
patterned top surfaces
• optibelt PKR endless V-belts DIN 2215 with
lightcoloured fabric cover and
patterned top surfaces within the
standard belt height
• optibelt KB kraftbands with patterned top
surfaces
• optibelt optimat PKR open-ended V-belts DIN 2216 with
patterned top surfaces
• optibelt optimat FK open-ended conveyor belts.
punched
• optibelt optimax HF high performance at belts
Construction/Quality
Optibelt conveyor elements consist of the basic belt and the
top surface. These parts are specially connected via vulcani-
sation. The variety of applications required constructions
with numerous patterns available in different qualities. Both
pattern and surface quality should be adapted to the
individual application.
Table 97
CR/black is available as standard. We would be pleased to
inform you about the production of the other constructions.
SBR = Styrene-Butadiene-Rubber
NR = Natural Rubber
CR = Chloroprene Rubber
* ≈ 55 for top surfaces above the standard height
** ≈ 65 for top surfaces within the standard height
Properties
Special surfaced belts are used instead of expensive
conventional type conveyor belts. They run individually, or
in sets arranged adjacent to each other. transporting goods
horizontally. or inclined up or down. Vertical conveying is
also possible if the belts are arranged top surface to top
surface, gripping the goods between them.
Applications areas
Here are just a few examples of the wide range of applica-
tions in which Optibelt conveyor belts are used successfully.
For the conveyance of:
• doors. cupboard parts. veneer and plastic panels in the
woodworking industry
• body parts and sharp-edged sheet metal in the automotive
industry
• cardboard and boxes in the packaging industry
• roof tiles, concrete slabs and block paving stones
• tiles
• at glass
• postal items
• bowling balls on bowling lanes
In addition to the conveyance options, these belts are also
used for
• labelling and sealing of tins and jars in the canning
industry
• lifting, chopping and sorting of beet, potatoes, salad, cau-
liower, Brussels sprouts and other vegetables in the
agricultural industry
Due to their single belt characteristics and high surface
load, optibelt KB kraftbands with patterned top surfaces are
especially suitable in conveyor systems and lifting platforms
for:
• the conveyance of cargo containers
• loading and clearing of airplanes and railway wagons
• stowing and unloading of ship cargos

CONVEYOR ELEMENTS
DESIGN GUIDELINES
Drive and guide pulleys
The drive and guide pulleys should be V-grooved pulleys.
The minimum diameters should be selected according to the
standard recommendations for V-belts and kraftbands. See
the chapter on V-grooved pulleys.
Due to the relatively low transporting speed (experience has
shown that it is usually less than 1m/s) and the resulting low
ex rate, pulley diameters can be reduced to approximately
10 % below the recommended minimum. With greater
reduction, there is danger that the top surface separates
from the V-belt base.
The driver pulley should be arranged at the discharge end
of the conveyor so that the goods are pulled along.
Support idlers/tracks
In most cases. support idlers or tracks are
required to prevent the belt from sagging under
load.
Support idlers may be at faced or V-grooved
pulleys. The dimensions of the pulley grooves
should support the base of the conveyor belt in
the base of the groove so only one edge can run
on the groove ank, and thus cannot get stuck in
the groove.
The diameter and the number of support idlers required
depend on the length of the conveying span and the weight
and size of the goods to be conveyed.
Supporting tracks, generally made of plastic, are either at
or with a key seat to improve guidance of the conveyor belt.
As with the support idlers, the grooves must have an
adequate width.
Adjustment of the drive centre distance allowances
The tables on pages 80 to 82 show the drive centre dis-
tance allowances for special purpose conveyor belts and
kraftbands.
Tensioning options
An adequate belt tension is essential to
the reliable operation of the conveyor
system. Tension is applied by adjusting
the drive centre distance or, when the
centres are xed, by tension idlers.
When idlers are employed, they should
be arranged inside the belt if possible,
as otherwise the alternating exing of
the belt will reduce its service life.
