encapsulates the tensile cords and protects
them from contaminants and mechanical
damage e.g. from idler pulleys on the
back of the belt.
C
Belt teeth are precisely formed
and accurately spaced to ensure
quiet, efficient engagement
with pulley grooves.
They are made of medium hardness chloroprene and
are bonded integrally with
the belt backing.

Pitch Length
The three principal dimensions of a belt are:
pitch
pitch length
width
and are used in this order as a designation e.g.
8MXP-1120-30.
Belt pitch is the distance in millimetres between two
adjacent tooth centres as measured on the pitch line
of the belt.
Belt pitch length is the total length of the belt
(circumference) in millimetres as measured along
the pitch line. The theoretical pitch line of a belt lies
within the tensile member.
TEMPERATURE
Torque Drive Plus 3 belt performance is generally
unaffected in ambient temperatures between
–25OC and +100OC. Temperatures beyond these
extremes should be referred to your local Authorised
Distributor.
ANTI-STATIC AS STANDARD
Fenner Torque Drive PLUS 3 belts are static
conductive to the definitive ISO 9563 (1990)
as standard.

TDP3 DRIVE SELECTION PROCEDURE
EXAMPLE
1) Determine Drive Requirements
1) Drive Requirements
a)
b)
c)
d)
The nature of the driving machine (usually the prime mover) and the driven
machine and the duty cycle in hrs./day.
The rotational speeds of the driving and driven machines.
The power capability and starting arrangements of the prime mover and the power
absorbed by the driven machines.
The required drive centre distance and the machine shaft diameters.
a) AC cage rotor electric motor driving to a rotary gear pump. 24 hr/day.
b) 1450 rev/min motor, pump to run at 740rev/min +/–5%.
c) 60 kW motor, soft start – no pump absorbed power given.
d) Centres 800/850mm, motor shaft 60mm, pump shaft 75mm.
2) Design Power
2)Calculate Design Power
Service factor for medium duty, soft start, 24 hr/day = 1.7.
Select a service factor from the table – page 92. Include an additional factor if the
drive is speed increasing.
Design power = 1.7 x 60 = 102 kW.
Multiply normal running (absorbed) power by the service factor to give design
power – kW.
3) Belt Pitch
Use the belt pitch selection guide - page 91 to select 8mm or 14mm pitch
according to the point of intersection of the small pulley (faster shaft) rotational
speed and the design power.
3) Belt Pitch
Pitch selection chart shows intersection of 1450 rev/min and 102 kW to be within the
capability of 14mm pitch.
4) Speed Ratio
1450/740 = 1.97:1
A 2:1 ratio satisfies the +/–5% criterion.
If the intersection lies close to the 8/14mm pitch boundary, either pitch may be
appropriate, attempt the design procedure on 8mm pitch first but be aware that
later criteria may make 14mm necessary.
5) Pulley Selection
4) Speed Ratio
6) Belt Length & Centre Distance
Divide the rotational speed of the faster shaft (rev/min) by that of the slower shaft to
determine speed ratio.
A belt length of 2310mm gives centres of 816mm.
5) Pulley Selection
The power rating table shows a value of 46.74 kW for a 32 groove pulley at 1450 rev/min
for a 40mm wide belt.
Refer to the drive tables (pages 96-103) for the appropriate belt pitch. From the
first column select the required speed ratio and consult the next two columns for
appropriate pulley groove numbers.
Where alternative groove number pairs are available be aware that criteria in steps
6 & 7 may influence the ultimate selection.
Consider any drive dimensional limitations by reference to
pulley dimension tables on pages 104-106, noting that pulleys with up to 72
grooves may have flanges that determine the o/dia.
6) Belt Length & Centre Distance
Read along the line in the drive table for the selected pulley groove number pair
and select the centre distance closest to that required. The standard belt length
giving that centre distance is at the head of the column.
If centre distance is critical, be aware that alternative groove number pairs may
offer a closer value with standard belt lengths.
From page 102, 32 to 64 grooves is one combination giving 2:1 ratio.
7) Power Rating & Belt Width
Belt length factor for a 2310mm belt = 1.0 - no change to power ratings.
102/46.74 = 2.18. Next larger standard width factor = 2.31 for 85mm wide belt.
8) Shaft Sizes
The 32-14M-85 pulley uses a 2517 Taper Lock bush, max. bore 60mm – OK.
The 64-14M-85 pulley uses a 3525 Taper Lock bush, max. bore 100mm – OK.
DRIVE SPECIFICATION
Motor pulley:
32-14M-85 HTD pulley.
Taper Lock bush:
2517/60mm.
Driven pulley: 64-14M-85 HTD pulley.
Taper Lock bush: 3525/75mm.
Belt: 14MXP - 2310-85 Torque Drive PLUS 3 belt.
7) Power Rating & Belt Width
Refer to the power rating table on page 91 for the chosen belt pitch, locate the
small pulley groove number/rotational speed combination, and note the power
rating (for the narrowest standard belt width).
Multiply this rating by the belt length factor for the chosen belt length, from the
listing beneath the main table.
Divide the design power by the length corrected power rating, to give required
belt width factor. Refer to the width factors below the rating table and select the
belt width with a factor equal to or greater than required.
8) Shaft Sizes
Check the bore capacity of the chosen pulleys against the pulley dimension tables
on pages 104-106.
90
DRIVE ORDERING INSTRUCTIONS
A complete drive usually consists of five components:
Two pulleys, two Taper Lock bushes and one belt.
1. Pulleys. Standard HTD pulleys. Codes are shown on the dimension tables,
pages 104-106.
2. Taper Lock bushes. Bush sizes are shown on the pulley dimension tables. Bush
codes are on Shaft Fixings pages 129-130.
3. Belts. Belt codes are shown on page 105-106.
The drive selection above would be ordered as:
If the pulleys will not accomodate the drive shafts it will be necessary to consider
other pulley combinations, possibly using an alternative belt pitch.
Driving pulley
32-14M-85
Code 043R0032
Taper Lock bush
2517/60mm
Code 029M0060
NOTE
Driven pulley
64-14M-85 Code 043R0064
An optimum drive will use a belt of width factor just greater than that required. If alternative groove
number pairs can give close to the required speed ratio, slightly larger pulley groove numbers may
allow a narrower belt, or slightly smaller groove numbers may be possible with the same belt width.
Larger diameter pulleys typically reduce bearing and shaft loads. Avoid drives where the belt width
exceeds the small pulley diameter.

PULLEYS
The three principal dimensions of a pulley are:
number of grooves pitch
width
and are used in this order as a designation e.g. 72-8M-50.
(flange diameter will
be greater)
On the pulley, pitch is the distance between groove centres and is measured on
the pulley pitch circle.
The pitch circle of the pulley coincides with the pitch line of the belt running in it.
The pulley pitch diameter is always greater than its outer diameter.
Torque Drive PLUS 3 belts run with standard Fenner Taper Lock HTD pulleys.
Standard pulley dimensions are listed in the tables on pages 104-106.

BELT PITCH SELECTION CHART
This development of the original Timing Drive is offered in a range of pitches
5mm, 8mm and 14mm. Comprehensive choice of belt widths and lengths
combine with an optimised range of Taper Lock pulleys to suit general
industrial needs.

Drives can be designed by simple catalogue selection methods to give more
compact drives, less noise and lower bearing loads than with classical Timing
Drives.
Fenner HTD belts have a curvlinear tooth form giving a more uniform
distribution of shear stresses within the teeth and a transition of tooth loads
to the tensile members in the belt which significantly improves upon classical
Timing Belts.

Temperatures beyond these extremes should be referred to your local Authorised
Distrbutor.
For storage, belts should be protected from moisture, temperature extremes,
direct sunlight and high ozone concentrations.
Belts should be stored avoiding sharp bends or crimping, which would damage
the belts.

HTD Drives
HTD Drive Design
HTD SELECTION PROCEDURE
(a) Speed Ratio
Divide the rev/min of the faster shaft by the rev/min of the slower shaft to obtain
the speed ratio.
(b) Service Factor
From the table (page 92) select the service factor which is applicable to the drive.
If the drive is speed increasing an additional factor may be required.
(c) Design Power
EXAMPLE
An HTD drive is required to drive a rotary pump at 685 rev/min. The prime mover
is a 30kW, direct-on-line start AC motor, running at 1440 rev/min. The required
centre distance is 450mm, and each shaft diameter is 55mm. Continuous duty.
(a) Speed Ratio
1440
= 2.10:1.
685
(b) Service Factor
From table (page 92) the service factor is 1.9.
Multiply the normal running power (kW) by the service factor. This gives the
design power which is used as the basis for selecting the drive.
(c) Design Power
(d) Belt Pitch
(d) Belt Pitch
Refer to the belt pitch selection chart on page 93. Choose the recommended belt
pitch according to the point of intersection of the design power and the rev/min of
the faster shaft.
From table on page 93, 14M is the most suitable pitch.
(e) Pulley Selection
Refer to the drive tables (pages 96 to 103) for the pitch of belt selected in (d).
From the first column select the required speed ratio. Reading along the same
horizontal line the next two columns give the number of grooves on each pulley.
Where more than one combination of pulleys is available consult the power
ratings tables (page 95) and the list of stock belt widths (page93). In conjunction
with the design power found in (c) determine the most suitable pulley pair.
(f)Centre Distance
Design Power = 30 x 1.9 = 57kW.
(e) Pulley Selection
A speed ratio of 2.11 can be found in the drive tables on page 102 utilising
pulleys of 38 and 80 grooves.
(f)Centre Distance
Reading along the same line as the 2.11:1 Speed ratio, a centre distance of
467mm is found, and at the head of the column the belt length given is 1778mm.
(g) Belt Length Correction Factor
From table on page 95 Belt Length Correction Factor = 0.95.
Using the relevant drive table read along the same horizontal line as that showing
the pulley sizes, and select a centre distance nearest to that which is required.
The belt required to give this centre distance is shown at the head of the column.
(h) Power Rating
From the power rating table the basic capacity of a 38 groove pulley at 1440 rev/
min is 25,70kW/40mm width. Actual power rating = 25.70 x 0.95 = 24.41 kW.
(g) Belt Length Correction Factor
(j) Belt width
Belt Width Factor =
From the table on page 95 note the correction factor for the pitch and length of
belt chosen.
(h) Power Rating
57
= 2.33
24.41
From the width factor table beneath the power rating table it can be seen that the
required width is 85mm.
Refer to the Power Ratings on page 95 for the pitch of belt being considered.
Read down the left hand column to the speed of the small pulley in rev/min. On
this line read across to the column headed by the number of grooves on the small
pulley and note the basic power rating. Multiply this figure by the belt length
correction factor (g) to obtain the actual power rating.
(k) Pulley Bores
From the pulley dimension tables, both pulleys are fitted with Taper Lock® Bushes
which will accommodate 55mm bores.
(j) Belt Width
The 38 groove pulley is flanged as standard.
Divide the Design Power found in step (c) by the actual power rating found in step
(h) to obtain the belt width factor. Using the table below the power ratings, select
a belt width which has a width factor equal to or greater than the figure found
above.
(k) Pulley Bores
Refer to the pulley dimensions (pages 98 to 100) and check that the Taper Lock®
Bush sizes in the pulleys selected can accommodate the shafts they are to fit.

ORDERING INSTRUCTIONS
If standard pulleys are to be used, (i.e. those combinations shown in the selection
tables) on the majority of drives it will be found that at least one pulley is flanged
as standard. If non-standard pulleys are to be used (i.e. combinations not shown
in the selection tables) one pulley requires to be flanged, and it is usually more
economical to flange the smaller one. If the centre distance exceeds 8 times the
outside diameter of the small pulley, or if shafts are vertical, both pulleys should
be flanged.
A complete drive usually consists of five components: two pulleys, two Taper Lock
bushes, and one belt.
(1)
Pulleys. The eight digit pulley code is given on the dimension
pages 96-103.
(2)
Taper Lock Bushes. The eight digit codes are given on the
Taper Lock Shaft Fixings pages 129-130
(3)
Belt. The belt code is given on page 93.

FENNER BELT TENSION INDICATOR
The high performance and efficiency of Fenner
Synchronous belts requires correct tension.
We recommend using the Fenner Belt Tension
Indicator.
NOTE: To measure tension in synchronous belts, place
a piece of rigid material across the belt width at midspan, before applying the gauge.

Installation Instructions - All Drives
Installation Instructions - All Drives
INSTALLATION TENSION
BELT INSTALLATION
Synchronous belt drives operate by positive meshing and do not require high
installed belt tensions.
Provision should be made for adjustment of the drive centre distance to allow
for installation of the belt around the pulleys without damage, and subsequent
pre-tensioning. A belt should never be forced over pulley flanges as internal belt
damage will result.
For optimum performance, however, belts should be installed with a pre-tension
suitable for the envisaged drive duty, derived from the formulae below.
Where a range is indicated, the lower value will be suitable for lightly loaded,
smooth running drives, whereas drives subject to high shock loads and/or
frequent starts should be tensioned to the higher level. Belt pre-tension is usually
achieved by drive centre distance extension and checked by applying a setting
force F (N) at mid belt span sufficient to deflect the belt a distance d (mm) related
to the length of the span S (metres).
It is necessary to ensure that the force is applied at right angles to the belt span,
and evenly across the belt width.
A Fenner Belt Tension Indicator may be used, in conjunction with a piece of rigid
bar laid across the face of the belt at mid-span
An electronic, sonic tension indicator is also available.
The following tables offer guidance as to the necessary adjustments for
installation and also for applying appropriate
pre-tension.

PULLEY ALIGNMENT
Misalignment of drive pulleys results in unequal tension across the belt width and
extreme edge wear. Pulley alignment should be proved using a straight-edge or
laser device, and shafts checked for parallelism.
Misalignment on any synchronous drive should not exceed 1/4O angular or 5mm/
metre centre distance parallel.
TORQUE DRIVE PLUS 3 & HTD DRIVES
(Deflection – d 20mm/metre span length - S)
Calculate the force F from the formulae below.
F (max) = kW x 955,000
F (min) = kW x 477,500 (N)
d.n
d.n
where
kW = Motor power, or absorbed power if known
d = Pitch diameter of either pulley (mm).
Drive support frameworks must be rigid to avoid flexure causing shaft
misalignment under drive forces.
Flexure can result in tooth jumping during high torque starts, particularly if
misalignment is present.
n = Rev/min of same pulley.
TIMING DRIVES
(Deflection – d 20 mm/metre span length - S)
Use force F from the table below.

NOTE: Excessive belt tension will reduce belt and bearing lives and may increase
drive noise levels. For fixed centre applications tension may be applied by an idler
pulley (see note on Idler Pulleys) or consult your local Authorised Distributor for
precise fixed centre dimensions. Drive support frameworks must be rigid to avoid
flexure resulting in centre distance reduction and consequent tooth jumping,
particularly on high torque starts.
BELT CARE
Avoid 'crimping' belts.
Folding belts such that they are tightly bent, e.g. for storage, damages the belt
cords and will lead to premature failure.
110
IDLER PULLEYS
Grooved idler pulleys can be used on the inside of all synchronous belts.
Flat (not crowned) idlers can be used on the outer surface of Classical Timing,
HTD and TDP3 belts.
Wherever possible, idlers should operate on the slack span of a belt, and arc of
contact should be kept to a minimum.
Idler pulleys should be of equal or greater diameter than the smaller of the drive
pulleys.
Spring loaded idler pulleys are not normally recommended.
TAPER LOCK
Most of the synchronous pulleys/sprockets featured in this section use Taper Lock
shaft fixing.
For detailed instructions on the fitting and dismounting of Taper Lock products see
Shaft Fixings page 129, or view the on-line video at www.fptgroup.com.
