Standard stock products offer the best value for most
power transmission operations. But, for requirements that
cannot be served with stock products, DODGE manufac­
tures custom-made sheaves and synchronous belt

V-Drives
V-Belts
V-drives have been the mainstay of industrial power transmission for over
60 years. During this time, DODGE has been a major influence, designing
and developing innovative concepts in V-belt sheaves and supplying the
highest qual­ity belts.
Today’s V-drives offer quiet, efficient mechanical power transmission.
They pro­vide many thousands of hours of performance, even under

conditions of shock load and normal drive misalignment. All of these
benefits come at an economic value that is unsurpassed.

POLYBAND banded V-belts are engineered to handle those problem drives where
vibration, sudden shock loads or misalignment causes belts to turn over, whip or
jump off sheave. Two or more belts are inseparable joined together as one single unit. HT500

FLEXLINK BELT APPLICATION GUIDELINES

DYNA-SYNC

1. To obtain link belt length, multiply desired pitch length by .916. This provides correct belt length for initial run-in and
seating of belt.
2. For matched sets of link belts, use the same number of links on each belt.
3. Do not use link belting above 5000 FPM belt speed.
Belt speed = .262 x RPM x pitch diameter of sheave.
4. Note: Link belting is not static conducting.
Important -
Synchronous Drives

For matched sets of link belts use same number of links on each belt.
HT200/HTD

• Fast installation, installs in a snap

• Adjustable to any length, adaptable to any drive
• Reduces vibration
Synchronous Drives

• Long-lasting construction
• Reduces inventory - one reel can replace many sizes of standard belting
HT500

• Oil proof construction

• Order by the foot or by the reel.

For any given set of drive conditions, there are many differ­ent
drives that will satisfy the requirements. What is a “best drive”?
It could be the drive with lowest initial cost, or the drive with the
lowest bearing load, or the drive which mini­mizes the number of
parts required.
Finding the best drive is a time-consuming and frustrating
task for the design engineer. Manual drive selection, pric­ing,

TENSIONING A DRIVE
General Rules of Tensioning–
1. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions.
2. Check tension frequently during the first 24-48 hours of run-in operation.
3. Over tensioning shortens belt and bearing life.
DYNA-SYNC

4. Keep belts free from foreign material which may cause slip.
5. Make V-Drive inspection on a periodic basis. Tension when slipping. Never apply belt dressing
as this will damage the belt and cause early failure.
Synchronous Drives

3. Compare the force you have applied with the values

given in Tables 13 or 14. If the force is between the values

the 1/64, for every inch of span length. For example, one
deflection of a 100 inch span would be 100/64 or 1-9/16
inches. For V-Belt Tension Testers, See Page PT7-142.
Synchronous Drives

After the proper operating tension has been applied to the

belts, a double-check should be made of the following:

a. Parallel position of the sheave shafts.

b. Correct alignment of sheave grooves.
