11. Matching belts
Banded Torque Team® V-belts eliminate belt whip and turnover
problems experienced with multiple V-belt sets under certain
drive conditions. The individual ribs in the Torque Team® belts
are produced at the same time and bonded together. Thus,
ordering matched sets of individual V-belts is unnecessary.
Using more than one set of Torque Team® belts on the same
drive is possible. For example, 2/5V1250 and 3/5V1250
Torque Team® belts will transmit the same power as five
individual 5V1250 V-belts. The 2/5V1250 identification
describes a Torque Team® belt with two 5V1250 individual
V-belts joined together.
DO NOT mix belt brands.
DO NOT use sets from different manufacturers together as they
may have different performance characteristics.
DO NOT use new and used Torque Team® belts in combined
sets.
DO NOT use Torque Team Plus® belts in combined sets unless
they are matched by the factory.
12. How to install Torque Team® belts
Never force Torque Team® belts into a sheave. Instead,
decrease the center distance between the sheaves, allowing
the belt to slip easily into the sheave grooves.
To tension a newly-installed Torque Team® belt, increase the
center distance between the sheaves. Tables 8 and 9 (below
and page 20) detail center distance allowances for installation
and tensioning of Classical and HY-T® Wedge Torque Team®
belts. For example, a 5/5V1250 Torque Team® belt requires
decreasing the center distance 2.1 inches to install the belt and
increasing the center distance 1.8 inches to maintain sufficient
tension.
