V-Belt
INSTALLATION GUIDE
Tensioning Methods
When you install belts at optimal tension, you save time and
money. To illustrate this point, this table compares the cost and
accuracy of various V-belt tensioning methods.
Choose one of three tensioning methods for V-belts:
TensionRite®
Two TensionRite® gauges are available: one for single belt drives
and another for banded belt drives.
For more detailed instructions for using TensionRite,® refer to the
instructions attached to gauge.
TENSION
Proper tension is essential for maximum belt life and effciency.
Improper belt tension is the primary cause of premature
belt failure and increased costs. Under-tensioned belts lead to
slippage, overheating, rollover and noise, all of which lead to
higher maintenance costs and ineffcient transmission of power.
Also, over-tensioning belts leads to premature wear, along with
bearing, shaft and sheave problems. The result is more frequent
replacement of drive components and costly downtime.
Common Sense Rules of V–Belt Tensioning
The ideal tension is the lowest tension at which the belt will not slip
under peak load conditions.
Check the belt tension frequently during the frst 24-48 hours of
run-in operation.
Do not over-tension belts. Doing so will shorten belt and bearing life.
Keep belts free from foreign materials that may cause slippage.
Inspect the V-drive periodically. Re-tension the belts if they
are slipping.
Maintain sheave alignment with a strong straight-edge tool while
tensioning V-belts.
