GENERAL TENSIONING OF V-BELT DRIVES
Tensioning of belts on a V-belt drive is usually not critical. A few simple rules about tensioning
will satisfy most of your requirements:
1. The best tension for the V-belt drive is
the lowest tension at which the belts will
not slip under the highest load condition.
2. Check the tension on a new drive
frequently during the first day of
operation.
3. Thereafter, check the drive tension
periodically.
4. Too much tension shortens belt and
bearing life.
5. Keep belts and sheaves free from any
foreign material that may cause slippage.
