How to find the maximum tension on a belt in a belt drive ...

Calculate the drive tension per width of belt by taking the Td figure found in step 1 and dividing by the belt width. 3. If using a belt at an elevated temperature, ply the maximum allowable tension per foot of width (given in the conveyor specification tables) by a factor from the table below to get the working tension at an elevated temperature.

The best tension for a V-belt is the lowest tension at which the belts will not slip under full load. Other belt tension recommendations are: Check the belt tension frequently during the first 24 to 48 hours of run-in operation. Maintain sheave alignment while tensioning the drive. Make V-belt drive inspections periodically checking belt tension.

To tension a V-belt, apply the lowest amount of tension that prevents the belt from slipping under full load. For a synchronous belt, you must properly seat the belt in the sprocket. To ensure proper tension, either type of belt should be "run-in." This process consists of running the drive under full load, then stopping, checking the tension,

THE WORLD OF TIMING BELTS - Lasersaur

Timing belts are basically flat belts with a series of evenly spaced teeth on the inside circumference, thereby combining the advantages of the flat belt with the positive grip features of chains and gears. There is no slippage or creep as with plain flat belts. Required belt tension is low, therefore producing very small bearing loads.
