Crossed Belt Friction Belt Drive Calculator. Where: L = Length (inches) C = Center Distance (inches) D 1 = Pitch Diameter of Small Pulley (inches) D2 = Pitch Diameter of Large Pulley (inches) When determining the length of a serrated type belt, both equations are to be divided by the belt serration pitch. The serrated belt length should be designed for whole or even number of serrations.

The belt also tends to wedge into the groove as the load increases—the greater the load, the greater the wedging action—improving torque transmission and making the V-belt an effective solution, needing less width and tension than flat belts. V-belts trump flat belts with their small center distances and high reduction ratios. The preferred center distance is larger than the largest pulley ...

Get Price### How crowned pulleys keep a flat belt tracking

These flat belts stayed centered on pulleys without any guides or flanges. The key to keeping them tracking centered on the pulleys is the use of "crowned pulleys". A crowned pulley is a pulley that has a slight hump in the middle, tapering off ever so slightly towards either edge. How a crowned pulley keeps the belt tracking on it is a mystery to most people, so I thought I'd write a small ...

SECTION 22 CENTER DISTANCE FORMULAS ... 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. Synchronous belts ...
