FLAT WIRE CONVEYOR BELT TECHNICAL MANUAL

Flat wire conveyor belts can be driven by either a sprocket system or a pulley system SPROCKET DRIVEN CONFIGURATIONS Sprocket driven systems provide a positive drive of the belt that prevents slippage between the belt and the sprockets and results in less power loss The sprocket teeth also help maintain belt alignment.

Belt Theory

For a flat belt drive the friction between the belt and pulley for a small segment of belt is =µ 𝑅 while for a V belt/sheave with a 38° angle the friction would be =2.92 µ 𝑅 o The same hub load and stress in the tensile members gives V belts nearly 3x the friction of flat belts.
