motorcycle back support belt

An endless flat drive belt is a continuous loop made from flexible materials, designed to transmit power between pulleys located at varying distances. Unlike traditional belts that often feature a textured surface or teeth for grip, flat belts rely on friction between the belt surface and the pulleys to facilitate movement. The endless feature indicates that the belt has no joints or seams, reducing the risk of wear and breakdown while ensuring a smooth operation.

The most common material used in timing belts is various types of rubber. Synthetic rubber, such as neoprene, is often preferred due to its superior resistance to heat and wear compared to natural rubber. The rubber provides flexibility, allowing the belt to bend around pulleys without cracking. This elasticity also contributes to a quiet operation, reducing engine noise. However, rubber's susceptibility to degradation from oil, heat, and ozone exposure necessitates the incorporation of additives and reinforcements.
