Timing Belts - High-strength Elastomer With Glass Fiber Reinforcement | Synchronous Drive, Trapezoidal Tooth Profile, Power Transmission Up To 150 Kw

Our range of Timing Belts are basically endless flat belts which pass over pulleys- the belts having grooves which mate with teeth on the pulleys. These belt drives, unlike flat and vee belt drives are positive. Any slip of the belt relative to the pulleys is minor in degree and is due to belt stretch, or erosion of the grooves. These belts are used for power transfer and for synchronised drives to ensure that the driven pulley is always rotating at a fixed speed ratio to the driving pulley.

The first synchronous belts had a trapezoidal tooth profile, and is identified as timing belts. The belt tooth profile is a trapezoidal shape with sides being straight lines The profile of the pulley teeth which mates with the belt is involute. These belts are based on imperial (inch) pitch sizes and can provide power transmission up to 150 kW.

Timing belts are made with elastomer e.g natural rubber,neoprene, polyurethane, polychioroprene, core with reinforcement to provide increased tensile strength. These belts were originally reinforced with steel to provide the necessary strength. In modern drives the most common reinforcement is glass fiber, but aramid is used if maximum capacity is required. Synchronous belts are often provided with nylon facings to provide the necessary wear resistance and can include conductive coatings.
