The timing belt is a wire rope or glass fiber as a strong layer, covered with polyurethane or neoprene outer annular band, dentate made ​​from the inner periphery of the belt so that it meshes with the toothed pulley.
Belt drive transmission ratio is accurate, the axial force small, compact, oil resistance, abrasion resistance, anti-aging properties, the general temperature of -20 ° C to -80 ° C,
Require synchronization transmission is also available in the low-speed transmission.
Belt drive is composed of an inner surface with pitch toothed endless belt and the corresponding fit round the composition. It combines a belt drive, chain drive and gear drive their own advantages. Rotated, is engaged to transmit power through the toothed wheel cogging. Transmission with belt drive the accurate transmission ratio, non-slip, constant speed ratio can be obtained, smooth transmission, absorbing vibration, noise, transmission ratio range, generally up to 1:10. Allow line speeds of up to 50M / S transfer power from a few watts to one hundred kilowatts. High transmission efficiency, generally up to 98%, compact structure, suitable for multi-axis drive, no lubrication, no pollution, it can work normally not allowed pollution and working environment more hostile place. Transmission products are widely used in textiles, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instrumentation, food, mining, petroleum, automotive and other industries for various types of mechanical transmission.
