The timing belt is an endless belt with steel wire rope or glass fiber as the strong layer and covered with polyurethane or neoprene rubber. When the synchronous belt is driven, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, the oil resistance, the wear resistance and the aging resistance are good. i<10, it can also be used for low-speed transmission for transmissions requiring synchronization.

The timing belt drive is composed of an endless belt with equidistant teeth on the inner peripheral surface and a corresponding wheel.

It combines the advantages of belt drive, chain drive and gear drive. When rotating, the power is transmitted through the meshing of the belt teeth with the tooth slots of the wheel. The synchronous belt drive for transmission has an accurate transmission ratio, no slip, a constant speed ratio, stable transmission, vibration absorption, low noise, and a large transmission ratio range, generally up to 1:10.

The allowable line speed can reach 50M/S, and the transmission power ranges from a few watts to a hundred kilowatts. High transmission efficiency, generally up to 98%, compact structure, suitable for multi-axis transmission, no lubrication, no pollution, so it can work normally in places where pollution is not allowed and the working environment is relatively harsh.

Transmission products are widely used in various types of mechanical transmissions in various industries such as textiles, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instrumentation, food, mining, petroleum, automobiles and other industries.
