The synchronous belt drive consists of an annular belt with equidistant teeth on the inner circumferential surface and a corresponding wheel. It combines the advantages of belt drive, chain drive and gear drive. When rotating, power is transmitted by meshing the belt teeth with the cogging groove of the wheel. The Transmission Dragon Timing Belt drive has accurate gear ratio, no slippage and constant gear ratio. Stable transmission, vibration damping, low noise, large transmission ratio range, usually up to 1:10. The permissible line speed can reach 50M / s, and the transmission power can be from a few watts to a hundred kilowatts. High transmission efficiency, generally up to 98%, compact structure, suitable for multi-shaft transmission, no lubrication, no pollution, so it can work normally in places where pollution is not allowed and the working environment is bad. Transmission products are widely used in various mechanical transmissions in various industries such as textile, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instrumentation, food, mining, petroleum and automobile.

2. Features of timing belt
