The timing belt drive is composed of a closed annular tape with equal-spaced teeth on the inner peripheral surface and a corresponding pulley.In operation, toothed slots with teeth engage, It is a meshing drive,Thus has the respective advantages of gear transmission, chain transmission and belt transmission.Transmission is accurate, stable, and low noise,and can get constant speed ratio, and the speed ratio range is big. Permissible linear speed, compact drive structure, suit to be multi-axis transmission.At the same time, the timing belt also has excellent anti-bump performance, low elongation, high strength, etc.and oil resistance, heat resistance, aging resistance, ozone resistance, crack resistance and other excellent performance
