Multi-wedge belt refers to the ring-shaped rubber belt with flat belt as the matrix and equal spacing longitudinal 40 degree trapezoidal wedge arranged on the inner surface. Its working face is the side of the wedge.

The advantages of the multi-wedge belt are as follows. The contact area and friction force between the multi-wedge belt and the pulley are larger, and the load distribution along the bandwidth is more uniform, so the transmission capacity is larger. Because the belt body is thin and light, flexible and reasonable structure, the working stress is small, and it can work on the smaller pulley. The multi-wedge belt also has the advantages of small transmission vibration, rapid heat dissipation and transportation. It has the characteristics of stable rotation, small use elongation, large transmission ratio and high limit linear speed, so it has longer service life, obvious energy-saving effect, high transmission efficiency, compact transmission and small space occupation. In addition, the back of the multi-wedge belt can also drive and use of automatic tension regulator, so that the transmission is more safe and reliable. The multi wedge belt is especially suitable for high speed transmission with compact structure and high transmission power.

The main features are as follows.

1. The transmission power is large, and the transmission power is 30% higher than that of the ordinary V belt when the space is same.

2. The structure of transmission system is compact. Under the same transmission power, the space of transmission device is 25% smaller than that of ordinary V-belt.

3. The belt body is thin, flexible, suitable for transmission with small pulley diameter (smaller than the traditional triangular belt pulley), and can also drive multiple wheels. It is suitable for high speed transmission, with speed up to 40m/s, small vibration, less heat and smooth operation.

4. Heat resistance, oil resistance, wear resistance, small elongation and long service life.
