Multi-Groove Belt(Multi-belt, multi-wedge belt) refers to the flat belt as the matrix, the inner surface is arranged with equal spacing longitudinal 40° trapezoidal wedge Ring Rubber Belt, its face for the wedge side.

The advantage of the multi-wedge belt is that the contact area and friction force of the multi wedge Belt and pulley are larger, and the distribution of the load along the bandwidth is more uniform. Therefore, the transmission capacity is larger, because of the thin and light, flexible, reasonable structure, so the work stress is small, can work on the smaller pulley; multi-wedge belt also has small transmission vibration, fast heat dissipation, smooth operation, the use of small elongation, The ratio is large and the limit line speed is high, thus the life is longer; the energy-saving effect is obvious, the transmission efficiency is high, the transmission is compact, and the space is small. In addition, the back of the ribbed belt can also drive, and can use the automatic tension regulator, so that the transmission more secure and reliable. Multi-wedge belt is especially suitable for high speed transmission with compact structure and

The main features are as follows: 1. Large transmission power, the same space than the normal V-belt transmission power of high 30%.2. The transmission system is compact in structure, and the transfer device occupies less space than the ordinary V-belt 25%.3 under the same transmission power. With body thin, full of softness, suitable for belt wheel diameter small transmission, also adapt to high-speed transmission, with speed can reach 40m/s, vibration small, less heat, smooth operation. 4. Heat-resisting, oil-resistant, wear-resistant, with small elongation and long life.

Multi-wedge Belt and antisymmetric groove belt, mainly used in engine, motor and other power equipment transmission. The current market types are: PH, PJ, PK, PL, PM
