Multi-wedge belt introduction:
Multi-wedge belt is also called multi-groove belt, foreign name Multi wedge belt drive, is a flat belt as the matrix, the inner surface is arranged with longitudinal 40° equal spacing trapezoidal wedge ring rubber belt, the working face is the side of the wedge. The multi-wedge belt has the comprehensive advantages of parallel transmission belt and joint V-belt. Low bending stress and centrifugal stress loss, high transmission efficiency, suitable for multi-axis transmission such as automobile engine, compact structure, high power and high speed system. Commonly used models are: PH, PJ, PK, PL, PM.

Multi-wedge belt detailed introduction
Note: 1. The values of wedge distance and band height are only reference dimensions, and the cumulative wedge distance error is an important parameter, but it is affected by the working tension of the band and the elastic modulus of the tensile body.
2. The unit of this table is mm
