PH Rubber V-Ribbed Belt for Automotive is also called multi-groove belt, and its foreign name is Multi wedge belt drive. It is an annular rubber transmission belt with a flat belt as the base body and an inner surface with longitudinal trapezoidal wedges arranged at 40° equal intervals. Its working surface is the side of the wedge. Poly-V belt has the comprehensive advantages of parallel transmission belt and combined V-belt. It has small bending stress and centrifugal stress loss and high transmission efficiency. It is suitable for multi-axis transmission, compact structure, high-power and high-speed systems such as automobile engines. Commonly used models are: PH, PJ, PK, PL, PM.
Advantages :
Poly-V belts combine the advantages of flat and V-belts. They have the softness and strength of flat belts and the compactness and efficiency of V-belts.
1. The contact area and friction between the multi-V belt and the pulley are larger, and the load is distributed more evenly along the bandwidth, so the transmission capacity is greater.
2. Because the belt body is thin and light, has good flexibility and has a reasonable structure, the working stress is small, and it is suitable for transmission with small diameter pulleys (smaller than traditional V-belt pulleys), and can also drive multiple wheels. Adapted to high-speed transmission, the belt speed can reach 40m/s with small vibration and heat generation
Less, smooth operation, heat-resistant, oil-resistant, wear-resistant, small elongation during use, and longer life.
