The PK belt is an annular rubber belt with flat belt as the matrix and an inner surface arranged with 40° longitudinal-equidistance trapezoidal wedge, and its working face is the side of the wedge. Multi – wedge belt is especially suitable for compact structure, high – speed transmission power.
The advantages of PK belt combined with the advantages of plane and V belt, both smooth surface with soft, strong characteristics, and V belt compact, efficient and other advantages.
1.Ribbed belt and the belt wheel contact area and friction is larger, the load along the bandwidth distribution is more uniform, so the transmission capacity is greater.
2, because the belt body is thin and light, flexible, reasonable structure, so the working stress is small, suitable for small diameter of the belt pulley transmission (less than the traditional triangle belt pulley), can also drive multiple wheels. Adapt to high speed transmission, belt speed up to 40m/s and small vibration, less heating, stable operation, heat resistance, oil resistance, wear resistance, small elongation, longer life.
3, transmission power, high transmission efficiency, the same space than ordinary V-belt transmission power 30% higher, energy-saving effect is obvious.
4, the transmission is compact, in the same transmission power, the transmission device takes up 25% less space than the ordinary ploy V-belt.
