Special Industrial Belt Co., Ltd. processes and produces multi-ribbed belts, multi-ditch belts and multi-ribbed belt pulleys. The following gives you detailed knowledge of multi-ribbed belts and multi-ditch belts.
The V-ribbed belt is also called a multi-groove belt. It is a ring-shaped rubber transmission belt with a flat belt as the base and an inner surface arranged with a longitudinal 40° equidistant trapezoidal wedge. The working surface is the side of the wedge. The V-ribbed belt is especially suitable for high-speed transmissions with compact structure and high transmission power.

Introduction to the V-ribbed belt:
The V-ribbed belt is a ring-shaped rubber transmission belt with a flat belt as a base body and an inner surface arranged with a longitudinal 40° equidistant trapezoidal wedge, and the working surface is a side surface of the wedge. The V-ribbed belt is especially suitable for high-speed transmissions with compact structure and high transmission power. PH, PJ, PK, PL, PM model V-ribbed belt detailed introduction diagram
Advantages of the V-ribbed belt
The advantages of the V-ribbed belt combined with the plane and the V-belt are both the softness and toughness of the flat belt, and the compact and efficient V-belt.
1. The contact area and friction between the multi-ribbed belt and the pulley are large, and the distribution of the load along the bandwidth is relatively uniform, so the transmission capacity is greater.
2. Due to the thin and light body, good flexibility and reasonable structure, the working stress is small, and the transmission with small diameter of the pulley (less than the traditional V-belt pulley) can also drive multiple wheels. Adapt to high-speed transmission, belt speed up to 40m / s and vibration, heating
Less, smooth operation, heat resistance, oil resistance, wear resistance, small elongation and longer life.
3. The transmission power is large, the transmission efficiency is high, and the transmission power of the ordinary V-belt is 30% higher when the space is the same, and the energy-saving effect is obvious.
4, the drive is compact, in the case of the same transmission power, the transmission device takes up 25% less space than the ordinary V-belt.
5. The back of the V-ribbed belt can also be driven, and the automatic tension adjuster can be used to make the transmission safer and more reliable.
