Ribbed Belt Pulley

Ribbed Belt pulley is a pulley used for transmission machinery. Because it uses multiple wedge belts, multi-ribbed Belt Pulley has better transmission efficiency and driving force than ordinary pulleys. The basic structure of ribbed belt pulley includes a wheel disc and a wedge-shaped belt, the working surface of this multi-ribbed belt pulley is the side of the wedge.
The transmission efficiency of ribbed belt pulley is very high, and its transmission efficiency can reach up to about 98%. And it also has certain buffering and shock-absorbing capabilities while maintaining a smooth transmission speed.
Suitable for transmissions that need to withstand high power and high torque, such as:
1. Automobile: multi-ribbed belt pulley can be used in the transmission system of automobile engines to improve the performance and economy of the vehicle.
2. Engineering machinery: multi-ribbed belt pulley can be used in the transmission system of engineering machinery to improve the working efficiency and reliability of the machinery.
3. Ships: multi-ribbed belt pulley can be used in the transmission system of ships to improve the performance and safety of the entire system of the ship.
