Description

Technical Field

[0001] The utility model relates to the technical field of pulley equipment, in particular to a pulley with an anti-slip function. Background Art

[0002] A pulley is a mechanical part used for transmission, usually made of metal or plastic, with a raised rim or groove for matching with a belt. The pulley is usually mounted on a shaft and connected to a power source through the shaft to transmit power and motion. The pulley and the belt transmit power through friction or the cooperation of teeth and grooves, thereby driving other mechanical parts or equipment to operate.

[0003] The pulleys currently on the market are prone to slipping during long-term use. Slipping will cause incomplete energy transfer between the belt and the wheel, resulting in a decrease in transmission efficiency and thus energy loss. At the same time, slipping will cause the stability of the transmission system to decrease, which may cause unstable equipment operation and even sudden stagnation or stalling, affecting production efficiency and equipment safety. Therefore, a pulley with an anti-slip function is proposed to solve the above problems. Utility Model Content
