pulley
Belt pulley is a kind of disc hub part with relatively large relative size, and its manufacturing process is mainly casting and forging. Generally, the larger size is designed by casting method, and the material is generally cast iron (with good casting performance), but rarely cast steel (with poor casting performance); Generally, the smaller size can be designed as forging, and the material is steel. Belt pulleys are mainly used for long-distance transmission of power, such as the output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging beds, transmission of power of some small horsepower motorcycles, transmission of power of agricultural machinery, air compressors, reducers, reducers, generators, ginning machines, etc.
