B-type belt size top width 17mm, 14mm high, angle of 40 degrees, pulley height shall not be less than 15mm.
Pulley, belonging to the disk hub type parts, general relative size is relatively large, the manufacturing process is generally based on casting, forging. Generally larger size is designed to use casting, the material is generally cast iron (casting performance is better), rarely with cast steel (steel casting performance is not good); generally smaller size, can be designed for forging, the material is steel.
The pulley is mainly used for long-distance transmission of power occasions, such as small diesel engine power output, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging beds, air compressors, speed reducers, reducers, generators, rolling mills and so on.
