皮带轮属于集线器类型的零件，通常尺寸相对较大，制造过程通常基于铸造和锻造.通常，通常通过铸造方法设计较大的尺寸，并且该材料通常是铸铁（良好的铸造性能），并且铸造钢很少使用（钢制铸造性能较差）； generally smaller size can be designed as forging, and the material is steel. Pulleys are mainly used for long-distance transmission of power, such as small diesel engine power output, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, power transmission of some small horsepower motorcycles, power transmission of agricultural机械，空气压缩机，还原器，还原器，发电机，棉花套等.
