摘　　要：本文结合某型柴油机旋压式曲轴皮带轮NVH选型开发过程,简要梳理了发动机用皮带轮的历史演变及其机理,对两种常用曲轴皮带轮进行了关键NVH性能试验对比。试验证实匹配旋压式曲轴皮带轮的发动机可以达到相对可接受的NVH水平,实现某些机型的设计指标要求,可为主机厂皮带轮匹配设计提供部分技术参考。Combined with the NVH selection and development process of spinning crankshaft pulley of a certain diesel engine,the paper briefly combs the historical evolution and mechanism of engine pulley,and compares the key NVH performance tests of two kinds of commonly used crankshaft pulley.The test proves that the engine matching the spinning crankshaft pulley can reach the relatively acceptable NVH level,and realize the design index requirements of some models,which can provide some technical reference for the belt pulley matching design of the main engine factory.
