摘　　要：对某电动商用车减速器在台架测试过程中出现的异常现象进行研究,对减速器进行拆解分析,从齿轮旋向设计、轴承孔设计、轴承润滑方式设计、轴承的安装定位以及轴承的型式选择几个方面,解决轴承失效的问题,最终通过耐久台架测试,使得减速器满足寿命要求。The abnormal phenomenon of an electric commercial vehicle retarder during bench test was studied. The reducer was disassembled to analyze. From the points of the rotation design of gears,the bearing hole design,the bearing lubrication mode design,the fixing orientation of bearing and the type of bearing,the failure problem of bearing was resovled. Finally,the durability test of the retarder is passed,it can meet the life requirement.
