摘　　要：针对配属HXD2型电力机车牵引电机例行试验振动值超标问题,根据电机结构和统计的振动值数据,从电磁和机械两方面对电机振动值超标问题进行原因分析,排除电磁和转子动平衡两个因素,通过测量定子止口尺寸、查看现场操作人员装配电机过程、检查定子止口端面清洁度,找出振动值超标的原因,最后从调整机座加工工艺流程、细化轴承座装配方法、提高配件清洁度三个方面进行工艺提升,降低电机返工率,提高电机装配质量和试验一次合格率,保证机车在线正常运行。Aiming at the problem of excessive vibration value in routine test of traction motor of HXD2 electric locomotive,according to the structure and statistical vibration value data of the motor,the causes of excessive vibration value of the motor are analyzed from both electromagnetic and mechanical aspects,and the two factors of electromagnetic and rotor dynamic balance were eliminated.The causes of excessive vibration value were found by measuring the size of the stator lip.checking the on-site operator's assembly process of the motor,and checking the cleanliness of the end face of the stator lip.Finally,the process improvement was carried out from three aspects:adjusting the machining process flow of the base,refining the assembly method of the bearing base,and improving the cleanliness of the parts,so as to reduce the rework rate of the motor,improve the assembly quality of the motor and the first pass rate of the test,and ensure the normal operation of the locomotive online.
