摘　　要：某新能源汽车差速器半轴齿轮在台架试验后出现齿面剥落现象。通过齿轮宏观检查与分析、齿面电镜检测与分析等手段分析了轮齿齿面剥落原因。经磨削代替车削、增加喷丸处理等工艺优化措施,有效改善轮齿齿面质量,有效避免轮齿剥落失效问题的再次发生。After the bench test,the tooth surface of the differential axle gear of a new energy vehicle peeled off.The reasons for the spalling of the tooth surface of the gear teeth are analyzed by means of the macro inspection and analysis of the gear,and the detection and analysis of the tooth surface electron microscope.Through the process optimization measures such as grinding instead of turning and increasing shot peening,the quality of gear tooth surface can be effectively improved and the recurrence of gear tooth spalling failure can be effectively avoided.
