Fault Diagnosis and Typical Failure Analysis of Rolling Mill Drive Shaft

针对国内某冷轧厂2130轧机传动轴事故,对目前广泛采用的十字轴式万向接轴及彭形齿式接轴的典型失效原因进行分析,提出了用振动、温度等物理量组成的故障特征参数进行监测的方法,改进轧机传动轴维护管理的一些措施,确保轧机安全运行。

According to the failure of the 2130 rolling mill drive shaft in a cold rolling mill,this paper analyzes the typical failure causes of the widely used cross axle type universal shaft and the drum type connecting shaft.The fault feature parameter with physical quantity and temperature of the monitoring method are put forward,some measures to improve maintenance of rolling mill drive shaft are made to ensure safe operation of rolling mill.
