第四讲电机组装后轴承状态检查轴承出现初期故障,如不及时处理会迅速扩大造成严重后果,影响行车安全。当产生严重烧损等故障后,就很难再确定故障的原因。而原因找不到,即使换上一个新的轴承,仍可能以同样的方式损坏。轴承损坏的同时往往引起轴承密封圈、轴承座等严重损坏。更换或修理上述部件所费的代价会远远大于及时检查采 Lecture 4 after the motor assembly bearing inspection bearing initial failure, if not promptly dealt with the rapid expansion of the serious consequences, affecting traffic safety. When a serious burn and other failures, it is difficult to determine the cause of the malfunction. The reason can not find, even with a new bearing, may still be damaged in the same way. At the same time bearing damage often caused by bearing seals, bearing housings and other serious damage.
