Fault Diagnosis of the Bearing with Low Speed and High Load

As the core component of large-scale machine, the performance of low speed high load bearings directly affect the operation of the machine, the fault diagnosis methods of the bearings has been a hot issue. By list different types of fault problems, at the same time, there are many methods of such bearings in recent years, the classification and comparative analysis of fault diagnosis method in the paper, and finally make a summary and outlook.
