Abstract: Gear and bearing equipment of coal mine machinery plays an important role in the production process of coal mines.
Based on the analysis of fault types and causes of mechanical gears and bearings, this paper pointed out that vibration signal
detection method is the main method to diagnose gear and bearing faults of coal mine machinery, and expounded the process of the
diagnosis method in detail. At the same time, according to the fault types and failure modes, it put forward the improvement
measures of gear and bearing faults, which has important reference value for reducing the failure rate of gears and bearings of coal
mine machinery and increasing the service life of equipment.

Key words: gear; bearing; fault diagnosis; improvement measures
