OPTIONS FOR SOLVING GENESIS PROBLEMS IN THE EVENT OF VIOLATION OF THE LUBRICATION MODE OF ELECTRIC MOTOR BEARINGS
(pp. 34-44)

Abstract. Visual inspection of the nature of damage to the bearings of a failed engine is the final stage of diagnostics, allowing to determine the true cause. Examples of solving the problems of the genesis of failures of asynchronous electric motors associated with a violation of the lubrication mode of rolling and sliding bearings are considered. Determining the cause of the damage that has occurred allows you to prevent and eliminate the occurrence of repeated failures, increase the stability of a complex of complex technological equipment of industrial enterprises. Data from a practical analysis of the occurrence of failure of bearing units of asynchronous motors and recommended measures to prevent the occurrence of such failures in the future are given. It is proposed to link the direction of further research with the development of operational methods for determining the main characteristics of plastic lubricants for small volumes.

Keywords: electric motor, cause of failure, bearings, lubricant, visual inspection.
