Diagnostics of the Technical Condition of Rolling Bearings of Asynchronous Traction Motors of Locomotives Based on Data Mining

The failures of rolling bearings of asynchronous traction motors of locomotives are studied. The malfunctions of rolling bearing units of locomotives are analyzed. The vibration and current signals and the corresponding frequency spectra of an electric motor when operating in normal conditions, as well as with bearing failures, are presented. A model to assess the technical condition of locomotive rolling bearings is developed, and the feasibility of proactive diagnosis, which makes it possible to identify defects in advance at an early stage of their development, is substantiated. The results of the study can be used in systems of real-time diagnosis of the technical condition of rolling bearings of asynchronous traction motors of locomotives.
