Method for Calculating the Parameters of Shock Pulses in Bearings with Local Damages to Raceways

Abstract

The method proposed in the article for calculating the parameters of shock pulses generated in rolling bearings when local defects occur is a development of research in the scientific direction of vibration-pulse diagnostics in relation to the operational assessment of the technical condition of rolling bearings of transmission units of mobile vehicles operating under variable load-speed conditions. An example of calculating the parameters of the shock pulse in ball radial single-row bearings of the 307 series is given, when the rolling body passes through a rectangular defect on the outer raceway.
