Abstract

Different types of operational damages of bearings of the complex technical systems, being both a cause of failure and consequence of violation of operation conditions are considered. On example of bearings damaged under operation or at tests the reasons of loss of their working capacity are established. Methods of Scanning Electron Microscopy have been used for investigation of mechanisms of fatigue and static failure of parts from bearing steels. Defects of metallurgical origin in the central zones of damages of bearings have been investigated by method of X-ray Microanalysis. Microstructure of the damaged parts of bearings has been studied by method of optical microscopy and a nature of its change in case of thermal influence has been determined
