Abstract
The article is devoted to the diagnostics of friction bearing of turbine generator and determination of the reasons of its destruction during exploitation. We have studied chemistry and mechanical properties of metal, have calculated strains acting on the shaft of turbine generator in the case of asymmetrical electric load. In the article we present the results of macrostructural and microstructural analysis with usage of modern technologies. According to the data diagnosis obtained, we conclude that the source of bearing destruction is babbit fatigue damage caused by asymmetrical electric load of generator. We recommend controlling the rate of bearing wear by monitoring of babbit components presence in oil and asymmetry of electric load to prevent similar destructions.
