Exotherm invalidation analysis and experimental study on high speed grease lubricated bearing

The study on exotherm invalidation of high speed grease lubricated bearing has been carried out from two aspects of theory and experiment by means of living example analysis.Theoretical calculation on the calorific capacity of bearing was carried through and the main factor that influences the calorific capacity of bearing was determined.The reasons of exotherm invalidation have been found out thus solved the exotherm failure of high speed grease lubricated bearings.
