【Abstract】 In order to improve the thermal properties of h ig h-speed spindle unit,the force imposed on the angular contact ball bearing was a nalyzed,the contact load between balls and races and the heat generated by beari ng’s friction were calculated.Then,a computer program to calculate the bearing’s heat was developed.A practical bearing’ s heat was calculated to validate the program.In the end,the bearing’ s main parameters that influence the generated heat were discussed.更多还原
