Bearing load analysis and control of a motorized high speed spindle
International Journal of Machine Tools and Manufacture, 2005Angular contact ball bearings are the most popular bearing type used in the high speed spindle for machining centers. Because the bearing load is increased rapidly with the raised spindle speed due to the centrifugal force and temperature raise, proper initial preload and especially operating-induced load control of the angular ball bearing is ...
