Analysis of Electrical Spindle Bearing''''s High Speed Performance

According to the dynamic static analytical method established by Jones' raceway control theory,the contact and kinematic states between a ball and raceway are determined considering ball centrifugal forces and gyroscopic moments,and then the spin to roll ratio may be predicted.On the basis above,some of the important factors that affects bearing high speed performance and the ways to achieve the speed up are analyzed in detail.The conclusion obtained and the computer program are of great practical value to the development and application of high speed bearing.
