The heat generation mechanism of angular contact ball bearing are analyzed. The heat generation rate and ball temperature of angular contact ball bearing are calculated with respect to the various shaft speed, load and lubrication method. The analysis is focused mainly on the predominant sources of heat generation which are spin-moment, gyro-moment, torque due to applied load and viscous friction torque. The viscosity of lubricant is assumed to be a function of the temperature only and the contact between ball and race is assumed to be elastic. Lumped capacitance method is adopted to compute ball temperature. Effective load is calculated iteratively considering the rate of ball expansion due to the temperature rise.
