Based on the quasi static model of ball bearings, the variation of oil viscosity, heat source and bearing structure size with temperature are considered, and then a high-speed ball bearing thermal calculation model is established. The transient thermal characteristics of high-speed ball bearings are obtained by calculating thermal equilibrium equations. Then, effects of different parameters on the heat generation, temperature and thermally-induced load of ball bearings are studied, which may provide a theoretical basis for the selection of lubrication parameters, structure optimization, thermal failure mechanism and failure analysis of high-speed ball bearings. The results show: inner ring speed and axial load have obvious influence on the thermal equilibrium temperature and thermally–induced load; the thermally–induced load can be decreased by using lower viscosity oil and increasing the convection coefficient of air; the predicted theoretical results are also in good agreement with the experimental results.
