- Abstract
The friction inside the angular contact ball bearings for high speed motorized spindle will increase the bearing temperature, which will affect the performances of the spindle. In order to analyze the temperature field of high speed angular contact ball bearings accurately, an analysis method is proposed considering the interaction between thermally induced load and friction heat generation. Firstly, the calculation model of total friction heat generation considering the friction caused by differential sliding, spin sliding, load, lubricating oil viscosity, and the calculation model of thermally induced load are established; then the interaction between the two is analyzed; finally, the steady-state temperature field of the bearings is obtained based on finite element analysis software. The results show that: in a steady state, the highest temperature of the bearings is in the contact area between ball and inner ring, and the temperature in the contact area between ball and outer ring is lower; when the thermally induced load is considered, the friction heat generation caused by differential sliding, spin sliding and load is larger than that without considering the thermally induced load, and the friction heat generation caused by lubricating oil viscosity has no change; the contact force between ball and inner ring and the temperature rise considering the thermally induced load are larger than those without considering the thermally induced load.
