Abstract: A new method of is put forward for predicting accurately the temperature rise of high-speed angular contact ball bearing considering the interaction between contact parameters and frictional heat generation under the actual working state in this paper. The contact parameters, of which the loaded angular contact ball bearings are read from the extracted code in real time using the Python script independently compiled with Abaqus software, is the initial variables to calculate the bearing friction heat generation. It is used as a time-varying thermal loads to the finite element model for solving the temperature rise of high-speed angular contact ball bearings under the radial load and rotation speed. Finally, the interactions of the contact parameters, frictional heat generation, and temperature rise can be received. The result shows that the method of predicting the temperature rise of high-speed angular contact ball bearings under the interaction of contact parameters and frictional heat generation is more in line with the actual working conditions.
