Simulation and Experimental of Thermal Performance of Angular Contact Ball Bearings
Based on the experiment of heat generation of angular contact ball bearing 7005C,the thermal node of angular contact ball bearing was established by thermal network method.The temperature field of bearing was simulated by finite element software,and the simulation results were in good agreement with the theoretical calculation results.The bearing was tested by the test bench,and the experimental results proved the effectiveness of the thermal network method.It is found that the bearing speed has a significant effect on the operating temperature of the bearing,which is consistent with the analysis results of the thermal network method,the feasibility of the thermal network method is verified to solve the bearing temperature,and lays a foundation for the subsequent study of the heat transfer law of the motor and rolling bearing.
