Thermal behavior study and experimental testing of deep groove ball bearings.

In this study, based on the experimental analysis of heat generation in deep groove ball bearings, the thermal nodes about the deep groove ball bearings is established by using heat network method. The temperature field of the bearing is simulated with finite element software, and the result obtained from the simulation is in good agreement with the comparison of the theoretical calculation results. The bearing test bench was used to analyze the bearing, and the experimental results again proved the effectiveness of the thermal network method. It was found that the bearing speed played a significant role in the working temperature of a bearing, which was consistent to the analysis of the thermal network method, verifying the feasibility of the thermal network method to solve bearing temperature, laying the foundation for the subsequent research on the heat transfer law of motor and rolling bearing.
