| 为探究角接触球轴承的生热和机械性能对其工作精度和使用寿命的影响，课题组基于Palmgren摩擦生热理论，建立了轴承热 结构耦合模型；利用ANSYS Workbench有限元仿真软件分析了不同转速和载荷对轴承温升的影响，求解出轴承零件的温度分布；将仿真结果与实验结果的变化趋势进行比较，验证理论模型的正确性，最后得到轴承的热特性规律。结果表明：随着内圈转速的加快和轴向载荷的增大，各部件的温度都会升高，其中滚珠的温度升高幅度最大；且转速对生热量和温升的影响更显著。该研究结果可为轴承结构的热优化设计提供参考。 |

| In order to investigate the influence of heat generation and mechanical properties of angular contact ball bearings on their working accuracy and service life，a coupling model of bearing thermal structure was established based on Palmgren friction heat generation theory. The influence of different rotational speeds and loads on bearing temperature rise were analyzed by ANSYS Workbench final element simulation software, and the temperature distribution of bearing parts was solved. The variation trend of the simulation results and the experimental results were compared to verify the correctness of the theoretical model, and finally the thermal characteristics of the bearing were obtained. The results show that as the speed of the inner ring increases and the axial load increases, the temperature of each component increases, with the ball bearing having the largest temperature increase, and the influence of speed on heat generation and temperature rise is more significant. The results can provide reference for the thermal optimization design of bearing structure. |
