基于滚动轴承动力学和有限元热分析理论建立了摩擦功耗和热传递模型，利用 ANSYS Workbench 稳态热分析模块研究了不同工况下轴承组件的温度分布及变化规律。结果表明：轴承组件的最高温度发生在钢球与内沟道的接触处；轴承组件温度随转速、轴向载荷、环境温度和电动机功率的增加而升高；径向载荷对系统温升亦有影响，但相对不明显。
基于滾動軸承動力學和有限元熱分析理論建立瞭摩抆功耗和熱傳遞模型，利用 ANSYS Workbench 穩態熱分析模塊研究瞭不同工況下軸承組件的溫度分佈及變化規律。結果錶明：軸承組件的最高溫度髮生在鋼毬與內溝道的接觸處；軸承組件溫度隨轉速、軸嚮載荷、環境溫度和電動機功率的增加而升高；徑嚮載荷對繫統溫升亦有影響，但相對不明顯。

The models for frictional power consumption and heat transmission are established based on theory of dynam-ics of rolling bearings and finite element thermal analysis,the temperature distributions and variation law of bearing as-sembly under different operating conditions are studied by using ANSYS Workbench ANSYS Workbench steady state thermal analysis module.The results show that the highest temperature of bearing assembly is located at contact area of steel ball and inner raceway,the temperature of bearing assembly is increased with the increase of rotating speed,axial load,ambient temperature and motor power,and the radial load has no significant effect on system temperature rise.
