摘　　要：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。The models for frictional power consumption and heat transmission are established based on theory of dynamics of rolling bearings and finite element thermal analysis,the temperature distributions and variation law of bearing assembly 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.
