摘　　要：高速电主轴角接触球轴承内部的摩擦会使轴承温度升高,进而影响主轴的使用性能。为精确分析高速角接触球轴承的温度场,提出了一种考虑热诱导载荷和摩擦生热交互影响的轴承温度场分析方法。首先建立考虑差动滑动、自旋滑动、载荷以及润滑油黏性引起的摩擦的总摩擦生热量计算模型和热诱导载荷计算模型,然后分析两者之间的交互影响,最终基于有限元分析软件得到轴承稳态温度场,结果表明:稳态时轴承最高温度在球与内圈接触区域,球与外圈的接触区域温度较低;考虑热诱导载荷时差动滑动、自旋滑动以及载荷引起的摩擦生热量大于未考虑热诱导载荷,润滑油黏性引起的摩擦生热量无变化;考虑热诱导载荷时球与内圈的接触力及温升大于未考虑热诱导载荷。The friction inside the angular contact ball bearings for high speed motorized spindle will increase the bearing temperature,which will affect the performances of the spindle.In order to analyze the temperature field of high speed angular contact ball bearings accurately,an analysis method is proposed considering the interaction between thermally induced load and friction heat generation.Firstly,the calculation model of total friction heat generation considering the friction caused by differential sliding,spin sliding,load,lubricating oil viscosity,and the calculation model of thermally induced load are established;then the interaction between the two is analyzed;finally,the steady-state temperature field of the bearings is obtained based on finite element analysis software.The results show that:in a steady state,the highest temperature of the bearings is in the contact area between ball and inner ring,and the temperature in the contact area between ball and outer ring is lower;when the thermally induced load is considered,the friction heat generation caused by differential sliding,spin sliding and load is larger than that without considering the thermally induced load,and the friction heat generation caused by lubricating oil viscosity has no change;the contact force between ball and inner ring and the temperature rise considering the thermally induced load are larger than those without considering the thermally induced load.
