中文摘要：

对推力关节轴承进行滑动摩擦试验,在受轴向载荷时,利用红外热像仪和红外测温仪分别测量了轴承侧表面温度及滑动接触区域温度;考虑轴承游隙,建立了结构-热顺序耦合分析模型,结合测得的动态摩擦因数实现了温度场的重建。结果表明：所建立的温度场分析模型满足分析需要;轴向载荷下推力关节轴承的摩擦热产生于球面底端,轴承外表面与滑动接触区域存在较大温差,该温差随着摩擦生热率的增加有变大趋势。

英文摘要：

The sliding friction test is carried out for thrust spherical plain bearings,the temperature of lateral surface and sliding contact area of axially loaded bearings are measured using thermal infrared imager and infrared thermometer. A structure- thermal sequential coupling analysis model is built with considering clearance of bearings,and then the temperature field is rebuilt combining with measured dynamic frictional coefficient. The results show that the analysis model for temperature field meets the analysis requirements. The frictional heat of thrust spherical plain bearings under axial load concentrates at the bottom of spherical surface,there is large temperature difference between outer surface and sliding contact area,and the temperature difference increases with the increase of friction heat generation rate.
