摘　　要：依据传热学、摩擦学等相关理论,建立喷油润滑式可倾瓦推力轴承瓦面油膜温度场,并进行了数值仿真求解,得到了计算结果,可为此类推力轴承的设计、应用提供参考。着重重点介绍了推力瓦上表面温度载荷的施加方法以及推力瓦其余表面对流换热系数的计算与加载。结果表明:喷油润滑工况下推力瓦热变形的最大变形处靠近出油边,整体变形则沿着瓦四边向外膨胀的中凸变形且其变形量已经达到了与油膜厚度同一数量级。The oil film temperature field of thrust tile surface of tilting pad thrust bearing was obtained according to heat transfer,tribology and other related theories.By using the finite element numerical analysis method,the paper mainly introduces the application method of the temperature load on the upper surface of the thrust pad and the calculation and loading method of the heat transfer coefficient on the rest surface of the thrust pad,and the numerical simulation solution of the deformation caused by the temperature of the thrust pad of the tilting pad thrust bearing.Results:the maximum deformation of thermal deformation of thrust shoe is close to the oil discharging edge,and the overall deformation expands outward along the four sides of the warping and is convex in the middle,and its deformation has reached the same order of magnitude as the oil film thickness.
