中文摘要：

轴偏斜是实际运行推力滑动轴承中普遍存在的现象，轴心线的偏斜是造成推力轴承失效的主要原因之一。建立可倾瓦推力滑动轴承弹性流体动压润滑的计算模型，计算5组不同轴偏斜角下的轴承润滑性能，并将其与未偏斜时的润滑性能作对比。结果表明，轴偏斜造成每块瓦的油膜厚度、压力分布、瓦面温度均不相同，其中对油膜厚度、压力分布影响很大，对瓦面温度分布影响较小；在全膜润滑状态下，微小的偏斜角变化会造成最小油膜厚度和最大压力明显的变化，但瓦面最高温度变化很小。

英文摘要：

The misalignment of axis of the bearing shaft exists in the practical operation of thrust bearings, and it is one of the major causes that induce the failure of thrust bearings. A theoretical model of the thermal elastohydrodynamie lubrication for tilting-pad thrust bearings was established, and five eases was calculated to examine the effects of misalignment on the performances of those bearings. Compared with the results of exactly alignment case, the present results show that misalignment of shaft results in the differences of oil film thickness, hydrodynamic pressure and temperature of the pad surface of different pads, and shaft misalignment has significant influences on film thickness and hydrodynamic pressure, but less effects on pad surface temperature ; and that a small change of the misalignment angle yields distinct variations of minimum film thickness and maximum hydrodynamic pressure, however, a little change of the maximum pad temperature, for the thrust bearings under flood lubrication.
