摘　　要：以推力轴承扇形瓦块为研究对象,采用柱面坐标,通过对二维雷诺方程进行离散化求解,计算得出水膜厚度、压力和温度场的分布规律,并研究推力环转速、推力瓦倾角和潜水深度对轴承润滑性能的影响规律。研究表明:最大水膜压力和推力瓦最高温度均出现在推力瓦出水口靠近外径的位置。Sector-shaped thrust pad of thrust bearing was investigated. Adopting cylindrical coordinates to discretize the two-dimensional Reynolds equation,the thickness and pressure of water film,temperature field of thrust pad were computed.The effect of thrust ring speed,thrust pad angle and submersible depth on the lubrication property of thrust bearing.The result shows that the largest pressure of water film and the highest temperature of thrust pad are all located in the area of circumferential direction of the thrust pad outlet.
