摘要

建立不同结构参数的螺旋面瓦推力滑动轴承润滑模型,并用FLUENT软件进行仿真计算,研究油膜厚度、瓦面螺距以及转速对轴承承载性能的影响规律,为螺旋面瓦推力轴承的设计提供理论基础。结果表明,油膜最高温度随着螺距以及油膜厚度的增加而减小;轴向承载力随着油膜厚度的增加而降低,当最小油膜厚度和转速固定时,存在最优的瓦面升高比使得轴承承载力最大,瓦面升高比为1.4;油膜最高温度与承载力均与转速呈直线型关系;螺旋面瓦的承载力远高于平面瓦。

Abstract

The different structural helicoidal surface thrust bearing lubrication models is built and calculated with FLUENT to analyze the effects of the thickness of the oil film,pitch of the helicoidal surface and angular speed on load capacity of the thrust bearing,which provide the theoretical basis for design of helicoidal surface thrust bearing. The results show that with the increase of the pitch and oil film thickness,the maximum temperature of the oil film is decreased. The axial load capacity decreases with the increase of the oil film thickness.There is an ratio of pad height to the minimum film thickness which maximizes the load capacity when the minimum thickness of oil film and angular speed are constant,the best ratio of pad height to the minimum film thickness is 1. 4. The maximum temperature and load capacity of the oil film are linearly related to the angular speed. The load capacity of the helicoidal surface is much higher than the flat.
