摘要

为研究瓦面环形槽对推力滑动轴承承载性能改善的优势，基于计算流体动力学（CFD）理论，建立了环形槽斜平面推力滑动轴承油膜分析模型，通过数值模拟，得到环形槽的平面区域占长比、深度和宽度对环形槽斜平面推力滑动轴承承载性能的影响规律。结果表明，推力轴承的承载力和油膜压力峰值随环形槽在平面区域的占长比的增加呈现先增大后减小的变化规律，并且随着环形槽占长比的增加，轴承温度逐渐下降；环形槽宽度一定时，深度的增加使得推力滑动轴承油膜压力分布明显改变，承载力呈现先增大后减小的变化规律；环形槽深度一定时，轴承承载力随着环形槽宽度的增加而增加；在斜平面推力滑动轴承瓦面增加特定环形槽结构，有利于提升承载性能。

Abstract

In order to study the advantages of the annular groove of the tile surface on the bearing performance of the thrust sliding bearing，based on the theory of computational fluid dynamics (CFD)，the oil film analysis model of the inclined plane thrust sliding bearing with the annular groove is established. The law of influence of depth and width on the bearing performance of annular groove inclined plane thrust sliding bearing. The results show that the bearing capacity and peak oil film pressure of the thrust bearing increase first and then decrease with the increase in the proportion of the annular groove in the plane area，and as the proportion of the annular groove increases，the bearing temperature gradually decreases. When the width of the annular groove is constant，the increase of the depth makes the oil film pressure distribution of the thrust sliding bearing change obviously，and the bearing capacity shows a change law that first increases and then decreases，the depth of the annular groove remains unchanged，and the bearing capacity increases with the increase of the width of the annular groove Increase，adding a specific annular groove structure on the inclined plane thrust sliding bearing pad surface is beneficial to improve the bearing performance.
