Design of slider bearings with wall slippage taken into consideration

文中综述了近几年在考虑壁面行为的滑动轴承设计研究中取得的新进展,介绍了如何运用壁面滑移技术进一步改善常规几何形状滑动轴承性能包括增大轴承承载能力,并同时减小轴承摩擦因数。涉及的滑动轴承包括可倾瓦推力滑动轴承、斜面平台推力滑动轴承和向心滑动轴承。将壁面滑移设计在滑动轴承入口区静止表面,可得到较好的技术效果。壁面滑移可使轴承承载能力至少提高30%,使轴承摩擦因数至少降低40%。对这些轴承进行优化设计后可进一步大幅提高其性能,这种新型轴承原理性设计为新型轴承开发提供了很好的理论指导。

In this article,efforts are made to review the design of slider bearings with wall behavior taken into consideration in recent years.The technology of wall slippage is introduced for improving performance of slider bearings with normal geometrical configurations,including increasing the bearing’s load-carrying capacity but reducing its friction coefficient.The slider bearings include the tilted-pad thrust slider bearing,the wedge-platform thrust slider bearing,and the radial slider bearing.It is shown that thanks to the design of wall slippage on the stationary surface in the slider bearing’s inlet zone,desirable technical effects can be achieved.The wall slippage can enhance the bearing’s load-carrying capacity by more than 30%and reduce its friction coefficient by more than 40%.The optimization design ensures further improvement of bearing performance.This fundamental design of bearings provides theoretical guidance for development of new bearings in the future.
