Abstract

Abstract:

In order to investigate influence of distribution type on hydrodynamic performance of gas lubricated inclination-dimpled surfaces,experiments were carried out herein.Surfaces of three typical distribution types,part-textured,full-textured and double-row-textured,were investigated,and film thickness and friction torque were measured during testing.Results show that,the coupling faces can separate quickly with increasing rotation speed.Another important result is that the part-textured surface has larger hydrodynamic effect than that of the full-textured while the double-row-inclination-dimpled surfaces has the strongest hydrodynamic open force.The hydrodynamic effect increases with increases of rotation speed.The experimental results agree well with theoretical analysis,which provides experimental dependence for design of micro-pored surfaces.

Key words: inclined dimple, distribution type, gas lubrication, hydrodynamic effect

摘要：

以倾斜椭圆微孔表面为研究对象,开展了微孔排布方式对倾斜微孔气体润滑动压特性的实验研究。实验中对部分开孔、全开孔以及双列开孔3种典型分布形式倾斜微孔表面的气膜厚度和摩擦扭矩进行了测量,结果表明:倾斜微孔表面可保证摩擦配副表面迅速打开;在相同孔型几何参数条件下,微孔的排布方式对倾斜微孔表面的动压性能影响明显,部分开孔表面优于全开孔表面，而双列开孔表面的动压效果最好;转速越高，倾斜微孔结构的导向作用越明显,动压效应越强,气体润滑成膜能力越好。实验结果与理论分析一致,为多孔端面结构设计提供了实验依据。
