摘要

研究了真空吸浮式止推轴承静态特性。在真空度、供气压力、真空腔半径、节流孔分布圆半径等参数相应变化情况下

给出了轴承静态特性和气膜厚度关系。同时

把气膜厚度作为真空度变量与导管参数、轴承参数联系起来

为定量分析真空度对轴承特性的影响提供了理论依据。

Abstract

This paper studies the static characteristics of an externally pressurized gas-lubricated thrust bearing with a vacuum-pocket. Relations between the static characteristics of the bearing and depth of airfilm are summarized when source pressure

vacuum degree

vacuum-pocket radius and distribution-circle radius(on which the orfiles are distributed)are introduced respectively.Depth of air-film regarded as a function of vacuum degree relates with parameters of the vacuum-pipe and the bearing

so as to get the basis of theory for quantitative analysis.
