环隙节流静压轴承静动态特性的理论与试验研究及应用

Theoretical analysis and experimental investigation, of static and dynamic characteristics of ring-gap flow-restricted hydrostatic bearing and its application

本文在考虑了油液本身及其所含气体可压缩的前提下,对环隙节流静压轴承的静动态特性进行了理论与试验研究,并将其应用于371型磨床主轴上,获得了较高的加工精度。

This paper carries out theoretical and experimental investigations into static and dynamic characteristics of ring-gap flow-restricted hydrostatic bearing in consideration of the compressibility of oil itself and air contained in it. The bearing is applied to the spindle of Type 371 grinding machine, with obtaining higher working precision.
