部节流静压、动静压支承中节流腔新结构及其不同布置时的支承性能

The Bearing Propertics of Hydrostatic and Hydrodynamic Hydrostatic Bearing with the New Structural lnner Throttle Cavititics in Differegt Positions

本文提出了一种用于内部节流支承的节流腔新结构,给出了它在不同布置时支承的承载能力与刚度的简化公式并分析了主要参数对支承性能的影响,指出这种结构可明显地改善内部节流支承的性能,具有推广使用价值。

In this article, a new kind of structural throttle cavitics which are used for inner throttle bearing is researched. The simplified formulae of load-bearing capacity and rigidity of the bearing are presented when the inner throttle cavities are in diffcrent positions and the influence of main parameters on the bearing propertics is analyzed. This article also proved that the propertics of the inner throttle bearing can be improved distinctly by the new structure of the new throttle cavities and it has the value of usage and popularization.
