摘要

气足是气体静压止推轴承的一种

是气浮导轨中最常见的部件。气足根据其形状又分为矩形气足与圆盘气足。圆盘气足广泛应用于三坐标测量机中。本文利用线性气源假设

将气膜中的气体二维流动化为一维流动

使雷诺方程得到简单的解析解

推导出了圆盘气足承载能力的工程计算方法

从而为气浮导轨中圆盘气足的设计找到了一条有效、快捷的途径。

Abstract

Air feet are a sort of externally pressurized gas lubricated bearing. Air feet are common structure form of air-guide. According to shape of air feet

air feet are divided into rectangle air feet and circle air feet. Circle air feet are widely applied to three-COMERO. This article assumes that airflow is linear. Because it assumes that two dimension flow is one-dimension flow between bearing and guide

the Renault-equation has resolution. A more practical engineering method of calculation about loading capacity of circle air feet is described in this article.
