| 摘 要： | 扭轮摩擦驱动是集摩擦传动和螺旋传动为一体的传动系统，它既具有摩擦传动动态特性好，同时又有螺旋传动导程小的特点。本文介绍一种扭轮摩擦驱动系统，它的导程小于０．２ｍｍ，行程为２５０ｍｍ，运动分辨率可达纳米级水平。它由扭轮摩擦传动机构、气体静压导轨及相关部件组成，是一种大行程高分辨率的新型驱动系统。

| Abstract: | Twist roller friction drive system combining friction drive with screw drive,has many features such as good dynamic characteristic of friction drive and small lead of screw drive.This paper presents a kind of twist roller friction drive system.Its lead is less than 0.2mm,the stroke is about 250mm,and the resolution is several nanometer.It is composed of twistroller friction drive mechanism,static air bearing guideway and relative parts.It is a new kind of drive system with large stroke and very high resolution. |
