摘　　要：高精度的回转工作台是数控机床的不可缺少重要部件之一,在有些场合需要用到180°定角度转位的回转工作台。设计了一种利用液压缸驱动、齿轮齿条传动,可自动消除间隙的回转工作台。该工作台主要包括工作台、箱体、抬升驱动机构、回转驱动机构以及消隙机构等。该回转工作台能实现定角度转位,自动消除间隙,并且传递扭矩大、结构简单、传动精度高。The rotary table with high precision is an important indispensable part of numercial control （NC） machine tool, and a rotary table with a fixed angle translocation of 180° is needed in some occasions. A gear-rack transmission rotary table eliminating clear-ance automatically was designed driven by hydraulic cylinder. The main parts included in the table were working table, machine box, uplift drive mechanism, slewing drive mechanism, and eliminating clearance mechanism, and etc. The fixed angle translocation was re-alized eliminating clearance automatically. It can obtain large transmitted torque with simple mechanism and high transmission preci-sion.
