一种消隙机构

Abstract

The utility model discloses an anti-backlash mechanism, which is characterized in that a staggered tooth gear, a pull plate and a driving gear are arranged on a driving shaft; the staggered tooth gear is divided into a part A and a part B, wherein the part A is fixedly arranged on the driving shaft through a key pin, and the part B and the pull plate are fixed together and can rotate on the driving shaft; the driving gear is fixedly arranged on the driving shaft through a key pin; springs are connected between the driving gear and the pull plate; and a driven gear is fixed on a driven shaft through a key pin and is meshed with the staggered tooth gear. Due to the arrangement, the backlash in circular tooth is eliminated.
本实用新型公开了一种消隙机构,其特征在于:在主动轴上安装有错齿齿轮、拉板和主动齿轮,所述错齿齿轮为A和B两部分,A部分通过键销固定安装在主动轴上,B部分与拉板固定在一起,B部分与拉板可在主传动轴上回转,主动齿轮固定通过键销安装在主动轴上,主动齿轮与拉板之间连有弹簧,从动齿轮通过键销固定在从动轴上,所述从动齿轮与错齿齿轮相啮合。通过以上设置,本实用新型消除了齿侧间隙。
