该齿轮由两个传动参数相同的圆柱齿轮组成,齿轮2固定在轴套1上,齿轮3用拉簧5与固定齿轮相连接,在轴套上呈浮动状态。当与其它齿轮啮合时,先将浮动齿轮3相对于2转过几齿,弹簧被拉开,使消隙齿轮齿部与啮 The gear consists of two cylindrical gears with the same transmission parameters, the gear 2 is fixed on the sleeve 1, the gear 3 is connected with the fixed gear by the tension spring 5, and the sleeve is floated on the sleeve. When meshing with other gears, the floating gear 3 rotates a few teeth relative to the first two, the spring is pulled open, so that the anti-backlash gear teeth and mesh
