刨齿机刨齿是被切齿轮与冠形齿轮作无侧隙啮合的过程。冠形齿轮的齿面,是由安装在机床摇台上的刨齿刀切削刃相对于摇台运动轨迹表面来代替。被切齿轮是与冠形齿轮之间产生相对滚动而切出的齿形的。设被切齿轮的齿形角为α,刨齿刀的齿形角α0。当α=α0时,不需改变滚动比。此时, Planing gear planing gear is cut gear and crown gear without backlash meshing process. Crown gear tooth surface, is installed in the machine shaking table by the shaper cutter cutting edge relative to the rocking track surface instead. Cut gear is generated with the crown gear relative rolling and cut out of the tooth shape. Assume that the gear tooth angle of the gear to be cut is α and the gear tooth angle α0 of the gear tooth cutter. When α = α0, there is no need to change the roll ratio. at this time,
