众所周知,内齿轮除采用拉削加工方法外,几乎全是在插齿机上进行加工的,特别是中型以上的内齿加工,其生产率极低。为了改变这一状况,谋求适合大量生产的需要,国外(西德、日本)研制成一种新的内齿轮加工方法——切向进给切削加工法(或称作刮齿法)。内齿轮切向进给加工原理,如图所示。这里的刀具轴线与齿坯轴线的交角约为30°,同时进行强制性驱动。基于两者是处在交叉啮合状态,所以在接触点上产生两种滑动。一种滑动是沿齿高方向,在
As we all know, in addition to using internal gear broaching processing methods, almost all in gear shaper machining, especially medium-sized internal gear processing, its productivity is very low. In order to change this situation and seek to meet the need of mass production, a new internal gear machining method-tangential feed cutting (or scraping) was developed abroad (West Germany, Japan). Internal gear tangential feed processing principle, as shown. Here the angle of the tool axis and the axis of the tooth blank is about 30 °, at the same time forcibly driven. Since both are in a cross-meshing state, two types of slippage occur at the contact points. A slip is along the tooth height direction, at
