一、问题的提出《工具技术》杂志1979年第4期刊登了一篇译自德刊《工业通讯》1978№46的文章《滚齿时工作后角的意义》。在此文章中,首先阐述了在滚齿过程中齿轮滚刀后角变化的问题。文章的作者,根据滚刀的切削速度V_F 和滚刀相对于被切齿轮旋转运动的相对速度分量V_A的合成,求出了滚刀刀刃上各点的合成运动方向(如图1所示),并据此结论性地指出:“滚齿时,工作后角与设计后角会有显著差别的,滚刀侧刃上本来较小的后角,在一定条件下变为零,在极端条件下,甚至为负值。”并
First, the issue put forward “Tool Technology” magazine in 1979 fourth issue published an article translated from the German journal “Industrial Communication” 1978 № 46 article “after hobbing work angle meaning.” In this article, the problem of changing the clearance angle of the gear hob during the gear hobbing process is explained first. The author of the article finds the resultant movement direction of each point on the hob edge (as shown in FIG. 1) based on the combination of the cutting speed V_F of the hob and the relative speed component V_A of the hob relative to the rotary motion of the cut gear. And conclusively pointed out that: “hobbing, the working angle and the design of the rear angle will be significantly different, hob side of the blade originally had a smaller clearance, under certain conditions to zero, under extreme conditions , Even negative. ”And
