摘要
提出了利用现有球形滚刀与改造滚齿机加工面齿轮的方案.推导了球形滚刀基本蜗杆螺旋面方程,建立了滚切面齿轮的坐标系统.通过对成形误差曲面的研究发现用现有球形滚刀加工面齿轮的理论造形误差很小,且远小于插齿成形误差.轮齿接触分析表明滚切得到的面齿轮与标准圆柱齿轮啮合轨迹的位置及方向与理论啮合轨迹基本一致,而滚切得到的面齿轮副传动误差为有利的抛物线形.该文的研究为面齿轮的加工找到了新方法,并为球形滚刀开辟了新用途.
A scheme for cutting face gears with a sphericity hob and reconstructive hobbing machine was proposed.The basic worm helicoid surface of sphericity hob was deduced,and the coordinate systems for cutting face gears were established.The error difference surface research indicates that theory surface error of the face gear using sphericity hob is very small.The forming error of hobbing is much less than that of slotting cutter.Tooth contact analysis(TCA)indicates that the contact path position and direction ar...
