In this paper, the engaging and coodinate changing of internal gear hob, pinion and internal gear are researched, the equations of internal gear hob helicoid, root cutting curve and internal gear hob cutting edge are introduced also. 研究内齿轮滚刀、媒介齿轮的共轭啮合及其坐标变换关系,推导出内齿轮滚刀螺旋面方程式、根切曲线方程式、零前角直槽内齿轮滚刀切削刃方程式。
Correction of a formula for computing tooth addendum arc of internal pinion shaped cutters 对内插齿刀齿顶圆弧计算公式的修正
In the paper, the cartesian coordinates tooth profile equations of external and internal spur gear generated with pinion cutter was derived with the profile normal method, and the calculating method of starting and final point of each curve was given. 应用齿廓法线法,推导出插齿加工的直齿内、外齿轮的直角坐标齿廓方程,给出了齿廓各段曲线起点与终点的确定方法。
