内斜齿轮通常是采用专用的斜齿插齿刀在带有专用螺旋导套的插齿机上进行加工的。但是,常常由于斜齿插齿刀和螺旋导套的加工比较困难,并且螺旋导套在规格上有时不易满足需要。国外,在一般滚齿机上采用一种“蜗旋滚刀”来加工内齿轮,对我们有很大的启发。我们在一九七三年为高速行星齿轮箱中的内齿圈设计了这种滚刀,由于对切削余量的分配问题认识不足;在齿形方面只是从定性的概念出发采用直线十分近似地代替刀齿曲线,因此结
Internal bevel gear is usually a special bevel gear shaper cutter with a dedicated helical gear shaper for processing. However, it is often difficult to machine helical gear shanks and helical sleeves, and the helical sleeves are sometimes not easy to meet specifications on a gauge. Abroad, in a general gear hobbing machine using a “spiral hob” to process the internal gear, we have great inspiration. We designed this type of hob for the ring gear in a high-speed planetary gearbox in 1973 and we do not know enough about the allocation of cutting allowances; we just use the straight line for approximation Instead of a tooth curve, so knot
