内三角花键可以用成形刀具单齿分度法在插床上加工,不但效率低,而且很难保证分齿精度。对于小批生产或尺寸过大的内三角花键用拉刀加工也很不经济。在这种情况下,可以利用内三角花键插齿刀在插齿机上加工。该刀具用来加工不通孔内三角花键;用来加工谐波齿轮传动中内三角花键更能显示出优越性。 The internal triangular spline can be formed by single-tooth forming tool in the slotting machine processing, not only inefficient, and it is difficult to ensure the precision teeth. For small batch production or oversize triangular triangular spline processing with broaches is also very uneconomical. In this case, you can use the internal triangular spline gear shaper in gear shaper machining. The tool used to process non-through-hole triangular spline; used to process harmonic gear drive in the triangular spline more shows the superiority.
