The length of the working section is limited as follows: that is, the normal line of the tooth profile passing through the end of the length of the working section should pass within the center point of the adjacent tooth slot. The tooth shape of the working section can be. It is convex or linear, but it should be smoothly connected with the tooth groove arc and tooth arc.
