It is concluded that the calculation process of spiral guide rail can be simplified when its lead range is integral times of 蟺.Based on the analysis of the cause and process of additional rotation and the additional rotation of the transmission chain of CNC gear shaper, the electronic gear dividing motion chain and the electronic differential tooth motion transmission chain of the numerical control helical gear shaper are obtained, and the relationship between them is obtained.A patent for the design of the drive mechanism of servo differential gear shaper is obtained.
