The principle of profile modified face-gear grinding based on disk wheel

•A progressive grinding method for profile modified spur face-gear is developed.•The third action principle of profile modified face-gear driving is established.•The calculation method of swing angle range is established.•The simulation processing test verifies the correctness of the method developed.

In view of the disadvantages of the current grinding method for profile modified spur face-gear, a progressive grinding method is developed. The third action principle of modified spur face-gear driving and the mathematical model of parabolic rack cutter, spur gear cutter, disk wheel and modified spur face-gear are established, based on the theories of differential geometry and gear mesh. The calculation method of swing angle range of the complete grinding of the profile modified spur face-gear is established through the research on the surface contact line area. The simulation processing test based on Vericut software verifies the feasibility and correctness of the method developed. The study provides an effective approach to highly efficient and precise grinding of the profile modified spur face-gear.
