Simulation of the machining principle of hobbing and grinding cycloidal gears with worm cutters and hobbing tests
The cycloid gear is a core component of the RV reducer
and its high-efficiency and precision machining methods are crucial for ensuring the performance of the reducer. In view of this
the basic principle methods of hobbing and grinding for the cycloid gear are proposed.
Methods
2
Firstly
the meshing equation was solved through the principle of helical surface formation and spatial coordinate transformation
and geometric motion models of the closed tooth profile curve of the cycloid gear
the worm cutter
and tooth-direction modification were established. Secondly
the principle prototype of the hobbing and grinding machine is constructed using VERICUT software. Through the motion simulation of the formed surface and comparison with the theoretical surface
the deviation is less than 0.004 mm.
Results

Through the hobbing processing test
the correctness of the established theoretical model and the feasibility of the worm cutter hobbing and grinding processing technology are verified. This lays a theoretical and practical foundation for the high-efficiency machining of the continuous tooth profile of the cycloid gear and three-dimensional topological modification.
