Research on Grinding Wheel Dressing and Tooth Flank Topology Control for Generating Grinding of Internal Helical Gears

Internal helical gears offer advantages such as high transmission accuracy and smooth operation, making them widely used in transmission systems such as electric vehicle reducers and wind turbine gearboxes. Based on the conjugate surface enveloping theory and the spatial meshing principle, this manuscript performs the modification calculation of the spherical worm grinding wheel profile and the tooth flank topology of the internal helical gear. Numerical examples are introduced to calculate the discrete points of the modified tooth surfaces of the spherical worm grinding wheel and the internal helical gear, as well as to construct the corresponding models. The dressing motion control for the spherical worm grinding wheel profile and the internal helical gear tooth flank topology is realized. By investigating the implementation methods of the spherical worm grinding wheel dressing and the generating grinding process for internal helical gears, a feasible technical solution for efficient generating grinding is developed, providing a theoretical foundation for the large-scale application of internal helical gears.
