Profile design of grinding wheel and temperature field analysis of internal gear with parabola curve configuration

In order to further advance the manufacturing and precision machining of the internal meshing gear with parabola curve configuration, we offer a grinding manufacturing process in this study. Based on the fundamental principle of gear transmission, in the form grinding process, we calculate the gear-wheel contact line equation using Newton–Raphson method. Furtherly, we established the spatial coordinate system for the grinding wheel-internal gear and derived the normal profile of grinding wheel for forming process. To estimate tooth profile errors after simulating the form grinding process, we introduced an enhanced transversal algorithm and the outcomes affirm the accuracy of the form grinding process. A single tooth of the meshing gear is created and the simulation analysis to investigate the influence of different grinding parameters on temperature variation was also carried out under both dry and wet grinding conditions. This information will be instrumental in optimizing and controlling temperature during the grinding process. The research conclusions provide a crucial theoretical basis and engineering analysis for the practical application of new internal gears in form grinding.
