Abstract
The geometry of a precise involute NGW planetary gear train has been built by Solidworks, the overall finite element model of planetary gear train has been built in ANSYS Workbench. According to the non-linear finite element contact theory and the finite element theory, instantaneous state mesh of Planetary Gear Pair has been simulated dynamically. And the time curve of the maximum stress strain for planetary gear train and the stress law of the mesh for each gear in different tooth profile were obtained. The variation of stress in different tooth profile of mesh has been analyzed to improve the performance of the planetary gear and reliability to provide some theoretical guidance.
