Description

We developed a method for calculating eigenvalue of planetary gear system that is considered elastic deformation of ring gear. The purpose was to develop technology that can be used to evaluate resonance conditions of planetary gear system. We assumed that (1) ring gear is elastic body, (2) tooth of gear and bearing are spring, (3) sun gear does not oscillatory, and we executed a numerical analysis. We examined that planet career vibration is caused by structure coupled vibration of ring gear and planet gears.
