Rim Stress of Thin-Rimmed Gear

The paper deals with the analysis of thin-rimmed gear stresses induced by a load applied to a gear tooth. The stress of spur external gear is determined by means of three-dimensional finite element method and by use of the developed pinion-wheel numerical model. The effect of teeth foundation rigidity variation upon tooth-root and rim stress is established. The comparison of the rim stress magnitude and distribution over the rim internal surface is performed in relation to the rim thickness and by utilizing equivalent stress as relevant one, considering the actual three-dimensionality of spur gear.
