Tooth-Root Stress Distribution Related to Gear Rim and Web Thickness

The paper deals with the research into the effects of rim and web thickness on the stress distribution along a spur tooth facewidth in the root area. Under the assumption of machining errors and assembly misalignments absence, the contribution of certain gear structure to non-uniform stress distribution has been analysed. The investigation has been performed by means of the 3D FEM and the developed model of pinion-wheel system. The chosen values of rim thickness cover the corresponding ones for thin rim, and the values of web thickness are in accordance with the recommendations in practice. Two different gear structures have been taken into consideration i.e. the cases of middle and offset web position.
