Rim Stress Analysis of Thin-Rimmed Gear
The research into the stress state of gear rim has been based on the developed model of pinion-wheel system and the finite element application. For a spur gear structure of middle web position, the assumption of load distribution in the contact area that reflects, first of all, the tooth support deformation, has been not required for the imposed boundary conditions. To study the influence of web thickness stiffening effect on the inner rim surface stress, the ranges of rim and web thickness values have been considered. The area of stress along the rim circle and tooth facewidth has been shaped and discussed in relation to maximum rim stress appearance.
