Finite element analysis of stress variation along the depth of gear tooth

Gear system is one of the most important components in any mechanical power transmission system. A gear pair in action is generally subjected to contact loading at the mating surface. In this paper, the stresses due to contact loading have been evaluated on the surface of gear tooth and along the ge...

Gear system is one of the most important components in any mechanical power transmission system. A gear pair in action is generally subjected to contact loading at the mating surface. In this paper, the stresses due to contact loading have been evaluated on the surface of gear tooth and along the gear tooth depth.
