Abstract
Classical deterministic gear design approaches (i.e., AGMA, JGMA, FEM) do not incorporate variations in material properties, surface hardness, operating conditions, and geometric tolerances. Often, an analysis is made by considering some misalignment in one of the directions. As a result, over or under design of gear occurs. In the present paper, a design methodology to incorporate uncertainties associated with system input has been proposed and contact fatigue failure of spur gears have been considered. A detailed description of the procedures followed for the AGMA, and the proposed probabilistic approach is presented. The proposed approach is validated against established results obtained through finite element analysis (FEM), providing a more reliable and robust framework for gear design against contact fatigue.
