In this paper results are presented from a two-dimensional finite element stress analysis of three tooth sector of spur gear and the boundary conditions are provided at the radial end of the teeth of the rim. The different diametric ratio from 1.02 to 2 is used to get the stress variation. In the analysis of this three tooth sector the Maximum Principle stresses and von mises stresses at the root and fillet are in consideration. The main objective of this paper is to find out the minimum thickness of spur gear for different diametric ratio Md using analytical results by Lewis equation and FE results. In this study the CATIA software used for the geometrical construction and stress analysis is accomplished by commercial finite element package MSC PATRAN and NASTRAN.
