In this paper the bending stress over the lower addendum of the spur gear, shear and contact stresses by using the software tools like pro-e and ANSYS are employed to design and analysis. Here in, we report the contact stress analysis of stainless steel spur gears by theoretical method using Hertz equations and by finite element analysis using FEA software ANSYS 15.0 workbench. The spur gear is sketched and modelled in ANSYS design modeller and the contact stress analysis is done in mechanical ANSYS multi-physics. The ANSYS software avoids tedious calculations presumably impending in the design procedure and uses ultimate numerical tool to approximate the solution of the partial differential equations associated with continuity, momentum and energy phases of a flow problem in a 3-D model. The designed 3-D model from Pro-E is inhibited in the ANSYS. This exquisite feature of ANSYS enables designer to optimize the design procedure in an iterative manner based on the final plots of post-processing phase.
