Abstract

The research aimed to conduct a stress analysis of gears to determine the maximum permissible contact stresses for design purposes and to prevent gear failure resulting from excessive contact stresses. Gears are critical components in mechanical power transmission systems. It is a rotating mechanical element with serrated teeth that interlock with another toothed element to convey torque.  The application of gears encompasses a wide range, from diminutive wristwatches to extensive industrial machinery, such as automobiles, the aerospace industry, and marine engines, due to their remarkable durability and compactness.  Spur gears feature straight teeth that are oriented parallel to the axis of the wheel. The primary objectives in modern gear design are the bending stress and total deformation of gear teeth.  When a pair of spur gear teeth is in use, it usually goes through two types of cyclic stress: contact stress and bending stress.  This report shows the contact stress study of a stainless steel spur gear that was done with ANSYS 15.0 Workbench and finite element analysis. Finite element analysis is a method employed to resolve intricate designs by partitioning them into smaller pieces to facilitate the attainment of desired outcomes. This study aims to determine the maximum permissible contact stress and total deformation of a stainless steel spur gear tooth.
