Abstract

Gear is one of the most critical components in mechanical power transmission system and most industrial rotating machinery. This project mainly focuses on the failure analysis of a starter gear pinion using ANSYS. The preliminary effort is done by collecting failed gear components and by reverse Engineering. All the gear parameter was taken using profile projector and gear tooth vernier caliper. With basic dimension redesign of the same gear and pinion is made using conventional procedure, with available basic dimension such as module, pitch circle diameter involute 2D profile is drawn and convert into 3D model using same software and stress analysis is done using ANSYS-17Version. With available data of stress the possibility of changing the profile is tested on existing involute tooth by changing form factor and center distance if not, profile is drawn using S-shaped transition curve using T-Bezier function. The same curve is modeled using Pro-E and then analyzed using ANSYS and check subsequently weather any reduction in stress was taken place.
