This paper dealt on the effect of change of contact ratio on the contact fatigue stresses generated on meshing involute spur gear teeth during operation. In this study, different cases of six contact ratio gearing between 1.6 and 2.0 have been analyzed. For each contact ratio the rate of load sharing and angular and radial position of load were determined on the involute profile of meshing tooth of each gearing to determine contact fatigue stress at critical
condition. To come up at the result CATIA and Solid Works software involute spur gear models have been developed
for stress analysis on ANSYS Workbench (FEM). Because of the decrease in value and the change in location and
direction of applied load, higher contact ratio gearing resulted higher generated tooth fatigue contact stress life. The
results obtained from ANSYS Workbench are compared with results of the AGMA gear formula results.

Keywords: Gear teeth, ANSYS, contact ratio, contact fatigue, AGMA
