| dc.description.abstract | The present research work dealt on the effect of change of contact ratio on the contact fatigue stresses generated on meshing spur gear teeth during power transmission. In the study different cases of six contact ratio gearing between 1.6 and 2.0 have been analyzed. For the different contact ratios considered the rate of load sharing and angular and radial position of load were determined on the involute profile of meshing tooth of each gearing. In addition to that the different stress conditions of this tooth for critical position (at the instant when the generated contact stress is at the maximum state) are determined. To come up at the result CATIA and Solid Works software involute spur gear models have been applied for stress analysis on ANSYS Workbench (FEM). From this study it is clear that, the higher contact ratio resulted in the higher generated tooth fatigue contact stresses life (i.e. the highest load carrying capacity). This is because of the decrease in value, and the change in location and direction of load applied on tooth involute in mesh to transmit power. At last the results obtained from ANSYS WB are compared with results of the AGMA gear formula results. They are comparable to each other. | en_US |
