| Abstract The present research work concentrates on the effect of contact ratio change on the stresses generated on meshing gear teeth. Many cases of contact ratio (1.6, 1.7, 1.8, 1.9 & 2.0) have been studied. In each case the value and location of load were determined on the involute profile of meshing tooth. Also the angular position of this tooth for critical loading condition (at the instant when the generated root stresses at the maximum state). (Ansys) programming using F.E.M have been applied for stress analysis on gear model. From this study it is clear that, the highest contact ratio resulted in the lowest generated tooth stresses (i.e. the highest load carrying capacity). This depends on the value, location and direction of load applied on tooth involute. Keywords : Spur gear, Contact ratio, Load sharing, Stress analysis | ||
