Fatigue Life Analysis Based on Involute Gear Profile Modification
The paper proposes a new gear involute profile modification method.The gears before and after modification are modeled by UG.Based on the fatigue life theory,the gear CAE model is established by the Workbench and Fatigue Tool methods to complete the gear contact dynamics and fatigue life simulation analysis.The results show that the maximum equivalent stress and equivalent strain of the gear before and after modification appear at the pitch line and the tooth root of the gear,and the data results of the modified gear are better than those of standard one.
