Abstract
The present study evaluates on the contact stresses of an asymmetric spur gear pair, where drive side pressure angle is modified. A novel method of boundary condition for Contact analysis is evoked in order to achieve continuous teeth contact. Abaqus was utilized to numerically solve the spur gear pairs in contact and to determine the stresses developed at the contact region. FEA results obtained were correlated with standard analytical approaches like Hertz contact theory and AGMA methods. Matlab and Python scripting was implemented to automate the design & computational process. The numerical analysis evaluated the contact stress regime in detail under continues contact condition along the Line of action.
