Abstract: Superior performing gear drives need the hour for enhanced endurance to transmit loads at high operation speed. Also, at the same time, it should cost less and have an extensive operation lifecycle. In some cases, like automobile drives, Jet-Engine gearbox, wind turbines drive, etc., the Loading is uni-directional. This influenced the evolution of Asymmetric gear teeth where the drive side is not symmetric with the coast side. This study evaluates the contact stresses of an asymmetric spur gear-pair, where the drive side pressure angle is modified. A novel boundary condition method for Contact analysis is evoked to achieve continuous teeth contact. Abaqus was utilized to numerically solve the spur gear pairs in contact and determine the stresses developed at the contact region. FEA results obtained were correlated with standard analytical approaches like Hertz contact theory and AGMA methods. Python scripting was implemented in conjunction with Abaqus to automate the design & computational process. The numerical analysis evaluated the contact stress regime under continuous contact conditions along the Line of action. The simulation results indicate that the stress distribution of the gear surface is governed by an alteration of the tooth pressure angle.
