A Geometrical Optimization Approach to Minimize Contact Stress in Mating Gear Teeth

This paper presents a technique to minimize contact stress in mating gear teeth. The American Gear Manufacturers Association (AGMA) approach uses contact stress equation that is highly detailed and requires many factors, charts, graphs and tables to produce limiting value of the contact stress. Departing from the complex AGMA approach, this paper utilizes the Hertzian contact stress equation to develop an optimization technique based on the geometry of the surface in contact for the minimization of the contact stress.
