In this paper a simple method to minimize the Peak to Peak Transmission Error (PPTE) for a spur gear set is proposed.
A parametric analysis using advanced software was performed to obtain a general understanding of the problem. Optimization variables were reduced to the Start Relief Roll Angles.A parabolic topography was assumed for the tip relief and either Low Contact Ratio (LCR) or High Contact Ratio (HCR) spur gears have been considered. Meshing related constraints on optimization have been taken into account. On the basis of parametric analysis an effective optimization procedure has been suggested for LCR that can be extended even for HCR.
