Abstract

The main purpose of this study was to use localised tooth dimensions to determine the magnitude and location of the maximum tensile stress for the spur gear teeth. Log linear equations using Broghamer and Dolan data for stress concentration were developed and compared with the existing equations. It was found that these log linear equations improved the accuracy and decreased the deviation. By comparing tooth geometry and Lewis factor with that given by AGMA, by graphical construction, and by Broghamer and Dolan for involute spur gear teeth, it is shown that FIGS.EXT software accurately generates teeth. Dimensions such as the load height, tooth thickness and radius of the trochoid contour, determined at the various locations of the trochoid contour, were used to determine maximum nominal tensile stress and its location in FIGS.EXT software for involute spur gear teeth. This location defined as the theoretical weakest location, and its corresponding dimensions were recorded as the localised dimensions. As a function of these localised dimensions, a single log linear equation is developed for stress concentration factor. (Abstract shortened by UMI.)
