Abstract

This study performs the bending and contact stress analyses for a pair of mating gears during rotation. The interested gears are used for a railway reducer. In general, the railway reducer needs high speed rotation, which leads to a large gear ratio. Thus, it is not easy to apply finite element method to investigate the strength performance, since the size of a gear is much larger than that of a pinion. In this study, the bending and contact stresses determined from FEM are compared with the values determined from the ISO code.
