Design and analysis of a spiral bevel gear

Abstract

Spiral Bevel gears are used in power transmission systems with two crossed shafts. The topic of the paper is a model for helping the spiral bevel gear design, depending on meshing parameters. The global parameters of the gear are calculated with the standard ISO 23509 equations. A prediction of the profile modifications has also been performed to center the load pattern on the flank and to minimize the maximum contact pressure. A numerical simulation is achieved with the ASLAN software, developed by LaMCoS laboratory for calculating the quasi-static load sharing of spiral bevel gears.
