Abstract

The aim of this paper is to study the spiral bevel gears with new tooth profile, named circular arc. This profile will guarantee higher load carrying capacity, higher power transmission efficiency, and longer operating life. A mathematical model is proposed for spiral bevel gears having circular arc tooth profile, where all geometry calculations are performed using MATLAB software package. The mathematical model includes spiral bevel gears for both Gleason and Klingelnberg manufacturing systems. The solution of the single meshing constraint equation for gears with intersecting axes is taken into consideration for gear geometry calculations. The proposed mathematical model is then validated using CATIA software package through solid modelling of different gear designs. These trials included different values of the various design parameters of spiral bevel gears to ensure that the mathematical model is valid for different design cases. This validation is completed with an interference check step performed through dynamically simulating meshing between a pair of gear set through CATIA software package.
