Finite element analysis of Spiral bevel gears pair used in an Automobile Differential gear box

Abstract

This paper covers the static, fatigue, modal and harmonic analysis of Spiral bevel gears pair used as drive pinion and crown wheel in the differential gearbox of Tata Ace vehicle, using a popular commercial finite element analysis software ANSYS. The main goals are to estimate the life and early detection of failure of the spiral bevel gears pair, during operation. The solid models of gears are created by using the widely used solid modeling software CATIA V5. The goals are achieved by comparing the results of FEA of new gears pair with the results of gears pair having a crown pinion with one tooth broken. A review of work done so far on Finite element analysis of bevel gears is also presented.
