Fatigue Life of Taper Roller Bearings in Drive Rear Axle Main Gear Reducer

Abstract:

Taper roller bearings are important parts of drive rear axle main gear reducers, and their work property affect behavior of the reducers.The roller bearings are obtained under applied load and inertia force that affects both meshing contact of the gears and raceways of the bearings. The influence is analyzed in this paper to improve the service life of the roller bearings by finite element method in this work. Firstly, a finite element model of roller bearings is established.Stress fields in the roller and the raceway are calculated by adding load and solving. Then,obtaining the maximum stress of the bearings, and the maximum stressand displaced shape are showed. Finally, the fatigue life of the bearings are analyzed by the obtained the maximum stress .
