Gear Application Feasibility Study of Functionally Gradient Material

Abstract:

The problems of the tooth root bending stress increase,distortion, the life of the gear reduction and other issues existing in the gear heat treatment process, In order to solve these problems, functionally gradient material (FGM) was used on gear working surface. the analysis of heat treated gear performance and common gear performance comparison analysis has maded; A functionally gradient material cylindrical involute gear model and a common cylindrical involute gear model were created, Then finite element calculation of bending stress and analysis of the two models has maded. The FGM gear have better performance on the root bending stress and the hardness of the working surface, and also can avoid disadvantages about distortion and uniform carburized layer which might happened in heat treatment process. The experimental results show that FGM can be used on gear.
