- Abstract:
- ANSYS finite element software is used as a tool to simulate the compressive residual stress of carburizing and quenching gear by applying prestress to gear. Since the compressive residual stress varies with the depth of material, in order to facilitate the simulation of the compressive residual stress in each layer by layering the surface layer of gear teeth. Under the same load conditions, the compressive residual stress gear produced by carburizing and quenching and the absence of compressive residual stress gear are respectively analyzed for flexural strength and fatigue life, in order to study the compressive residual stress’s influence on flexural strength and fatigue life of gear. The results of the analysis show that the compressive residual stress can make gear flexural fatigue resistance improved
