摘 要：Established a finite element model ofhypoid gear of a micro-car rear final drive,analysis of the hypoid gear mode and static contact by means of finite element analysis,obtained the surface of gear contact stress distribution in the different installation position,The results show that the finite element simulation exactly reflects the impact of the installation location of the hypoid gear to contact fatigue strength of gear,providing a theoretical basis for the design and installation of the gear.
