Finite element analysis for dynamic meshing of a pair of hypoid gears

The method to build a finite element model for dynamic meshing analysis of a pair of hypoid gears was discussed.A reasonable finite element model was introduced.Based on the theory of nonlinear dynamics and finite element explicit algorithm,the characteristics of the hypoid gears in dynamic meshing were studied.The laws of gear motion,the contact area,the contact stress and the tooth root bending stress in dynamic meshing of hypoid gears were obtained.The two typical working factors: votating speed and load were taken as variables.The influences of rotating speed and load on the dynamic meshing characteristics were discussed.The contrast study showed that rotational speed has an obvious influence on the characteristics of the hypoid gears in dynamic meshing,and the influence of load is related to the rotational speed;as the rotational speed increases,the influence of the same load change on the dynamic meshing characteristics gradually decreases.
