摘要

研究准双曲面齿轮动态啮合有限元分析模型的构建方法,建立了合理的有限元模型。基于接触动力学的基本理论和显式有限元分析方法,对准双曲面齿轮的动态啮合性能进行了研究,得到啮合接触冲击特性、齿面接触区域、齿面接触应力及齿根弯曲应力等在轮齿动态啮合过程中的变化规律。以转速和负载两个典型的工作条件为变量,建立对比分析模型,研究转速和负载对准双曲面齿轮动态啮合性能的影响。转速对准双曲面齿轮动态啮合性能影响显著,而负载对准双面齿轮的动态啮合性能影响则跟转速有关,随着转速的增大,相同的负载变化对动态啮合性能的影响逐渐减弱。

Abstract

The method to build finite element model for dynamic meshing analysis 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 gear in dynamic meshing was studied. Obtained the laws of gear motion, the contact area, the contact stress and the tooth root bending stress in the dynamic meshing of hypoid gear. Take the example of the two typical work factors like speed and load. The influences of speed and load on the dynamic meshing characteristics were discussed. The contrast research shows that the rotational speed has an obvious influence up on the characteristics of the hypoid gear in dynamic meshing, and that 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 becomes gradually weakened.
