摘要
基于有限单元法,建立了一种全自由度人字行星齿轮传动系统动力学模型。模型将时变啮合刚度、综合啮合误差和啮合相位作为动态激励,分析了太阳轮轴柔性和行星轮轴柔性对人字行星齿轮传动系统中内外啮合动态啮合力和动态传递误差的影响。结果表明:轴的柔性变形对人字齿轮行星传动系统的动态特性具有显著影响,考虑轴柔性后,人字齿轮左右两侧斜齿的均载性能得到显著改善,且太阳轮轴柔性比行星轮轴柔性对均载性能的影响明显。
Based on finite element method,established a full freedom of planetary gear transmission system dynamics model,the time-varying mesh stiffness and comprehensive meshing error and mesh phase as a dynamic incentive,analyses the influence of the sun wheel and axle flexible and planetary shaft flexible herringbone meshing planetary gear transmission system of inside and outside the influence of dynamic meshing force and dynamic transmission error.The results show that the flexible deformation of the shaft has a significant effect on the dynamic characteristics of the planetary transmission system with herring gear.Considering the shaft flexibility,the load sharing performance of the left and right helical teeth of the herring gear is significantly improved,and the influence of the solar shaft flexibility on the load sharing performance is more obvious than that of the planetary shaft flexibility.
