在综合考虑斜齿轮啮合刚度、轮辐弯扭刚度以及传动轴－轴承支承刚度的基础上，建立了斜齿轮副的耦合振动模型，介绍了系统刚度的计算方法，分析了系统的固有振动特征及其螺旋角的影响，实例分析结果表明：螺旋角不仅引起斜齿轮复杂的耦合振动，而且它的变化将会造成斜齿轮轴向、扭摆共振频率比较大的改变，而对径向共振频率的影响不大；斜齿轮的径向和扭转共振会造成齿轮很大的动载荷，而轴向共振的这种影响则不显著。
Based on the consideration of the meshing stiffness of helical gears, the torsional stiffness of the spokes and the bearing-bearing stiffness, the coupled vibration model of helical gear pair is established. The calculation method of the system stiffness is introduced. The natural vibration characteristics of the system and its The results of the example analysis show that the helix angle not only causes the complicated coupling vibration of the helical gear, but also the change of the helical angle will cause a large change of the resonance frequency of the helical gear in both axial and torsional directions, but not the radial resonance frequency Large; helical and radial helical gear resonance will cause a great dynamic load, while the axial resonance of this effect is not significant.
