摘要

由轮齿接触分析以及轮齿承载接触分析计算出考虑安装误差的轮齿啮合刚度,建立了考虑时变啮合刚度激励、啮合冲击激励和齿侧间隙激励的人字齿轮系统十二自由度啮合型弯—扭—轴耦合非线性振动模型。以某船用单级人字齿轮副为实例,研究了多载荷下人字齿轮左端啮合副周向的振动特性,结果表明,外载荷的增大使得啮合刚度激励和啮合冲击激励下系统的振动均增大,且啮合冲击激励对外载荷的敏感性高于啮合刚度激励,而齿侧间隙激励下系统的振动则随着外载荷增大而减小。同时,啮合冲击激励对系统振动的影响随着载荷增大而增大,而啮合刚度激励和齿侧间隙激励则随着载荷增大而减小。

Abstract

Teeth meshing stiffness is calculated by tooth contact analysis and load tooth contact analysis, and 12-degree of freedom nonlinear double helical gear vibration model is established considering meshing stiffness, corner mesh impact, and backlash. With the ship transmission system as an example, the vibration characteristics of left meshing gear pair under multi-load are studied. The results show that the system vibration under meshing stiffness excitation and corner mesh impact excitation both increase with the load torque increased, and that the corner mesh impact excitation is more sensitive to changes in load than meshing stiffness excitation. However, vibration of the system decreases with the external load in backlash excitation. Meanwhile, the corner mesh impact has a growing effect on the system vibration with the load while the meshing stiffness and backlash excitation have diminishing effects.
