人字齿轮在舰船传动系统中有着广泛的应用，本文为研究中心距变化对人字齿轮啮合动力学特性的影响，建立齿轮啮合的动力学模型，理论分析了中心距对齿轮啮合刚度以及啮合重合度的影响，利用ADAMS动力学分析软件对人字齿轮进行了啮合动力学特性分析。结果表明，在标准啮合的基础上增加啮合中心距，啮合重合度及啮合刚度都随之减小，啮合冲击随之增大，啮合频率的高次谐波分量幅值增加，增大了齿轮系统发生共振的风险，中心距相较于标准值有微小变化就会带来较大的啮合冲击激励。
Herringbone Gear has widely application in transmission system of ships and warships. In this paper,in order to study the influence of center distance change on the meshing dynamics of herringbone gears, the dynamic model of gear engagement was established, the influence of center distance on meshing stiffness and engagement degree was analyzed theoretically, the meshing dynamic characteristics of the gears were analyzed by using ADAMS. The results show that the increase in the basic standard of meshing center distance, meshing contact ratio and mesh stiffness decreases, the amplitude of the harmonic meshing frequency increases, which increases the risk of resonance of the gear system, the center distance compared with the standard value of the tiny change will bring greater incentive engagement impact.
