摘　　要：为了研究由加工产生的对中误差对人字齿轮啮合传动的影响,提高传动的稳定性,根据人字齿轮的结构特点和轮齿几何接触模型,综合考虑齿面间隙、力平衡条件及轴向位移等因素,建立了含对中误差的人字齿轮承载接触分析模型;分析不同对中误差对人字齿轮的轮齿接触和轴向振动的影响,提出了一种利用轴向装配误差与对中误差耦合作用的补偿方法。研究结果表明,对中误差严重降低了人字齿轮传动的稳定性和可靠性,而误差耦合补偿可以降低对中误差引起的偏载和轴向振动,为传动过程的优化提供了新方法,对提高人字齿轮系统的动态特性具有重要意义。In order to study the effect of the symmetry error generated by processing on the herringbone character gear meshing transmission,improve the stability of the transmission,according to the structural characteristics of herringbone gear and gear geometry contact model,consider the tooth surface gap,force equilibrium conditions and axial displacement,the herringbone gear bearing contact analysis model of symmetry error is established.The influence of different symmetry error on the gear contact and axial vibration of a pair of herringbone gear is analyzed,and then a compensation method that uses coupling effect of axial assembling error and symmetry error is put forward.The research result shows that symmetry error seriously reduces the stability and reliability of herringbone gear transmission.The error coupling compensation can lower partial loaded and axial vibration caused by symmetry error which provides new methods for the optimization of transmission process and is of greatly significant to improve the dynamic characteristics of herringbone gear system.
