摘　　要：以通用机床变速箱啮合齿轮组为主要研究对象,针对齿轮组啮合过程时变应力不稳定且超过材料许用应力问题,提出了啮合齿轮组齿形修正的优化设计方法。并对该齿轮组进行瞬态动力学分析,得到啮合齿轮组的应力分布,降低了该通用机床变速箱齿轮组啮合最大时变应力,进而保证了变速箱齿轮组啮合过程的稳定性和可靠性。This paper takes the gear group of universal machine tool gearbox as the main research object,aiming at the problem that the time-varying stress occurred in the process of gear group meshing is unstable and beyond material’s al-lowable stress,putting forward an optimization design method of profile modification for meshing gear group.And transient dynamic analysis is carried out about the gear group to find out the stress distribution of gear group,as a result,the meshing maximum time-varying stress of the gear group in the universal machine tool gearbox is reduced,thereby the stability and reliability in gear group engagement process of gearbox is guaranteed.
