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.
