Abstract：With the development of the gear transmission system towards complexity,multiple transmis-sion types and high reliability,it becomes more and more important to assign the reliability of the gear transmis-sion system quickly and accurately.In this study,aiming at the problems of incomplete consideration factors,in-consistent range of changes in different allocation methods for the same parameter,and inconvenient digital soft-ware development in existing reliability allocation methods,an improved advisory group on reliability of electron-ic equipment(AGREE)allocation method is proposed,the scoring allocation method is extended,and the digital characteristics of reliability allocation method are discussed.The basic reliability model and task reliability mod-el of the complex gear transmission system are established,and the traversal algorithm of the automatic reliabili-ty model generation is studied.A digital platform for rapid reliability allocation of fixed axle gear train,planetary gear train and hybrid gear train is developed.Four independent modules,namely input module,calculation mod-ule,result display module and output module,are designed.The accuracy of the calculation results of the soft-ware is verified by comparing with the results of examples.The parametric modeling and the automatic genera-tion of the example report for the reliability allocation of the gear transmission system are realized,and the accu-racy and efficiency of the reliability allocation model are raised.
