Abstract：The load sharing design is a crucial technology that leverages the configuration advantages of the herringbone power split gear train.To improve the load sharing characteristics of the herringbone power split gear train,a static model that accounts for support stiffness,torsional stiffness,and gear mesh stiffness is con-struceted.The main factors affecting load sharing characteristics under the influence of errors and varying loads are analyzed.By using Romax software,a finite element simulation model consideres structural features like floating components,flexible elements,and herringbone gears,as well as errors and transmission system defor-mations,and load sharing coefficients are determined.The isolated impact of factors such as eccentricity error,synchronization angle,elastic shaft torsional stiffness,and herringbone gear symmetry error on load sharing char-acteristics is examined.Furthermore,utilizing the orthogonal experimental method,the interaction patterns and significance levels of these factors on load sharing characteristics are uncovered.The results show that synchro-nization angle and herringbone gear symmetry error significantly affect load sharing characteristics,with elastic shaft torsional stiffness being the next most influential factor,and eccentricity error having a noticeable impact.To achieve superior load sharing characteristics,it is recommended to use lower elastic shaft torsional stiffness in design,and employ parameter-matching design methods for the connection between the transmission shaft and gear keyway to reduce synchronization angles.
