Abstract：In order to study the static load sharing characteristics of coaxial reversed herringbone gear transmission system,considering the factors such as transmission chain stiffness,alignment errors and manufacturing errors,the torque balance equation of the system is established,the deformation coordination condition of the system is deduced,and the influence of manufacturing and alignment errors on the load sharing performance of the system under single and combined action of gears is analyzed.The analysis shows that when there is a single error in Grade Ⅱ and Grade Ⅲ gears,the load sharing coefficient of the system shows an upward trend with increasing error,and the load sharing performance decreases gradually.When the system is under the comprehensive error,the gear Z8 has the greatest influence on the load sharing performance of the system,and the load sharing coefficient increases by 38.9％.Moreover,as the system speed increases,the load sharing performance gradually decreases.Therefore,In the design and manufacturing process of helicopter main reducer gears,the comprehensive error of gears should be strictly controlled to improve the load sharing performance of the system.
