摘要：Introduction Based on the characteristics of the helicopter main reduction gearbox, and combined with the advantages of face gear and cylindrical gear power dividing, a new configuration of helicopter main gearbox with twice split paths is proposed. A bending-torsional coupled dynamic model of the system is developed through the lumped parameter method, and the influence of stiffness, damping and backlash are considered. Methods The dynamic equation is solved by Runge-Kutta method, and the load sharing and the dynamic load coefficients are obtained, as well as their variation with the backlash. Results Results show that with the increase of the backlash, the load-sharing coefficient decreases, the dynamic load coefficient increases, but the other drive stages are almost unaffected. Compared with split torque stages and power confluence stages, the load sharing and dynamic load coefficient of power input stages are the most sensitive to the backlash of the power input stage, and the appropriate increase of the backlash can effectively improve the dynamic properties. Conclusion Therefore, in order to obtain better dynamic performance, it is necessary to allocate the backlash reasonably.
