功率分流齿轮传动系统均载性能的影响因素研究

功率分流传动系统具有承载能力强、传动比大、结构紧凑等优点，已被成功应用于航空、船舶等领域。确保载荷平均分配于各支路上是该系统设计应用时需考虑的关键问题之一。本文通过齿轮系统动力学模型对某功率分流传动系统的均载问题进行了研究。在动力学建模中综合考虑了齿轮副的齿面误差、啮合间隙、弹性变形以及其他影响均载性能的因素，并进行了深入的参数敏感度分析；根据计算结果，提出了可以提高传动系统均载能力的若干方式。

Influencing Factors of Load-Sharing in Split Path Gear Transmission System

The split path transmission system is applied in the fields of aero and nautical engineering successfully, due to its advantages including high load capacity, large transmission ratio and compact structures. To ensure the balance of load-sharing on each path is the key issue of split path transmission system. In the paper, the load-sharing characteristics of split path transmission system which is equipped on helicopter is investigated via gear system dynamics. The errors of gear profiles, clearances, elastic deformations as well as other factors are taken into account in the model. Several feasible solutions are proposed to enhance the load-sharing performance based on a series of in-depth parametric studies.
