Abstract The dynamic responses and load sharing features of a two-path split torque gear transmission system are investigated in this study. The possible combinations of shaft angles to ensure the gear pairs work properly are determined considering the adjacency relationship, concentric relationship, geometrical conditions and installation conditions. A dynamic model of the system considering time-varying mesh stiffness, backlash, static transmission error, stagger angle excitations and gyroscopic effects of gear body and flexible shaft is proposed. The natural characteristics of the system including natural frequencies and critical speeds are obtained. The influences of the shaft angle, asymmetric transmission error excitations and right-to-left stagger angle of double-helical gear teeth on the dynamic transmission error responses and load sharing features of the two-path split torque gear transmission system are investigated. Several references to determine the system parameters to improve the transmission property and load sharing performance of the system are provided based on the numerical simulation results.

两路分流扭矩传递系统非线性动力学及均载特性研究

摘要 本研究研究了双路分流式齿轮传动系统的动态响应和负载分担特性。考虑相邻关系、同心关系、几何条件和安装条件，确定确保齿轮副正常工作的轴角度的可能组合。提出了一种考虑时变啮合刚度、侧隙、静态传动误差、交错角激励以及齿轮体和软轴陀螺效应的系统动力学模型。获得系统的固有特性，包括固有频率和临界速度。轴角的影响，研究了双斜齿轮齿的非对称传动误差激励和从右到左的交错角对双路分流式齿轮传动系统的动态传动误差响应和负载分担特性的影响。根据数值模拟结果，为确定系统参数以提高系统的传输性能和均载性能提供了若干参考。
