摘要

为提高分扭传动系统的均载特性

通过构建误差、载荷的分析图

剖析了影响均载性能的机理;考虑支撑刚度、扭转刚度以及齿轮副的时变啮合刚度

采用集中质量法建立了传动系统的动力学模型。通过龙格库塔法求解传动系统动力学模型

计算了传动系统的均载系数;运用正交试验法获得了齿侧间隙、中心距误差对均载特性的影响规律和权重。研究结果表明:齿侧间隙具有相关性

其取值应满足一定的规则;中心距误差无相关性

并车级中心距误差对均载和动载荷系数的影响权重较大。因此

为提高分扭传动构型的均载特性

齿侧间隙、中心距误差需采用参数匹配的设计方法。

Abstract

In order to improve the load sharing characteristics of the split torque drive system

the mechanism of affecting the load sharing performance was analyzed by constructing the analysis diagram of error and load. Considering the support stiffness

the torsional stiffness and time-varying meshing stiffness of the gear pairs

a dynamic model of the transmission system was established by using the lumped mass method. The dynamic model of the transmission system was solved by the Runge Kutta method

and the load sharing coefficient was calculated. The influence law and weight of backlash and center distance error on the load sharing characteristics were obtained by the orthogonal test method. The results showed that the backlash had correlation

and its value should meet certain rules; the center distance error had no correlation

and the center distance error of confluence stage had great influence on the load sharing and dynamic load coefficient. Therefore

in order to improve the load sharing characteristics of the split torque transmission

the design method of parameter matching should be adopted for the backlash and center distance errors.
