两分支圆柱齿轮分扭传动系统的均载性能

针对两分支圆柱齿轮分扭传动机构,深入剖析了其载荷分布不均衡的原理,通过建立动力学模型,分析了结构参数对均载性能的影响规律,并通过弹性轴结构分扭传动的试验证明了该原理及分析方法的正确性,结果表明:工况条件、两分支扭转刚度、支撑刚度、啮合相位差等因素皆对系统的均载性能具有影响,其中取较小的扭转刚度和较大的支撑刚度,并严格控制第一级齿轮副之间的啮合相位差对均载有利。 

Load sharing performance of two branches split-torque transmission system with cylindrical gears

The principle of non-uniform load distribution in torque-split transmission system of cylindrical gears was analyzed. By establishing the dynamic model of this torque-split transmission system the effects of structure parameters between two sides on the load sharing performance were researched. The test of the split-torque transmission with elastic shaft was carried out, and correctness of the analysis method above was proved.Results showed that the load condition, torsional stiffness, support stiffness and mesh phase differences between two sides had an effect on the load sharing performance of the system, among which smaller torsional stiffness, larger support stiffness and suitable meshing phase difference were beneficial for load sharing.
