The multi-power face gear split flow system is a new type of transmission system, which has the advantages of stable and reliable transmission and strong carrying capacity. And it has great potential in the application of helicopter transmission systems. In this paper, the multi-power face gear split flow system was taken as the research object. Based on the lumped parameter method and Newton’s second law, the translational-torsional dynamic model of the system was established considering the translational vibration and the torsional vibration of the gears, and the meshing force curves and load-sharing coefficient curves were drawn. At the same time, the factors affecting the load-sharing characteristics of the transmission system were studied. The impacts of manufacturing errors, assembly errors, manufacturing error phases, assembly error phases, meshing damping, support stiffness, and the input power on the load-sharing coefficients were analyzed. The research shows that the errors and error phases of spur gears have small impacts on the load-sharing coefficients, while the support stiffness of spur gears has a great impact on the load-sharing coefficients. The errors and error phases of face gears have small impacts on the load-sharing coefficients, while the support stiffness of spur gears has a great impact on the load-sharing coefficients. The load-sharing coefficients increase constantly with the increase in the meshing damping between face gears and spur gears, whereas the load-sharing coefficients decrease constantly with the increase in the input power.

多动力端面齿轮分流系统均载特性分析研究

多动力端面齿轮分流系统是一种新型传动系统,具有传动平稳可靠、承载能力强等优点。并且在直升机传动系统的应用中具有很大的潜力。本文以多动力端面齿轮分流系统为研究对象。基于集中参数法和牛顿第二定律,建立了考虑齿轮平移振动和扭转振动的系统的平移-扭转动力学模型,绘制了啮合力曲线和均载系数曲线。同时研究了影响输电系统均载特性的因素。制造错误、装配错误、制造错误阶段、装配错误阶段的影响,分析了啮合阻尼、支撑刚度和输入功率对负载分担系数的影响。研究表明,正齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。平面齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。均载系数随平面齿轮与正齿轮啮合阻尼的增大而不断增大,而均载系数随输入功率的增大而不断减小。研究表明,正齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。平面齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。均载系数随平面齿轮与正齿轮啮合阻尼的增大而不断增大,而均载系数随输入功率的增大而不断减小。研究表明,正齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。平面齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。均载系数随平面齿轮与正齿轮啮合阻尼的增大而不断增大,而均载系数随输入功率的增大而不断减小。平面齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。均载系数随平面齿轮与正齿轮啮合阻尼的增大而不断增大,而均载系数随输入功率的增大而不断减小。平面齿轮的误差和误差相位对均载系数的影响较小,而直齿轮的支承刚度对均载系数的影响较大。均载系数随平面齿轮与正齿轮啮合阻尼的增大而不断增大,而均载系数随输入功率的增大而不断减小。
