面齿轮分汇流系统动力学均载特性研究

Analytical investigation on load sharing characteristics for face gear split flow system

以面齿轮分汇流系统为研究对象,基于牛顿第二定律,考虑齿轮的平移振动和扭转振动,利用集中参数法建立该系统的平移-扭转动力学模型,研究啮合力和均载系数随时间的变化曲线,分析齿轮的偏心误差、支撑刚度、输入功率、输入转速对均载系数的影响.研究结果表明该系统的啮合力和均载系数分别在1.0×10~4~1.7×10~4 N/m和0.85~1.15内周期性变化.

The face gear split flow system was taken as the research object in this paper.Based on the Newton’s second law,the translational-torsional dynamic model of the system was established by the lumped parameter method 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 effects of eccentricity error,support stiffness,input power and input speed on load sharing coefficients were analyzed.The research shows that the meshing forces of the system vary periodically from 1.0×10~4~1.7×10~4 N/m,and the load sharing coefficients fluctuate within the range of 0.85~1.15.
