摘要
基于齿轮系统动力学和Lagrange方程建立了人字行星齿轮传动系统的弯-扭-轴耦合动力学计算模型,并进行动态分析,分析结果对人字行星齿轮传动系统的设计有指导意义。模型中将人字齿轮当作2个斜齿轮来处理,考虑了左右端斜齿轮之间的交错角,轮系的弹性耦合和负载惯性。通过计算获得系统均载系数关系曲线,进而分析左右端斜齿轮之间的交错角和耦合扭转刚度对其的影响。分析结果表明:在左右端斜齿轮之间的交错角为π/2时,两端的均载效果最好;同时左右端斜齿轮之间的耦合扭转刚度对均载的影响不大。
Based on the method of gear system dynamics and Lagrange equation,a translational-rotational coupling dynamic model of the herringbone planetary gear sets is built and dynamic analysis is carried out.The analysis results have guiding meanings for the design of herringbone planetary gear transmission system.Herringbone gear is treated as two helical gears in the model,and gear train elastic coupling,load inertia and stagger angle between the left and right helical gears is considered.The load sharing coefficients of the system are obtained through calculation,and the impact of stagger angle and coupling torsional stiffness between the left and the right helical gears on the load sharing characteristic is analyzed.The analysis results show that when stagger angle isπ/2,the load sharing coefficients are the best,and coupling torsional stiffness between the left and the right helical gears has litter influence on the load sharing coefficients.
