摘要
分析了同轴面齿轮分扭传动在某型直升机主减速器中的应用,并借助于等效位移与等效刚度的定义,揭示了同轴面齿轮分扭传动不均载机理。应用解析的方法,建立了同轴面齿轮分扭传动的均载计算模型。基于均载计算模型,采用数值仿真计算的方法,初步探索了系统参数对同轴面齿轮分扭传动均载性能的影响规律。分析结果表明,当输入齿轮采用大弹性支撑时,系统均载性能对齿侧间隙低敏感。
The application of the concentric torque-split face gear transmission on the main gearbox of he licopter is analyzed.Based on the definition of equivalent displacement and equivalent stiffness,the mechanism of the uneven load sharing of the concentric torque-split face gear transmission is revealed.The load sharing cal culation model of the concentric torque-split face gear transmission is established by an analytic method.With the help of numerical method,the influences of the factors of the system on the load sharing behaviors are pre liminarily explored.The results show that the load sharing performance of the system is less sensitive to the backlash when the support stiffness of the input pinion is low.
