摘要

针对双路功率分流系统的载荷均匀分布问题

建立了该系统的静力学模型

并根据系统构成功率流动闭环的特点

推导出扭转角变形协调条件

将该条件联立力矩平衡条件和弹性支承条件

计算出了各齿轮副传递的扭矩

得到系统的均载系数.从静力学角度分析了各构件安装误差和均载特性的关系

并分析了间隙浮动对均载特性的影响.结果表明:齿轮2存在安装误差为0.03mm的情况下

间隙量为0.8mm即可满足基本构件浮动

得到均载系数为1.0038

间隙浮动有利于提高均载性能.对比实验和理论分析的结果

同一误差条件下

功率分配分别为53.88%和53.50%

从而验证了该方法的正确性.

Abstract

In order to implement the uniform load distribution of the gear train with dual power spliting

a pseudo-static model was built firstly.And then

according to the system power flow closed-loop feature

the torsional angle deformation compatibility conditions were deduced

the moment equilibrium conditions and elastic support conditions was established to calculate each gear pair transmission torque

and finally the system load sharing coefficient was obtained.Next

the relationship of the installation error and system load sharing characteristics was analyzed in the static research

and the floating pinion based on clearance floating played an important role in the system load sharing. The results show that the clearance of 0.8mm could meet the pinion to floating under the influence of the gear 2 with installation error of 0.03mm

obtain the load sharing coefficient of 1.0038

the floating pinion can improve the load sharing characteristics. Through theoretical data compared with the experimental data

in the same error conditions

power distribution is respectively 53.88% and 53.50%

which verifies the correctness of the method proposed.
