The invention provides a differential device used on an aircraft transmission line system and the aircraft transmission line system, and belongs to the technical field of aircraft transmission. A first straight tooth gear pair adjusts the transmission ratio of the whole transmission line system; the second straight tooth gear pair adjusts the polarity of the transmission line system and the distance between the axis of the backup power source and the transmission line system. The first straight tooth gear pair and the second straight tooth gear pair achieve various transmission modes of the aircraft transmission line system under the control action of the planetary differential mechanism. Compared with a WW type planetary differential mechanism and an NN type planetary differential mechanism, the NGW type planetary differential mechanism is simple in structure, the number of planetary gears is small, and the weight of the structure is easily reduced. And compared with a bevel gear differential mechanism, the installation and debugging links are simple, the machining cost of the bevel straight teeth is lower, and the overall economical efficiency is better. The NGW type planetary differential mechanism has the advantages of being compact in structure, better in machining and assembling manufacturability and light in weight.

    本发明提供一种飞机传动线系上使用的差速装置及飞机传动线系,属于飞机传动技术领域,本发明中第一直齿齿轮副调整整个传动线系的传动比;第二直齿齿轮副调整传动线系的极性及备份动力源轴线与传动线系的距离;第一直齿齿轮副、第二直齿齿轮副在行星差速机构的控制作用下实现飞机传动线系的多种传动模式。与WW、NN型行星差速机构相比,本发明的NGW型行星差速机构的结构简单,行星轮数量少,易于结构减重。与锥齿轮差速机构相比,安装调试环节简单,锥直齿加工成本更低,整体经济性更优。本发明的NGW型行星差速机构具有结构紧凑、加工装配工艺性更优、重量轻的优点。
