Abstract

The invention belongs to the technical field of helicopter design, and discloses a face gear transmission coaxial reversing device which comprises an inner rotor shaft, an outer rotor shaft, an upper end face gear, a lower end face gear, a reversing idle wheel and a transmission cylindrical tooth tail wheel. The inner rotor shaft and the outer rotor shaft are connected through a bearing, the upper end face gear is connected with the outer rotor shaft through a spline, and the lower end face gear is connected with the inner rotor shaft through a spline; the reversing idle wheel and the transmission cylindrical tooth tail wheel are located between the upper end face gear and the lower end face gear respectively, the reversing idle wheel is meshed with the upper end face gear and the lower end face gear at the same time, and the transmission cylindrical tooth tail wheel is meshed with the upper end face gear and the lower end face gear at the same time. On the premise that the structure is simple and the space limitation requirement is met, coaxial contra-rotation of the inner rotor shaft and the outer rotor shaft is achieved.

Description

technical field [0001] The invention belongs to the technical field of helicopters, in particular to a coaxial reversing device for face gear transmission. Background technique [0002] Generally, the coaxial reversing device adopts compound planetary counter-rotation transmission and spiral bevel gear counter-rotation transmission, but sometimes it is difficult to realize the above method due to the limitation of space and transmission ratio. [0003] In the helicopter transmission system, the volume and weight of the transmission components directly affect the portability and flexibility of the helicopter. If a compound planetary counter-rotation transmission and a spiral bevel gear counter-rotation transmission are used, the number of parts is large and the quality is heavy. At the same time, the positioning of the casing requires very high. Contents of the invention [0004] The object of the present invention is to provide a coaxial reversing device for face gear tra...
