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.
