The invention discloses a coaxial contra-rotating double-rotor-wing speed reduction transmission structure which comprises an upper gear, a lower gear, a hollow outer rotor wing shaft and an inner rotor wing shaft. The tooth surfaces of the upper face gear and the lower face gear are vertically and coaxially mounted, the hollow outer rotor wing shaft is fixedly connected with the upper face gear in a centering manner, and the inner rotor wing shaft penetrates through the hollow outer rotor wing shaft to be fixedly connected with the lower face gear in a centering manner; thrust bearings are installed at the upper ends of the upper face gear and the lower face gear, and tapered roller bearings are installed at the lower ends of the upper face gear and the lower face gear. One or more powerinput cylindrical gears are arranged between the upper face gear and the lower face gear to be driven in a meshed mode, and each power input cylindrical gear is provided with a self-aligning roller bearing.
