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.

    本发明公开了一种共轴对转双旋翼减速传动构型,包括上方面齿轮、下方面齿轮、空心外旋翼轴和内旋翼轴,上方面齿轮和下方面齿轮齿面对齿面垂直共轴安装,空心外旋翼轴与上方面齿轮对中紧固联接,内旋翼轴穿过空心外旋翼轴与下方面齿轮对中紧固联接;上方面齿轮和下方面齿轮的上端均安装有推力轴承,且其下端均安装有圆锥滚子轴承;一个或若干个功率输入圆柱齿轮置于上方面齿轮和下方面齿轮之间啮合驱动,且每个功率输入圆柱齿轮都安装有调心滚子轴承。
