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.

    本发明属于直升机设计技术领域,公开了一种面齿轮传动的共轴反转装置,包括:内旋翼轴、外旋翼轴,上端面齿轮、下端面齿轮、换向惰轮及传输出圆柱齿尾轮;其中,内旋翼轴和外旋翼轴之间通过轴承连接,上端面齿轮通过花键与外旋翼轴连接,下端面齿轮通过花键与内旋翼轴连接;换向惰轮及尾传输出圆柱齿轮分别位于上端面齿轮和下端面齿轮之间,换向惰轮与上端面齿轮、下端面齿轮同时啮合,尾传输出圆柱齿轮与上端面齿轮、下端面齿轮同时啮合。在保证结构简单且满足空间限制要求的前提下,实现内、外旋翼轴共轴对转。
