According to the driving reversing device of the manta ray imitating aircraft, the input shaft rotates, the two sides of the input gear conduct rotation through the gear transmission structures respectively, reversing of transmission rotation on one side is achieved through the reversing gear, incomplete tooth design is adopted for the two gears meshed with the output gear, and therefore the driving reversing device of the manta ray imitating aircraft is achieved. The gear tooth area and the smooth gear-tooth-free area on the outer edge of the gear are arranged at intervals, the two incomplete gears on the two sides and the output gear are located in the meshing area, it is guaranteed that when one of the two incomplete gears is meshed with the output gear, the gear-tooth-free area of the other incomplete gear is exactly adjacent to the output gear, and therefore forward-direction rotation interval output of the two incomplete gears and forward-direction rotation interval output of the two incomplete gears are guaranteed. Through tooth number matching of all the gear structures and tooth number matching of incomplete teeth, it can be guaranteed that the rotating speed of forward output rotation and the rotating speed of reverse output rotation are equal, the duration time or interval time of forward rotation and reverse rotation is consistent, the structure is simple, cost is low, stability is high, it can be guaranteed that the meshing time intervals of the two sides are equal, and running transition is smooth.
本发明提供了一种仿蝠鲼航行器的驱动换向装置,输入轴旋转运动、输入齿轮两侧分别通过齿轮传动结构传导旋转,并通过换向齿轮实现一侧传动旋转的反向,在与输出齿轮啮合的两个齿轮均采用不完全齿设计,即齿轮外缘的轮齿区域和光滑无轮齿区域间隔设置,而两侧的两个不完全齿轮均与输出齿轮位于啮合区域,且保证二者其一与输出齿轮啮合时,另一者恰好是无轮齿区域与输出齿轮相邻,从而保证了二者的正方向旋转间隔输出,通过各个齿轮结构的齿数配合及不完全齿的齿数配合可以保证不论正向还是反向输出旋转的转速相等且正向旋转与反向旋转的持续时间或间隔时间一致,其结构简单成本低、稳定性高,能保证两侧啮合的时间间隔相等,其运转过渡平滑。
