The invention relates to a cycloid paddle which comprises a main shaft, a pull rod, a paddle shaft and at least two paddles, the main shaft can drive the pull rod, the paddle shaft and the paddles to rotate around the axis of the main shaft, the pull rod is fixedly connected with the main shaft, the paddle shaft can freely rotate relative to the pull rod, the pull rod supports the paddle shaft, the paddle shaft is fixedly connected with the paddles, and the number of the paddles is not less than two. Each paddle is provided with an independent transmission system, each transmission system drives the corresponding single paddle to rotate around the axis of the paddle shaft, and the rotation of all the paddles around the axis of the paddle shaft is not correlated; the transmission system comprises two short-distance belt assemblies and a connecting rod, and the two short-distance belt assemblies are connected through the connecting rod. Any single blade of the cycloidal propeller is in the most appropriate angle state in the rotating process, the propelling efficiency is high when the cycloidal propeller serves as a propeller, the efficiency is high when the cycloidal propeller serves as a lift force and thrust composite device, the cycloidal propeller serves as a fixed wing, the lift-drag ratio is high, and the lift force providing efficiency is high.
本发明涉及一种摆线桨,包括主轴、拉杆、桨叶轴和桨叶,主轴能带动拉杆、桨叶轴和桨叶围绕主轴轴线旋转,拉杆与主轴固定连接,桨叶轴相对拉杆可自由转动,拉杆支撑桨叶轴,桨叶轴和桨叶固定连接,桨叶的个数不少于两个,每个桨叶都有一个独立的传动系统,每个传动系统带动相应的单个桨叶围绕所述桨叶轴的轴线旋转,所有桨叶围绕所述桨叶轴轴线的旋转互无关联;传动系统包括两组短距带组件和连杆,两组短距带组件中间通过连杆相连。该摆线桨任一单独桨叶在转动过程中都处于最合适的角度状态,作为推进器时推进效率高,作为升力和推力复合装置时效率高,作固定翼使用,升阻比高,提供升力效率高。
