The invention discloses a propeller of an unmanned underwater vehicle. The propeller of the unmanned underwater vehicle comprises a propeller hub, propeller blades, a front end cover, a rear end cover, a connecting shaft, propeller hub magnetic steel and connecting shaft magnetic steel, wherein the propeller hub is installed on the connecting shaft through a front end cover and a rear end cover, aplurality of blades are arranged on the outer circumferential face of the propeller hub, and propeller hub magnetic steel is fixedly connected to the inner circumferential face of the propeller hub;the connecting shaft is used for connecting an output shaft of a propulsion motor, and the peripheral surface is fixedly connected with connecting shaft magnetic steel in one-to-one correspondence with the propeller hub magnetic steel; the propeller hub and the connecting shaft are arranged at intervals, and a radial gap is formed between the propeller hub magnetic steel and the connecting shaft magnetic steel which correspond to each other; the propeller hub magnetic steel and the connecting shaft magnetic steel are located in an annular cavity defined by the propeller hub, the front end cover, the rear end cover and the connecting shaft, and polarity of the propeller hub magnetic steel is the same as that of the connecting shaft magnetic steel. The propeller can avoid the accidents thatthe propulsion motor is locked or even burnt due to winding of the fishing net.

    本发明公开了一种水下无人航行器螺旋桨,该水下无人航行器螺旋桨包括桨毂、桨叶、前端盖、后端盖、连接轴、桨毂磁钢以及连接轴磁钢;桨毂通过前端盖和后端盖安装于连接轴,桨毂的外周面设置有多个桨叶、且内周面固定连接有桨毂磁钢;连接轴用于连接推进电机的输出轴,外周面固定连接有与桨毂磁钢一一对应的连接轴磁钢;桨毂与连接轴之间间隔设置,相互对应的桨毂磁钢和连接轴磁钢之间具有径向间隙;桨毂磁钢和连接轴磁钢位于由桨毂、前端盖、后端盖以及连接轴围成的环形空腔内,并且桨毂磁钢的极性与连接轴磁钢的极性相同。上述螺旋桨能够避免因渔网缠绕而造成推进电机堵转甚至烧毁事故的发生。
