The invention discloses a high-thrust rim propeller. The high-thrust rim propeller comprises a rotating shaft, a shell, a motor stator and a motor rotor, the rotating shaft is of a hollow and trumpet-shaped structure and is movably mounted in the end covers on the two sides of the shell through bearings; a sealing assembly is arranged outside the bearing; a propeller is fixedly mounted on a large-end inner ring of the rotating shaft, and a motor rotor is fixedly mounted on a small-end outer ring of the rotating shaft; the motor stator is fixedly mounted on the shell and corresponds to the rotor; a rectifying piece is arranged at the rear end of the propeller and is fixed on the flow guide cover through a connecting rod penetrating through a central channel of the propeller; and the flow guide cover is fixedly arranged on the shell. According to the high-thrust rim propeller, the sealing performance is good, the structural characteristics of the pipeline and the propeller are combined, and the Venturi effect is utilized, so that the contradiction between a high-power driving device and a limited mounting space in the rim propeller and the utilization problem of vortex energy in the pipeline are well solved, the small size of the rim propeller is ensured, and the thrust and the propulsive efficiency are greatly improved.

    本发明公开了一种大推力轮缘推进器,包括有转轴、壳体、电机定子及电机转子;转轴呈中空、喇叭状结构,通过轴承活动安装在壳体的两侧的端盖中;轴承外侧设有密封组件;转轴大端部内环固定安装有螺旋桨,小端部外环固定安装有电机转子;电机定子固定安装在壳体上,与所述转子相对应;所述螺旋桨后端设有整流片,整流片通过贯穿螺旋桨中心通道的连杆固定在导流罩上;导流罩固定安装在壳体上。本发明提供了一种密封性能好,且结合了其管道及螺旋桨的结构特点,并利用了文丘里效应,极好地解决了轮缘推进器中大功率驱动装置与有限的安装空间之间的矛盾及管道中涡动能量的利用问题,在保证轮缘推进器小体积的同时,大大提高了其推力及推进效率。
