The invention discloses a shaftless rim propeller, and relates to the technical field of propulsion, the shaftless rim propeller comprises a guide pipe and a rotor, the guide pipe is provided with a cylindrical shell and a containing space located on the inner side of the shell, a multi-magnetic-pole stator is arranged in the shell of the guide pipe, the rotor is located in the containing space and corresponds to the inner side of the multi-magnetic-pole stator, and the rotor is located in the shell of the guide pipe and corresponds to the inner side of the multi-magnetic-pole stator. The rotor and the guide pipe are coaxially arranged, and propeller blades are installed at the position, facing the center of the rotor, of the rotor. A shell of the guide pipe is provided with a groove, so that a gap structure surrounding the rotor is formed between the shell and the rotor, and the gap structure is provided with a groove so that part of water flow can flow along the groove when the rotor rotates. The shaftless rim propeller provided by the invention can reduce the friction loss at the gap and improve the propelling performance of the shaftless rim propeller, and has the advantages of simple structure, no complex mechanical device interaction and convenience in maintenance and management.
