The invention discloses an oppositely-rotating shaft-less rim-driven propeller which is provided with a guide tube component, wherein a stator winding, a front rotor component and a rear rotor component are arranged in the inner cavity of a shell; rotor rings in the two rotor components form a conical matching pair in an axial direction, and the polarities of permanent magnets embedded into the outer walls of the two rotor rings are opposite; and after the stator winding is electrified, the stator winding and the permanent magnets simultaneously form magnetic fields with opposite magnetic properties, namely that one stator drives two rotors to rotate to form a dual-rotor annular motor, thereby driving a front paddle and a rear paddle to rotate oppositely so as to generate thrust for pushing a ship to move forwards. The propeller disclosed by the invention has the advantages of small occupied space, high propulsion efficiency, large thrust, good transverse stability, small vibration and the like, and is particularly suitable for propelling of military boats and ships and modern civil ships as well as positioning of offshore platforms.
