Problems solved by technology

[0002] The existing marine propeller is subject to central axis resistance in water, so that the ship will encounter wave-making resistance and friction between dynamic and static water during navigation, as well as noise caused by wave-making resistance, so a shaftless propeller is needed. Reduce the wave-making resistance in the shafted screw propulsion, and form the combined force of suction and spray to promote the speed of the ship's water navigation

Embodiment Construction

[0026] In order to better understand the purpose, structure and function of the present invention, a further detailed description of the marine shaftless electric propulsion of the present invention is given below with reference to the accompanying drawings.

[0027] like Figure 1-9 As shown in the figure, the marine shaftless electric propeller of the present invention includes a stator, the stator is tubular, and a tubular rotor is arranged inside; a support bearing is arranged between the stator and the rotor, so that the rotor rotates smoothly in the stator; The stator is provided with stator windings, and the rotor is provided with rotor windings to form a shaftless motor, which provides rotational power and reduces the central axis resistance of the marine propeller in the water; The rotation of the rotor realizes the drainage movement.

[0028] like Figure 1-9 As shown, further, the blades are arranged at an angle of 30 degrees on the inner wall of the rotor, and th...

Abstract

A shaftless electric propeller for a ship comprises a stator, the stator is tubular, a tubular rotor is arranged in the stator, and the shaftless electric propeller is characterized in that a supporting bearing is arranged between the stator and the rotor, so that the rotor smoothly rotates in the stator; a stator winding is arranged on the stator, and a rotor winding is arranged on the rotor, so that a shaftless motor is formed; the inner wall of the rotor is provided with paddles, and the paddles achieve drainage movement along with rotation of the rotor. The blades are arranged in a spiral line mode, uninterrupted uniform drainage movement is completed in a relay mode, compared with blades arranged in the same plane, the water drainage amount of the blades is increased, and the improvement pushing force of the propeller is improved. By arranging the inner cylinder, the advancing blades, the retreating blades, the advancing blade grooves and the retreating blade grooves, output and stop of power of the propeller and change of the power direction are achieved, wherein the advancing blade grooves and the retreating blade grooves are matched.

Description

technical field [0001] The invention belongs to the technical field of marine propellers, and in particular relates to a marine shaftless electric propeller. Background technique [0002] The existing marine propellers are subject to the central axis resistance in the water, which causes the wave-making resistance and the friction between the dynamic and static water that the ship will encounter during navigation, as well as the noise caused by the wave-making resistance. Therefore, a shaftless propeller is needed. Reduce the wave-making resistance in the axial screw propulsion, and form a suction-jet combined force to promote the speed of the ship's water navigation. And the existing propellers are evenly distributed around the central axis and rotate on a plane. During the process of rotating and draining, the water is only drained on the same plane to overcome the viscous resistance in the water, and cannot form a relay drainage. Increase the displacement and improve the...
