Abstract
The utility model relates to an improvement of an underwater electric propulsion device of a ship, particularly to an integrated propulsion device of a marine permanent magnetic machine propeller. The integrated propulsion device of the marine permanent magnetic machine propeller comprises an annular stator armature and an annular rotor rotatably arranged in the stator armature, wherein a permanent magnet is fixedly arranged at an external surface of the rotor, propeller blades are uniformly arranged at an internal surface of the rotor along the circumference direction, and ends of the propeller blades are fixedly connected with the internal surface of the rotor. With a transmission shaft, a decelerator and a dynamic sealing device between a motor and the transmission shaft cancelled, the integrated propulsion device substantially reduces manufacturing cost, hull weight and power consumption, occupies little space, and is low in noise and high in work efficiency.
Description
Technical field:
The utility model relates to the boats and ships improvement of electricpropulsion installation under water.
Background technology:
Development along with motor and control technology thereof; Various forms of motors begin to be applied to underwater propeller as power set; But in present electricpropulsion installation, the motor and the screw that produce power are two separate parts, and both pass through decelerator or output shaft coupling together; Cause the electricpropulsion installation axial dimension longer, mechanical loss is big in the course of work, noise is high.And the bind mode of screw basically all is directly to be fixed on the output shaft of propulsion electric machine or decelerator, the time just has to adopt that complex structure, difficulty of processing are big, the dynamic sealing device of sealing effectiveness difference like this in sealing.In addition, screw when snarling, is made motor be in the stall state by underwater obstacle (like fishing net), holds very much the damage that causes electricpropulsion installation.
The utility model content:
To the above-mentioned deficiency of existing in prior technology; The utility model technical problem to be solved is to provide a kind of magneto machine oar peculiar to vessel integrated propulsion plant; It can cancel the dynamic sealing device between power transmission shaft and decelerator and motor and the power transmission shaft, reduces manufacturing cost and hull weight and power consumption greatly, and it is little to take up room; Noise is low, increases work efficiency.
In order to solve the problems of the technologies described above; The integrated propulsion plant of the utility model magneto machine peculiar to vessel oar; The stator armature and the rotating rotor that places the annular in the said stator armature that comprise annular; The outer surface of said rotor is installed with permanent magnet, and the inner surface edge of said rotor circumferentially evenly is equipped with propeller blade, and the taper of said propeller blade is fixedly connected with the inner surface of said rotor.
After adopting such scheme, because propeller blade is fixedly mounted on the inner surface of the rotor of annular through taper, the root of propeller blade is unsettled; Thereby not needing propeller hub, maintaining is more prone to, and it is more unobstructed to flow through the current of propulsion plant; Improved effective push,, just can adjust the rotating speed of propeller blade easily and turn to through improving the size and Orientation of electric current in the stator armature; Thereby change the direction of boats and ships thrust and the speed of a ship or plane of boats and ships easily, the manipulation and the mobility of boats and ships improve greatly, because through rotor direct-driven airscrew blade; Cancel power transmission shaft and decelerator, reduced manufacturing cost greatly, alleviated ship weight; Improve the efficient of boats and ships work,, dynamic sealing device need be installed because propeller blade is fixedly mounted on the inner surface of the rotor of annular; Not only cancelled dynamic sealing device, also reduced manufacturing cost, improved the performance of boats and ships long time continuous workings again from the sealing device aspect.
The permanent magnet of stator armature and rotor carries out static seal with housing respectively;
The inner surface of stator armature is equipped with the stator inner cover;
The outer surface of said permanent magnet is equipped with the rotor outer cover;
Stator armature is sealed to an integral body;
Two ends of rotor is through the rotating inner surface that is fixed on conduit of thrust bearing;
The inner surface of rotor is along three double helix blade sheets circumferentially evenly are installed;
The taper of propeller blade is installed in the inner surface of rotor through screw;
The integrated propulsion plant of the utility model magneto machine peculiar to vessel oar can be applicable to the boats and ships lateral thruster, is installed in the hull tunnel;
The integrated propulsion plant of the utility model magneto machine peculiar to vessel oar can be applicable to the propulsion plant of ship's navigation, is installed in the stern of boats and ships.
