Abstract
The invention discloses a propeller for coaxial reversal ship, which comprises the following parts: hollow shaft on the motor chassis, counterclockwise stator coil and clockwise stator coil at two ends of hollow shaft, leading line of stator coil to the motor chassis through hollow shaft, wherein one end of counterclockwise external rotor and clockwise external rotor is assembled at two ends of hollow shaft through water lubricating bearing; the counterclockwise propeller and clockwise propeller are assembled on the counterclockwise external rotor and clockwise external rotor. The invention contains two groups of rotor to produce two equal opposite forces, which cancels respective opposite torque to improve the precision of underwater machine.
Description
(1) technical field
What the present invention relates to is a kind of propulsion plant of boats and ships.Specifically a kind of marine propulsion that directly acts on the water surface.
(2) background technology
Existing marine propulsion system all is that single-blade promotes, and water makes boats and ships produce yawing under sail to the reactive torque that screw produces, equipment such as the submarine of underwater navigation, torpedo, the unmanned device of diving especially, and the influence of this reactive torque is more obvious.In order to correct yawing, the method that adopts has two kinds usually.A kind of is that change rudder angle, change power push away methods such as water angle.This method can consume part power; Another is to adopt two oars to changeing the power set of arranging, this structure has increased head resistance, has consumed part power.
Obviously, above-mentioned technology can not satisfy the requirement of modern ships propulsion system fully.
(3) summary of the invention
The object of the present invention is to provide a kind of problem that can solve reaction torque, reduce head resistance, improve the thruster for coaxial reverse thruster ship of dynamic efficiency.
The object of the present invention is achieved like this: it comprises the hollow shaft that is installed on the motor base, the two ends of hollow shaft are fixed with counterclockwise stator coil and clockwise stator coil, the lead-out wire of stator coil is drawn out to motor base by hollow shaft, be covered with counterclockwise external rotor and clockwise external rotor respectively outside stator coil and the clockwise stator coil counterclockwise, one end of counterclockwise external rotor and clockwise external rotor is installed in the two ends of hollow shaft respectively by water lubriucated bearing, be separately installed with counterclockwise screw and counterclockwise screw on external rotor and the clockwise external rotor counterclockwise.
The present invention can also comprise some features like this:
1, in the end of hollow shaft radome fairing is set.
2, described counterclockwise stator coil and clockwise stator coil respectively by stator core, be wrapped in that 6202 resin waterproof of enamelled wire on the stator core and cast form, described counterclockwise stator coil is that stator core hot pressing is on hollow shaft with the two ends that clockwise stator coil is fixed on hollow shaft.
3, described counterclockwise external rotor and clockwise external rotor are respectively by forming with the permanent magnet that becomes even number in being bonded in housing with the metal housing of high permeability.
The present invention has comprised two group rotors, the opposite force opposite sign but equal magnitude that two group rotors produce.The reaction torque of having cancelled out each other and having produced has separately solved the influence of reaction torque to the attitude of ship.The invention has the advantages that:
The method that tradition solves reaction torque is to utilize hydroplane or utilize the method that reverse flow deflector is installed to overcome reaction torque to have consumed a part of power.The present invention utilizes the form of dual rotation propeller, has well solved reaction torque the influence of boats and ships has been improved efficiency of motor.Be particularly useful for underwater hiding-machine, the power source of equipment such as torpedo.The screw and the motor outer rotor of native system are the integrated design, and can be hung on the volume that afterbody has reduced power packages greatly outward, the latent device of microminiature have been saved the space of a large amount of preciousnesses by it.The stator coil of motor is by hollow shaft, and the lead-out wire of two motors is drawn holder one end at motor, helps the installation of this system.Two groups of rotating speed of motor can be controlled respectively, to reach the balance of moment of torsion.Install respectively before and after two screws, the opposite pitch rotation direction of paddle for oppositely to commentaries on classics, back oar traditional method of indicating the pronunciation of a Chinese character bow oar reverse the efficient that current have improved screw.
The present invention the time can not produce reaction torque in work, can improve a lot to the control precision under water of the device of diving.Being specially adapted to power at the device of diving advance, the dive technical fields such as attitude adjustment, hydrolocation of device uses.
