Description
Technical field
The invention belongs to electromechanical integration technology area, particularly relate to a kind of magnetic coupling underwater propeller.
Background technology
The principle of work of underwater propeller is: the convert rotational motion exported by motor by the rotation of propeller blade is axial thrust.The integral arrangement of tradition underwater propeller is: adopt commercially available electrical motor, sometimes in order to actual needs also can install retarder additional as actuating device before electrical motor, and actuating device is placed in sealed module, utilize the output shaft carrying screws of actuating device to rotate and produce thrust.The matter of utmost importance that tradition underwater propeller faces is sealing problem.The sealing means of current main flow has: mechanical seal and magnetic coupling seal two kinds of forms, minisub adopts contacting mechanical seal mostly both at home and abroad at present, in such an embodiment, turning cylinder contacts with standstill seal circle, if the pressure between turning cylinder and seal ring is too small, leakage can be produced, if pressure is excessive, friction force can be caused to increase, consume more mechanical horsepowers.Traditional magnetic coupling sealing means can solve the insecure problem of contacting mechanical seal, but its structure still adopts above-mentioned traditional arrangement form, the spatial volume that this arrangement form takies is larger, for the underwater hiding-machine that integrated level is higher, the space that propelling unit volume takies greatly underwater hiding-machine is large, directly can cause that the plot ratio of underwater hiding-machine reduces, the reduction of lift-launch ability.
Summary of the invention
The present invention provides a kind of magnetic coupling underwater propeller for solving in known technology the technical matters that exists, and this propeller structure is compact, volume is little, efficiency is high, stable and reliable for performance.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is: a kind of magnetic coupling underwater propeller, comprises non-metal waterproof case and the end cap affixed with it; Sealed chamber is formed in the central authorities of described housing, registration mast is formed at the bottom of the interior barrel of described sealed chamber, described registration mast is fixed with motor stator, in described sealed chamber, driving circuit is installed, the packaging body of hard waterproof gasket cement is formed at the oral area of described sealed chamber, described motor stator and described driving circuit are sealed in described sealed chamber by the packaging body of described hard waterproof gasket cement, and the coil lead of described motor stator extends to outside described sealed chamber through the packaging body of described hard waterproof gasket cement; Described end cap is formed rotor support holes, the cylindrical of described rotor support holes and described sealed chamber is supported with the rotor with described motor stator adaptation, described rotor is connected with screw propeller, and the boss diameter ratio of described screw propeller is 0.59 ~ 0.68; The medial surface of described non-metal waterproof case adopts curved-surface structure, and described non-metal waterproof case and described end cap form the mozzle of described screw propeller; Described end cap and described non-metal waterproof case are all connected with streamlined reefer housing.
Described rotor adopts deep groove ball bearing and the supporting of ultra-thin bearing, and described deep groove ball bearing is arranged in described rotor support holes, and described ultra-thin bearing is arranged on the cylindrical of described sealed chamber.
The opening described rotor support holes dorsad of described sealed chamber.
Described housing and described end cap are threaded.
The advantage that the present invention has and good effect are: be fixed on rotor by screw propeller, and expand boss diameter ratio, shorten angle of rake axial dimension, on the basis of satisfied use needs, reduce diameter of propeller, and then reduce angle of rake volume.Compared with traditional underwater propeller, the overall volume of this magnetic coupling underwater propeller reduces about 50%, for underwater hiding-machines such as the ROV under water that integration degree is higher, this magnetic coupling underwater propeller greatly can be saved and take up room, and improves plot ratio and the ability of lift-launch of underwater hiding-machine.In addition, the present invention adopt be looped around around screw propeller non-metal waterproof case and end cap formed mozzle, non-metal waterproof case and end cap adopt thin-wall construction, during propelling unit work, motor stator carries out heat exchange by very thin sealed chamber and water, the good heat dissipation effect of motor stator, thus the heat that sealed chamber inner stator coil is operationally produced can shed to greatest extent, and then obtain than power higher in atmosphere, enable propelling unit export larger thrust.Angle of rake stable and reliable working performance can be made simultaneously.Further, in the present invention, for bear hydraulic pressure annular seal space in be fixed with motor stator, non-hollow structure, therefore this propelling unit can bear larger hydraulic pressure.And the present invention is without the need to doing special sealing again.In sum, structure of the present invention is simple, and space utilization is abundant, and efficiency is high, and reliability is high, and cost is low, is particularly suitable for sub aqua sport platform and selects.
