Abstract
The invention provides an underwater hollow hub-free propeller, which comprises a motor shell, a stator coil, a stator silicon-steel sheet, a rotor permanent magnet, a rotor, a screw propeller and a ceramic bearing. The stator coil is wound on the stator silicon-steel sheet, the stator coil wound on the stator silicon-steel sheet is arranged at the center of the motor shell, the rotor has a hollow annular structure, split poles of the rotor permanent magnet are fixed on the rotor to form a hollow structural rotor, the screw propeller is fixed inside the hollow rotor, and the screw propeller, the rotor and the rotor permanent magnet form a whole; and the rotor is fixed in the motor shell through the ceramic bearing. When blades rotate, induced resistance and cavity bubble phenomenon are not generated so as to greatly improve the efficiency of the screw propeller. Moreover, because the diameter of a motor is enlarged, the pole number of the motor is increased and the torque of the motor is improved, the underwater hollow hub-free propeller is particularly suitable for working in an environment with large water depth and large density; and because the motor and the screw propeller of the underwater propeller have an integral hollow structure, the underwater hollow hub-free propeller can be easily arranged on a ship hull.
Description
(1) technical field
What the present invention relates to is a kind of propulsion plant of boats and ships, particularly a kind of underwater propulsion unit.
(2) background technology
Along with the progress of China's Ocean Development Technology and the development of boats and ships cause, China also greatly improves the requirement of boats and ships underwater propeller, traditional underwater propeller is that motor shaft is installed the screw that has propeller hub, current flow into from motor the place ahead during the rotation of driven by motor screw, motor produces head resistance to blade, the screw blade tip produces induced drag and cavity phenomenon when rotated, has reduced propeller efficiency; In addition, because motor output shaft is longer under the traditional water, screw also can produce radially vibrations when rotated, also can reduce whole angle of rake efficient.
Number of patent application is " a kind of marine propeller " in 02151202.7 the patent document, the described cylinder that is equipped with on the external diameter of screw prevents water generates centrifugal force and produces Radial Flow, reduce the problem of operating efficiency, also can reach the effect that reduces induced drag.But this form still provides the rotation rotatory force by line shaft by propeller hub.Can't eliminate the head resistance of propeller hub and hull.The present invention has cancelled the propeller hub structure by at the sleeve rotor madial wall blade being installed, reduced head resistance, the permanent magnet of even number is installed in the outside of sleeve rotor, form the rotor of motor, stator lumps together by ceramic bearing and rotor set, forms a kind of not only dynamic but also the marine propulsion that advances blade and do not have propeller hub is arranged.Avoided propeller hub hull head resistance, this device can be directly installed on the bottom of hull, do not needed line shaft and stretch out, simplified the structure of hull, reduced cost from hull interior.
Number of patent application is " internal propeller " in the patent document of 95104172.X, described a kind of inside spin slurry form, this kind propelling form have many a bit as the propulsive efficiency height, noise is little, vibrations are little, compact conformation etc.Therefore but its center still has wheel hub, fails to solve the problem of twining of preventing.A kind of propeller form of not having wheel hub of the present invention design has well solved the problem of twining of preventing, and because stopping of no wheel hub can improve propulsive efficiency widely.
(3) summary of the invention
The object of the present invention is to provide a kind of high pulling torque, high efficiency can not produce the underwater hollow hub-free propeller of induced drag and cavity phenomenon.
The object of the present invention is achieved like this:
Its composition comprises motor housing, stator coil, stator silicon steel sheet, rotor permanent magnet, rotor, screw and ceramic bearing, stator coil is wrapped on the stator silicon steel sheet, be wrapped in stator coil on the stator silicon steel sheet and be contained in the center of motor housing, rotor is the hollow annular structure, the rotor permanent magnet split pole is fixed on the rotor, the rotor of formation hollow-core construction, screw is fixed on sleeve rotor inside, screw, rotor and rotor permanent magnet are formed as a whole, and rotor is fixed in the motor housing by ceramic bearing.
The present invention can also comprise:
1, in the both sides of motor housing kuppe is installed.
2, described ceramic bearing has two, lays respectively at the both sides of motor housing.
3, stator coil, stator silicon steel sheet and motor housing are integral by 6202 resin-bonded.6202 resins are withstand voltage to be 95Mpa, with the motor of this insulation resin operate as normal in the environment of 5000m fully under water.
The invention has the advantages that motor and hydrodynamic force oar are organically combined, strengthened the diameter of motor, the rotor design of motor is hollow annular form, screw is installed on the drum inwall of rotor, make screw become as a whole with the rotor bucket, screw motor itself when rotated can not produce head resistance to screw, screw is installed on the inwall of rotor, equal on the slurry point, end plate to be installed, can not produce the efficient that induced drag and cavity phenomenon have improved screw greatly during the paddle rotation.Because the increasing diameter that has strengthened motor adds the moment of torsion that the number of poles of motor has improved motor, be particluarly suitable for working in the environment under the big density of the big depth of water in addition,, be easy to be installed on the hull because the motor and the screw of this underwater propeller are overall structure.Be applicable to the various waters surface, underwater hiding-machine, equipments such as torpedo.
(4) description of drawings
Fig. 1 is a perspective view of the present invention;
Fig. 2 is a planar structure schematic diagram of the present invention;
Fig. 3 is a cutaway view of the present invention.
(5) embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1 to Fig. 3, the composition of underwater hollow hub-free propeller comprises motor electronic shell 1, end cap 2, and ceramic angular contact bearing 3, rotor 4, propeller blade 5 solidifies crust 6, stator coil 7.
Motor housing 1, stator coil 7 is wrapped on the silicon steel sheet of stator motor stator casing 1, motor housing 1 center of then it being packed into, rotor 4 is designed to the hollow annular structure, and the rotor permanent magnet split pole is fixed on the rotor 4, forms the rotor of hollow-core construction, propeller blade 5 is fixed on sleeve rotor 4 inside, make propeller blade 5, rotor 4 and form as a wholely, two ceramic angular contact bearings 3 are fixed on rotor 4 in the motor, can lead at motor both sides dress radome fairing according to application need.Stator coil 7 adopt 6202 resins carry out water-proofing treatment to solidifying shell 6, superhard resin solidifies and makes motor housing form hard capsul to bear high undersea hydrostatic pressures crossing vacuum environment.
During this underwater propeller work, propeller blade 5 is installed on the inwall of rotor 4, is equivalent on the slurry point end plate is installed, and can not produce the efficient that induced drag and cavity phenomenon have improved propeller blade 5 greatly during propeller blade 5 rotations; Because the increasing diameter that has strengthened motor adds the moment of torsion that the number of poles of motor has improved motor, the form that has changed screw has improved angle of rake efficient.
