Description
Technical field
The present invention relates to a kind of screw propeller.Specifically, be blade is distributed on permanent magnet machine rotor cover inner periphery to shaftless screw oar, be applicable on marine propeller.
Background technology
All know in shipbuilding industry, the propelling unit that current boats and ships use is all traditional propeller.The screw propeller of this traditional propeller is made up of oar axle and the blade be fixed on oar axle.This screw propeller needs motor as power, and the output shaft of described motor is connected with the input shaft of gear case, and the output shaft of gear case is connected with the oar axle of screw propeller.During work, drive the blade on oar axle and oar axle to rotate by motor by gear case, thus produce the propelling that forward thrust realizes boats and ships.Because this screw propeller is made up of oar axle and the blade be fixed on oar axle, needs again motor special, gear case to drive during work, make complicated structure, driving efficiency low.Again because this screw propeller is made up of oar axle and the blade be fixed on oar axle, need again motor special, gear case to drive during work, make volume comparatively large, occupy installing space many.Because this screw propeller is made up of oar axle and the blade be fixed on oar axle, need again motor special, gear case to drive during work, all mechanical drive between rotor axis of electric and motor housing, between oar axle and axle bed, all need bearing and lubricating oil, make drive noise large, be unfavorable for operator ' s health.And lubricating oil is easily revealed, pollution can be brought to water environment.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of magneto-electric machine propeller screw oar peculiar to vessel.This screw propeller, structure is simple, and volume is little, occupies installing space few, and noise is little, is conducive to operator ' s health, can not bring pollution to water environment.
The problems referred to above that the present invention will solve are realized by following technical scheme:
Magneto-electric machine propeller screw oar peculiar to vessel of the present invention comprises blade, be characterized in also comprising magneto-electric machine, described magneto-electric machine contains stator sleeve and rotor cover, have stator coil and permanent magnet forever respectively in stator sleeve inner circle and on rotor cover cylindrical, described blade be distributed on inner periphery that described rotor overlaps to.
Take such scheme, have the following advantages:
As can be seen from the above scheme, because the present invention contains magneto-electric machine, described magneto-electric machine contains stator sleeve and rotor cover, has stator coil and permanent magnet forever respectively in stator sleeve inner circle and on rotor cover cylindrical, described blade be distributed on inner periphery that described rotor overlaps to.By magneto-electric machine and permanent magnet machine rotor overlap inner periphery to blade form shaftless screw oar.During work, by being energized to magneto-electric machine, the stator be made up of the stator coil on stator sleeve and inner circle thereof can produce alternating magnetic field, make to be overlapped by rotor and excircle to the rotor that forms of permanent magnet forever produce rotary torque, and rotor driven cover inner periphery to blade rotate together, realize the propelling to boats and ships.Compared with the traditional propeller in background technology, do not need motor special and motor output shaft, gear case and oar axle, only lean on magneto-electric machine and overlap with rotor the blade that inner circle is integrative-structure, just can realize the propelling of boats and ships, simplify the structure, improve driving efficiency.Again due to the present invention only by magneto-electric machine with to overlap inner circle with the rotor of magneto-electric machine be that the parts such as the blade of integrative-structure form, structure is simple, makes the especially axial small volume of volume, occupies installing space less.Due to the present invention only by magneto-electric machine with to overlap inner circle with rotor be that the parts such as the blade of integrative-structure form, do not need bearing and lubricating oil, thus reduce drive noise, be not only conducive to the health of operating personal, and avoid lubricating oil and easily reveal the pollution that water environment is brought.
