Abstract

Provided is a novel small pole difference magnetic field coupling type eccentric magnetic gear pair with transverse magnetic field, which can be widely applied in wind power generation, electric automobiles, ship drive and other industrial transmission fields requiring direct drive. It is characterized in that a magnetic gear pair is formed by a disc-shaped stator magnetic disc on which 2 Ps stator permanent magnets 1 are distributed and a disc-shaped planetary rotor on which 2 Pr planetary rotor permanent magnets 2 are distributed. There is a relatively small difference between the numbers of pole pairs Ps and Pr and the numbers are relatively prime. The permanent magnets are coupled through an air gap transverse magnetic field between the stator and the planetary rotor, and the magnetic gear pair with small pole difference is connected to form an eccentric structure via an eccentric input shaft 3 sheathed inside a second bearing II 12 and a third bearing III 13. The eccentric input shaft 3 drives a planetary wheel 5 in rotation around an axis of rotation. The eccentrically rotating rotor permanent magnets 2 and the stator permanent magnets 1 drive the planetary rotor to rotate around its own axis in the reverse direction by means of magnetic field coupling, and in turn output low-speed self-rotation of the planetary wheel 5 via a hole pin output structure 7.

Description

Novel small pole difference magnetic field coupling type eccentric magnetic gear pair with transverse magnetic field
The secondary technical field of the eccentric magnetic gear of few extreme difference magnetic field coupling-type of new transverse magnetic field
The present invention is a kind of eccentric magnetic gear pair of few extreme difference magnetic field coupling-type of new transverse magnetic field, it is that the variable speed drive that the small torque mechanical energy of high rotating speed is mutually changed with slow-speed of revolution high-torque mechanical energy is realized using magnetic gear drive technology, conventional mechanical change gear transmission speed system can directly be replaced, be widely used in wind-power electricity generation, hydroelectric generation, electric automobile, ships driving and other industrial transmission fields for needing to directly drive.
Say
Background technology
Generally require to realize mutual conversion of the mechanical energy with high rotating speed Low-torque mechanical energy of slow-speed of revolution high-torque in many transmission fields of commercial Application, such as：Wind-power electricity generation and hydroelectric field need extremely low rotating speed and variable wind energy, the potential energy of water are converted into high-revolving generating mechanical kinetic energy, and electric automobile and submarine driving field need the high speed machine power of motor becoming book again
Change that rotating speed is very low into and torque very big mechanical output.By existing conventional designing technique, extremely low rotating speed and high-torque can cause motor volume huge, increase the material consumption of motor per kilowatt number and make it that quantities is huge；For this, existing known common method is that the slow-speed of revolution, the output of high-torque and the requirement of Constant-power speed range are realized by mechanic gear drive technology, the citation form of mechanical gear drive technology does not change for a long time, i.e., be driven by the engagement of the two secondary gear teeth of mechanical gear all the time.This just brings the problem of some can not be eliminated to gear drive, such as mechanical fatigue, frictional dissipation, vibrating noise, although grease lubrication technology can be used, but problem above, which remains unchanged, to be eradicated, cause working service extremely cumbersome, the mechanic gear drive system efficiency of conventional transmission ratio is low, noise is big, poor reliability.The mechanical gear auxiliary driving of fixed conveyor speed ratio causes needs complicated in the multistage of more wide speed range, stepping speed adjusting gear, it is impossible to adapt to the drive technology requirement of increasing variable speed.
China is rare earth permanent-magnetic material most abundant country in the world, and greatly developing the application of rare earth material has the meaning of reality.With the progress of control technology, rare earth permanent-magnetic material has been used widely in electric drive field, all kinds of motor products that rare earth permanent-magnetic material is made, the torque density of its unit volume material transmission is big, efficiency of energy utilization is high and energy consumption is small, shows the huge superiority of its rare earth material.In recent years, with wind-power electricity generation, the growth requirement of the new energy application field such as electric automobile, start to realize on novel magnetic drive technology to mechanically operated technological break-through both at home and abroad, Britain in 2004 and Denmark scholar propose magnetic field modulation technical know-how and its drive mechanism, and the design and model machine checking work of a kind of novel radial magnetic field modulation system magnetic gear are completed from practice, overcome the conventional less shortcoming of permanent magnet gear driving torque, this opens an important research direction and following application field to permanent-magnet material in the application of mechanical transmission fields.This magnetic gear structure based on magnetic field modulation technology has a feature, it is to be modulated using magnetic field modulation principle come the permanent-magnetic field to driving wheel and the different numbers of poles of driven pulley, specifically the method in structure is exactly to have added a magnetic conduction grid iron core with orientation fixed number between driving wheel and driven pulley to lead Magnetic pole, so as to purposefully isolate the drive of two different numbers of poles.
The magnetic gear designed above based on magnetic field modulation technology from theoretical principle to organization plan on there are two big fatal deficiencies：First, theoretically see, the magnetic conduction grid of magnetizing field modulating action pole (tooth) number unshakable in one's determination must is fulfilled for constraints, so as to cause magnetic gear to be all in the working condition of mutual magnetic coupling only less than the permanent magnet of half in any time of operating transmission, there is the permanent magnet pole of more than half to be in idle non-coupled state, i.e. the degree of coupling of rare-earth permanent magnet magnetic pole is lower than 50% in theory；Second, from structure, adding magnetic conduction grid iron core necessarily makes magnetic gear pair be provided with two air gaps, a large amount of magnetomotive force of rare-earth permanent magnet will necessarily be consumed, the permanent magnet flux in coupling operational state is necessarily caused to reduce if magnetic pole thickness is not thickeied, so as to influence transmitted level of torque；3rd, the presence unshakable in one's determination of magnetic conduction grid causes air-gap reluctance to be pulsed with magnetic potential alternation, causes torque cycle to fluctuate, and not only influences transmission accuracy, and the machine torque suffered by magnetic conduction grid iron core is big, and its structural strength is also to influence the principal element in its life-span.So, to reduce the cost of magnetic gear drive technology and further improve the torque of its transmission, the theoretical of magnetic field modulation technology must be just broken through from principle and is constrained, and jump out from structure design the structural constraint of double air gaps.The content of the invention
The problem of existing for existing machinery formula gear transmission technology and two big critical defects of magnetic transmission gear pair currently known, based on magnetic field modulation technology, the purpose of this technology invention are a kind of secondary new construction of the eccentric magnetic gear of the few extreme difference magnetic field coupling-type for providing new transverse magnetic field.The present invention basic conception be, use for reference the principle of the new planet-gear transmission of mechanical gear transmission field, the revolution that the planetary gear of eccentric structure will be inputed to couples the principle attracted with S poles heteropolarity to realize the rotation of planetary gear by permanent-magnet material N poles, planetary gear rotation is exported through export structure, it is achieved thereby that being driven without Mechanical Contact, friction free power speed changing.
