Description
Technical field
The present invention is a kind of few extreme difference magnetic field induction magnetic transmission eccentric gear pair of radial magnetic field, it is a kind of variable speed drive utilizing magnetic gear drive technology mutually to change to realize high rotating speed Low-torque mechanical energy and slow-speed of revolution high-torque mechanical energy, directly can replace conventional mechanical change gear transmission speed system, be widely used in wind-power electricity generation, hydroelectric power, electric vehicle, ships drive and other needs the industrial transmission field of Direct driver.
Background technique
Often need to realize the mechanical energy of slow-speed of revolution high-torque and the mutual conversion of high rotating speed Low-torque mechanical energy at many transmission fields of commercial Application, such as: wind-power electricity generation and hydroelectric field need the pole slow-speed of revolution and the potential energy converting and energy of variable wind energy, water becomes high-revolving generating mechanical kinetic energy, electric vehicle and submarine drive field to need again the high speed machine power conversion of drive motor to become rotating speed very low and mechanical output that moment is very large.By the designing technique of existing routine, the pole slow-speed of revolution and high-torque can make motor volume huge, increase the materials consumption of motor per kilowatt number and make engineering work load huge; For this reason, existing known common method is to realize the slow-speed of revolution, the output of high-torque and the requirement of Constant-power speed range by mechanic gear drive technology, the citation form of mechanical gear drive technology does not change for a long time, is namely all the time to rely on the engagement of two gear teeth of mechanical gear pair to carry out transmission.This just brings some not eliminable problems to gear transmission, as mechanical fatigue, frictional loss, vibrating noise etc., although grease lubrication technology can be adopted, but above problem still cannot be eradicated, cause working service extremely loaded down with trivial details, and the theoretical efficiency of mechanical gear transmission at most also can only reach 85%, and the mechanic gear drive system efficiency of conventional transmission ratio is lower, noise is larger, reliability is very poor, and whole transmission system volume is large.The mechanical gear auxiliary driving of fixed conveyor speed ratio makes to need multistage, stepping speed regulating mechanism complex structure at more wide speed range, cannot adapt to increasing infinite variable speed drive technology requirement.
China is the country that rare earth permanent-magnetic material is the abundantest in the world, and the application greatly developing rare earth material has the meaning of reality to China.Along with the progress of control technique, rare earth permanent-magnetic material is used widely in electric drive field, all kinds of motor products that rare earth permanent-magnetic material is made, and the torque density that its per unit volume material transmits is large, efficiency of energy utilization is high and energy consumption is little, demonstrates the superiority that its rare earth material is huge.
In recent years, along with the growth requirement of the new energy such as wind-power electricity generation, electric vehicle application, start both at home and abroad to realize mechanically operated technological break-through on novel magnetic drive technology, within 2004, Britain engineer completes a kind of design work of Novel radial magnetic field magnetic gear from concrete practice that is theoretical and model machine, overcome the shortcoming that permanent magnetic gear wheel driving torque is less in the past, this opens an important research direction and following application in the application of mechanical transmission fields to permanent-magnet material; Inventor also proposes Novel transverse respectively first to the magnetic transmission gear pair new structure of magnetic field structure and oblique magnetic field structure and its embody rule structure in multinomial patent application case (201110142746.2,201120177813.X, 201110170001.7,201120210494.8 and 201120327120.4) before.Set forth above have a common feature about the various new structure scheme of magnetic gear, namely be all adopt the magnetic field modulation principle permanent-magnetic field to the different numbers of poles of driving wheel and follower to modulate, concrete method is structurally exactly between driving wheel and follower, added a magnetic conduction grid iron core with directed fixed number do leading pole, thus on purpose isolates the drive wheel of two different numbers of poles.But, this magnetic gear designed based on magnetic field modulation technology from theoretical principle to organization plan on there are two fatal greatly deficiencies: first, see theoretically, magnetic conduction grid pole (tooth) number unshakable in one's determination of magnetizing field modulating action must meet constraint conditio, thus cause magnetic gear to be all only in the working state of mutual magnetic Field Coupling less than the permanent magnet of half in any time of running transmission, have permanent magnet pole over half to be in idle non-coupled state, namely the utilization ratio of rare-earth permanent magnet is in theory just lower than 50%; Second, from structure, adding magnetic conduction grid iron core must make magnetic gear pair be provided with two air gaps, a large amount of magnetomotive force of rare-earth permanent magnet must be consumed, demagnetization characteristic according to Rare-Earth Magnetic material: if do not thicken magnetic pole thickness, must cause the permanent magnet flux being in coupling operational state to reduce, thus affect the torque transmitted.The amount of the expensive rare earth material that this two large defect causes the magnetic gear based on magnetic field modulation technology to consume is relatively large.So, the cost of magnetic gear drive technology be reduced, just must break through the theory constraint of magnetic field modulation technology from principle, and jump out the structural constraint of two air gap from structural design.
In the recent period, inventor it is also proposed a kind of few range magnetic transmission eccentric disc shaped gear pair (201110355864.1 and 201120444409.4) of Novel radial magnetic field, this magnetic gear pair is that the permanent-magnetic field of the two kinds of different numbers of poles utilized in two transmission wheel sets interacts, intercouple the object reaching carry-over moment and gear, in fact this is a kind of concept being similar to the synchronous driving speed change in synchronous machine magnetic field, up to now, all also nobody proposed to utilize the induction type principle of AC induction motor to improve working principle and the embody rule structure of few range magnetic transmission eccentric gear pair both at home and abroad, and the invention of such technology and structure exactly has important practical significance for the consumption reducing expensive rare earth permanent-magnetic material.
