Description
Technical field
The present invention is that a kind of few extreme difference magnetic field induction magnetic transmission eccentricity gear of radial magnetic field is secondary; Be that a kind of magnetic gear drive technology that utilizes is realized the variable speed drive that low moment mechanical energy of high rotating speed and the big moment mechanical energy of the slow-speed of revolution are changed each other; Can directly replace conventional mechanical change gear transmission speed system, be widely used in the industrial transmission field that wind-power electricity generation, hydroelectric power, electric vehicle, ships driving and other needs directly drive.
Background technique
Often need realize the mutual conversion of the mechanical energy and the low moment mechanical energy of high rotating speed of the big moment of the slow-speed of revolution at many transmission fields of commercial Application; Need become high-revolving generating to use mechanical kinetic energy the utmost point slow-speed of revolution and variable wind energy, the potential energy converting and energy of water such as: wind-power electricity generation and hydroelectric power field, electric vehicle and submarine drive the field need become the high speed machine Power Conversion of drive motor the very low and very big mechanical output of moment of rotating speed again.By existing conventional designing technique, the utmost point slow-speed of revolution can make that with big moment motor volume is huge, increases the materials consumption of motor per kilowatt number and makes engineering work load huge; For this reason; Existing known common method is to realize the slow-speed of revolution, the output of big moment and the requirement of constant-power speed regulation scope by the mechanic gear drive technology; The citation form of mechanical gear drive technology does not change for a long time, promptly is all the time to rely on the engagement of two gear teeth of mechanical type gear pair to carry out transmission.This has just brought some problems that can not eliminate to gear transmission; Like mechanical fatigue, frictional loss, vibrating noise etc., although can adopt the grease lubrication technology, above problem still can't be eradicated; Cause working service extremely loaded down with trivial details; And the gear-driven theoretical efficiency of mechanical type at most also can only reach 85%, and the mechanic gear system transmission efficiency of conventional transmission ratio is lower, noise is bigger, reliability is very poor, and the whole drive system volume is big.The mechanical type gear pair transmission of fixed conveyor speed ratio makes and need can't adapt to increasing infinite variable speed drive technology requirement at more multistage, the stepping speed regulating mechanism complex structure of wide speed range.
China is the abundantest country of rare earth permanent-magnetic material in the world, and the application of greatly developing rare earth material has realistic meanings to China.Progress along with control technique; Rare earth permanent-magnetic material drives the field at electricity and is used widely, 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 big; Efficiency of energy utilization height and energy consumption is little demonstrates the huge superiority of its rare earth material.
In recent years; Growth requirement along with new energy applications such as wind-power electricity generation, electric vehicles; Begin both at home and abroad on the novel magnetic drive technology, to realize to mechanically operated technological break-through; Britain engineers in 2004 have accomplished a kind of design work of novel radial magnetic field magnetic gear from the concrete practice of theoretical and model machine; Overcome the less shortcoming of permanent magnetic gear wheel driving torque in the past, this has opened up an important research direction and following application in the application of mechanical transmission fields for permanent-magnet material; This case inventor before multinomial patent application case (201110142746.2,201120177813.X, 201110170001.7,201120210494.8 and 201120327120.4) in novel transverse magnetic field structure and oblique magnetic field structure also proposed respectively first magnetic driving gear pair new structure with and concrete application structure.Set forth above all have a common feature about the various new structure schemes of magnetic gear; Promptly all be to adopt the magnetic field modulation principle to come the permanent-magnetic field of the different numbers of poles of driving wheel and follower is modulated; Concrete method structurally is exactly between driving wheel and follower, to have added a magnetic conduction grid iron core with directed fixed number to do leading pole, thereby on purpose isolates the drive wheel of two different numbers of poles.But; This based on magnetic field modulation technology and there are two big fatal deficiencies on from the theoretical principle to the organization plan in the magnetic gear of design: first; See theoretically; The magnetic conduction grid of the magnetizing field modulating action utmost point (tooth) number unshakable in one's determination must satisfy constraint conditio; Thereby cause magnetic gear all only to be in the working state that the phase mutual magnetic field is coupled less than half the permanent magnet in any time of running transmission, have permanent magnet pole over half to be in idle non-coupled state, promptly the utilization ratio of rare-earth permanent magnet just is lower than 50% in theory; Second; See from structure; Adding magnetic conduction grid iron core must make the magnetic gear pair have two air gaps; Must consume a large amount of magnetomotive force of rare-earth permanent magnet, can know according to the demagnetization characteristic of Rare-Earth Magnetic material: if do not thicken magnetic pole thickness then the permanent magnet magnetic flux that must cause being in the coupling working state reduces, thus the torque that influence is transmitted.This two big defective causes based on the amount of the expensive rare earth material that magnetic gear consumed of magnetic field modulation technology relatively big.So, reduce the cost of magnetic gear drive technology, just must break through the theory constraint of magnetic field modulation technology from principle, and jump out the structural constraint of two air gaps from structural design.
In the recent period; This case inventor has also proposed a kind of few extreme difference magnetic transmission eccentric disc generating gear secondary (201110355864.1 and 201120444409.4) of novel radial magnetic field; This magnetic gear pair is that the permanent-magnetic field that utilizes two kinds of different numbers of poles on two transmission wheel sets interacts, intercoupling reaches the purpose of carry-over moment and speed change transmission; In fact this is a kind of notion that is similar to the synchronous drive speed change in synchronous machine magnetic field; Up to now both at home and abroad all also nobody proposed to utilize the induction type principle of AC induction motor to improve secondary working principle of few extreme difference magnetic transmission eccentricity gear and concrete application structure, and the invention of such technology and structure exactly has important practical significance for the consumption of the rare earth permanent-magnetic material of minimizing costliness.
