Description
Technical field
The present invention is a kind of few extreme difference magnetic field coupling-type magnetic transmission eccentric gear pair of Novel radial magnetic field, that a kind of magnetic gear drive technology that utilizes is realized the variable speed drive that the low moment mechanical energy of high rotating speed and slow-speed of revolution high-torque mechanical energy are changed mutually, can directly replace conventional mechanical change gear transmission speed system, be widely used in the industrial transmission field that wind power generation, hydroelectric power generation, electric automobile, ships driving and other needs directly drive.
Background technology
Many transmission fields in commercial Application often need to realize the mechanical energy of slow-speed of revolution high-torque and the mutual conversion that high rotating speed hangs down moment mechanical energy, such as: wind power generation and hydroelectric power generation field need to become high-revolving generating mechanical kinetic energy with the utmost point slow-speed of revolution and variable wind energy, the potential energy converting and energy of water, electric automobile and submarine drive the field needs again high speed machine power conversion with drive motors to become the very low and very large mechanical output of moment of rotating speed.By existing conventional designing technique, the utmost point slow-speed of revolution and high-torque can make motor volume huge, increase the material consumption of motor per kilowatt number and make quantities huge; For this reason, existing known common method is to realize the output of the slow-speed of revolution, high-torque and the requirement of Constant-power speed range by the mechanic gear drive technology, the citation form of mechanical gear drive technology does not change for a long time, is all the time namely 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 drive, as mechanical fatigue, frictional dissipation, vibrating noise etc., although can adopt the grease lubrication technology, but 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 drive system efficient of conventional transmission ratio is lower, noise is larger, reliability is very poor, and whole drive system volume is large.The mechanical type gear pair transmission of fixed conveyor speed ratio makes and need at more multistage, the stepping speed adjusting gear complex structure of wide speed range, can't adapt to increasing infinite variable speed drive technology requirement.
China is rare earth permanent-magnetic material the abundantest country in the world, and the application of greatly developing rare earth material has the meaning of reality to China.Progress along with control technology, 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 unit volume material transmits is large, efficiency of energy utilization is high and energy consumption is little, demonstrates the huge superiority of its rare earth material.
In recent years, growth requirement along with new forms of energy applications such as wind power generation, electric automobiles, begin both at home and abroad to realize mechanically operated technological break-through on the novel magnetic drive technology, the Britain engineer had completed a kind of design work of Novel radial magnetic field magnetic gear from the concrete practice of theoretical and model machine in 2004, overcome the less shortcoming of permanent magnet gear 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 magnetic material; This case inventor also proposed first respectively in before multinomial patent application case (201110142746.2,201120177813.X, 201110170001.7,201120210494.8 and 201120327120.4) Novel transverse to the magnetic transmission gear pair new construction of magnetic field structure and oblique magnetic field structure with and concrete application structure.Set forth above have a common feature about the various new construction schemes of magnetic gear, all namely to adopt the magnetic field modulation principle that the permanent-magnetic field of the different numbers of poles of driving wheel and driven pulley is modulated, concrete method structurally is exactly to have added a magnetic conduction grid iron core with directed fixed number to do leading pole between driving wheel and driven pulley, thereby on purpose isolates the drive of two different numbers of poles.But, there are two large fatal deficiencies on from the theoretical principle to the organization plan in this magnetic gear that designs based on the magnetic field modulation technology: first, see theoretically, the magnetic conduction grid of the magnetizing field modulating action utmost point (tooth) number unshakable in one's determination must satisfy constraints, thereby cause magnetic gear all only to be in the operating state of mutual magnetic Field Coupling less than half permanent magnet in any time of running transmission, have permanent magnet pole over half to be in idle non-coupled state, namely the utilance of rare-earth permanent magnet is in theory just lower than 50%; Second, on 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, according to the demagnetization characteristic of Rare-Earth Magnetic material as can be known: if do not thicken magnetic pole thickness the permanent magnet magnetic flux that must cause being in the coupling operating state reduces, thus the torque that impact is transmitted.This two large defective causes the amount of the expensive rare earth material that the magnetic gear based on the magnetic field modulation technology consumes relatively large.So, reduce the cost of magnetic gear drive technology, just must break through from principle the theory constraint of magnetic field modulation technology, and jump out the structural constraint of two air gaps from structural design.
Summary of the invention
The problem that exists for existing machinery formula gear transmission technology and at present known, based on two large critical defects of the magnetic transmission gear pair of magnetic field modulation technology, the purpose that present technique is invented is to provide a kind of few extreme difference magnetic field coupling-type magnetic transmission eccentric gear pair new construction of Novel radial magnetic field.Basic conception of the present invention is, use for reference the principle of the novel planet-gear transmission of mechanical gear transmission field, the principle that the revolution that inputs to the planet rotor of eccentric structure is attracted mutually by the permanent magnetic material N utmost point and S utmost point heteropolarity realizes the rotation of planet rotor, through the pin-hole type export structure, the planet rotor rotation is exported, thereby realized machinery-free contact, the transmission of friction free power speed changing.
