Description
Technical field:
The utility model is a kind of sucked type permanent magnet clutch, belongs to the permanent magnetism new application.
Background technology:
Human activity in production relies on pump mostly, and the fault-free of pump is moved the height that has determined production efficiency continuously.And pump miscellaneous all relies on dissimilar contact positive coupling transferring power, realizes the increment demand of human material progress and cultural and ideological progress.Along with the development of high energy product, high-coercive force rare earth permanent magnetic material, established material base for realizing permanent magnetism noncontact transmission.
Permanent magnetism noncontact transmission the earliest starts from the conveying of the easy contaminated-fluid of poisonous and harmful, because permanent magnet can the noncontact transmitting torque, people isolate fully with original machine output shaft and fluid pump power shaft that non-magnet material will arrange permanent magnet clutch, realized the totally-enclosed conveying, step a most successful step for the mankind explore the permanent magnet transmission technology, and set up the instructive model for follow-up developments.
The large-scale open-ocean operations naval vessel of military industry field, because wave acutely rises and falls, moderate finite deformation can appear in hull, cause pump connecting axial organ failure rate high, directly affect fighting efficiency, therefore U.S. Johns restrains the permanent magnet clutch that takes the lead in using the noncontact transmission on Tanis number and the USS Nimitz aircraft carrier, has obtained good effect, fries the application upsurge that has played the permanent magnet transmission technology.
Carry at military project high-tech and poisonous and harmful and easy pollution medium and to be widely used under the drive of permanent magnet clutch, to reliability with exempt to pollute all kinds of gearings of industry such as the chemical industry of having relatively high expectations, medical and health, food, semiconductor, vacuum field, oil, electric power, constantly update original rigid attachment kind of drive, replace the permanent magnet clutch of noncontact transmission, promote the raising of permanent magnet transmission technological progress and benefit, be called as the boost motor of the next time industrial revolution.
Permanent magnet clutch divides synchronous mode, eddy current type, hysteresis, reluctance type four classes by operation principle.
The synchronous permanent magnetic shaft coupling is to arrange alternately permanent magnet by N, S polar-symmetric on two half a couplers, leans on the push-and-pull action power of permanent magnet with the synchronous speed transmitting torque between the two.Advantage be simple in structure, reliability and durability, transmitting torque is large, transmission efficiency is high.Shortcoming is to exceed the quata to decide torsion coupling to skid easily, causes the high temperature demagnetization.
The eddy-current permanent magnetic shaft coupling changes the synchronous mode internal rotor into copper ring, when rotating, external rotor produces rotating magnetic field, copper ring on the internal rotor produces induced current because of cutting magnetic line, this faradic magnetic field and outer rotor permanent magnet magnetic field interaction make internal rotor rotate and transmitting torque with external rotor.Advantage be internal rotor without permanent magnetic material, can in the liquid of sealing, rotate, adapt to the higher medium of delivery temperature.Shortcoming is that rotor copper ring must could be rotated by cutting magnetic line, has the slip loss, is usually used in the undemanding transmission of rotating speed requirement.
The hysteresis permanent magnet clutch utilizes soft magnetic material to be in the course of the work the characteristic of remagnetization, itself and permanent magnetic material combination are made permanent magnetism-magnetic hysteresis shaft coupling, the two suction obviously reduces than the suction between permanent magnet, but change easily the relative rotation between the two, be usually used in becoming the connection of moment of torsion.
Reluctance type permanent magnet clutch external rotor is with radial is identical synchronously, and internal rotor soft magnetic material salient pole utilizes the internal rotor with salient pole suction of external rotor magnet to drive the internal rotor rotation, and transmitting torque is obviously not enough, is used for the small magnetic transmission device.
Although above-mentioned all kinds of permanent magnet clutch respectively has characteristics, also has common drawback:
The one, industrial shaft coupling requirement moment of torsion is larger, permanent magnet clutch will satisfy the moment of torsion design must use more expensive Nd-Fe-B rare earth permanent magnetic material, finished product permanent magnet clutch sale price of market mostly is greatly 10-100 times of common positive coupling, has limited applying of permanent magnet clutch;
The 2nd, rare earth permanent-magnetic material has the characteristic of high energy product, on-the-spot dismounting difficulty, and work is wasted time and energy;
The 3rd, axial force and radial load impact are larger to driving and driven gearing harm.Above-mentioned three drawbacks have affected the large-scale promotion of permanent magnet clutch, demand developing a kind of permanent magnet clutch of brand new urgently, capture above-mentioned Three Difficult Issues, and the innovation and the large-scale promotion that promote the permanent magnet transmission technology are popularized.
For realizing the breakthrough innovation of permanent magnet transmission technology, the technical staff has carried out unremitting effort, optimizes magnetic circuit, and preferred material improves structure, makes the permanent magnet transmission technology improve constantly development, but is difficult to all the time the innovation of making a breakthrough property.The heuristic process of invention and success often only have one step away, why permanent magnet transmission technology in the past is difficult to breakthrough innovation, key is that its technical thought is conceived to the static mindset of " synchronously, eddy current, magnetic hysteresis, magnetic resistance ", if technology path is based on " stack ", " release " dynamic thinking mode, technical barrier will be readily solved.
Summary of the invention:
The utility model is enlightened by permanent magnetic chuck, utilize the principle of continuity of magnetic flux and magnetic field superposition principle, become a plurality of magnetic to be the permanent magnet clutch magnetic Circuit Design, relative motion by magnetic system, stack or the counteracting of magnetic field intensity on the realization work magnetic pole strength, thereby reach high pulling torque output and without the purpose of magnetic dismounting, and solve at one stroke and make the difficult problem that expensive, axial force and radial load suppress, start the milestone of permanent magnet transmission, obtain economies of scale and social benefit convenient to disassembly, safe and reliable to operation without magnetic, that use low-consumption high-efficiency, easy maintenance easily to go.
