Abstract
The present invention relates to a magnetic coupler which comprises a conductor rotor disc and a permanent magnetic rotor disc. The conductor rotor disc comprises a driving side conductor disc and a driven side conductor disc which are fixedly connected through a bolt. The permanent magnetic rotor disc is arranged between the two conductor discs. Fixed air gaps are maintained between the permanent magnetic rotor disc and the conductor discs. The permanent magnetic rotor disc is fixedly provided with a load flange. The magnetic coupler is characterized in that the outer circle of the load flange is sleeved by a bearing which comprises an inner ring and an outer ring. The inner ring of the bearing and the outer circle of the load flange are in interference fit, and the outer ring of the bearing is connected to the outer side of the driven side conductor disc through a connection piece. The magnetic coupler has the advantages that the air gap constancy between the conductor discs and the permanent magnetic disc can be maintained.
Description
Technical field
The present invention relates to technical field of power transmission, particularly relate to a kind of magnetic coupling.
Background technology
Magnetic coupling realizes the torque transfer of motor to load by the air gap between conductor disc and permanent magnetic disk, and because its reliability is high, device structure is simple, and the advantages such as failure rate is low, are widely used in mine and factory.In order to ensure higher efficiency of transmission, the air gap between described conductor disc and permanent magnetic disk should be accomplished less in theory, in fact because the reason of processing and mounting technology aspect generally also must ensure certain air gap, to avoid the generation mechanical friction that is in operation.For the coupler that power is larger, as the 400KW fans load for mine, owing to considering the displacement in High Rotation Speed, this air gap generally will retain 5 ~ 8 millimeters.But in actual motion, axial endplay from motor side is inevitable, especially in after powering several seconds, the axle play of motor can reach maximum, and due to startup stage conductor disc and permanent magnetic disk between rotating speed with the biggest gap, if mechanical friction occurs for both, permanent magnetic disk will be caused immediately to damage because of frictional heating or reduce transmission performance.The device damage caused therefrom is relatively more frequent, and field service is very inconvenient, and stopping production may be caused to result in greater loss, and such large equipment beams back factory's maintenance, then more delay use.If for this reason that the air-gap setting between conductor disc and permanent magnetic disk is too large, although can avoid friction, the energy transmission loss caused can be very large, is also very worthless scheme.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of and can keep the magnetic coupling that between conductor disc and permanent magnetic disk, air gap is constant.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of magnetic coupling, comprise conductor rotor dish and p-m rotor dish, described conductor rotor dish comprises the master end conductor disc and slave end conductor disc that are bolted to connection, described p-m rotor dish is located between two described conductor disc, fixing air gap is maintained between described p-m rotor dish and described conductor disc, described p-m rotor dish is fixed with load flange, it is characterized in that, the cylindrical of described load flange is set with bearing, described bearing comprises inner ring and outer ring, the inner ring of described bearing and the cylindrical interference fit of described load flange, the outer ring of described bearing is connected by the outside of connector with described slave end conductor disc.
Operation principle of the present invention is such: be fixedly connected with p-m rotor dish by conductor rotor dish owing to adopting connector, when there is axial endplay in motor side, can axial force be passed on bearing axle, like this or prevent the play of motor shaft, or drive the synchronous play of bearing axle, but total energy ensures that between conductor disc and permanent magnetic disk, air gap is constant.Because conductor disc and permanent magnetic disk run medium velocity gap not quite normal, only there is the slippage of tens turns, therefore bearing used will have permanent useful life.
The invention has the beneficial effects as follows: one is that to maintain air gap between conductor disc and permanent magnetic disk constant, completely avoid the coupler fault caused due to load or axial movement of motor, the useful life of coupler is improved greatly; Two is owing to not considering above-mentionedly to alter axle factor, thus air gap between conductor disc and permanent magnetic disk can be made to keep best, improves efficiency of transmission.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the cylindrical of described load flange is provided with for bearings mounted shoulder.
The beneficial effect of above-mentioned further scheme is adopted to be that the installation location that shoulder is convenient to bearing is set.
Further, described bearing is radial thrust bearing.
The beneficial effect of above-mentioned further scheme is adopted to be that this class bearing effectively can bear axial force.
Further, described connector comprises vertical fillet and level connection joint limit, and described level connection joint limit is provided with flight, is also provided with bearing holder (housing, cover) between described bearing outer ring and described connector, described bearing holder (housing, cover) is fixedly set on described bearing outer ring, and described bearing holder (housing, cover) is provided with multiple fixing hole.Described connector is connected with described slave end conductor disc screw.
Multiple pad is also provided with between described connector and described slave end conductor disc.
The beneficial effect of above-mentioned further scheme is adopted to be adopt flight, fixing air gap can be regulated easily.Fixed range can also be regulated by pad according to different air gap requirements.
Further, described slave end conductor disc is provided with radial dovetail groove, and the joint face of described connector and described slave end conductor disc is provided with the coattail board suitable with described dovetail groove, and described coattail board is slidably inserted in described dovetail groove.
The beneficial effect of above-mentioned further scheme is adopted to be, because an advantage of magnetic coupling is the coaxial error that driving shaft and driven shaft can allow several millimeters, therefore this connector is connected with radially sliding of slave end conductor disc, can eliminate the additional stress impact that this disalignment produces.
