Technical field
The utility model relates to magnetic coupling technical field, particularly relates to a kind of permanent magnetic coupling position limiting structure.
Background technology
Determining square type magnetic coupling is realize 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, during as large fan load for mine, owing to considering the variation of axial position in High Rotation Speed, this air gap generally will retain 5 ~ 8 millimeters.But in actual motion, axial endplay from motor side or load end 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.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.The device damage caused therefrom is at present 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.Coupler structure between two conductor disc is located at for permanent magnetic disk, ensures that axial air-gap is stable important especially.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of permanent magnetic coupling position limiting structure avoiding producing between described conductor disc and permanent magnetic disk direct mechanical friction.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of permanent magnetic coupling position limiting structure, 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, described p-m rotor dish is provided with permanent magnet, described conductor rotor dish is provided with conductor plate, fixing air gap is maintained between described permanent magnet and described conductor plate, it is characterized in that, the inner side of master end conductor disc and slave end conductor disc is arranged with guide vane end stop, rotatablely on described guide vane end stop be embedded with ball, spacing slideway is provided with in the both sides of described p-m rotor dish and described guide vane end stop opposite position place, fixed interval (FI) is maintained between described spacing slideway and described ball, described fixing air gap is greater than described fixed interval (FI).
The beneficial effects of the utility model are: owing to adopting ball and spacing slideway structure, when there is motor or load axial endplay, being first the spacing slideway of ball contact, limiting axial dipole field, avoiding the mechanical friction of p-m rotor dish and described conductor plate.And ball and spacing slideway are rolling friction, high temperature can not be produced as the sliding friction of p-m rotor dish and described conductor plate.Therefore the useful life of equipment can greatly be improved.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described guide vane end stop is provided with ball recess, and described ball is inlaid in described ball recess, and the outer end of described ball exceeds the plane of described guide vane end stop, and described ball is copper or nylon material.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt copper or nylon material to be conducive to protecting conductor plate.
Further, described ball is evenly equipped with at least three.
Adopt the beneficial effect of above-mentioned further scheme to be that three can form a uniform stress surface, when p-m rotor dish diameter is larger, more configuration can be adopted.
