Abstract
A magnetic levitation mainly resolves the problem that friction of a traditional bearing is high in working process and comprises a bearing seat and a sleeve. The magnetic levitation is characterized in that the bearing seat is a magnetic bearing seat, the sleeve is a magnetic rotating part which can rotate in the magnetic seat, and a part of the magnetic rotating part arranged in the magnetic seat has identical polarity with the magnetic seat. Compared with the prior art, the magnetic levitation bearing overcomes a defect that friction of the traditional bearing is high in working, greatly reduces noise and vibration of mechanical equipment, facilitates stable running of equipment, therefore service life of the bearing is prolonged and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of bearing, specifically a kind of magnetic suspension bearing.
Background technique
Bearing is the mechanically operated vitals of a kind of realization, and existing bearing generally is divided into rolling bearing and sliding bearing two big classes, and it all needs to consume certain power for overcome friction in transmission, in order to reduce friction, need take various forms of lubricating, complicated operation increases maintenance cost.In addition because equipment turns round for a long time, the weakening etc. of the rising of temperature, greasy property make bearing fragile, burn out, and the friction of bearing inevitably produces mechanical vibration, brings mechanicalness noise, is unfavorable for the steady running of equipment.Reduce friction between the bearing part though prior art is adopted various measures,, can reduce the working efficiency of bearing because the relation of the releasing between the bearing part must have friction therebetween.
The model utility content
The purpose of this utility model is to provide a kind of magnetic suspension bearing, zerofriction force between each parts of this bearing, thus make the working procedure noise free, and the life-span is long, high working efficiency.
The technical scheme in the invention for solving the technical problem is: a kind of magnetic suspension bearing, comprise bearing support and axle sleeve, it is characterized in that, described bearing support is the magnetic bearing seat, the magnetic rotatable parts of described axle sleeve for rotating in the magnetic bearing seat, the part that described magnetic rotatable parts are arranged in the magnetic bearing seat is identical with the polarity of magnetic bearing seat.
Described magnetic bearing seat is an outer ring ring magnet, and described magnetic rotatable parts are an inner ring ring magnet, and outer ring ring magnet and inner ring ring magnet have homopolarity magnetic force with respect to each symmetric points in axle center.
Described bearing support and axle sleeve are made by permanent magnet.
The magnetic of described bearing support and axle sleeve is formed by high pulse voltage.
The beneficial effects of the utility model are: bearing support and axle sleeve all have magnetic, make it after combination, produce certain radially repulsive force, overcome the serious defective of each parts friction in the traditional bearing working procedure, can not produce noise in the working procedure, also need not to lubricate, and long service life, high working efficiency.
Description of drawings
Fig. 1 is a horizontal section structural representation of the present utility model;
Fig. 2 is a longitudinal profile structural representation of the present utility model;
Among the figure: 1 bearing support, 2 axle sleeves.
Embodiment
As shown in Figure 1 and Figure 2.A kind of magnetic suspension bearing, comprise bearing support 1 and axle sleeve 2, described bearing support 1 is the magnetic bearing seat, the magnetic rotatable parts of described axle sleeve 2 for can in the magnetic bearing seat, rotating, and the part that described magnetic rotatable parts are arranged in the magnetic bearing seat is identical with the polarity of magnetic bearing seat.
Described magnetic bearing seat is an outer ring ring magnet, and described magnetic rotatable parts are an inner ring ring magnet, and outer ring ring magnet and inner ring ring magnet have homopolarity magnetic force with respect to each symmetric points in axle center.As for the N utmost point is the N utmost point, as being the S utmost point for the S utmost point.Described bearing support 1 and axle sleeve 2 are made by permanent magnet or are formed its magnetic by high pulse voltage.
During use, the inner ring ring magnet is enclosed within on the drive axle of motor, can realizes that transmission shaft can not produce friction in transmission process.
Except that specification description technique feature, all the other features are those skilled in the art and know technology.
