Abstract
The utility model relates to a magnetic suspension bearing, which comprises a magnetic bearing block and a magnetic rotating component which can rotate in the magnetic bearing block, and the portion of the magnetic rotating component which is arranged in the magnetic bearing block has the same polarity as the magnetic bearing block. The magnetic suspension bearing provides a magnetic suspension bearing which has no frictional force between bearing components, can not generate mechanical vibration, is beneficial to stable operation of the device, and increases working efficiency of bearing.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of magnetic suspension bearing.
Background technique
Bearing is the mechanically operated vitals of a kind of realization, when realizing mechanical connection, mainly plays a part to reduce the mechanical friction between the connected element surface of contact.Be widely used in the bearing in the industry at present, employing be that the axis of rolling connects, be to roll contact between rolling surface and the rolling element, by the lubricated base filled out in the bearing configuration and by supplemental lubrication agent (lubricating grease) with the friction between minimizing rolling surface and the rolling element.Because mechanism, aging and pollute increase, the lubricated base of being filled out in the bearing configuration will lose its greasy property gradually, the additional blanking time of oiling agent (lubricating grease) can be shorter and shorter, especially in the big machinery interlock that runs up, in order to ensure the normal operation of machinery, often need to be equipped with special equipment, as oil pump, give bearing supplemental lubrication agent incessantly (lubricating grease), complicated operation has increased maintenance cost, in addition, also can owing to weakening of the rising of the long-time running of equipment, temperature, greasy property etc. make bearing fragile, burn out.And, this axis of rolling connection produces mechanical vibration inevitably, bring mechanicalness noise, be unfavorable for the steady running of equipment, though the more important thing is prior art simultaneously adopts various measures to reducing the friction between the bearing part, but, can reduce the working efficiency of bearing because the contact relation between the bearing part must have friction therebetween.
The model utility content
The utility model is the above-mentioned technical problem of the bearing existence in the solution background technique, and the magnetic suspension bearing of zerofriction force between a kind of bearing part is provided.
Technical solution of the present utility model is: the utility model is a kind of magnetic suspension bearing, its special way is: described bearing comprises magnetic bearing seat and the magnetic rotatable parts that can rotate in the magnetic bearing seat, and the part that the magnetic rotatable parts are arranged in the magnetic bearing seat is identical with the polarity of magnetic bearing seat.
Above-mentioned magnetic rotatable parts are the magnetic axle, and the end that the magnetic axle is arranged in the magnetic bearing seat is identical with the polarity of magnetic bearing seat.
The other end of above-mentioned magnetic axle is provided with flange.
Above-mentioned magnetic rotatable parts are the annular magnet inner ring, and it is interior and identical with the polarity of magnetic bearing seat that the annular magnet inner ring is arranged on the magnetic bearing seat.
Above-mentioned magnetic bearing seat is provided with the ring baffle that prevents that the annular magnet inner ring from swinging.
Above-mentioned magnetic bearing seat is the annular magnet bearing support.
Above-mentioned magnetic bearing seat and magnetic rotatable parts are made by permanent magnet.
The magnetic of above-mentioned magnetic bearing seat and magnetic rotatable parts is formed by high pulse voltage.
Employing magnetic bearing seat of the present utility model and the magnetic rotatable parts that can rotate in the magnetic bearing seat constitute magnetic suspension bearing, magnetic rotatable parts in this bearing are because identical with the polarity of magnetic bearing seat, therefore the magnetic rotatable parts can be suspended in the magnetic bearing seat, in rotation process, can not come in contact with the magnetic bearing seat, therefore there is not mechanical friction, do not have the machinery wearing and tearing, need not to be provided with lubricated base yet, add oiling agent.Because the magnetic connection is a kind of flexibly connecting,, be beneficial to the stable operation of equipment simultaneously so the utility model can produce mechanical shock hardly in application process.
The utility model has the advantages that: simple in structure, there is not cloudy power, energy-conservation, safe and reliable, high resilience.
