Abstract
The utility model provides a magnetic levitation bearing device, comprises two small ring magnets, which are connected to two ends of a shaft and positioned at center of a large ring magnet. The magnetic field directions of the large ring magnet and the small ring magnets are radial. Inner magnetic pole of the large ring magnet has the same polarity as outer magnetic poles of the small ring magnets. Since like magnetic poles repel each other, the large ring magnet will repel the two small ring magnets toward the upper and lower sides so that the small ring magnets will be suspended with the shaft, thereby realizing the objective of levitated rotation.
Description
Technical field
The utility model relates to a kind of magnetic suspension shaft bearing apparatus, particularly a kind of precision type instrument accurate magnetic suspension shaft bearing apparatus of no surface friction drag.
Background technique
At present, bearing means adopts and rolls and sliding motion structure.The bearing means of rolling and sliding motion structure must have surface friction drag when rotating.Simultaneously, need add oiling agent at any time, cause the inconvenience of using because friction generates heat and the wearing and tearing when rotating.And the bearing means of rolling and sliding motion structure can not be used for pure oxygen environment to be used.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of simple in structure, long service life, no surface friction drag are provided, need not oiling agent, simple and reliable magnetic suspension shaft bearing apparatus.
The technological scheme that the utility model magnetic suspension shaft bearing apparatus adopts is: two circlet shape magnets are connected on the rotating shaft two ends and the center of placing a bigger toroidal magnet.The magnetic direction of bigger toroidal magnet and less toroidal magnet is for radially.The inboard magnetic pole of bigger toroidal magnet is identical with less toroidal magnet outside magnetic polarity.During bearing means work, because the magnetic pole same sex is repelled mutually, bigger toroidal magnet both sides repels less toroidal magnet up and down, and two less toroidal magnets are connected in the rotating shaft, such two less toroidal magnets together with the rotating shaft meeting is suspended by bigger toroidal magnet not with bigger toroidal magnet generation Mechanical Contact, reach the purpose that suspends and rotate.
The beneficial effects of the utility model are: do not have friction, long service life, do not generate heat, need not oiling agent, can under rugged environment, use, simple in structure, be easy to make, safety, reliably.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is a three-dimensional structure diagram.
Fig. 3 is the structural drawing that adopts two middle toroidal magnets.
Little toroidal magnet on 1. among the figure, 2. big toroidal magnet, 3. time little toroidal magnet, 4. rotating shaft.
Embodiment
In Fig. 1, little toroidal magnet 3 was placed on big toroidal magnet 2 centers under upward little toroidal magnet 1 the other end of rotating shaft 4 one ends connection connected.The magnetic direction of big toroidal magnet 2 is for radially.Go up little toroidal magnet 1 and the magnetic direction of little toroidal magnet 3 is for radially down, outside magnetic pole is identical with the inboard magnetic pole of toroidal magnet 2 greatly simultaneously.
Claims (1)
1, a kind of magnetic suspension shaft bearing apparatus, comprise little toroidal magnet, big toroidal magnet, following little toroidal magnet, rotating shaft part, it is characterized in that: little toroidal magnet was placed on big toroidal magnet center under the upward little toroidal magnet the other end of rotating shaft one end connection connected, the magnetic direction of big toroidal magnet is for radially, go up little toroidal magnet and the magnetic direction of little toroidal magnet is for radially down, outside magnetic pole is identical with the inboard magnetic pole of toroidal magnet greatly simultaneously.
