Abstract
A kind of radial direction attraction type permanent magnetism axial magnetic suspension bearing, it is that two are covered and are not fixed on by the round ring magnet of axial charging on the bearing inner race assembly body made of nonmagnetic substance and bearing outer ring assembly body in upper and lower side end face part or all by annular radial direction magnetic conduction yoke, and made by radial direction working gas gap the round ring magnet of radial direction working gas gap both sides the radial direction magnetic conduction yoke of annular up and down pole-face formation diametrically and make both keep attracting each other state lateral structure axial magnetic suspension bearing.
Description
Technical field
The present invention relates to magnetic suspension bearing, more particularly, to permanent magnetism magnetic suspension bearing, it is included:Attraction type permanent magnetism axial magnetic
Suspension bearing and repulsion type permanent magnetic radial magnetic suspension bearing;The invention further relates to high efficient lateral direction structure permanent magnetism magnetic suspension bearing
Method to set up.
Background technology
Among daily life, especially for the personnel often in contact with permanent magnet, in order that two pieces of axial chargings
Cylindrical magnet steel is stored together, and is unlikely to Fei Tai great strength again and can just be taken away them, always gives them with lateral
Adhesive and avoid axial adhesive, and when they are needed into separated, can also be exactly using a kind of more labour-saving way:By its
In the upper and lower end face upset of a cylindrical magnet steel exchange, the two cylindrical magnet steel is flicked immediately.This phenomenon
Meet the magnetomechanics definition of " identical charges repel each other, there is a natural attraction between the sexes ", so, deposited together by axial magnetic magnet ring of different sizes
When, they are always also carried out by lateral adhesive using inside and outside stacked form.But, this conventional techniques means is referred into side
To structure magnetic suspension bearing when, will cause annular permanent magnet magnetic energy product can not by all effectively utilize and the magnetic line of force in gas
Occur the technology drawback bent among gap magnetic circuit, so that causing the practicality of lateral structure permanent magnetism magnetic suspension bearing seriously reduces,
Up to now, this technological deficiency never by those skilled in the art cognition, this magnetic energy will be solved by also not seeing
The effective technology scheme of wasting phenomenon.
The content of the invention
The present invention to be provided is a kind of can to strengthen the magnetic suspension bearing of annular permanent magnet magnetic energy effective rate of utilization, institute
Magnetic suspension bearing is stated to include:Radial direction attraction type permanent magnetism axial magnetic suspension bearing and radial direction repulsion type permanent magnetic radial magnetic suspension bearing two
Individual fundamental type.Its technical scheme is described below:
1st, a kind of radial direction attraction type permanent magnetism axial magnetic suspension bearing, it be by two in upper and lower side end face part or all by
Annular radial direction magnetic conduction yoke is covered and is separately fixed at by the round ring magnet of axial charging to be made of nonmagnetic substance
Bearing inner race assembly body and bearing outer ring assembly body on, and radial direction working gas gap both sides are made by radial direction working gas gap
Diametrically air gap is most short so that both magnetic force for the pole-face formation of the radial direction magnetic conduction yoke of annular up and down of round ring magnet
Line is maintained at the state of straight line attraction.
In the present invention, the radial direction pole-face of the annular radial direction magnetic conduction yoke of the radial direction working gas gap both sides is aligned
And axial width is consistent;Described annular radial direction magnetic conduction yoke can also be used since one side away from working gas gap to work
Make incremented by successively on axial width in acting air gap direction.
In the present invention, the round ring magnet can also be set directly at internal rotor or outer rotor magnetic suspension shaft is promised
With on the non-magnet material body of device.
In the present invention, the end area of the round ring magnet of the radial direction working gas gap both sides can with it is equal can not also
It is equal.
2nd, a kind of radial direction repulsion type permanent magnetic radial magnetic suspension bearing, it be by two on upper and lower side end face partly or entirely
Covered by annular radial direction magnetic conduction yoke and the nonmagnetic substance system of using is separately fixed at by the round ring magnet of axial charging
On the bearing inner race assembly body and bearing outer ring assembly body of work, and two round ring magnets are made by radial direction working gas gap
The radial direction pole-face formation of the annular radial direction magnetic conduction yoke of upper and lower side is diametrically with keeping between the two mutually exclusive, effectively
The magnetic that ground adds radial direction repulsion type permanent magnetic radial magnetic suspension bearing radial direction working gas gap is close.
Among the present invention, the pole-face of the annular radial direction magnetic conduction yoke diametrically, the annular radial direction magnetic conduction
Yoke can also be used to be left on the end position of working gas gap side to working gas gap side work axial direction in round ring magnet
It is incremented by successively on thickness.
Among the present invention, the round ring magnet can also be set directly at internal rotor or outer rotor magnetic suspension bearing
On the non-magnet material body of application apparatus.
In the present invention, the round ring magnet of the radial direction working gas gap both sides can also use what axial length was not waited
Fit system, but at this moment both stringcourses must be made radially to overlap.
In summary, magnetic suspension bearing of the invention, by being arranged on round ring magnet upper and lower side annular radial guiding
The enforced guiding effect of magnetic yoke, the magnetic line of force that round ring magnet axial poles are sent gives 90 degree of direction transformation, from
And camber line closure of the magnetic line of force between inside and outside two annular permanent magnets is changed into the footpath from an annular radial direction magnetic conduction yoke
Point-blank passed through to pole-face and the most short magnetic circuit of another annular radial direction magnetic conduction yoke magnetic pole strength formation is entered after working gas gap
Flux closure loop, is effectively improved the magnetic energy utilization rate of round ring magnet.
Embodiment
