Abstract
The invention discloses a radial and axial magnetic levitation bearing for replacing centripetal thrust. The radial and axial magnetic levitation bearing is formed by an outer ring assembly which is formed at the middle position formed by fixing two specially-shaped piece annular permanent magnets on the inner wall of the same bearing outer ring and is provided with a radial opening annular groove, and an inner ring assembly formed by an annular permanent magnet fixed at the middle part of a bearing inner ring through a radial and axial air gap, wherein the radial cross section of each specially-shaped piece annular permanent magnet is displayed into an L-shaped annular magnetic ring and an inner magnetic flow is axial magnetization; the close opposite magnetic pole faces of the two specially-shaped piece annular permanent magnets are separated by the air gap; the annular permanent magnet is internally provided with a magnetic ring utilizing inside and outside monopole type radiation to orientate and magnetize; and the inner magnetic flows of the permanent magnets on the bearing outer ring assembly and the permanent magnet on the bearing inner ring are vertical to each other.
Description
?
Technical field:
The present invention relates to magnetic suspension bearing, especially relate to axially magnetic suspension bearing of permanent magnetism repulsion type footpath.
Background technique:
Current a kind of possess simultaneously the axial stable suspersion ability in footpath and can realize that the monomer-type magnetic suspension bearing achievements of technology innovation of standardized production takes the lead in being proposed by China invention circle, especially since 2011, the magnetic suspension bearing technological scheme of this type is among the swift and violent increase always.
Summary of the invention:
The present invention will provide a kind of technological innovation that possesses simultaneously the axial stable suspersion ability in footpath and can realize the monomer-type magnetic suspension bearing of standardized production, and scheme is as follows:
1, the axial magnetic suspension bearing in a kind of alternative centripetal thrust force footpath, it is formed on the neutral position with the outer coil assembly of radial port annular groove and is formed by the inner ring assembly that the axial air gap in footpath and annular permanent magnet that is fixed on the bearing inner race intermediate portion consist of by be fixed on same bearing outer ring inwall by two profiled piece annular permanent magnets; Thereby make the Internal and external cycle assembly become the side direction structure that convex-concave is intersected; The radially parting face of described profiled piece annular permanent magnet is shown as the annular magnet ring of " L " shape, and its interior flux is axial charging; Described bearing outer ring all adopts low magnetic conduction or non-magnetic material of leading to make, and inner ring is then unrestricted; Between the relative magnetic pole strength of described two profiled piece annular permanent magnet low coverages by air gap or non-magnet material magnetic open circuit; Described annular permanent magnet adopts the inside and outside radially oriented magnet ring that magnetizes of monopole type; The magnetic force that the permanent magnet of axial air gap both sides, described footpath produces remains on the state of mutual repulsion; The interior flux of the permanent magnet on the permanent magnet on the described bearing outer ring assembly and the bearing inner race is mutually vertical.
In the middle of the present invention, the permanent magnet at described outer coil assembly two ends all can be covered by the magnetic conductivity bearing (ball) cover; And described bearing (ball) cover can also extend to the inner side surface of profiled piece annular permanent magnet.
In the middle of the present invention, the permanent magnet in the middle of the described outer coil assembly also can be by two length once the consistent permanent magnet of interior flux direction not be consisted of, and the interior flux of the permanent magnet on the interior flux that makes these two permanent magnets and the bearing inner race is mutually vertical.
Description of drawings:
Accompanying drawing has been explained the axially internal structure of magnetic suspension bearing of permanent magnetism repulsion type of the present invention footpath, wherein: (1,2) profiled piece annular permanent magnet, (3) the inside and outside radially oriented magnet ring that magnetizes of monopole type, also namely: the outside omnidirectional of magnet ring is same magnetic pole, inboard omnidirectional then is another magnetic pole, (4) bearing inner race, (5) bearing outer ring, (6,7) belong to the catch of bearing end.
Embodiment:
The below further describes in detail the axial magnetic suspension bearing in the present invention footpath with concrete mode of execution:
Shown in accompanying drawing, the axial magnetic suspension bearing in footpath of the present invention, by be fixed on by two profiled piece annular permanent magnets same bearing outer ring inwall be formed on the neutral position with the outer coil assembly of radial port annular groove by the footpath axially the inner ring assembly that consists of of air gap and annular permanent magnet that is fixed on the bearing inner race intermediate portion formed; Thereby make the Internal and external cycle assembly become the side direction structure that convex-concave is intersected; The annular magnet ring that described profiled piece annular permanent magnet 1,2 radially parting face are shown as " L " shape, its interior flux is axial charging; Described bearing outer ring 5 all adopts low magnetic conduction or non-magnetic material of leading to make, and 4 of inner rings are unrestricted; Between the relative magnetic pole strength of described two profiled piece annular permanent magnet low coverages by air gap or non-magnet material magnetic open circuit; Described annular permanent magnet adopts the inside and outside radially oriented magnet ring that magnetizes 3 of monopole type; The magnetic force that the permanent magnet of axial air gap both sides, described footpath produces remains on the state of mutual repulsion; The interior flux of the permanent magnet on the permanent magnet on the described bearing outer ring assembly and the bearing inner race is mutually vertical.
