It is interior.
It is even number as the preferably described magnetic thrust mechanism group number, and with perpendicular to the center that embedded component axial line is arranged
Line is symmetrical arranged, and the magnetic thrust of the magnetic thrust mechanism on both sides applies embedded component or by package assembly to centre simultaneously to centre simultaneously
Apply, that is, ensures that embedded component or package assembly will not be along embedded component direction of axis line overexercises.
It further is equipped with the first taper face in package assembly inner wall, and the first magnet is mounted in the first taper face；Inside
Inserts outer wall is equipped with the second taper face, and the second magnet is mounted in the second taper face.First taper face and the second cone
Degree face is mutually parallel.First taper face and the second taper face can be the face with taper of an entire circle, can also be
The inclined-plane of the taper of part is for installing single magnet.
The package assembly and embedded component is the material that cannot be adsorbed by magnet, preferably stainless steel or plastics material
Matter.First magnet and the second magnet is permanent magnet.
The package assembly is fixed including two shell assembly, and two shells are respectively fitted over embedded component when installation
It is fixed by screw or other modes that are fixedly connected such as bolt or rivet or welding after upper.
Beneficial effects of the present invention：The present invention is by using installing magnetic ejection knot in gap between embedded component and package assembly
Structure makes one of embedded component or package assembly turn between so that embedded component is suspended in package assembly using magnetic mutually exclusive principle at the same level
It is dynamic, reduce the friction between embedded component and package assembly.
Description of the drawings
Fig. 1 is the sectional view of the embodiment of the present invention one；
Fig. 2 is the sectional view of the embodiment of the present invention two.
Specific implementation mode
With reference to embodiment, the invention will be further described.
Embodiment one
High-accuracy magnetic-suspension main-shaft as shown in Figure 1, the main shaft include embedded component 1 and package assembly 2, and package assembly 2 is socketed in
The outside of embedded component 1, according to actual needs can be by one of embedded component 1 or package assembly 2 as rotating member, and another is solid
Determine part, fixing piece, which is fixed on, needs position, and installation needs part to be mounted on rotating member, such as flabellum is installed on rotating member, Gu
Determine part to be fixed in the rack of certain product, there is the space rotated for embedded component 1, in package assembly 2 and embedded component 1 in package assembly 2
Between gap in be equipped at least two groups magnetic thrust mechanism, and magnetic thrust mechanism is symmetrical arranged, and ensures package assembly 2 or embedded component 1
Both sides are pressurized uniform, it is ensured that embedded component 1 will not skid off package assembly 2, and the magnetic thrust mechanism includes being mounted on 2 inner wall of package assembly
First magnet 21 of annular or several first magnets 21 of annular spread are circumferentially equipped with the of annular in 1 outer wall of embedded component
Several second magnets 11 of two magnets 11 or annular spread, and the first magnet 21 is close to the magnetic pole of 11 part of the second magnet and
Two magnets 11 are identical close to the magnetic pole of the first magnet 21, between 1 second magnet 11 of embedded component and the first magnet 21 of package assembly 2
Repulsive force makes embedded component 1 be suspended in package assembly 2.Wherein the magnetic thrust mechanism group number is even number, and with perpendicular to interior
The magnetic thrust of the center line symmetrical setting of 1 axial line of inserts setting, the magnetic thrust mechanism on both sides applies embedded component 1 to centre simultaneously
Add.Ensure that embedded component 1 will not be along 1 direction of axis line overexercise of embedded component.Further first is equipped in 2 inner wall of package assembly
Taper face 22, and the first magnet 21 is mounted in the first taper face 22；It is equipped with the second taper face 12, and the in 1 outer wall of embedded component
