Description
Technical field
The present invention relates to technical field of motor manufacture, specially a kind of suspension permanent magnetic bearing arrangement.
Background technique
Magnetic suspension bearing be it is a kind of using magnetic field force by rotor suspension in space, do not need any medium and realize carrying
Non-contact supporting arrangement, existing magnetic suspension bearing include inside and outside magnet ring, and outer magnetic ring is connected with fixing piece, internal magnetic ring and motor
Shaft is connected, and internal magnetic ring is located in outer magnetic ring and the two is mutually exclusive, and mutually matched work anchor ring is cylinder on two magnet rings
Face, therefore the internal magnetic ring being connected with shaft is only acted on by radial repulsion, is thus difficult to constrain the axial position of shaft, electricity
When machine shaft works, shaft is easy axial float, influences the stability of motor operation.
Summary of the invention
The object of the present invention is to provide the suspension permanent magnetic bearings for capableing of stable operation after a kind of installation.
To achieve the goals above, the technical solution of use: a kind of suspension permanent magnetic bearing, the including same core arrangement
One, two magnet ring, the interconnecting piece on the first and second magnet ring respectively for determine part, moving part is connected, side where the first magnet ring upper inner ring face and the
The magnetic pole of side is identical where outer ring surface on two magnet rings, and inside and outside anchor ring is circular conical surface, inner ring surface neighbouring and opposite cloth with outer ring surface
It sets.
Compared with prior art, technical effect of the invention are as follows: the outer ring surface of the inner ring surface of the first magnet ring and the second magnet ring
It is circular conical surface, the repulsive force that the second magnet ring is subject to is decomposed into axial force and radial force, diameter perpendicular to its outer ring surface, the repulsive force
The second magnet ring is set to suspend to power, and axial force can constrain the axial position for the moving part being connected with the second magnet ring, reduce and second
The axial movement value of the connected moving part of magnet ring, improves the stability of moving part operating.

Specific embodiment
A kind of suspension permanent magnetic bearing, the first and second magnet ring 11,12 including same core arrangement, on the first and second magnet ring 11,12
Interconnecting piece respectively for determine part, moving part is connected, outer ring surface on 11 upper inner ring face of the first magnet ring, 111 place side and the second magnet ring 12
The magnetic pole at 121 places side is identical, and inside and outside anchor ring 111,121 is circular conical surface, and inner ring surface 111 is neighbouring and opposite with outer ring surface 121
Arrangement.
As shown in fig.1, the outer ring surface 121 of the inner ring surface 111 of the first magnet ring 11 and the second magnet ring 12 is circular conical surface, the
For the repulsive force that two magnet rings 12 are subject to perpendicular to its outer ring surface 121, which is decomposed into axial force and radial force, and radial force makes
Two magnet rings 12 suspend, and axial force can constrain the axial position for the moving part being connected with the second magnet ring 12, reduce and the second magnet ring
The axial movement value of 12 connected moving parts, improves the stability of moving part operating.
Repulsion of second magnet ring, 12 part by the first magnet ring 11 in order to prevent, stability when the second magnet ring 12 being caused to operate
Difference, the inside and outside anchor ring 111,121 is parallel to each other and the two is overlapped perpendicular to the projection on its anchor ring, inside and outside anchor ring 111,
121 is fully mated, it is ensured that stability when the 12 suspension work of the second magnet ring.
The repulsive force that second magnet ring 12 is subject to can be decomposed into axial force and radial force, the inside and outside anchor ring 111 of the application,
121 bus and the angled β of its axis institute are 20 °~70 °.
The bus of inside and outside anchor ring 111,121 and the angled β of its axis institute are 45 °, the repulsive force that the second magnet ring 12 is subject to point
Solution at axial force it is identical with radial force size, it is ensured that while 31 stable suspersion of shaft, there is enough axial force constraint shafts
31 axial position reduces its axial shifting amount when shaft 31 works.
As shown in Fig. 3,4 and 5, first and second magnet ring 11,12 is that magnetic links 15 are spliced.
Part is determined and moving part is respectively electric motor end cap 32, machine shaft 31, the connection of the first magnet ring 11 as shown in Fig. 2, described
Portion is connected with electric motor end cap 32, and the interconnecting piece of the second magnet ring 12 is connected with machine shaft 51.There is arranged for interval on machine shaft 31
First and second bearing 10,20, the first and second bearing 10,20 can be the suspension permanent magnetic bearing of the application, can also be by first
Bearing 10 or second bearing 20 are set as traditional bearing, such as ball bearing or roller bearing, can further increase in this way
Stability when motor operates.
It is below the specific mounting means of the first and second magnet ring 11,12, the interconnecting piece of the first magnet ring 11 is the first ring set 13,
The annular groove for the first magnet ring 10 arrangement is offered on the inner wall of first ring set 13, the outer wall of the first ring set 13 radially stretches convex
