Abstract
The invention discloses a multiple rings-sheathed axial magnetic suspension bearing, which comprises a spindle (1), outer side small magnetic rings (2), small magnetic rings (3), two outer large magnetic rings (4) and the like, wherein the two outer large magnetic rings (4) are sheathed outside of the two small magnetic rings (2); two large magnetic rings (4) and the two small magnetic rings (3) are respectively arranged in a mode of opposite polarity; the outer side small magnetic rings (2) and the small magnetic rings (3) are arranged outside the two large magnetic rings (4) and the two small magnetic rings (3) in a mode of relative polarity, and jointly arranged on the spindle (1); and the axial position of a small magnetic ring set can change relative to that of the large magnetic ring set.
Description
Affiliated technical field
The present invention relates to a kind of many rings axial magnetic suspension bearing of cover mutually, this bearing is relative the big magnet ring homopolarity of a plurality of axial chargings, is arranged in together; A plurality of axial charging bead polarity are arranged in together relatively.Big magnet ring group is enclosed within the outside of bead group, makes its polarity opposed alignment between cover magnet ring mutually; Arrange a relative bead of polarity again in the outermost end of bead in addition, realize the axial suspension of big magnet ring group the bead group.Belong to the magnetic levitation technology field.
Background technique
At present, the main way that axial permanent magnetic suspends is with two relative mutual extrusion of magnet ring homopolarity, with the magnetic fidle of end pushing tow another one magnet ring homopolarity magnetic fidle of end of a magnet ring, realizes axial suspension.But because magnet ring magnetic fidle of end density is lower.So when the end face mutual extrusion realized axial suspension, its efficient was lower, and can produce radially inclined to one side power.This inclined to one side power can not be eliminated forever.
Summary of the invention
Principle of the present invention is to comprise two aspects; The first, in permanent magnet, the interior outer ledge of axial charging magnet ring exists and end face polarity opposite magnetic fields, and the direction in this magnetic field is basically perpendicular to the end face of magnet ring, can produce axial compression power to the homopolar field that is in the magnet ring edge.We can utilize two end face polarity opposite like this, and the magnet ring that can set with each other, and set with each other.Bead is near big magnet ring port, when being inserted in big magnet ring 1/3rd degree of depth, all can produce stronger axial repulsion between two magnet rings.
The second, utilize axial charging bead of the big magnet ring cover of axial charging, big magnet ring is opposite with bead polarity.The high density axial magnetic flux of so big magnet ring inboard just can produce suction to the reverse axial magnetic flux in the bead outside.Bead just can obtain bigger axial suction like this, and this axial suction is exactly axial suspension power.
In above-mentioned two kinds of axial suspension power combination together, just become many rings axial magnetic suspension bearings of cover mutually.
When the bead group moved axially in big magnet ring group, axial suspension power can constantly change, and radially partially power also can change, this design can realize, when axial suspension, can accomplish not radially power partially.
Description of drawings
Fig. 1 is many rings of the present invention radial section tectonic maps of the axial magnetic suspension bearing of cover mutually.
Fig. 2 is the radial section tectonic maps of mutual cover pushing tow structure axial magnetic suspension bearing of the present invention.
Fig. 3 is the radial section tectonic maps that mutual cover of the present invention is inhaled the structure axial magnetic suspension bearing mutually.
The present invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1, main shaft (1), outside bead (2), bead (3) and the big magnet ring of overcoat (4) etc.; Two big magnet rings of overcoat (4) are enclosed within the outside of two beads (2), other and two beads (3) the polarity opposed alignment of two big magnet ring branches (4); Outside bead (2) is relative with bead (3) polarity, is arranged in its outside, and is installed in jointly on the main shaft (1); The bead group can moving in big magnet ring group.
Among Fig. 2, main shaft (1), bead (2) and the big magnet ring of overcoat (3) etc.; Bead (2) is opposite with the polarity of the big magnet ring of overcoat (3) end face, and the internal diameter of big magnet ring (3) is greater than the external diameter of bead (2).
Just can produce huge axial suspension power this moment when big or small ring axial magnetic relative movement.
Among Fig. 3, main shaft (1), bead (2) and the big magnet ring of overcoat (3) etc.; Big magnet ring (3) is enclosed within the outside of bead (2), and two cover magnet ring polarity is opposite mutually.This structure is as long as between the same diameter magnet ring, homopolarity is arranged relatively, and just energy is installed in series for more than enough group.
Also can produce huge axial suspension power this moment when big or small ring axial magnetic relative movement.
The textural association of Fig. 2 and Fig. 3 is got up, and is exactly many rings axial magnetic suspension bearings of cover mutually.
Under the constant situation of magnet ring spread pattern,, can not influence the realization of axial suspension if the mechanical structure of magnet ring itself changes.
Claims (3)
1. ring more than a kind overlaps axial magnetic suspension bearing mutually, it is characterized in that: main shaft (1), outside bead (2), bead (3) and the big magnet ring of overcoat (4) etc.; Two big magnet rings of overcoat (4) are enclosed within the outside of two beads (2), other and two beads (3) the polarity opposed alignment of two big magnet ring branches (4); Outside bead (2) is relative with bead (3) polarity, is arranged in its outside, and is installed in jointly on the main shaft (1); The bead group can change with respect to the axial position of big magnet ring group.
2. many rings according to claim 1 are the axial magnetic suspension bearing of cover mutually, it is characterized in that: simplified structure can only keep outside bead (2) and the big magnet ring of overcoat (4), two magnet ring end face polarity opposed alignment.
3. many rings according to claim 1 are the axial magnetic suspension bearing of cover mutually, and it is characterized in that: simplified structure can only keep bead (3) and the big magnet ring of overcoat (4), and two magnet ring polarity are opposite, are nested together; This structure is as long as between the same diameter magnet ring, homopolarity is arranged relatively, and just energy is installed in series together for more than enough group.
