Abstract
The invention relates to an incomplete annular interference wave magnetic suspension bearing which comprises an axially-magnetized incomplete large magnet ring (1), an axially-magnetized incomplete large magnet ring (2), a small magnet ring (3), a small magnet ring (4), an incomplete annular interference wave (5), a small annular interference wave (6) and the like, wherein the homopolar magnetic fields of the large magnet ring (1) and the large magnet ring (2) are opposite to each other so as to form mutual interference and produce the incomplete annular interference wave (5), and a notch is arrange at the upper part; homopolar end surfaces of the small magnet ring (3) and the small magnet ring (4) are opposite to each other, so that magnetic fields form mutual interference and produce the small annular interference wave (6); and the small annular interference wave (6) is mounted at the inner side of the incomplete annular interference wave (5), so that the small annular interference wave (6) can drive the small magnet ring (3) and the small magnet ring (4) to be in an upward radial suspension state.
Description
Affiliated technical field
The present invention relates to a kind of imperfect annular disturbing wave magnetic suspension bearing; This magnetic suspension bearing is that two imperfect magnet ring polarity of axial charging are arranged relatively; Make the mutual interference of two magnet ring homopolar field phases; Because magnet ring is that size is identical, and is incomplete loop configuration, so produce the highdensity disturbing wave of a kind of imperfect annular; Two beads identical with the outer shroud magnetizing direction of side installation are within it arranged its polarity relatively again, and the mutual interference of two bead homopolar field phases contacts the end face outside this moment and can produce an annular disturbing wave of the high density with imperfect disturbing wave homopolarity; Utilize above-mentioned two highdensity annular disturbing wave mutual extrusion, just can realize the radial suspension of imperfect big magnet ring group the bead group; Certainly if inboard fixing, during outer sideway swivel, just should make bead be in imperfect state, big magnet ring is kept perfectly; If in the time of simultaneously on the vertical plane with main shaft of these two high density magnetic field, will produce axially inclined to one side power at one; Utilize two symmetry axis to inclined to one side power, just can realize axial suspension.Belong to the magnetic levitation technology field.
Background technique
The front, we have obtained a kind of high density disturbing wave through test, and this disturbing wave is applicable to symmetrical extruded magnetic suspension bearing.But under symmetrical squeezed state; When being in the main bearing carrying capacity of state of suspension still off-centre can appear; The needs that can not adapt to horizontal equipment are so we become imperfect magnet ring disturbing wave structure with complete magnet ring disturbing wave architecture advances, through debugging; Can make horizontal equipment under the situation of load weight, be in home position when realizing radial suspension.
Summary of the invention
Principle of the present invention is to utilize two big magnet ring polarity of imperfect annular to arrange relatively, makes the mutual interference of two magnet ring homopolar field phases, and this moment, two magnet ring inboards will produce the high density disturbing wave of an imperfect annular; Be installed in two minor diameter magnet rings jointly on the main shaft again, make its homopolar field phase mutual interference, contact this moment the end face outside can produce one with the bead high density disturbing wave of magnet ring disturbing wave homopolarity greatly; With above-mentioned two high density annular disturbing wave mutual extrusion perpendicular to axial direction, just can realize the radial suspension of imperfect magnet ring ring group to the bead group; When above-mentioned two high density annular disturbing wave not same perpendicular to the plane of main shaft on the time, will produce axially power partially between the magnet ring group.The axially inclined to one side power of two symmetrical balances is installed on the same main shaft, just can realize axial magnetic suspension.

Below in conjunction with accompanying drawing the present invention is further specified.
Among Fig. 1, the imperfect big magnet ring of axial charging (1), the imperfect big magnet ring of axial charging (2), bead (3), bead (4), imperfect annular disturbing wave (5) and little annular disturbing wave compositions such as (6); Big magnet ring (1) is relative with big magnet ring (2) homopolar field, and the phase mutual interference produces imperfect annular disturbing wave (5), and breach is on top; Bead (3) is relative with bead (4) homopolarity end face, and magnetic field phase mutual interference produces little annular disturbing wave (6); Little annular disturbing wave (6) is installed in the inboard of imperfect annular disturbing wave (5), and little annular disturbing wave (6) just can drive bead (3) and be in upwards radial suspension state with bead (4).
Fig. 2 is the axial view of Fig. 1.
Among Fig. 3, the imperfect big magnet ring of axial charging (1), the complete big magnet ring of axial charging (2) are arranged in the mutual polarity of the imperfect big magnet ring of axial charging (3) relatively, make its homopolar field phase mutual interference, produce a plurality of imperfect annular disturbing waves (7); Bead (4), bead (5) are arranged in the mutual polarity of bead (6) relatively, make its homopolar field phase mutual interference, produce a plurality of complete annular disturbing waves (8); Disturbing wave (8) is installed in the disturbing wave (7), and homopolarity is corresponding.
It among Fig. 4 the axial view of Fig. 3.
Said structure is horizontal inner suspension rotational structure.If the big magnet ring in the outside is complete magnet ring, inboard bead is imperfect magnet ring, just can adapt to the requirement of inner rotary equipment.
In said structure, we can also install magnetic patch in the indentation, there of an imperfect magnet ring, and this magnetic patch is opposite with the magnetizing direction of corresponding imperfect magnet ring, forms a compound magnet ring that two kinds of magnetizing directions are arranged.Arrange relatively with a plurality of this compound magnet ring polarity again, produce the annular disturbing wave that two kinds of polarity are arranged, be used for said structure.Complete annular disturbing wave like this will receive the extruding of following homopolarity disturbing wave, also receives the attraction of top antipole disturbing wave simultaneously, improves radial suspension load.
We can also install other magnet cases in the indentation, there of imperfect magnet ring in addition, and magnet case can produce middle suspension magnet ring group equally and attract like this, improves upwards radial suspension load.
The mechanical structure of magnetic patch changes, and for example magnetic patch presents taper, trapezoidal, inside and outside groove and irregular taper, and generation that all can shadow magnetic patch the two poles of the earth end face permanent magnetism ripple can not influence the generation of N utmost point disturbing wave and S utmost point disturbing wave simultaneously yet.
