Abstract
The invention discloses a magnetic suspension bearing with series-wound side-protruded magnetic rings, which comprises side-protruded axial magnetized large magnetic rings (1), side-protruded axial magnetized small magnetic rings (2), large annular interference waves (3), small annular interference waves (4) and the like. The plurality of side-protruded axial magnetized large magnetic rings (1) have opposite polarities, and generate a plurality of large annular interference waves (3); the plurality of side-protruded axial magnetized small magnetic rings (2) are arranged in a way that the polarities are opposite, and generate the small annular interference waves (4); and the large annular interference waves (3) are sleeved outside the small annular interference waves (4) in a way that the same polarities are arranged in the same plane.
Description
Affiliated technical field
The present invention relates to a kind of magnetic suspension bearing of tandem raised side magnet ring, this magnetic suspension bearing is to utilize a plurality of inboard big magnet ring homopolarities of axial charging that protrude to arrange relatively, makes its homopolar field phase mutual interference, produces a plurality of big annular high density disturbing waves; The axial charging bead is protruded in the outside with equivalent amount, and homopolarity is arranged relatively, produces a plurality of little annular high density disturbing waves; Big magnet ring disturbing wave is enclosed within the outside of homopolarity bead disturbing wave, just can realizes the powerful radial suspension of big magnet ring group the bead group.Belong to the magnetic levitation technology field.
Background technique
Before for many years, more external researchers that do the permanent magnetism magnetic suspension bearing once write a book, a kind of similar axial magnetic bearing structure has been introduced in the book the inside, but conclusion wherein is a permanent-magnet material can not realize magnetic suspension bearing, more can not realize having the high radial power magnetic suspension of industrial application value.Show according to the image on that this book, big magnet ring in its design and the gap between the bead should and rotor, stator between the gap approaching, just at one below the millimeter.Some domestic magnetic suspension bearing experts think that all permanent-magnet material can not realize the magnetic suspension of high radial power, and also do not have production to come out before us, do not see that also any relevant report is arranged in the 3rd the magnetic suspension bearing meeting.
Summary of the invention
Principle of the present invention is to utilize the inboard big magnet ring homopolarity of axial charging that protrudes to arrange relatively, makes its homopolar field phase mutual interference, produces a plurality of big annular high density disturbing waves; Protrude oblique crank Z to the bead that magnetizes with the outside of equivalent amount, homopolarity is arranged relatively, produces a plurality of little annular high density disturbing waves; Big magnet ring disturbing wave is enclosed within the outside of homopolarity bead disturbing wave, just can realizes the mutual radial suspension between the magnet ring group.
Description of drawings
Fig. 1 is the radial section tectonic maps of the magnetic suspension bearing of tandem raised side magnet ring of the present invention.
The present invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1, the big magnet ring of axial charging (1) is protruded in the side, and axial charging bead (2), big annular disturbing wave (3), little annular disturbing wave (4) etc. are protruded in the side; It is relative that the big magnet ring of axial charging (1) polarity is protruded in a plurality of sides, produces a plurality of big annular disturbing waves (3); A plurality of sides protrusion axial charging bead (2) polarity is arranged relatively, produces little annular disturbing wave (4); Big annular disturbing wave (3) is enclosed within the outside of little annular disturbing wave (4), its homopolarity is arranged at grade.
Claims (1)
1. the magnetic suspension bearing of a tandem raised side magnet ring is characterized in that: the side protrusion big magnet ring of axial charging (1), side protrusion axial charging bead (2), big annular disturbing wave (3), little annular disturbing wave (4) etc.; It is relative that the big magnet ring of axial charging (1) polarity is protruded in a plurality of sides, produces a plurality of big annular disturbing waves (3); A plurality of sides protrusion axial charging bead (2) polarity is arranged relatively, produces little annular disturbing wave (4); Big annular disturbing wave (3) is enclosed within the outside of little annular disturbing wave (4), its homopolarity is arranged at grade.
