Abstract
The invention relates to a horizontal motion magnetic suspension device with a conical front part of a magnet. The horizontal motion magnetic suspension device is composed of a large conical axial magnetization magnet ring (1) at inner side surface, a large conical axial magnetization magnet ring (2) at inner side surface, a small conical axial magnetization magnet ring (3) at outer side surface, a small conical axial magnetization magnet ring (4) at outer side surface, a large annular interference wave (5), a small annular interference wave (6) and the like; the large conical axial magnetization magnet ring (1) at inner side surface and the large conical axial magnetization magnet ring (2) at inner side surface are arranged with opposite like poles to generate the large annular interference wave (5); the small conical axial magnetization magnet ring (3) at outer side surface and the small conical axial magnetization magnet ring (4) at outer side surface are arranged with opposite like poles to generate the small annular interference wave (6); and the large annular interference wave (5) sleeves the small annular interference wave (6).
Description
Art
The present invention relates to the horizontal motion magnetic levitation system that magnetic patch front portion is cone structure, this magnetic suspension bearing utilizes multiple inboard cone shape axial charging large magnet ring homopolarity arranged opposite, and its homopolar field is disturbed mutually, produces multiple large annular high density disturbing wave; With the outside taper axial charging bead of equivalent amount, homopolarity arranged opposite, produces multiple little annular high density disturbing wave; Large magnet ring disturbing wave is enclosed within the outside of homopolarity bead disturbing wave, just can realizes large magnet ring group and the brute force of bead group is suspended, and there is axial suspension power; When magnet ring extends, this suspending power can be only have homopolarity repulsion, does not have antipole suction.Belong to magnetic levitation technology field.
Background technique
Before for many years, more external researchers doing permanent magnetism magnetic suspension bearing once write a book, a kind of similar axial magnetic bearing structure is described inside book, but conclusion is wherein permanent-magnet material can not realize magnetic suspension bearing, the high radial power magnetic suspension with industrial application value more can not be realized.According to the image display on that this book, the large magnet ring in its design and the gap between bead should and rotor, gap between stator close, namely below a millimeter.Domestic some magnetic suspension bearings expert all thinks that permanent-magnet material can not realize the magnetic suspension of high radial power, and does not also have production out in our prior, also there are no any relevant report in the 3rd magnetic suspension bearing meeting.
Summary of the invention
Principle of the present invention is the axial charging large magnet ring homopolarity arranged opposite utilizing inner side conical surface, its homopolar field is disturbed mutually, produces multiple large annular high density disturbing wave; With same
Etc. the outer side surface taper axial charging bead of quantity, homopolarity arranged opposite, produces multiple little annular high density disturbing wave; Large magnet ring disturbing wave is enclosed within the outside of homopolarity bead disturbing wave, just can realizes the mutual suspension between magnet ring group.
Suspension between tapered slope magnet ring group, at disturbing wave not in conplane situation, can produce axis and radial suspension force simultaneously.If but magnet ring length is less than the length of back suction ripple, just there is antipole suction in the end thrust of magnet ring.Now need the length increasing magnet ring, make back suction power reduce to minimum, just while realizing radial suspension, can also realize axially symmetrical suspension.
Embodiment
Wherein, the large magnet ring of inner side surface taper axial charging, the large magnet ring of inner side surface taper axial charging, outer side surface taper axial charging bead, outer side surface taper axial charging bead, large annular interference involves little annular disturbing wave etc.; The large magnet ring of inner side surface taper axial charging and inner side surface taper axial charging large magnet ring polarity arranged opposite, produce large annular disturbing wave; Outer side surface taper axial charging bead and outer side surface taper axial charging bead homopolarity arranged opposite, produce little annular disturbing wave; Large annular disturbing wave is enclosed within outside little annular disturbing wave.
Claims (1)
1. magnetic patch front portion is the horizontal motion magnetic levitation system of cone structure, it is characterized in that: the large magnet ring of inner side surface taper axial charging, the large magnet ring of inner side surface taper axial charging, outer side surface taper axial charging bead, outer side surface taper axial charging bead, large annular interference involves little annular disturbing wave etc.; The large magnet ring of inner side surface taper axial charging and inner side surface taper axial charging large magnet ring polarity arranged opposite, produce large annular disturbing wave; Outer side surface taper axial charging bead and outer side surface taper axial charging bead homopolarity arranged opposite, produce little annular disturbing wave; Large annular disturbing wave is enclosed within outside little annular disturbing wave.
