Abstract
The invention relates to a tandem radial magnetic suspension bearing with split lateral depressed magnet rings, which comprises conical large magnet rings (1), conical small magnet rings (2), large annular interference waves (3), small annular interference waves (4), a medium (5) and the like, wherein the medium is arranged between the two conical large magnet rings (1) to form combined lateral depressed large magnet rings; a plurality of combined depressed large magnet rings are arranged oppositely in homopolarity to form a plurality of large annular interference waves (3); the medium (5) is arranged between the two conical small magnet rings (2) to form combined lateral depressed small magnet rings; a plurality of combined lateral depressed small magnet rings are arranged oppositely in homopolarity to form a plurality of small annular interference waves (4); and the large annular interference waves (3) are sleeved outside the small annular interference waves (4) to realize mutual radial suspension between magnet ring groups.
Description
Affiliated technical field
The present invention relates to a kind of tandem radial magnetic bearing that splits the side-facing depressions magnet ring, this magnetic suspension bearing is that the big magnet ring of side-facing depressions axial charging is disassembled into two taper magnet rings, in the centre medium is installed, antipole is arranged then, is combined into a compound side-facing depressions magnet ring; A plurality of above-mentioned fractionation side-facing depressions magnet ring homopolarities are arranged relatively, made its homopolar field phase mutual interference, produce a plurality of big annular high density disturbing waves; After in the same way the side-facing depressions bead being split, recombinant is got up, and its 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; Under the situation that magnet ring prolongs, this suspending power can be to have only homopolarity repulsion, does not have antipole suction.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 that the side-facing depressions magnet ring is split into two taper magnet rings, and medium is installed in the centre, and antipole is arranged then, is combined into a compound side-facing depressions magnet ring; A plurality of above-mentioned fractionation side-facing depressions magnet ring homopolarities are arranged relatively, made its homopolar field phase mutual interference, produce a plurality of big annular high density disturbing waves; After in the same way the side-facing depressions bead being split, recombinant is got up, and its 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.
Utilize the fractionation mode that the length of side-facing depressions magnet ring is prolonged, under the situation that magnet ring prolongs, this suspending power can be to have only homopolarity repulsion, does not have antipole suction.
Description of drawings
Fig. 1 is the radial section tectonic maps of the tandem radial magnetic bearing of fractionation side-facing depressions 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 taper (1), taper bead (2), big annular disturbing wave (3), little annular disturbing wave (4), medium (5) etc.; After between two big magnet rings of taper (1) medium being installed, form compound side-facing depressions magnet ring; Arrange relatively with the big magnet ring homopolarity of a plurality of composite recess, just can produce a plurality of big annular disturbing waves (3); Medium (5) is installed between two taper beads (2), is formed compound side-facing depressions bead; Arrange relatively with a plurality of compound side-facing depressions bead homopolarities, just can produce a plurality of little annular disturbing waves (4), big annular disturbing wave (3) is enclosed within the outside of little annular disturbing wave (4), just can realize the mutual radial suspension between the magnet ring group.
