Abstract
The invention relates to a linear conical magnetic suspension bearing which comprises an inner-surface conical axial magnetized big magnetic loop (1), an inner-surface conical axial magnetized big magnetic loop (2), an outer-surface conical axial magnetized small magnetic loop (3), an outer-surface conical axial magnetized small magnetic loop (4), a big annular interference wave (5), a small annular interference wave (6) and the like, wherein unlike poles of the inner-surface conical axial magnetized big magnetic loop (1) and the inner-surface conical axial magnetized big magnetic loop (2) are arranged opposite to each other to produce the big annular interference wave (5); like poles of the outer-surface conical axial magnetized small magnetic loop (3) and the outer-surface conical axial magnetized small magnetic loop (4) are arranged opposite to each other to produce the small annular interference wave (6); and the big annular interference wave (5) is sheathed outside the small annular interference wave (6). When the big annular interference wave (5) and the small annular interference wave (6) are not positioned on the same plane, axial and radial suspension forces can be generated simultaneously.
Description
Affiliated technical field
The present invention relates to a kind of straight line taper magnetic bearing, this magnetic suspension bearing is to utilize a plurality of inboard cone oblique crank Zs to arrange relatively to the big magnet ring homopolarity that magnetizes, and makes its homopolar field phase mutual interference, produces a plurality of big annular high density disturbing waves; With the outside taper axial charging bead 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 of the brute force suspension of big magnet ring group, and have axial suspension power 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 to utilize the big magnet ring homopolarity of axial charging of inboard conical surface to arrange relatively, makes its homopolar field phase mutual interference, produces a plurality of big annular high density disturbing waves; With the outer side surface taper axial charging bead 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 suspension between the magnet ring group.
Suspension between the tapered slope magnet ring group, can produce axially and radial suspension force not under conplane situation simultaneously at disturbing wave.If but just there is antipole suction in magnet ring length less than the length of back suction ripple in the end thrust of magnet ring.Need to increase the length of magnet ring this moment, makes back suction power reduce to minimum, just can realize that also axially symmetry suspends when realizing radial suspension.
Description of drawings
Fig. 1 is the radial section tectonic maps of straight line taper magnetic bearing 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 inner side surface taper axial charging (1), the big magnet ring of inner side surface taper axial charging (2), outer side surface taper axial charging bead (3), outer side surface taper axial charging bead (4), big annular disturbing wave (5) and little annular disturbing wave (6) etc.; Big magnet ring of inner side surface taper axial charging (1) and relative arrangement of the big magnet ring of inner side surface taper axial charging (2) polarity produce big annular disturbing wave (5); Outer side surface taper axial charging bead (3) and relative arrangement of outer side surface taper axial charging bead (4) homopolarity produce little annular disturbing wave (6); Big annular disturbing wave (5) is enclosed within little annular disturbing wave (6) outside.
When big annular disturbing wave (5) and little annular disturbing wave (6) not at grade the time, can produce simultaneously axially and radial suspension force.
