Abstract

The invention discloses a magnetic radiation ring which comprises arc-shaped magnetic steels; a plurality of arc-shaped magnetic steels (20) are arranged in a groove (13) of an outer protection annular body (10) with the cross section of a U-shaped groove, strong glue is tightly matched and arranged between every two adjacent arc-shaped magnetic steels (20) , and the arc-shaped magnetic steels, an inner ring wall (12) and an outer ring wall (11) of the groove (14) are closely matched and provided with strong glue; the plurality of arc-shaped magnetic steels are embedded in the groove (13) of the outer protection annular body to jointly form an integrated magnetic radiation ring structure; and the magnetic polarities of the plurality of arc-shaped magnetic steels in the groove of the outerprotection annular body are same, or the magnet polarities among the adjacent arc-shaped magnetic steels are arranged in a staggered way. The magnetic radiation ring has simple structure, convenient and rapid manufacturing, even magnetic force line radiation, no magnetic line obstruction, consistent magnetism and good effect, can satisfy different actual using technology requirement conditions, improve the antioxidation performance and prolong the service life.

Description

technical field [0001] The invention relates to a magnetic ring, in particular to a magnetic radiation ring whose inside and outside of the magnetic ring have different magnetic poles. Background technique [0002] With the wide application of magnetic technology, in order to achieve the purpose of energy saving, magnetic technology is applied to such as magnetic prestressed bearings, full permanent magnetic levitation horizontal motors, magnetic levitation high-speed centrifuges, etc. The permanent magnet materials required are often ring-shaped and have radiation magnetic field, and due to the production technology and principle of magnetic materials, it is not yet possible to manufacture a magnetic ring with different magnetic poles on the inner and outer sides of the ring at one time, and what can only be obtained is a product similar to the ring of the radiating magnetic field, and even the size of the product is limited. , There are restrictions on production when the ...
