Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] Figure 1a It is an axial view of the spliced magnetic ring with a hole structure in the middle of the magnetic block. There is a hole (2) in the middle of the spliced magnetic block (1) for fixing the magnetic block. When fixing, a screw passes through it. Together, they form a complete ring structure of permanent magnets.
[0031] Figure 1b It is a radial cross-sectional view of the spliced magnetic ring assembly with a hole structure in the middle of the magnetic block, including: axially magnetized spliced magnetic block (1), fixing hole (2), fixing screw (211), complete annular magnetizer (3 ), magnetization direction corner magnetic block (101), annular magnetizer with threaded hole (301) and fixing nut (8) and other components; the fixing hole (2) of axial magnetization splicing magnetic block (1) is set in On the fixing screw (211), the fixing...

Abstract
The invention discloses a magnetic block spliced magnetic ring type magnetic suspension bearing. The magnetic block spliced magnetic ring type magnetic suspension bearing is mainly characterized in that fixing holes of axial magnetizing splicing magnetic blocks are arranged on fixing screw rods in a sleeving mode, and the fixing screw rods are inserted into fixing holes of complete annular magnetizers to make the axial magnetizing splicing magnetic blocks be stuck to the side faces of the complete annular magnetizers, and axial magnetizing complete magnetic ring structure combinations are formed; the magnetizing directions of spliced magnetic blocks of each axial magnetizing complete magnetic ring structure combination are all the same, and the magnetizing directions of every two adjacent magnetic axial magnetizing complete magnetic ring structure combination are opposite; a complete annular magnetizer is sandwiched between the end faces of every two adjacent spliced magnetic rings; the last annular magnetizer is an annular magnetizer which is provided with threaded holes and is in threaded fastening with the fixing screw rods, and fixing nuts are further installed on the outer sides; the axial magnetizing splicing magnetic blocks further internally comprise magnetizing directional corner magnetic blocks, and the multiple magnetizing directional corner magnetic blocks are installed on the side faces of the complete annular magnetizers.
Description
Technical field [0001] The present invention relates to a magnetic block splicing magnetic ring type magnetic suspension bearing. Specifically, the magnetic block and the magnetizer are mechanically fixed together by splicing to form a composite magnetic ring structure, and multiple composite magnetic ring structures are axially They are connected in series to form a fixed composite magnetic ring structure and a rotating composite magnetic ring structure. Using the interaction of the permanent magnetic waves generated on the side, the fixed composite magnetic ring structure can attract and repel the rotating composite magnetic ring structure, and the rotating parts and the rotating composite magnetic ring structure can be realized. Magnetic support system for fixed parts. It belongs to the technical field of magnetic levitation. Background technique [0002] The idea of using magnetic force to manufacture bearings without mechanical friction has long existed. However, it ...
