Abstract
The utility model discloses a radial axial magnetic suspension bearing substituting axial thrust, which is formed by an outer ring assembly and an inner ring assembly through a radial axial gas gap, wherein the outer ring assembly with a radial-opening annular groove at the middle position is formed by fixing two permanent magnetic magnet ring assemblies (8, 9) on an inner wall of a same bearing outer ring (10); the permanent magnetic magnet ring assemblies (8, 9) are formed by tightly sleeving two magnet rings together, and has an L-shaped radial cross section; the inner ring assembly is formed by an annular permanent magnet fixed at the middle position of a bearing inner ring (11); among the permanent magnetic magnet ring assemblies, axial magnetization is adopted for the magnet ring with a larger axial length, and internal-external single-pole radiation orientation magnetization is adopted for the magnet ring with a smaller axial length; the annular permanent magnet on the inner ring assembly adopts the magnet ring (12) which is subjected to internal-external single-pole radiation orientation magnetization, and the internal magnetic flux direction is consistent with the internal magnetic flux direction of the magnet ring with a smaller axial length in the permanent magnetic magnet ring assemblies.
Description
Technical field:
The utility model relates to magnetic suspension bearing, especially relates to permanent magnetism repulsion type footpath axial magnetic suspension bearing.
Background technique:
Current a kind of possess the axial stable suspersion ability in footpath simultaneously and can realize that the monomer-type magnetic suspension bearing achievements of technology innovation of standardized production takes the lead in being proposed by China invention circle, especially since 2011, the magnetic suspension bearing technological scheme of this type is among the swift and violent increase always.
The model utility content:
The utility model is exactly that a kind of technological innovation that possesses the axial stable suspersion ability in footpath simultaneously and can realize the monomer-type magnetic suspension bearing of standardized production will be provided, and scheme is as follows:
A kind of alternative end thrust footpath axial magnetic suspension bearing: it is closely to be connected together by two magnet rings by two to constitute the permanent magnetic ring assembly that parting face radially is shown as " L " shape and be fixed on the outer coil assembly that has the radial port annular groove on the neutral position that is formed on the same bearing outer ring inwall, and this outer coil assembly is formed by the inner ring assembly that footpath axial air-gap and annular permanent magnet that is fixed on the bearing inner race intermediate portion constitute; And make and become the side direction structure that convex-concave is intersected between the described Internal and external cycle assembly; In the middle of described permanent magnetic ring assembly, the magnet ring that axial length is bigger adopts axial charging, and a less magnet ring of axial length then adopts by the radially oriented magnet ring that magnetizes of inside and outside one pole type; Described bearing outer ring adopts low magnetic conduction or non-magnet material to make, and inner ring then is not subjected to the restriction of magnetic permeable material; Isolated by air gap or non-magnet material between the relative pole-face of low coverage between described two permanent magnetic ring assemblies; Annular permanent magnet on the described inner ring assembly adopts by the radially oriented magnet ring that magnetizes of inside and outside one pole type, and makes the interior flux of the less magnet ring of the central axial length of its interior flux direction and described permanent magnetic ring assembly consistent with each other.
In the middle of the utility model, the fixedly door of the permanent magnetic ring assembly at described outer coil assembly two ends also can adopt nonmagnetic substance to make and can extend to the inner side surface of the less magnet ring of axial length.
Description of drawings:
Accompanying drawing 1 has been explained the internal structure of the utility model permanent magnetism repulsion type footpath axial magnetic suspension bearing, wherein: (8,9) permanent magnetic ring assembly, (10) bearing outer ring, (11) bearing inner race, (12) by the radially oriented magnet ring that magnetizes of inside and outside one pole type, also namely, the outer wall of this magnet ring belongs to a magnetic pole, and inwall belongs to another magnetic pole.
Embodiment:
With concrete mode of execution the utility model footpath axial magnetic suspension bearing is further described in detail below:
A kind of alternative end thrust footpath axial magnetic suspension bearing, it is to constitute the permanent magnetic ring assembly 8,9 that parting face radially is shown as " L " shape and be fixed on the outer coil assembly that has the radial port annular groove on the neutral position that is formed on same bearing outer ring 10 inwalls by closely being connected together by two magnet rings by two, and this outer coil assembly is formed by the inner ring assembly that footpath axial air-gap and annular permanent magnet that is fixed on bearing inner race 11 intermediate portions constitute; And make and become the side direction structure that convex-concave is intersected between the described Internal and external cycle assembly; In the middle of described permanent magnetic ring assembly, magnet ring that axial length is bigger adopts to magnetizing, and a less magnet ring of axial length then adopts by the radially oriented magnet ring that magnetizes of inside and outside one pole type; Described bearing outer ring 10 adopts low magnetic conduction or non-magnet material to make 11 restrictions that are not subjected to magnetic permeable material of inner ring; Isolated by air gap or non-magnet material between the relative pole-face of low coverage between described two permanent magnetic ring assemblies; Annular permanent magnet on the described inner ring assembly adopts by the radially oriented magnet ring that magnetizes 12 of inside and outside one pole type, and makes the interior flux of the less magnet ring of the central axial length of its interior flux direction and described permanent magnetic ring assembly consistent with each other.
