Specific implementation mode
Embodiment 1
As shown in Figs. 1-3, as shown in Figure 1, hollow revolving platform structural schematic diagram.The generally hollow cylinder class of rack 1 is returned
Swivel, is evenly arranged with the connecting hole 111 of connection at outer circle terminal pad.Solid lock ring 2 is installed in the top of rack 1, Gu
Lock ring 2 is a rounded ring body, is screw-locked at the periphery on 1 top of rack.Be equipped between solid lock ring 2 and push pipe part 5 packaging ring 3 and
Sealing ring 4.Push pipe part 5 and bottom tube part 6 are cylinder type hollow revolving body.Push pipe part 5, which is fixed with bottom tube part 6 by bolt 8, to be connected
It connects.Rack 1, solid lock ring 2, push pipe part 5 and bottom tube part 6 are both provided with toroidal cavity, are combined into a circular ring shape and embed space, use
To install magnetic bearing 7.Uniformly distributed groove is machined in the central shaft hole of bottom tube part 6 to be used for that strip magnet steel 9 is installed.Cup type is isolated
It is stretched into hole by bolted on connection, cup type part between cover 14 and bottom tube part 6.Sealing is provided between isolation cover 14 and bottom tube part
Circle.The input shaft 11 for being equipped with adjusting sleeve 12 is arranged in isolation cover, is adjusted and is equipped with annular magnetic steel 13 outside sleeve, and with
The bar magnet magnetic coupling installed in centre bore.Input shaft can drive bottom tube part 6 and push pipe part 5 to form stage body when rotating turns
It is dynamic.
Such as Fig. 2, shown in 3, magnetic bearing structural schematic diagram.It is all machined on outer ring 2, upper end cover 22 and bottom end cover 23 uniformly distributed
Groove be used for several triangle magnet steel are installed.Adjusting bracket 26 is installed in inner shaft.The mid diameter of adjusting bracket is more than two
Diameter is held, several magnet steel opposite with outer ring magnetic steel are installed.It is required that adjustment magnet steel position makes inner ring steel magnet Impact direction converge
In same point.Magnet steel (upper inner ring shape magnet steel and upper outer shroud magnet steel, lower inner ring shape magnet steel and lower outer shroud magnet steel) between inner ring, outer ring
Inclined-plane is generated the repulsion perpendicular to inclined-plane by mutually exclusive, and component axially and radially makes rotor suspension in the stator
Between, ensure that rotor steadily can reach balance when rotating speed is sufficiently large in six-freedom degree, and bear radial direction in a certain range
Power and axial force.
