Abstract
The invention discloses a symmetrical conical ring axial magnetic suspension bearing. Two symmetrical conical rings are adopted to squeeze one middle conical ring to realize axial suspension of the bearing and have a magnetic suspension bearing with very small radial deflecting force; a mechanical radial bearing can be added on the external side to realize radial support.
Description
Affiliated technical field
The present invention relates to a kind of symmetric pyramid annulate shaft to magnetic suspension bearing, the tapered collar end face that this bearing utilizes two symmetries pushes two end faces up and down of a middle tapered collar, realize that standing part supports the axial magnetic of rotating part, makes rotating part not produce axial the contact with standing part.To reach the purpose that supports thrust load.Belong to the magnetic levitation technology field.
Background technique
At present, vertical rotor often uses thrust-bearing to come the weight of support rotor, and thrust-bearing is to rely on ball to support rotor fully.Ball bearing can consume a large amount of energy when rolling friction, reduce mechanical efficiency.The life-span of ball while is not long yet, can cause service life of equipment to reduce.
Summary of the invention
In order to solve the problem that mechanical thrust pivot friction power is big and working life is short, the invention provides a kind of axial magnetic suspension bearing that is used for substituting the mechanical thrust bearing.Be used for vertical greater trochanter equipment.
The technological scheme that problem adopted that the principle of the invention solves is: axial conical suspended magnet ring is fixed on the outside of rotating part by inner washer, two taper support rings are distinguished the up and down both sides of extrusion axis to suspended ring, magnet ring obtains axially support in the middle of making, and radially inclined to one side simultaneously power also is reduced to minimum.Fixing radial bearing on the axis is to realize radial support.
Description of drawings
Fig. 1 is the radial section tectonic maps of symmetric pyramid annulate shaft of the present invention to magnetic suspension bearing.
Fig. 2 is the radial section tectonic maps of right angle side annulate shaft of the present invention to magnetic suspension bearing.
The present invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1,1, two taper symmetry of rotating shaft cover extrusion ring 2, the middle cone oblique crank Z overlaps 4 to suspended ring 3 in the axial suspension ring.Wherein 2 pairs of middle cone oblique crank Zs of two taper symmetry extrusion rings push to suspended ring 3, make the middle cone oblique crank Z be in the axial suspension state to suspended ring 3.The middle cone oblique crank Z to suspended ring 3 by the axial suspension ring in cover 4 be connected with rotating shaft cover 1, make rotating shaft overlap 1 and be in the axial suspension state.On the rotating shaft cover 1 radial bearing can also be installed, to realize radial support.
Fig. 2 be right angle side annulate shaft of the present invention to magnetic suspension bearing, its agent structure and Fig. 1 are identical, just the edge of its magnet ring is the right angle.The shortcoming of this bearing is a requirement machining accuracy height.
Except that above embodiment, the present invention also has other mode of executions.All employings are equal to the technological scheme of replacement, equivalent deformation formation, all drop in protection scope of the present invention.
Claims (4)
