Abstract
The utility model relates to an outer bearing ring split type permanent magnetic suspension bearing. The problem that frictional force is too large when a bearing is rotated is solved. An upper outer ring split permanent magnetic suspension bearing sleeve (1) and a lower outer ring split permanent magnetic suspension bearing sleeve (2) are fixedly connected into an integral body by a fastening material (4) to become an outer ring bearing sleeve which has magnetism and is provided with a groove-shaped outer ring, and a magnetic inner ring permanent magnetic suspension bearing sleeve (3) is coated in the outer ring bearing sleeve. Due to the fact that the magnetic poles of the outer surface of an inner ring permanent magnetic suspension bearing sleeve (1) and the inner surface of the outer ring bearing sleeve which is provided with the groove-shaped outer ring are the same, and a gap is arranged between the inner ring permanent magnetic suspension bearing sleeve (1) and the outer ring bearing sleeve which is provided with the groove-shaped outer ring, therefore, the inner ring permanent magnetic suspension bearing sleeve (3) can be suspended, and therefore, the frictional force can be reduced.

suspending shaft bearing sleeve (3) position of position, in the outer shroud bearing housing of fluted shape, the axial position of the middle axial cavity of last outer shroud split Permanent-magnet bearing cover (1) and following outer shroud split Permanent-magnet bearing cover (2) is symmetrical, and the magnetic pole of the outer shroud bearing housing internal surface of fluted shape is identical with the outer surface magnetic pole of interior ring permanent magnetic suspending shaft bearing sleeve (3).Here said outer shroud split permanent magnetic suspending shaft bearing sleeve (1), following outer shroud split permanent magnetic suspending shaft bearing sleeve (2) and the interior ring permanent magnetic suspending shaft bearing sleeve (3) gone up can be made with NdFeB material, also the samarium-cobalt permanent-magnetic material manufacturing can be used, also iron samarium nitrogen permanent-magnet material and the stronger permanent-magnet material manufacturing of other magnetic can be used.Here said fastener material (4) can be the mechanical fastening device of bolt and so on, also can be the permanent magnetism welding consumables.When making product described in the utility model, to note, last outer shroud split permanent magnetic suspending shaft bearing sleeve (1) and the fastened material of following outer shroud split permanent magnetic suspending shaft bearing sleeve (2) (4) be affixed be integral become the outer shroud of fluted shape bearing housing after, the magnetic pole of its internal surface is identical, it is near symmetrical that the magnetic line of force of each symmetric points distributes, the magnetic pole of interior ring permanent magnetic suspending shaft bearing sleeve (3) outer surface is identical, and the magnetic line of force of each symmetric points is near symmetrical.The magnetic pole of the outer shroud bearing housing internal surface of fluted shape is identical with the magnetic pole of interior ring permanent magnetic suspending shaft bearing sleeve (3) outer surface.Because the magnetic pole between the two is identical, and then make both repel each other, because repulsion and square distance are inversely proportional to, and because of material therefor be strong permanent magnet material, and then ring levitation axis bearing sleeve (3) suspends in the bearing housing of fluted shape in making, therefore ring permanent magnetic suspending shaft bearing sleeve (3) is when being rotated by external force in, also can not collide and produces frictional force with the outer shroud bearing housing of fluted shape.
Owing to adopted such scheme, goal of the invention of the present utility model is achieved.
Below in conjunction with drawings and Examples the utility model is further specified.It provides four accompanying drawings the utility model.
Fig. 1 is the plan view of the split type permanent-magnet suspension bearing schematic representation of outer collar bearing.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the plan view of the split type permanent-magnet suspension bearing most preferred embodiment of outer collar bearing schematic representation.
Fig. 4 is the plan view of Fig. 3.
Among the figure: (1) goes up outer shroud split permanent magnetic suspending shaft bearing sleeve
(2) following ring split permanent magnetic suspending shaft bearing sleeve
(3) ring permanent magnetic suspending shaft bearing sleeve (4) fastener material in
Most preferred embodiment:
As can be seen, the split type permanent-magnet suspension bearing of the described outer collar bearing of present embodiment all the other all use the split type permanent-magnet suspension bearing of above-mentioned outer collar bearing identical from Fig. 3 and Fig. 4.Difference is that the outer ring of interior ring permanent magnetic suspending shaft bearing sleeve (3) is a triangle body, and form by last outer shroud split permanent magnetic suspending shaft bearing sleeve (1) and following outer shroud split permanent magnetic suspending shaft bearing sleeve (2), and by the outer shroud bearing housing of fastener material (4) (present embodiment fastener material (4) is a bolt, also can be a welding consumables) fluted shape of affixed one-tenth.The groove of the outer shroud bearing housing of this fluted shape is recessed triangle body.This recessed triangle body is supporting with the outer ring triangle body of interior ring permanent magnetic suspending shaft bearing sleeve (3).The outer ring triangle body of interior ring permanent magnetic suspending shaft bearing sleeve (3) can suspend in the triangle body groove of fluted shape outer shroud levitation axis bearing sleeve and not collide periphery.The magnetic pole of the internal surface of the outer shroud levitation axis bearing sleeve of fluted shape is identical, and the magnetic pole of interior ring permanent magnetic suspending shaft bearing sleeve (3) outer surface also is identical, and both magnetic poles also are identical.The boss ring of interior ring permanent magnetic suspending shaft bearing sleeve (3) and the outer shroud levitation axis bearing sleeve of fluted shape become triangle body to join platform, are relevant with the size of magnetic force.The more little sharp more then magnetic force of the angle of this supporting triangle body is more little, bears external force and the power that can continue to suspend is also more little.Otherwise the angle of this supporting triangle body is big and sharp more littler, even then magnetic force is big more not have point, bears external force and the power that can continue to suspend is also big more.
