Abstract
The utility model relates to a machine part field. The utility model provides a magnetic suspension bearing. The permanent magnet type permanent magnet motor consists of annular permanent magnets, a shaft and disks and is characterized in that a large annular permanent magnet 1 and a small annular permanent magnet 2 are coaxial with the shaft 3, the large annular permanent magnet 1 and the small annular permanent magnet 2 are axially magnetized, the directions of magnetic poles are the same, the non-magnetic disk in one annular permanent magnet is fixed with the shaft 3, and the non-magnetic disk in the other annular permanent magnet is in movable fit with the shaft 3. The part not only can save a large amount of steel, but also increases the stability and reliability of the system and reduces vibration and noise.
Description
The utility model relates to the mechanical parts field, mainly ends as thrust that pulling shaft holds or spring.
At present, the magnetic-suspension axial bearing has two kinds, a kind of is the attraction type, another kind of is the repulsion type, the attraction type adopts magnet, and there is a natural attraction between the sexes, the repulsion type adopts the magnet same sex to repel each other, thereby offsets part or all gravity, fluid power or other mechanical force etc., contacts the frictional resistance that is produced to reduce or to eliminate because of solid.But these two kinds of magnetic suspension systems can only unidirectionally work.
The purpose of this utility model provides a kind of magnetic suspension bearing, and it has the function that attracts and repel.
The purpose of this utility model is achieved in that as shown in drawings big annular permanent magnnet 1 and circlet shape permanent magnet 2 are coaxial in axle 3, and between the big or small annular permanent magnnet axial spacing are arranged, and axle 3 is by magnetic conduction disk 4 is unfixing.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, suspension bearing is made up of annular permanent magnnet, axle and disk, it is characterized in that big annular permanent magnnet 1 and circlet shape permanent magnet 2 are coaxial in axle 3, big annular permanent magnnet 1 and little annular permanent magnnet 2 equal axial chargings, and pole orientation is identical, wherein the not magnetic conduction disk in the annular permanent magnnet is fixing with axle 3, and magnetic conduction disk and axle 3 be not movingly in another annular permanent magnnet.Otherwise, also can be fixed in circlet shape permanent magnet 2 not on the magnetic conduction fixture 4, big annular permanent magnnet 1 is by magnetic conduction disk 5 not and axle 3 movingly.When axial spacing reduced, repulsion was occupied an leading position, and then two rings repel each other; When axial spacing increased, suction was occupied an leading position, and then two rings are inhaled mutually.If circlet shape permanent magnet 2 rotates under moment loading, then end pulling shaft and hold as thrust, offset axial force.When circlet shape permanent magnet 2 does not rotate and when doing axial motion, then as magnetic spring, produces axial restoring force, or offset the power that axially changes.The mounting type of size annular permanent magnnet can exchange mutually, big fixing then little rotation or axial motion, little fixing then big rotation or axial motion.
Advantage of the present utility model: replace mechanical bearing with magnetic bearing, or replace with magnetic spring The machinery spring not only can save great deal of steel, and this magnetic suspension bearing is through repetition test, it Can also increase Systems balanth and reliability, reduce vibrating noise. It had both had the attraction function, Have again the repulsion function, can reach two-way magnetic suspension. It had both had the function of thrust bearing, again Have and end the function that pulling shaft holds; When as spring, no matter be compression or elongation, all have bullet Property power.
