Abstract
The utility model provides a magnetic force suspension bearing. A rotating shaft is sheathed with at least a pair of magnetic bodies; each pair of the magnetic bodies are totally correspondingly arranged through adopting the same polarity, wherein, the internal parts of each pair of the magnetic bodies are totally provided with one magnetic body which is fixed with the rotating shaft or the supporting seat. However, the other magnetic body can synchronously rotate as the rotating shaft. The corresponding surfaces of the polarity of each pair of the magnetic bodies are totally alternated annular curved surfaces; since the isotropic and repellent magnetic field force can be generated between the annular curved surfaces with the same polarity, the magnetic field force can make that each pair of the magnetic bodies can not mutually contact, and each pair of the magnetic bodies can generate frictionless and relative flotation and rotation as the rotating shaft to play the supporting and turning functions of the bearing.
Description
The utility model relates to a kind of bearing, particularly a kind of magnetic levitation bearing.
At present, at employed each class bearing of mechanical industry, all be to be made of bearing inner race, outer ring and the rolling element between Internal and external cycle, their working mechanism is to utilize and supporting that inner ring that rotating shaft is overlapped admittedly and the rolling between the rolling element realize rotating shaft and rotation.
The deficiency point of this class bearing is that its component part is many, and requires to have higher processing precision and assembly precision, therefore, and the cost height.In addition, because it is to rely on the direct contact between the part to carry out rotation work, thereby its friction torque is bigger, and bigger to the influence of transmission efficiency, particularly wearing and tearing are big, and working life is shorter.In addition, because each part of this class bearing is directly contact, mostly is the good metal of heat-conducting property again and makes, so be subjected to the influence of environment bigger, especially be subjected to Temperature Influence bigger, this also is a principal element that causes bearing decline in working life.In order to reduce wear, improve rotating effect, all to implement to lubricate to each class bearing, this just need be provided with lubricating fitting, has increased machine complexity and cost.
The bearing that uses under some high temperature, high and cold and bad working environments condition that dust is bigger also needs to set up cooling or strict sealing system, thereby has further increased equipment cost and complexity, even like this, bearing also needs often to change.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and a kind of no wearing and tearing, long-life, high efficiency magnetic force suspension bearing that leans on the no rolling element of magnetic levitation is provided.
The purpose of this utility model is to be realized by following technological scheme, on rotatingshaft, be set with at least one pair of magnetic, every pair of magnetic all is the identical correspondence settings of polarity, wherein all there are a magnetic and rotatingshaft or bearing to fix in every pair of magnetic, and another piece magnetic rotates synchronously with rotatingshaft, the corresponding face of the polarity of every pair of magnetic is ring-type curved surface separately, because all can produce the magnetic force that the same sex is repelled each other between the identical ring-type curved surface of the polarity of every pair of magnetic, this magnetic force can make every pair of magnetic not contact, rotate relative to floating and can produce frictionless, with supporting and the gyroscopic action that plays bearing with rotatingshaft.
Therefore remarkable result of the present utility model is:
Simple in structure, cheap, the life-span is high.Do not have wearing and tearing, the transmission efficiency height need not cooling and lubricated.Be adapted to use than bad working environments.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof.
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2 is the another kind of layout plan of Fig. 1.
Fig. 3 is second kind of structural drawing of the present utility model.
Fig. 4 is the schematic representation of use-case 1 of the present utility model.
Describe in detail below in conjunction with 1～4 pair of structure of the present utility model of accompanying drawing:
On rotatingshaft, be set with at least one pair of magnetic, every pair of magnetic constitutes by an outer magnetic 1 and 1 interior magnetic 2, outer magnetic 1 and interior magnetic 2 corresponding suspensions are provided with, and the correspondence of every pair of magnetic is floating, and outstanding face is set is the ring-type curved surface, and ring-type curved surface 1A is the identical setting of polarity with 2A.Referring to Fig. 1～4
Structure characteristic of the present utility model also is:
On the shaft part of the load both sides of rotatingshaft, be set with 1～2 pair of magnetic, there are fixing, another and a rotatingshaft to overlap admittedly in every pair of magnetic, the ring-type curved surface 1A of every pair of magnetic 1 is the surface of revolution of evagination, and the ring-type curved surface 2A of magnetic 2 is the surface of revolution of the indent identical with ring-type curved surface 1A profile.Referring to Fig. 1～4
Structure characteristic of the present utility model also is:
The surface of revolution that is shaped as taper or spherical shape of curved surface 1A and 2A, the every pair of magnetic center are provided with and the rotatingshaft axis hole 3 of suit mutually, and outer magnetic 1 and interior magnetic 2 positions in the every pair of magnetic are interchangeable.Referring to Fig. 1 and Fig. 2
Use-case shown in Figure 4 is that cover is loaded onto an impeller on rotatingshaft, on impeller two outside shaft parts, respectively be set with a pair of conical magnetic, the magnetic 1 of the outer convex cone shaped in its outside maintains static, then rotate with the magnetic 1 corresponding conical magnetic 2 of indent that buckles that suspends with impeller, because the identical setting of polarity, so the rotation turning surface of magnetic 1 and 2 has a conical ring at interval, this annular space then is that the magnetic force by mutual repulsion is produced, so magnetic 2 is in non-contacting state of suspension.Then use as thrust-bearing this moment.
Shown in Figure 3 is that magnetic is the planar structural type of hemisphere, and this moment, outer magnetic 1 was the bulb shape, and cover thereon be the hemisphere shelly of indent, the same Fig. 4 of use condition.
The fixing of magnetic and adjacent parts can adopt the structure of adsorbing mutually by self magnetic force and metal construction, also can adopt outsourcing to connect the structure of sheath 4 fixings.Referring to Fig. 1 and Fig. 4.
Lightweight little loading condition the utility model be our experiments show that it is fully feasible, can be for situation by strengthening the magnetic volume from great and heavy load, the situation that promptly increases magnetic force solves.The cover thereon be the hemisphere shelly of indent, the same Fig. 4 of use condition.
The fixing of magnetic and adjacent parts can adopt the structure of adsorbing mutually by self magnetic force and metal construction, also can adopt outsourcing to connect the structure of sheath 4 fixings.Referring to Fig. 1 and Fig. 2.
Lightweight little loading condition the utility model be our experiments show that it is fully feasible, can be for situation by strengthening the magnetic volume from great and heavy load, the situation that promptly increases magnetic force solves.
