Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, specifically relating to a magnetic levitation bearing that can be precisely connected. Background Technology

[0002] Magnetic bearings are a new type of high-performance bearing. Compared with traditional ball bearings, sliding bearings, and oil film bearings, magnetic bearings have no mechanical contact, allowing the rotor to reach very high operating speeds. They offer advantages such as low mechanical wear, low energy consumption, low noise, long lifespan, no lubrication required, and no oil pollution, making them particularly suitable for high-speed, vacuum, and ultra-clean environments. They can be widely used in machining, turbomachinery, aerospace, vacuum technology, rotor dynamics identification and testing, and are widely recognized as a highly promising new type of bearing.

[0003] A search revealed that application number "CN202322710329.4" discloses "a compound magnetic levitation bearing," which states that "this utility model discloses a compound magnetic levitation bearing in the field of bearings, including a first magnetic levitation bearing outer ring and an inner ring of the first magnetic levitation bearing magnetically levitated on its inner side. A screw is rotatably mounted on the center of the top of one side surface of the first magnetic levitation bearing outer ring. A second magnetic levitation bearing outer ring is provided on the side of the first magnetic levitation bearing outer ring near the screw. A second magnetic levitation bearing inner ring is magnetically levitated on the inner side of the second magnetic levitation bearing outer ring. The screw passes through the two sides of the corresponding position on the second magnetic levitation bearing outer ring. During use, the distance between the first and second magnetic levitation bearing outer rings can be easily adjusted, allowing them to adapt to different installation positions, thus improving the applicability of this compound magnetic levitation bearing and facilitating its use. However, the above-mentioned prior art still has the following problems in actual use:"

[0004] 1) In actual use, the traditional magnetic levitation bearing does not adopt the gas intervention scheme, which leads to high friction and large energy loss during the rotation of the bearing in the subsequent treatment process.

[0005] 2) Based on this, the subsequent magnetic levitation structure is treated as a traditional state, and the bearing rotation state of the subsequent magnetic levitation reduces the efficiency of friction. Utility Model Content

[0032] Example

[0033] Please see Figure 1 - Figure 7 A magnetically levitated bearing capable of precise connection includes a magnetically levitated rotating mechanism 1. The magnetically levitated rotating mechanism 1 includes an outer magnetic ring 11. A magnetic base 12 is provided on the inner wall of the outer magnetic ring 11. A plurality of magnetically levitated copper wires 13 are sequentially arranged around the top surface of the magnetic base 12. The surfaces of the magnetically levitated copper wires 13 are wrapped around the surface of the cylinder rod. A plurality of U-shaped magnetic sheets 14 for bonding are sequentially provided at the ends of the magnetically levitated copper wires 13. The surfaces of the U-shaped magnetic sheets 14 are evenly and equidistantly arranged on the inner wall of the designated outer magnetic ring 11. A plurality of adjustment openings 15 are sequentially arranged on the surface of the outer magnetic ring 11. A drive roller 16 for driving is provided in the middle of the plurality of adjustment openings 15. A sleeve base for fitting is provided at one end of the drive roller 16.

[0034] In this embodiment: the end of the outer magnetic ring 11 is provided with a turntable 17, and the middle of the turntable 17 is provided with a transmission slot 18 for transmission. One end of the transmission slot 18 is transversely interposed with the corresponding drive roller shaft 16.

[0035] The transmission slot 18 and the specific drive roller 16 are used, and one end realizes the corresponding specific interlocking drive.

[0036] In this embodiment: the surface of the outer magnetic ring 11 is provided with a drive cover 191, and a sealing cover 192 is installed at both ends of the drive cover 191. One end of the sealing cover 192 is grooved and sealed with the end face of the turntable 17.

[0037] The use of the sealing cover 192 and the corresponding turntable 17 enables the transmission of rotation in each structure, reducing friction and load on the magnetic levitation bearing.

[0038] In this embodiment: the surface of the drive cover 191 is also provided with an air supply mechanism 2;

[0039] The gas supply mechanism 2 includes pipe connectors 21 arranged on both sides of the drive cover 191. The ends of the pipe connectors 21 are sealed and connected to a U-shaped conduit 22 for pipe passage. The top end of the U-shaped conduit 22 is provided with a connecting gas valve 23.

[0040] The pipe connection structure of the zigzag conduit 22 achieves better connection and, in combination with the external connecting gas valve 23, better achieves specific gas pipe access.

[0041] In this embodiment: a nitrogen pipe connection valve 24 is provided at the top of the connecting gas valve 23. One end of the nitrogen pipe connection valve 24 is sealed and connected to an external gas pipe. A nitrogen detection box 25 is provided at the top center of the drive cover 191. An upper cover 26 for assembly is attached to the top center of the nitrogen detection box 25.

[0042] The nitrogen detection chamber 25 is used to achieve the corresponding top surface of the upper cover 26, thus achieving adaptation and sealing.

[0043] In this embodiment: a trapezoidal support base 261 is provided at the bottom center of the drive cover 191. Two trapezoidal support bases 261 are respectively symmetrically placed on the bottom two sides of the drive cover 191. The rear end of the drive cover 191 is also provided with a second magnetic ring assembly 111 that supports the outer magnetic ring 11 in front.

[0044] The outer magnetic ring 11 and the second magnetic ring assembly 111 better realize the corresponding structural push.

[0045] In this embodiment: the rear end of the second magnetic coil assembly 111 is also provided with a tail nitrogen gas mechanism 3;

[0046] The rear nitrogen mechanism 3 includes a cover 31 that is supported on the surface of the second magnetic ring assembly 111, and the side wall surface of the cover 31 has a cavity 32.

[0047] The cover structure of the cover 31 is adapted to the groove of the cavity 32.

[0049] The upper base 34 and the corresponding sealing connecting pipe 35 are used to achieve matching.

[0050] In practical use, the first step is to inject liquid nitrogen gas to enhance the initiation effect of superconductivity;

[0051] At this point, the user needs to connect one end of the corresponding pipe connector 21, and finally connect the pipe to the surface of the zig-shaped conduit 22. After loosening the connecting valve 23, connect the pipe to one end of the corresponding connecting valve 23. Through the cover state of the drive cover 191, to prevent air leakage, directly fasten one end of the turntable 17 to the surface of the sealing cover 192 to seal it. At this point, after sealing one end of the end cavity 32 to one end of the rear sealing end 33, assemble it to the back of the drive cover 191. Then, at the joint gap, pneumatically seal it according to the sealing cover 192 to prevent liquid nitrogen gas from leaking out.

[0052] Step Two: Equipment Operation;

[0053] At this time, an electric current is formed between the second magnetic ring assembly 111 and the outer magnetic ring 11. The low-temperature superconducting characteristics ensure that the outer magnetic ring 11 achieves magnetic levitation inside the drive cover 191, and it is in a superconducting state. The levitation force is achieved through the conductivity between the corresponding magnetic base 12 and the embedded magnetic levitation copper wire 13. The rotating roller structure rotates around the surface of the U-shaped magnetic sheet 14, realizing the rotation of the magnetic levitation bearing.
