Description

Technical Field

[0001] The utility model relates to the technical field of rotor sleeves, in particular to a high-strength generator rotor sleeve. Background Art

[0002] The generator rotor sleeve is a cylindrical mechanical part that is sleeved on the generator rotor shaft. The sleeve can reduce the wear between the rotor shaft and the bearing seat and protect the rotor shaft from damage.

[0003] The generator rotor sleeve in the prior art does not have the function of self-lubrication, and the staff needs to add lubricant to the sleeve by disassembling and assembling the sleeve. First, the process of disassembling and assembling the sleeve is cumbersome and time-consuming, requiring a lot of manpower and time costs. During the disassembly and assembly process, it is also necessary to ensure the matching accuracy of the sleeve with the rotor shaft and the bearing seat to avoid axis deviation and vibration problems caused by disassembly and assembly, which not only increases the complexity of the operation, but may also cause the generator to be damaged during the disassembly and assembly process. Secondly, the method of adding lubricant when disassembling and assembling the sleeve may cause uneven lubrication. During the disassembly and assembly process, the lubricant may not be evenly distributed on the surface of the sleeve, resulting in insufficient lubrication in some areas, thereby increasing friction and wear, which will not only reduce the efficiency of the generator, but may also shorten the service life of the sleeve and rotor shaft. Utility Model Content

[0004] In order to overcome the above technical problems, the purpose of the present utility model is to provide a high-strength generator rotor sleeve.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A high-strength generator rotor sleeve, comprising:

[0007] A shaft sleeve body, both ends of which are open;

[0008] Two sealing cover plates are respectively arranged at both ends of the shaft sleeve body;

[0009] Two assembly ports are respectively provided on the two sealing cover plates;

[0010] A plurality of lubrication structures are provided on the sleeve body;

[0011] Several adjustment structures are all arranged on the shaft sleeve body.

[0012] As a further solution of the present invention: the lubrication structure includes:

[0013] A slot is provided on the inner surface of the sleeve body;

[0014] a graphite block placed inside the slot;

[0015] A fixing plate is fixed on the side of the graphite block.

[0016] As a further solution of the present invention: the regulating structure includes:

[0017] A sink groove is provided on the outer surface of the sleeve body;

[0018] A threaded opening is provided on the wall of the sink, and the threaded opening is connected to the slot;

[0019] The adjusting bolt is threadedly sleeved in the threaded opening.

[0020] As a further solution of the present invention: the adjusting bolt is placed inside the sink.

[0021] As a further solution of the present invention, the side surface of the graphite block and the groove wall of the groove are in contact with each other.

[0022] As a further solution of the present invention: the graphite block has an arc-shaped structure.

[0023] Beneficial effects of the utility model:

[0024] 1. During the rotation of the generator rotor, the graphite blocks on the inner ring of the sleeve will rub against the rotor, generating graphite powder. This graphite powder acts as a lubricant, effectively reducing the friction and wear between the rotor and the sleeve. This not only extends the service life of the generator rotor and sleeve, but also improves the overall operating efficiency and stability of the generator.

[0025] 2. As the rotor continues to rotate, the graphite block will gradually be consumed, resulting in a gap between the rotor and the graphite block. However, the utility model designs adjustable bolts and fixing plates, allowing staff to easily adjust the position of the graphite block to ensure that the graphite block always maintains contact with the rotor. This design ensures the continuous production of graphite powder, thereby maintaining a good lubrication state between the sleeve and the rotor. At the same time, it also avoids the problems of insufficient lubrication and increased wear caused by the consumption of graphite blocks. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figure 1-4 As shown, a high-strength generator rotor sleeve includes a sleeve body 1, both ends of which are open; two sealing cover plates 2, respectively provided at both ends of the sleeve body 1; and two assembly openings 3, respectively provided on the two sealing cover plates 2.

[0034] The rotor sleeve also includes a plurality of lubrication structures, all of which are provided on the sleeve body 1. The lubrication structures include: a groove 41, which is provided on the inner surface of the sleeve body 1; a graphite block 42, which is placed inside the groove 41, and the side surface of the graphite block 42 fits with the groove wall of the groove 41, and the graphite block 42 has an arc-shaped structure; a fixing plate 43, which is fixed to the side surface of the graphite block 42. When the rotor passes through the sleeve body 1, the plurality of graphite blocks 42 on the inner ring of the sleeve body 1 will contact the rotor. During the rotation process, the rotor will continuously rub against the plurality of graphite blocks 42. The graphite powder generated during the friction process has a lubricating effect on the contact surface between the sleeve body 1 and the rotor. The sealing cover plates 2 provided at both ends of the sleeve body 1 are used to prevent the graphite powder from leaking out, so that the graphite powder is filled in the interior of the sleeve body 1.

[0035] The rotor sleeve also includes several adjustment structures, all of which are arranged on the sleeve body 1. The adjustment structures include: a groove 51, which is opened on the outer surface of the sleeve body 1; a threaded opening 52, which is opened on the groove wall of the groove 51, and the threaded opening 52 is connected to the slot 41; an adjusting bolt 53, which is threadedly sleeved in the threaded opening 52, and the adjusting bolt 53 is placed inside the groove 51. When the adjusting bolt 53 moves, it can push the fixed plate 43, so that the fixed plate 43 drives the graphite block 42 to move until the graphite block 42 presses the electronic rotor. The staff can adjust the position of the graphite block 42 by rotating the adjusting bolt 53, so that the graphite block 42 contacts the rotor again, ensuring that graphite powder can be continuously produced.

[0036] The working principle of this utility model:

[0037] When the high-strength generator rotor sleeve proposed by the present invention is used, after the staff assembles the sleeve body 1 in place, the generator rotor is passed through the sleeve body 1. When the rotor passes through the sleeve body 1, the multiple graphite blocks 42 on the inner ring of the sleeve body 1 will contact the rotor. During the rotation process, the rotor will continuously rub against the multiple graphite blocks 42. The graphite powder generated during the friction process has a lubricating effect on the contact surface between the sleeve body 1 and the rotor. The sealing cover plates 2 provided at both ends of the sleeve body 1 are used to prevent the graphite powder from leaking out, so that the graphite powder is filled in the interior of the sleeve body 1.

[0038] As the rotor rotates, the graphite block 42 will be continuously consumed, resulting in a gap between the graphite block 42 and the rotor. In this case, the graphite block 42 will not be able to rub against the rotor. Therefore, the staff can adjust the position of the graphite block 42 by turning the adjusting bolt 53, so that the graphite block 42 contacts the rotor again, ensuring that graphite powder can be continuously produced. Specifically, the staff can use a screwdriver to turn the adjusting bolt 53 to move the adjusting bolt 53. When the adjusting bolt 53 moves, it can push the fixing plate 43, so that the fixing plate 43 drives the graphite block 42 to move until the graphite block 42 presses the electronic rotor. The staff can determine whether the graphite block 42 presses the rotor by adjusting the position of the bolt 53 in the sink 51. In addition, the entire moving stroke of the adjusting bolt 53 is located inside the sink 51, ensuring that there is no protruding adjusting bolt 53 on the outer surface of the sleeve body 1, which is conducive to the assembly of the sleeve body 1.

[0039] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
