Description

Technical Field

[0001] The present invention relates to the technical field of shaft protection components, and specifically relates to a shaft fixing and alignment protection component for a hugging-shaft type shaft-driven generator. Background Art

[0002] A hugging-shaft type shaft-driven generator is a power generation device applied in the ship field, and the hugging-shaft type refers to an installation method and structural feature of the generator. During production, since shipyards generally do not have the conditions for testing generators, it is necessary to hoist the preliminarily assembled shaft-driven generator onto the ship for positioning and shaft alignment. When hoisting or reinstalling the rotor for the second time, because the shafting is still not fixed in place, it is easy to cause shaking and collision with the stator inside the motor. Therefore, a protection component is often borrowed to prevent the shaft and the rotor from moving around, ensure the gap between the rotor and the stator, and ensure the safety of the shafting.

[0003] When the traditional shaft-driven generator is hoisted onto the ship to reinstall the rotor and perform shaft alignment, since the shafting is still not fixed in place, the shaft and the rotor are prone to shaking along with the generator housing. And because the gap between the rotor and the stator is small, it will cause the rotor and the stator to collide, resulting in damage to the motor. For example, a shaft fixing and alignment protection component for a hugging-shaft type shaft-driven generator proposed in the utility model patent with the publication number of CN220673580U solves the above problems. During preliminary assembly, the operator sets two semi-circular wafers at the connection between the shaft and the body. The inner diameter of the circle formed after the two semi-circular wafers are butted is the same as the diameter of the shaft. At the same time, a retaining ring between the semi-circular wafer and the body is used to clamp the shaft. At the same time, a channel steel is installed on the side wall of the circumferential side of the hole of the generator shaft through a double-headed screw, and the flange at the end of the shaft and the channel steel are locked with bolts, so as to prevent the shaft from shaking during hoisting. After the generator is positioned, the screw and the channel steel are removed, and the inner diameter of the semi-circular wafer is expanded using a machine tool and reinstalled. The operation process is cumbersome, and during the process of limiting or canceling the limit of the shaft, the bolts need to be rotated repeatedly, with low operation efficiency and poor flexibility;

[0004] When installing the shaft-driven generator, it is necessary to ensure precise alignment with components such as the transmission shaft and the coupling. The body of the shaft-driven generator is usually directly fixed to the floor of the ship's cabin using bolts. And because screw holes are pre-opened on the ship's cabin, if there are slight deviations in the position of the screw holes or the dimensions of equipment such as the shaft-driven generator and the engine during installation, it will cause the shaft of the generator to be difficult to precisely align with other transmission shafts. At this time, it is necessary to repeatedly disassemble and reinstall the bolts, or form and open screw holes on the floor of the ship's cabin, with a cumbersome operation process and poor flexibility;

[0005] When installing a shaft-driven generator, due to height differences in the installation positions caused by different locations or hull structures of the ship, in order to ensure the correct connection between the rotating shaft of the generator and the transmission shaft or other equipment, a base is usually installed at the bottom of the generator using bolts. However, since different hull structures are different, bases of different heights need to be replaced, resulting in poor practicability. Moreover, during the operation of the equipment, due to temperature changes or loads, slight deformations may occur, while the height of the base remains constant, which is likely to cause vibration or damage to the shaft.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners

[0034] As Figures 1-4As shown, a shaft fixing and centering protection assembly of a shaft-holding shaft-belt generator described in the present invention comprises a generator body 1, a mounting structure 2 mounted on the generator body 1, a protection structure 3 connected to the mounting structure 2, a shaft-belt generator shaft 4 mounted on the generator body 1, a first adjustment structure 5 arranged at the bottom of the generator body 1, a height adjustment structure 6 connected to the first adjustment structure 5, and a second adjustment structure 7 matched with the height adjustment structure 6; the mounting structure 2 comprises an end cover 201 and three ears 202 fixedly connected to the edge of the end cover 201, the end of the generator body 1 abuts against the end cover 201, the end cover 201 is matched with the protection structure 3, the protection structure 3 comprises a connecting seat 301 and a rotating seat 302 arranged at the center of the connecting seat 301, the outer side of the end cover 201 is fixedly connected to the connecting seat 301, a retaining frame 303 is provided between the connecting seat 301 and the rotating seat 302, a plurality of balls 304 are sleeved on the retaining frame 303, and the balls 304 is rollingly connected with the inner wall of the connecting seat 301 and the rotating seat 302. The center position of the rotating seat 302 is engaged with a limiting sleeve 307. The top of the limiting sleeve 307 is slidably connected with two limiting blocks 308. A tension spring 309 is fixedly connected between the limiting blocks 308 and the inner wall of the limiting sleeve 307. A shaft-belt generator shaft 4 is provided between the two limiting blocks 308. The shaft-belt generator shaft 4 passes through the limiting sleeve 307. The top of the limiting sleeve 307 is threadedly connected with two knobs 3 11. The inner end of the knob 311 abuts against the limit block 308. A seal 305 is engaged between the bottom surface of the connecting seat 301 and the rotating seat 302. A gray ring 306 is engaged between the top surface of the connecting seat 301 and the rotating seat 302. A rubber pad 310 is fixedly connected to the side of the limit block 308 close to the shaft generator shaft 4. The rubber pad 310 abuts against the shaft generator shaft 4. The limit sleeve 307 is a hexagonal prism structure, and the limit block 308 is an arc structure.Before hoisting the shaft-belt generator to the cabin for installation, it is necessary to first limit the shaft-belt generator shaft 4 (refer to the shaft-belt generator shaft in the patent with announcement number CN220673580U) preliminarily installed on the generator body 1 to avoid collision between the rotor connected thereto and the stator inside the generator due to shaking during hoisting or secondary assembly. First, the shaft-belt generator shaft 4 connected to the rotor is installed inside the generator body 1. Since the gap between the rotor and the stator is small, in order to avoid collision between the two, it is only necessary to use bolts to fix a connecting seat 301 and other components installed thereon at the designated screw holes on the outside of the end cover 201, and then rotate at the same time. The knob 311 at the end of the limit sleeve 307 is threadedly connected to the limit sleeve 307, so that the knob 311 moves toward the inside of the limit sleeve 307 and contacts the limit block 308, driving the limit block 308 to slide in the direction of the shaft generator shaft 4 and stretching the tension spring 309 until the two limit blocks 308 clamp the shaft generator shaft 4. Since the rubber pad 310 is fixed on the side of the limit block 308 close to the shaft generator shaft 4, the friction between the shaft generator shaft 4 and the shaft generator shaft 4 is increased, and the firmness is improved. At this time, the shaft generator shaft 4 is effectively fixed to prevent it from shaking during the lifting process. A tension spring 309 is provided between the inner walls of 7, so that when the knob 311 is rotated to the initial position, the limit block 308 can be retracted into the inside of the limit sleeve 307, so as not to block the movement of the shaft-belt generator shaft 4. Moreover, since the limit sleeve 307 is a hexagonal prism and is engaged with the rotating seat 302, when the internal parts of the limit sleeve 307 are damaged, it is convenient to dismantle it as a whole for repair or replacement, and the flexibility is strong. When the generator body 1 is calibrated for the shaft system, the generator body 1 drives the shaft-belt generator shaft 4 to rotate, the shaft-belt generator shaft 4 drives the limit sleeve 307 to rotate, and the limit sleeve 307 drives the rotating seat 302 to rotate inside the connecting seat 301, thereby realizing the shaft-belt generator. The position of the machine shaft 4 is always limited during its rotation, avoiding the problem of collision between the rotor and the stator caused by vibration during the alignment of the shaft system, and the practicability is strong. Since the ball 304 is provided between the rotating seat 302 and the connecting seat 301 through the retaining frame 303, the friction between the rotating seat 302 and the connecting seat 301 is reduced, which can effectively reduce the friction resistance of the rotating parts during the movement and improve the mechanical efficiency. The bottom surfaces of the connecting seat 301 and the rotating seat 302 are engaged with a seal 305 to avoid dust from entering, and a gray ring 306 is provided between the top surfaces of the two, which not only ensures the sealing performance, but also plays a role in reducing friction, and has strong wear resistance. ;

[0035] Specifically, Figure 1 , Figure 2 and Figure 7As shown, the attachment ear 202 is fixedly connected to the generator body 1 by bolts, and the end of the generator body 1 away from the end cover 201 is fixedly connected with a heat dissipation cover 203; the end cover 201 is covered, so that the attachment ear 202 at the edge of the end cover 201 is aligned with the corresponding position on the generator body 1, and then locked by bolts, which has strong firmness. At the same time, the other end of the generator body 1 is provided with a heat dissipation cover 203, which enhances the overall heat dissipation performance.

[0036] Specifically, Figure 1 and Figures 5-9As shown in the figure, the first adjustment structure 5 includes a bottom plate 501 and a first lead screw 502 rotatably connected to the bottom plate 501. The bottom of the generator body 1 is provided with the bottom plate 501. Two guide rails 503 are slidably arranged on the bottom plate 501. One of the guide rails 503 is threadedly connected to the first lead screw 502. Both ends of the guide rail 503 are fixedly connected with a first rack 504. Two mounting brackets 505 are slidably connected between the two guide rails 503. Both ends of the mounting bracket 505 are fixedly connected with a second rack 506. The second rack 506 meshes with the adjacent first rack 504. A connecting plate 507 is fixedly connected between the two mounting brackets 505. A second lead screw 508 is threadedly connected to the center position of the connecting plate 507. The bottom of the second lead screw 508 is rotatably connected to a connecting frame 510. Two rollers 511 are rotatably connected to the connecting frame 510. The mounting bracket 505 is in a "U" - shaped structure. The top of the second lead screw 508 is fixedly connected with a rotating block 509. During the installation of the generator body 1, when the positions of the screw holes reserved on the cabin do not correspond or there are differences in the dimensions of the equipment, resulting in difficulty in accurately aligning the shaft - driven generator shaft 4 with other drive shafts, if it is necessary to adjust the lateral position of the generator body 1, just rotate the rotating block 509 at the bottom of the generator body 1 first. Then the rotating block 509 drives the second lead screw 508 to rotate. Since the second lead screw 508 is threadedly connected to the connecting plate 507 and is rotatably connected to the connecting frame 510 at the bottom, the second lead screw 508 drives the connecting frame 510 to move downward. When the two rollers 511 on the connecting frame 510 abut against the bottom plate 501 and jack up the connecting plate 507 and the two mounting brackets 505 by a certain distance until the second racks 506 at both ends of the mounting bracket 505 no longer mesh with the first racks 504 at the bottom, at this time, the generator body 1 can be pushed to freely move on the two guide rails 503 to adjust the position. After adjusting to the appropriate position, rotate the rotating block 509 on the second lead screw 508 in the reverse direction to make the rollers 511 at the bottom no longer abut against the bottom plate 501. At this time, the second racks 506 at both ends of the mounting bracket 505 mesh with the corresponding positions on the first racks 504 again, effectively fixing the positions of the mounting bracket 505 and the generator body 1 above. Then, use a hex wrench to rotate the first lead screw 502 on the bottom plate 501. The first lead screw 502 drives the guide rail 503 connected to it to move horizontally freely. At the same time, this guide rail 503 drives the other guide rail 503 to move. Then the two guide rails 503 drive the generator body 1 above to move horizontally, so as to achieve the purpose of accurately adjusting the lateral position of the generator body 1. The operation is simple, avoiding the problem of repeatedly installing and disassembling bolts when adjusting the position and improving the operation efficiency.

[0037] Specifically, as Figure 1 and Figures 5-9As shown in the figure, the height adjustment structure 6 includes a first guide post 601 and an elevation frame 602 slidably connected to the first guide post 601. Both ends of one of the mounting brackets 505 are fixedly connected to the first guide post 601, and both ends of the other mounting bracket 505 are fixedly connected to another first guide post 601 and a second guide post 607 respectively. The second guide post 607 is slidably connected to the adjacent elevation frame 602. An installation plate 603 is provided above each of the two elevation frames 602. A second adjustment structure 7 is fitted on the installation plate 603. A connecting bar 604 is slidably connected between the two installation plates 603. A support frame 605 is fixedly connected to the connecting plate 507. A third lead screw 606 is rotatably connected to the support frame 605. The third lead screw 606 is threadedly connected to the connecting bar 604. The support frame 605 is in a "U" - shaped structure. Another rotating block 509 is fixedly connected to the bottom of the third lead screw 606; when it is necessary to adjust the height of the generator body 1, just rotate the other rotating block 509 at the bottom of the generator body 1. This rotating block 509 drives the third lead screw 606 to rotate on the support frame 605, and at the same time drives the connecting bar 604 and the two installation plates 603 to move up and down. The two installation plates 603 drive the generator body 1 installed on the top through the fixing plate 704 to move up and down, so as to quickly adjust the height of the generator body 1, which is convenient for the accurate alignment of the shaft - driven generator shaft 4 and other transmission shafts. The operation is simple and the operation efficiency is high. At the same time, during the up - and - down movement of the two installation plates 603, the installation plate 603 drives the elevation frame 602 at the bottom to move up and down along the three first guide posts 601 and one second guide post 607. And since a quadrilateral is formed between the first guide post 601 and the second guide post 607, the stability during the up - and - down movement of the elevation frame 602 and the generator body 1 is enhanced, and the flexibility is strong.

[0038] Specifically, as Figure 1 and Figures 5-9As shown, the second adjustment structure 7 includes a guide rod 701 and a connection block 702 slidably connected to the guide rod 701. One of the elevation adjustment frames 602 is fixedly connected with the guide rod 701, and the connection block 702 is slidably connected between the inner walls of the elevation adjustment frames 602. A fourth lead screw 703 is rotatably connected to the other elevation adjustment frame 602. Two other connection blocks 702 are threadedly connected to the fourth lead screw 703. An installation plate 603 is fixedly connected between two adjacent connection blocks 702. Two fixing plates 704 are fixedly connected to the bottom of the generator body 1, and the fixing plates 704 are fixedly connected to the installation plate 603. When it is necessary to adjust the longitudinal position of the generator body 1, only need to use a hex wrench to rotate the fourth lead screw 703 on one of the elevation adjustment frames 602. Then, the fourth lead screw 703 drives the adjacent installation plate 603 to move longitudinally freely through the two connection blocks 702. Relative sliding occurs between the installation plate 603 and the connection bar 604. At the same time, since the generator body 1 is fixedly connected between the two installation plates 603, the installation plate 603 drives the other installation plate 603 to move longitudinally. At the same time, the two connection blocks 702 at the bottom of the other installation plate 603 slide along the guide rod 701. The setting of the guide rod 701 enhances the overall stability. At this time, the adjustment of the longitudinal position of the generator body 1 is completed, and the operation is simple and convenient.

[0039] When the present invention is in use, before hoisting the shaft generator to the cabin for installation, it is necessary to first limit the shaft of the shaft generator 4 (the shaft of the shaft generator in the patent with the reference publication number CN220673580U) initially installed on the generator body 1 to avoid bumping between the rotor connected thereto and the stator inside the generator due to shaking during hoisting or secondary assembly. First, the shaft of the shaft generator 4 connected with the rotor is installed inside the generator body 1, and then the end cover 201 is covered, so that the lugs 202 at the edge of the end cover 201 are aligned with the corresponding positions on the generator body 1, and then tightened with bolts, which has strong firmness. At the same time, a heat dissipation cover 203 is provided at the other end of the generator body 1, enhancing the overall heat dissipation performance. Since the gap between the rotor and the stator is small, in order to avoid bumping between the two, only a connecting seat 301 and other components installed on it are fixed with bolts at the specified screw holes outside the end cover 201, and then the knob 311 at the end of the limiting sleeve 307 is rotated simultaneously. Since the knob 311 is threadedly connected with the limiting sleeve 307, the knob 311 moves towards the inside of the limiting sleeve 307 and abuts against the limiting block 308, driving the limiting block 308 to slide towards the shaft of the shaft generator 4 and stretching the tension spring 309 until the two limiting blocks 308 clamp the shaft of the shaft generator 4. And because a rubber pad 310 is fixed on the surface of the limiting block 308 close to the shaft of the shaft generator 4, the friction force with the shaft of the shaft generator 4 is increased, improving the firmness. At this time, the shaft of the shaft generator 4 is effectively fixed to avoid shaking during hoisting. And because a tension spring 309 is provided between the limiting block 308 and the inner wall of the limiting sleeve 307, when the knob 311 is rotated to the initial position, the limiting block 308 can contract into the limiting sleeve 307, thus not blocking the movement of the shaft of the shaft generator 4. And because the limiting sleeve 307 is hexagonal prism-shaped and is engaged with the rotating seat 302, when the internal parts of the limiting sleeve 307 are damaged, it is convenient to remove the whole for repair or replacement, with strong flexibility. When the shaft alignment of the generator body 1 is carried out, the generator body 1 drives the shaft of the shaft generator 4 to rotate, the shaft of the shaft generator 4 drives the limiting sleeve 307 to rotate, and the limiting sleeve 307 drives the rotating seat 302 to rotate inside the connecting seat 301, thus realizing the continuous limitation of the position of the shaft of the shaft generator 4 during its rotation, avoiding the problem of bumping between the rotor and the stator due to vibration during the shaft alignment process, with strong practicability. And because a ball 304 is provided between the rotating seat 302 and the connecting seat 301 through a cage 303, the friction force between the rotating seat 302 and the connecting seat 301 is reduced, which can effectively reduce the friction resistance of the rotating parts during movement and improve the mechanical efficiency. And a seal 305 is engaged with the bottom surfaces of the connecting seat 301 and the rotating seat 302 to prevent dust from entering, and a Gleitring 306 is provided between their top surfaces, which not only ensures the sealing performance but also plays a role in reducing the friction force, and at the same time has strong wear resistance;

[0040] During the installation of the generator body 1, when the positions of the reserved screw holes on the cabin do not correspond or there are differences in the dimensions of the equipment, resulting in difficulty in accurately aligning the shaft-driven generator shaft 4 with other transmission shafts, if it is necessary to adjust the lateral position of the generator body 1, only need to first rotate the rotating block 509 at the bottom of the generator body 1, and then the rotating block 509 drives the second lead screw 508 to rotate. Since the second lead screw 508 is threadedly connected to the connecting plate 507 and is rotatably connected to the connecting frame 510 at the bottom, the second lead screw 508 drives the connecting frame 510 to move downward. When the two rollers 511 on the connecting frame 510 abut against the bottom plate 501 and jack up the connecting plate 507 and the two mounting brackets 505 by a certain distance until the second racks 506 at both ends of the mounting bracket 505 no longer mesh with the first rack 504 at the bottom, at this time, the generator body 1 can be pushed to freely move on the two guide rails 503 to adjust the position. After adjusting to the appropriate position, rotate the rotating block 509 on the second lead screw 508 in the reverse direction so that the bottom rollers 511 no longer abut against the bottom plate 501. At this time, the second racks 506 at both ends of the mounting bracket 505 mesh with the corresponding positions on the first rack 504 again, effectively fixing the positions of the mounting bracket 505 and the generator body 1 above. Then, use a hex wrench to rotate the first lead screw 502 on the bottom plate 501, drive the guide rail 503 connected to it to move horizontally freely through the first lead screw 502, and at the same time, this guide rail 503 drives the other guide rail 503 to move, so that the two guide rails 503 drive the generator body 1 above to move horizontally, thus achieving the purpose of accurately adjusting the lateral position of the generator body 1. The operation is simple, avoiding the problem of repeatedly installing and disassembling bolts when adjusting the position, and improving the operation efficiency;

[0041] When it is necessary to adjust the height of the generator body 1, only need to rotate another rotating block 509 at the bottom of the generator body 1. This rotating block 509 drives the third lead screw 606 to rotate on the support frame 605, and at the same time drives the connecting strip 604 and the two mounting plates 603 to move up and down. The two mounting plates 603 drive the generator body 1 installed on the top through the fixing plate 704 to move up and down, thus quickly adjusting the height of the generator body 1, facilitating the accurate alignment of the shaft-driven generator shaft 4 with other transmission shafts. The operation is simple and the operation efficiency is high. At the same time, during the up and down movement of the two mounting plates 603, the mounting plates 603 drive the height-adjusting frame 602 at the bottom to move up and down along the three first guide posts 601 and one second guide post 607. And since the first guide posts 601 and the second guide post 607 form a quadrilateral, the stability during the up and down movement of the height-adjusting frame 602 and the generator body 1 is enhanced, and the flexibility is strong;

[0042] When it is necessary to adjust the longitudinal position of the generator body 1, just use a hex wrench to rotate the fourth lead screw 703 on one of the elevation frames 602. Then, the fourth lead screw 703 drives the adjacent mounting plate 603 to move longitudinally freely through two connecting blocks 702. Relative sliding occurs between the mounting plate 603 and the connecting bar 604. At the same time, since the generator body 1 is fixedly connected between the two mounting plates 603, the mounting plate 603 drives the mounting plate 603 on the other side to move longitudinally. At the same time, the two connecting blocks 702 at the bottom of the mounting plate 603 on the other side slide along the guide rod 701. The setting of the guide rod 701 enhances the overall stability. At this time, the adjustment of the longitudinal position of the generator body 1 is completed, and the operation is simple and convenient.
