A repair mechanism to reduce the vibration level of a gas generator

Abstract

This invention provides a repair mechanism for reducing the vibration level of a gas generator, relating to the field of gas generator technology. The invention includes a base with support rods evenly fixedly connected to its top. A semi-circular plate is fixedly connected to the top of each support rod. A centrifugal compressor shaft is mounted on the top of each semi-circular plate. When using the support device, the arc plate is manually rotated on the top of the semi-circular plate, thereby fitting the arc plate onto the surface of the centrifugal compressor shaft. Then, a fixing plate is manually slid along the inner wall of the connecting frame, sliding into the fixing groove. A first spring then pulls the fixing plate towards the semi-circular plate, effectively confining it within the fixing groove. This fixes the centrifugal compressor shaft to the top of the semi-circular plate. Other parts are supported by other staggered support rods and semi-circular plates, thus supporting all components of the gas generator on the surface of the base.

Description

Technical Field

[0001] This invention relates to the field of gas generator technology, and more particularly to a repair mechanism for reducing the vibration level of a gas generator. Background Technology

[0002] A repair device is a support for the gas generator in an aircraft engine during repairs. When using the repair device, the gas generator is placed on top of the base, allowing for fine-tuning of various parts of the gas generator. This facilitates the assembly of the components into the gas generator, ensuring that the connections between the components are more in line with specifications, and thus reducing the vibration level of the gas generator to some extent.

[0003] The inventors discovered in their daily work that the repair mechanism still has at least the following problems: When using the repair mechanism, the gas generator is placed on top of the base, which allows for fine-tuning of the various parts of the gas generator. This facilitates the assembly of the various components into a gas generator, making the connections between the components more compliant with specifications and reducing the vibration level of the gas generator to some extent. However, in actual use, when the various components of the gas generator are placed on top of the base, it is not possible to support all the components at the same time. This requires searching for each part individually, which to some extent affects the assembly efficiency of the gas generator. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a repair mechanism that reduces the vibration level of a gas generator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a repair mechanism for reducing the vibration level of a gas generator, comprising a base, support rods uniformly fixedly connected to the top of the base, and semicircular plates fixedly connected to the top of each support rod. A centrifugal compressor shaft is disposed on the top of the semicircular plate. A centrifugal impeller is disposed on the side of the centrifugal compressor shaft near the base. The centrifugal impeller is press-fitted with the centrifugal compressor shaft. An arc-shaped end tooth is disposed on the end of the centrifugal impeller away from the centrifugal compressor shaft. A gas turbine rotor is disposed on the end of the arc-shaped end tooth away from the centrifugal impeller. The gas turbine rotor is connected to the centrifugal impeller through the arc-shaped end tooth. A support device is disposed on the top of the base, and a support device is disposed on the side of the support rod near the centrifugal compressor shaft on the top of the base. The measuring device includes a support device comprising an arc plate, which is hinged to one side of a semi-circular plate near the centrifugal compressor shaft. The arc plate is fitted onto the surface of the centrifugal compressor shaft. A connecting frame is fixedly connected to one side of the semi-circular plate, and a fixing plate is slidably connected to the inner wall of the connecting frame. A fixing groove is formed on one side of the arc plate, and the inner wall of the fixing groove is fixedly connected to the end of the fixing plate away from the connecting frame. A round rod is fixedly connected to the inner wall of the connecting frame, and the end of the round rod near the connecting frame is fixedly connected to one side of the semi-circular plate. The round rod is slidably inserted through and inserted into one side of the fixing plate. A first spring is fitted onto the surface of the round rod, and one end of the first spring is fixedly connected to one side of the semi-circular plate. The end of the first spring near the round rod is fixedly connected to one side of the fixing plate.

[0006] The effect achieved by the above components is as follows: When using the support device, the arc plate is manually controlled to rotate at the top of the semicircular plate, thereby fitting the arc plate onto the surface of the centrifugal compressor shaft. Then, the fixing plate is manually controlled to slide on the inner wall of the connecting frame, thereby sliding the fixing plate into the inside of the fixing groove. Then, the fixing plate is pulled towards the semicircular plate by the first spring, thereby effectively restricting the fixing plate inside the fixing groove. In this way, the centrifugal compressor shaft can be fixed at the top of the semicircular plate. Other parts are supported by other interlaced support rods and the semicircular plate, thus supporting the various components of the gas generator on the surface of the base.

[0007] Preferably, a support bar is fixedly connected to the side of the semicircular plate near the base, and a bolt is threaded through the bottom of the support bar. A rubber block is fixedly connected to the end of the bolt near the support bar, and the end of the rubber block away from the bolt is located on the side of the centrifugal compressor shaft.

[0008] The effect achieved by the above components is that by manually rotating the bolt, the rubber block fixed at the bottom of the bolt is pressed against the bottom of the centrifugal compressor shaft, which can prevent the centrifugal compressor shaft from sliding on the top of the semi-circular plate to a certain extent.

[0009] Preferably, a rectangular plate is provided on the top of the base, and a first damping rod is uniformly fixedly connected to the bottom of the rectangular plate. The bottom of the first damping rod is fixedly connected to the top of the base. A second spring is sleeved on the surface of the first damping rod. One end of the second spring is fixedly connected to the top of the base, and the end of the second spring near the first damping rod is fixedly connected to the bottom of the rectangular plate.

[0010] The effect achieved by the above components is that the rectangular plate is pressed away from the base by the second spring, thereby setting the rectangular plate well at the bottom of the centrifugal impeller, so that the centrifugal impeller can be supported by the rectangular plate.

[0011] Preferably, a first threaded rod is threaded through the top of the rectangular plate, a rectangular strip is threaded through the bottom of the first threaded rod, the bottom of the rectangular strip is disposed on the top of the base, a limiting rod is slidably inserted through the top of the rectangular plate, and the bottom of the limiting rod is fixedly connected to the top of the rectangular strip.

[0012] The effect achieved by the above components is that the first threaded rod is manually controlled to rotate, thereby setting the rectangular bar on the top of the base. This can effectively restrict the rectangular plate to the bottom of the centrifugal impeller, and thus support the centrifugal impeller through the rectangular plate.

[0013] Preferably, the measuring device includes a sliding rod, and a limiting groove is formed on the top of the base near the centrifugal compressor shaft support rod. The top of the inner wall of the limiting groove is fixedly connected to the top of the sliding rod, and the bottom of the sliding rod is fixedly connected to the top of the base. A support frame is slidably sleeved on the surface of the sliding rod, and the support frame is slidably connected to the inner wall of the limiting groove. A limiting frame is fixedly connected to the top of the support frame, and a sliding strip is slidably connected to the inner wall of the limiting frame. An arrow is provided on one side of the sliding strip, and scale lines are evenly provided on one side of the sliding strip.

[0014] The effect achieved by the above components is as follows: when using the measuring device, the support frame is manually controlled to slide on the surface of the sliding rod, and then the sliding strip is controlled to slide on the inner wall of the limit frame. Then, the scale line is set on one side of the centrifugal compressor shaft. The rotor is tightened by the hydraulic device and the tensioning device. The length of the centrifugal compressor shaft before and after tensioning is measured, and its elongation is calculated. Thus, the relationship between the elongation and the vibration level can be well understood.

[0015] Preferably, a third spring is sleeved on the surface of the sliding rod, the bottom of the third spring is fixedly connected to the top of the base, and the end of the third spring near the sliding rod is fixedly connected to the bottom of the support frame.

[0016] The effect achieved by the above components is that the support frame is well supported by the third spring, which makes it easy to slide the support frame to the top of the limiting groove.

[0017] Preferably, a connecting plate is fixedly connected to the end of the sliding bar away from the arrow, and a second damping rod is fixedly connected to the side of the connecting plate near the sliding bar. The end of the second damping rod away from the connecting plate is fixedly connected to the side of the support frame. A fourth spring is sleeved on the surface of the second damping rod. One end of the fourth spring is fixedly connected to the side of the connecting plate near the sliding bar, and the end of the fourth spring near the second damping rod is fixedly connected to the side of the support frame.

[0018] The effect achieved by the above components is that the connecting plate is pulled closer to the support frame by the fourth spring, thereby effectively setting the sliding bar with scale lines on one side of the centrifugal compressor shaft.

[0019] Preferably, a locking groove is provided on one side of the sliding bar, and a second threaded rod is rotatably inserted into the inner wall of the locking groove. A connecting strip is threaded onto the surface of the second threaded rod, and the connecting strip is slidably connected to the inner wall of the locking groove. The end of the connecting strip away from the sliding bar is fixedly connected to the end of the arrow.

[0020] The effect achieved by the above components is: to manually control the rotation of the second threaded rod, thereby determining the position of the arrow measurement, so that the data can be obtained very accurately and to avoid large deviations in the data due to misalignment.

[0021] In this invention, by setting up a support device, when using the support device, the arc plate is manually controlled to rotate at the top of the semicircular plate, thereby fitting the arc plate onto the surface of the centrifugal compressor shaft. Then, the fixing plate is manually controlled to slide on the inner wall of the connecting frame, thereby sliding the fixing plate into the inside of the fixing groove. Then, the fixing plate is pulled towards the semicircular plate by the first spring, thereby effectively restricting the fixing plate inside the fixing groove. In this way, the centrifugal compressor shaft can be fixed at the top of the semicircular plate. Other parts are supported by other interlaced support rods and the semicircular plate, thus supporting the various components of the gas generator on the surface of the base.

Semicircular plates 3 are fixedly connected to the top of each support rod 2. A centrifugal compressor shaft 6 is mounted on the top of the semicircular plates 3. A centrifugal impeller 7 is mounted on the side of the centrifugal compressor shaft 6 closest to the base 1. The centrifugal impeller 7 is interference-fitted with the centrifugal compressor shaft 6. An arc-shaped end tooth 8 is provided at the end of the centrifugal impeller 7 away from the centrifugal compressor shaft 6. A gas turbine rotor 9 is mounted at the end of the arc-shaped end tooth 8 away from the centrifugal impeller 7. The gas turbine rotor 9 is connected to the centrifugal impeller 7 via the arc-shaped end tooth 8. A support device 4 is mounted on the top of the base 1. A measuring device 5 is mounted on the side of the support rods 2 near the centrifugal compressor shaft 6 on the top of the base 1. When using the repair mechanism, the gas generator is placed on the top of the base 1, allowing for fine-tuning of various parts of the gas generator. This facilitates the assembly of the components into a gas generator, ensuring that the connections between the components conform to specifications, thereby reducing the vibration level of the gas generator to a certain extent.

[0025] Reference Figure 3 and Figure 6The support device 4 includes an arc plate 401, which is hinged to one side of a semi-circular plate 3 near the centrifugal compressor shaft 6. The arc plate 401 is fitted onto the surface of the centrifugal compressor shaft 6. A connecting frame 402 is fixedly connected to one side of the semi-circular plate 3. A fixing plate 404 is slidably connected to the inner wall of the connecting frame 402. A fixing groove 405 is provided on one side of the arc plate 401. The inner wall of the fixing groove 405 is fixedly connected to the end of the fixing plate 404 away from the connecting frame 402. A round rod 403 is fixedly connected to the inner wall of the connecting frame 402. The end of the round rod 403 near the connecting frame 402 is fixedly connected to one side of the semi-circular plate 3. The round rod 403 is slidably inserted through one side of the fixing plate 404. A first spring 406 is fitted onto the surface of the round rod 403. One end of a spring 406 is fixedly connected to one side of a semicircular plate 3, and the end of the first spring 406 near the round rod 403 is fixedly connected to one side of a fixing plate 404. When using the support device 4, the arc plate 401 is manually controlled to rotate on the top of the semicircular plate 3, thereby fitting the arc plate 401 onto the surface of the centrifugal compressor shaft 6. Then, the fixing plate 404 is manually controlled to slide on the inner wall of the connecting frame 402, thereby sliding the fixing plate 404 into the fixing groove 405. Then, the fixing plate 404 is pulled towards the semicircular plate 3 by the first spring 406, thereby effectively restricting the fixing plate 404 inside the fixing groove 405. In this way, the centrifugal compressor shaft 6 can be fixed to the top of the semicircular plate 3. Other parts are fixed by other interlaced support rods. The base 1 is supported by a semi-circular plate 2 and a semi-circular plate 3, which supports the various components of the gas generator on the surface of the base 1. A support bar 407 is fixedly connected to the side of the semi-circular plate 3 near the base 1. A bolt 408 is threaded through the bottom of the support bar 407. A rubber block 409 is fixedly connected to the end of the bolt 408 near the support bar 407. The end of the rubber block 409 away from the bolt 408 is located on the side of the centrifugal compressor shaft 6. By manually rotating the bolt 408, the rubber block 409 fixed at the bottom of the bolt 408 is pressed against the bottom of the centrifugal compressor shaft 6, which can prevent the centrifugal compressor shaft 6 from sliding on the top of the semi-circular plate 3 to a certain extent. A rectangular plate 410 is provided on the top of the base 1. A first damping element is evenly fixed to the bottom of the rectangular plate 410. The bottom of the first damping rod 411 is fixedly connected to the top of the base 1. A second spring 412 is sleeved on the surface of the first damping rod 411. One end of the second spring 412 is fixedly connected to the top of the base 1. The end of the second spring 412 near the first damping rod 411 is fixedly connected to the bottom of the rectangular plate 410. The second spring 412 presses the rectangular plate 410 away from the base 1, thus effectively positioning the rectangular plate 410 at the bottom of the centrifugal impeller 7. In this way, the centrifugal impeller 7 can be supported by the rectangular plate 410. A first threaded rod 414 is threaded through the top of the rectangular plate 410. A rectangular strip 415 is threaded on the bottom of the first threaded rod 414. The bottom of the rectangular strip 415 is positioned at the top of the base 1.A limiting rod 413 is slidably inserted through the top of the rectangular plate 410. The bottom of the limiting rod 413 is fixedly connected to the top of the rectangular bar 415. The first threaded rod 414 is manually rotated, thereby positioning the rectangular bar 415 on top of the base 1. This effectively restricts the rectangular plate 410 to the bottom of the centrifugal impeller 7, thus supporting the centrifugal impeller 7.

[0026] Reference Figure 7 and Figure 8The measuring device 5 includes a sliding rod 502. A limiting groove 501 is formed on the top of the base 1 near the support rod 2 of the centrifugal compressor shaft 6. The top of the inner wall of the limiting groove 501 is fixedly connected to the top of the sliding rod 502, and the bottom of the sliding rod 502 is fixedly connected to the top of the base 1. A support frame 504 is slidably fitted onto the surface of the sliding rod 502. The support frame 504 is slidably connected to the inner wall of the limiting groove 501. A limiting frame 505 is fixedly connected to the top of the support frame 504. A sliding strip 506 is slidably connected to the inner wall of the limiting frame 505. An arrow 514 is provided on one side of the sliding strip 506, and scale lines 510 are evenly distributed on one side of the sliding strip 506. When using the measuring device 5… The support frame 504 is manually controlled to slide on the surface of the sliding rod 502, and then the sliding bar 506 is controlled to slide on the inner wall of the limit frame 505. This allows the centrifugal compressor shaft 6 with the scale line 510 to be positioned on one side. The rotor is tightened using a hydraulic and tensioning device. The length of the centrifugal compressor shaft 6 before and after tensioning is measured, and its elongation is calculated. This provides a good understanding of the relationship between elongation and vibration level. A third spring 503 is fitted onto the surface of the sliding rod 502. The bottom of the third spring 503 is fixedly connected to the top of the base 1. One end of the third spring 503 near the sliding rod 502 is fixedly connected to the bottom of the support frame 504. The third spring 503 effectively holds the support frame 504 in place. The support allows the support frame 504 to slide easily to the top of the limiting groove 501. A connecting plate 507 is fixedly connected to the end of the sliding bar 506 away from arrow 514. A second damping rod 508 is fixedly connected to the side of the connecting plate 507 near the sliding bar 506. The end of the second damping rod 508 away from the connecting plate 507 is fixedly connected to the side of the support frame 504. A fourth spring 509 is sleeved on the surface of the second damping rod 508. One end of the fourth spring 509 is fixedly connected to the side of the connecting plate 507 near the sliding bar 506, and the end of the fourth spring 509 near the second damping rod 508 is fixedly connected to the side of the support frame 504. The fourth spring 509 then moves the support closer to the... Pulling the connecting plate 507 in the direction of the frame 504 will properly position the sliding bar 506 with the scale line 510 on one side of the centrifugal compressor shaft 6. A locking groove 511 is provided on one side of the sliding bar 506. A second threaded rod 512 is rotatably inserted into the inner wall of the locking groove 511. A connecting bar 513 is threaded on the surface of the second threaded rod 512. The connecting bar 513 is slidably connected to the inner wall of the locking groove 511. The end of the connecting bar 513 away from the sliding bar 506 is fixedly connected to the end of the arrow 514. The second threaded rod 512 is manually rotated to measure the position of the arrow 514. This can obtain data very accurately and avoid large deviations in data due to misalignment.

[0027] Working principle: When using the repair mechanism, the gas generator is placed on top of the base 1, allowing for fine-tuning of various parts of the gas generator. This facilitates the assembly of the components into a complete gas generator, ensuring that the connections between the components conform to specifications and reducing the vibration level of the gas generator to some extent. When using the support device 4, the arc plate 401 is manually rotated on top of the semi-circular plate 3, allowing it to be fitted onto the surface of the centrifugal compressor shaft 6. Then, the fixing plate 404 is manually slid along the inner wall of the connecting frame 402, thus sliding the fixing plate 404 into the fixing groove 4. Inside the 05, the first spring 406 pulls the fixing plate 404 towards the semicircular plate 3, thus effectively confining the fixing plate 404 inside the fixing groove 405. This fixes the centrifugal compressor shaft 6 to the top of the semicircular plate 3. Then, the bolt 408 is manually rotated, causing the rubber block 409 fixed at the bottom of the bolt 408 to press against the bottom of the centrifugal compressor shaft 6. This can prevent the centrifugal compressor shaft 6 from sliding on the top of the semicircular plate 3 to a certain extent. The second spring 412 presses the rectangular plate 410 away from the base 1, and the first threaded rod 414 is manually rotated, thus... The rectangular bar 415 is positioned on top of the base 1, which effectively confines the rectangular plate 410 to the bottom of the centrifugal impeller 7. The rectangular plate 410 supports the centrifugal impeller 7. Other parts are supported by intersecting support rods 2 and semicircular plates 3, thus supporting all components of the gas generator on the surface of the base 1. When using the measuring device 5, the support frame 504 is manually slid across the surface of the sliding rod 502. The third spring 503 secures the support frame 504, allowing it to easily slide to the top of the limiting groove 501. Then, the sliding is controlled. The sliding bar 506 slides on the inner wall of the limiting frame 505. The fourth spring 509 pulls the connecting plate 507 towards the support frame 504, thus properly positioning the sliding bar 506 with the scale line 510 on one side of the centrifugal compressor shaft 6. The second threaded rod 512 is manually rotated to measure the position of the arrow 514. This allows for accurate data acquisition and avoids large deviations in data due to misalignment. The rotor is tightened by the hydraulic device and the tensioning device. The length of the centrifugal compressor shaft 6 before and after tensioning is measured, and its elongation is calculated, thus providing a good understanding of the relationship between elongation and vibration level.

[0028] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
