Description

Technical Field

[0001] The present invention relates to the technical field of gear strength detection, and more specifically, to an efficient gear strength detection device for a slewing speed reducer. Background Art

[0002] Slewing speed reducers are widely used in modern industry, especially in the fields of wind power generation, mining machinery, metallurgy, petrochemical, etc. As an important part of the mechanical transmission system, the core function of the slewing speed reducer is to reduce the speed of the high-speed motor and increase the output torque. The gear system of the speed reducer directly determines its transmission efficiency, stability and service life. As the core component of the slewing speed reducer, the gear bears huge and continuously changing loads. Therefore, the strength detection of the gear has become a key link to ensure the safe and reliable operation of the speed reducer. Among them, the tooth root is the place where bending fatigue damage is most likely to occur in the gear because the bending stress here is the largest. The tooth root is a key part when the gear transmits torque. If it breaks, the gear will fail. Therefore, the strength detection of the tooth root is crucial for judging the durability of the gear.

[0003] When the existing gear strength detection device detects the tooth root, it is necessary to apply pressure to each tooth root of the gear in turn and observe whether the tooth root breaks or cracks. Each time the angle of the gear is adjusted to test different tooth roots, the gear needs to be repositioned, resulting in low detection efficiency. Summary of the Invention

[0015] The beneficial effects of a high-efficiency gear strength detection device for a slewing speed reducer provided by the present invention include:

[0016] 1. By setting up a testing mechanism, the pallet and the gear under test are driven to move upward by the first electric telescopic rod, so that the gear under test meshes with the tooth groove part of the clamping seat, positioning the gear under test, and driving the positioning block to extend out of the sleeve shaft to longitudinally position the gear under test. Subsequently, the second motor can drive the bidirectional lead screw to rotate, driving the two moving seats to move closer, so that the tooth teeth on both sides are synchronously inserted into the tooth root of the gear under test, improving the detection efficiency. And the first motor drives the first lead screw to rotate, driving the pull plate and the pull rod to move backward, applying a pulling force to the tooth root of the gear under test to perform strength detection on it, and the magnitude of the pulling force can be observed in real time through the tensiometer, which is convenient to use.

[0017] 2. By setting up an adjustment mechanism, after testing one tooth root of the gear under test, the second motor drives the two moving seats to move away from each other, so that the tooth teeth disengage from the tooth root of the gear under test, and at the same time drives the first support rod and the inclined block to move synchronously, and drives the driving block to drive the support arm and the sleeve shaft to move upward, so that the gear under test disengages from the clamping seat, canceling the positioning of the gear under test. At the same time, the other moving seat drives the second support rod to move synchronously, driving the tooth block to move synchronously. When the tooth block meshes with the adjustment gear, it drives the rotating shaft and the sleeve shaft to rotate synchronously, realizing the angle adjustment of the gear under test, and then the strength detection of the next tooth root can be carried out, which is convenient to use and improves the detection efficiency.

[0018] 3. By setting up an observation mechanism, when the first contact and the second contact are closed, the vision camera works to take pictures of the detected tooth root, and an image processor is built into the detection table, which can identify the picture of the tooth root to judge whether there are damages or cracks on the tooth root. When it is recognized from the picture that there are damages or cracks on the tooth root, the second electric telescopic rod acts, driving the injection head to move towards the tooth root direction and abut against the side wall of the tooth root, squeezing the piston, compressing the fourth spring, and injecting the ink in the injection cylinder onto the surface of the tooth root through the first one-way valve, the connecting rod and the hollow part of the injection head, realizing the marking of the tooth root, which is convenient for subsequent classification of the gear under test.

[0031] Referring to Figures 1-9 As shown in the figure, the present invention provides a technical solution: an efficient gear strength detection device for a slewing speed reducer, including a detection table 1, a placement seat 2 and a clamping seat 3. The placement seats 2 are symmetrically and fixedly installed on the surface of the detection table 1. A clamping seat 3 is fixedly installed on the surface of the placement seat 2. Tooth grooves are formed in the inner wall of the clamping seat 3, and the tooth grooves are adapted to the gears to be tested for positioning the gears to be tested. A testing mechanism 4 is installed on the surface of the detection table 1 for detecting the strength of the gears to be tested. The testing mechanism 4 includes a sleeve shaft 401, a moving seat 410 and a pulling plate 412. The sleeve shaft 401 is movably installed on the surface of the detection table 1. A support plate 402 is slidably sleeved on the surface of the sleeve shaft 401 for placing the gears to be tested. A first electric telescopic rod 403 is fixedly installed in the inner cavity of the sleeve shaft 401. The telescopic end of the first electric telescopic rod 403 is fixedly connected to the support plate 402 for driving the support plate 402 to move up and down. A plug rod 404 is fixedly installed on the surface of the support plate 402. One end of the plug rod 404 is tapered. Positioning blocks 405 are symmetrically and slidably installed in the inner cavity of the sleeve shaft 401 for longitudinally positioning the gears to be tested. An inclined groove portion 406 is provided at one end of the positioning block 405. A connecting block 407 is fixedly installed on the surface of the positioning block 405. A first spring 408 is installed in the inner cavity of the sleeve shaft 401. One end of the first spring 408 is fixedly connected to the sleeve shaft 401, and the other end of the first spring 408 is fixedly connected to the connecting block 407 for driving the positioning block 405 to move towards the inner cavity of the sleeve shaft 401. A first spline tooth 409 is fixedly installed on the side wall of the sleeve shaft 401. During use, the gear to be tested is sleeved on the surface of the sleeve shaft 401 along the first spline tooth 409, so that the gear to be tested falls on the surface of the support plate 402. Subsequently, the first electric telescopic rod 403 is used to drive the support plate 402 and the gear to be tested to move up, so that the gear to be tested meshes with the tooth groove portion of the clamping seat 3 for positioning the gear to be tested. When the support plate 402 moves up, the plug rod 404 is driven to move up to squeeze the inclined groove portion 406, driving the positioning block 405 to extend out of the sleeve shaft 401 for longitudinally positioning the gear to be tested.

[0032] Referring to Figures 1-8As shown, in a preferred embodiment, the moving seat 410 is symmetrically and slidably mounted on the surface of the detection table 1. First mounting frames 411 are symmetrically and fixedly mounted on the surface of the moving seat 410. A pull plate 412 is slidably mounted between the two first mounting frames 411. A first lead screw 413 is rotatably mounted between the two first mounting frames 411. A first threaded block 414 is fixedly mounted on the surface of the pull plate 412. The first threaded block 414 is threadedly connected to the first lead screw 413. A first motor 415 is fixedly mounted on the side wall of the first mounting frame 411. The output end of the first motor 415 is fixedly connected to one end of the first lead screw 413. A pull rod 416 is fixedly mounted on the side wall of the pull plate 412. A tensiometer 417 is fixedly mounted at one end of the pull rod 416. A pull arm 418 is mounted at the other end of the tensiometer 417. A tooth 419 is fixedly mounted at one end of the pull arm 418. The tooth 419 is adapted to the gear to be tested. By inserting the tooth 419 into the tooth root of the gear to be tested and driving the first lead screw 413 to rotate through the first motor 415, the pull plate 412 and the pull rod 416 are driven to move backward, applying a pulling force to the tooth root of the gear to be tested to perform strength detection, and the magnitude of the pulling force can be observed in real time through the tensiometer 417, which is convenient for use.

[0033] Referring to Figures 1-8 As shown, in a preferred embodiment, drive arms 420 are fixedly mounted on the side walls of the two moving seats 410. A second threaded block 421 is fixedly mounted on the surface of the drive arm 420. A bidirectional lead screw 422 is rotatably mounted on the surface of the detection table 1. The bidirectional lead screw 422 is threadedly connected to the second threaded block 421. A second motor 423 is fixedly mounted on the surface of the detection table 1. The output end of the second motor 423 is fixedly connected to one end of the bidirectional lead screw 422 for driving the bidirectional lead screw 422 to rotate. By driving the bidirectional lead screw 422 to rotate through the second motor 423, the two moving seats 410 on both sides are driven to move closer, so that the teeth 419 on both sides are synchronously inserted into the tooth roots of the gear to be tested, improving the detection efficiency.

[0034] In a preferred embodiment, during use, the gear to be tested is sleeved on the surface of the sleeve shaft 401 along the first spline teeth 409, so that the gear to be tested falls on the surface of the support plate 402. Subsequently, the support plate 402 and the gear to be tested are driven to move upward by the first electric telescopic rod 403, so that the gear to be tested meshes with the tooth groove part of the clamping seat 3 to position the gear to be tested. When the support plate 402 rises, the insertion rod 404 is driven to move upward to squeeze the inclined groove part 406, and the positioning block 405 is driven to extend out of the sleeve shaft 401 to longitudinally position the gear to be tested. Subsequently, the second motor 423 can drive the bidirectional lead screw 422 to rotate, driving the two moving seats 410 to move closer, so that the tooth teeth 419 on both sides are synchronously inserted into the tooth roots of the gear to be tested, improving the detection efficiency. The first motor 415 drives the first lead screw 413 to rotate, driving the pull plate 412 and the pull rod 416 to move backward, applying a tensile force to the tooth roots of the gear to be tested to perform a strength test. The magnitude of the tensile force can be observed in real time through the tensiometer 417, which is convenient for use.

[0035] Referring to Figures 1-8 As shown, in a preferred embodiment, an adjusting mechanism 5 is installed on the surface of the detection table 1 for adjusting the angle of the gear to be tested. The adjusting mechanism 5 includes a rotating shaft 501, a support arm 504 and a driving block 505. The rotating shaft 501 is rotatably installed in the inner cavity of the detection table 1, and the surface of the rotating shaft 501 is inserted into the sleeve shaft 401. Second spline teeth 502 are symmetrically and fixedly installed on the side wall of the rotating shaft 501, and a second spline groove 503 is formed in the inner cavity of the sleeve shaft 401. The second spline teeth 502 mesh with the second spline groove 503. A support arm 504 is fixedly installed on the side wall of the sleeve shaft 401, and a driving block 505 is fixedly installed at one end of the support arm 504. The driving block 505 is wedge-shaped. A first support rod 506 is fixedly installed at the bottom of one of the moving seats 410, and an inclined block 507 is fixedly installed at one end of the first support rod 506 for driving the support arm 504 to move upward. A sliding rod 508 is fixedly installed in the inner cavity of the detection table 1, and a second spring 509 is sleeved on the surface of the sliding rod 508. One end of the second spring 509 is fixedly connected to the detection table 1, and the other end of the second spring 509 is fixedly connected to the support arm 504 for driving the support arm 504 to move downward, so that the driving block 505 is closely attached to the surface of the inclined block 507. After testing one of the tooth roots of the gear to be tested, the second motor 423 drives the two moving seats 410 to move away, so that the tooth teeth 419 are disengaged from the tooth roots of the gear to be tested. At the same time, the first support rod 506 and the inclined block 507 are driven to move synchronously, and the driving block 505 is driven to drive the support arm 504 and the sleeve shaft 401 to move upward, so that the gear to be tested is disengaged from the clamping seat 3, canceling the positioning of the gear to be tested.

[0036] Referring to Figures 1-8As shown, in a preferred embodiment, an adjustment gear 510 is fixedly installed on the surface of the rotating shaft 501 for adjusting the angle of the gear to be measured. At the bottom of another moving seat 410, an installation frame 511 is fixedly installed. A second support rod 512 is slidably installed in the inner cavity of the installation frame 511. A tooth block 513 is fixedly installed on the side wall of the second support rod 512. The tooth block 513 is adapted to the adjustment gear 510. When the second motor 423 drives the two moving seats 410 to move away from each other, the second support rod 512 is driven to move synchronously, and the tooth block 513 is driven to move synchronously. When the tooth block 513 meshes with the adjustment gear 510, the rotating shaft 501 and the sleeve shaft 401 are driven to rotate synchronously, realizing the angle adjustment of the gear to be measured, and then the strength detection of the next tooth root can be carried out; A guide rod 514 is fixedly installed on the side wall of the second support rod 512. A guide frame 515 is fixedly installed in the inner cavity of the detection table 1. A guide groove 516 is opened in the inner cavity of the guide frame 515. The guide rod 514 is inserted into the guide groove 516. A guide block 517 is slidably installed on the side wall of the guide frame 515. The surface of the guide block 517 is wedge-shaped. A third spring 518 is fixedly installed at the bottom of the guide block 517. The other end of the third spring 518 is fixedly connected to the guide frame 515 for driving the guide block 517 to move upward. When the second motor 423 drives the two moving seats 410 to move away from each other, the guide rod 514 is located at the upper end of the guide groove 516. At this time, the tooth block 513 and the adjustment gear 510 are on the same plane. Until the angle of the gear to be measured is adjusted, the guide rod 514 moves to the rightmost end of the guide groove 516 and falls to the lower end of the guide groove 516 under the action of gravity. At this time, the tooth block 513 and the adjustment gear 510 are no longer on the same plane. Therefore, when the second motor 423 drives the two moving seats 410 to move closer to each other again and drives the second support rod 512 to move leftward, the adjustment gear 510 will not be driven to rotate. And when the guide rod 514 contacts the guide block 517, it is squeezed to drive the guide block 517 to move downward until the guide rod 514 moves to the surface of the guide block 517, the third spring 518 resets, driving the guide block 517 to move upward and pushing the guide rod 514 back to the upper end of the guide groove 516. Repeat in turn until the strength detection of all tooth roots of the gear to be measured is completed.

[0037] In a preferred embodiment, after the test of one tooth root of the gear to be tested is completed, the second motor 423 drives the two moving seats 410 to move away from each other, so that the tooth 419 disengages from the tooth root of the gear to be tested. At the same time, it drives the first support rod 506 and the inclined block 507 to move synchronously, and drives the driving block 505 to drive the support arm 504 and the sleeve shaft 401 to move upward, so that the gear to be tested disengages from the clamping seat 3, canceling the positioning of the gear to be tested. At the same time, the other moving seat 410 drives the second support rod 512 to move synchronously, driving the tooth block 513 to move synchronously. When the tooth block 513 meshes with the adjusting gear 510, it drives the rotating shaft 501 and the sleeve shaft 401 to rotate synchronously, realizing the angle adjustment of the gear to be tested, and then the strength detection of the next tooth root can be carried out, which is convenient to use and improves the detection efficiency.

[0038] Refer to Figures 1-9 As shown in the figure, in a preferred embodiment, an observation mechanism 6 is installed on the surface of the detection table 1 for observing the tooth root after detection. The observation mechanism 6 includes a second mounting frame 601 and a vision camera 602. The second mounting frame 601 is fixedly installed on the surface of the detection table 1, and the vision camera 602 is installed on the side wall of the second mounting frame 601 for taking pictures of the teeth of the gear to be tested. A first contact 603 is fixedly installed in the inner cavity of the detection table 1, and a second contact 604 is fixedly installed on the surface of the support arm 504 for controlling the operation of the vision camera 602. After the test of one tooth root of the gear to be tested is completed, when the second motor 423 drives the two moving seats 410 to move away from each other and the angle of the gear to be tested is adjusted, the first contact 603 and the second contact 604 are closed. At this time, the vision camera 602 works to take pictures of the detected tooth root, and an image processor is built in the detection table 1 to identify the picture of the tooth root and judge whether there are damages or cracks on the tooth root.

When damage or cracks are identified at the tooth root from the picture, the second electric telescopic rod 605 acts to drive the injection head 609 to move towards the tooth root direction and abut against the side wall of the tooth root, squeezing the piston 607. The fourth spring 610 is compressed, and the ink in the syringe 606 is injected onto the surface of the tooth root through the first one-way valve 612, the connecting rod 608 and the hollow part of the injection head 609, realizing the marking of the tooth root and facilitating the subsequent classification of the gear to be measured.

[0040] In a preferred solution, during use, after testing one tooth root of the gear to be measured, the second motor 423 drives the two moving seats 410 to move away from each other. When adjusting the angle of the gear to be measured, the first contact 603 and the second contact 604 are closed. At this time, the vision camera 602 works to take a picture of the detected tooth root. And an image processor is built in the detection table 1, which can identify the picture of the tooth root to judge whether there is damage or cracks at the tooth root. When damage or cracks are identified at the tooth root from the picture, the second electric telescopic rod 605 acts to drive the injection head 609 to move towards the tooth root direction and abut against the side wall of the tooth root, squeezing the piston 607. The fourth spring 610 is compressed, and the ink in the syringe 606 is injected onto the surface of the tooth root through the first one-way valve 612, the connecting rod 608 and the hollow part of the injection head 609, realizing the marking of the tooth root and facilitating the subsequent classification of the gear to be measured.

[0041] Specifically, the working principle of the high-efficiency gear strength detection device for a slewing speed reducer is as follows: When in use, the gear to be tested is sleeved on the surface of the sleeve shaft 401 along the first spline tooth 409, and the gear to be tested is placed on the surface of the support plate 402. Subsequently, the support plate 402 and the gear to be tested are driven to move upward by the first electric telescopic rod 403, so that the gear to be tested meshes with the tooth groove part of the clamping seat 3 to position the gear to be tested. When the support plate 402 rises, it drives the insertion rod 404 to move upward, squeezes the inclined groove part 406, and drives the positioning block 405 to protrude from the sleeve shaft 401 to longitudinally position the gear to be tested. Subsequently, the second motor 423 can drive the bidirectional lead screw 422 to rotate, drive the two moving seats 410 to move closer, and make the two side teeth 419 synchronously insert into the tooth root of the gear to be tested to improve the detection efficiency. The first motor 415 drives the first lead screw 413 to rotate, drives the pull plate 412 and the pull rod 416 to move backward, applies a tensile force to the tooth root of the gear to be tested for strength detection, and the magnitude of the tensile force can be observed in real time through the tensile force gauge 417, which is convenient for use.

[0042] After the test of one tooth root of the gear to be tested is completed, the second motor 423 drives the two moving seats 410 to move away from each other, so that the teeth 419 disengage from the tooth root of the gear to be tested. At the same time, it drives the first support rod 506 and the inclined block 507 to move synchronously, and drives the driving block 505 to drive the support arm 504 and the sleeve shaft 401 to move upward, so that the gear to be tested disengages from the clamping seat 3 and cancels the positioning of the gear to be tested. At the same time, the other moving seat 410 drives the second support rod 512 to move synchronously, drives the tooth block 513 to move synchronously. When the tooth block 513 meshes with the adjusting gear 510, it drives the rotating shaft 501 and the sleeve shaft 401 to rotate synchronously, realizes the angle adjustment of the gear to be tested, and can then perform the strength detection on the next tooth root, which is convenient for use and improves the detection efficiency.

[0043] After the test of one tooth root of the gear to be tested is completed, when the second motor 423 drives the two moving seats 410 to move away from each other and the angle of the gear to be tested is adjusted, the first contact 603 and the second contact 604 are closed. At this time, the vision camera 602 works to take a picture of the tested tooth root. And an image processor is built in the detection table 1, which can identify the picture of the tooth root to judge whether there are damages or cracks on the tooth root. When it is identified from the picture that there are damages or cracks on the tooth root, the second electric telescopic rod 605 acts, drives the injection head 609 to move towards the tooth root direction, and abuts against the side wall of the tooth root to squeeze the piston 607, compresses the fourth spring 610, and injects the ink in the syringe 606 onto the surface of the tooth root through the first one-way valve 612, the connecting rod 608 and the hollow part of the injection head 609, realizing the marking of the tooth root, which is convenient for the subsequent classification of the gear to be tested.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
