Description

Technical Field

[0001] The present invention relates to the technical field of bearing seats, and specifically to an adaptive self-aligning, stable vibration damping and noise reduction bearing seat device. Background Technique

[0002] A rotary table bearing seat is a special large and extra-large bearing seat that can accept comprehensive loads. It has the characteristics of compact structure, sensitive rotation, convenient installation and maintenance, etc. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the commonly said bearing seat. Usually, the bearing seat is located at both ends of the bearing to fix and support the bearing, so that a certain positional relationship is generated between other connecting parts and the bearing. Since mechanical vibration will inevitably occur during the operation of transmission machinery and equipment, the vibration mainly comes from the operation of mechanical transmission, the composition structure of the transmission shaft and the bearing, the connection and matching structure, etc. Moreover, the operation vibration of the mechanical equipment provided with a bearing seat also comes from the bearing seat itself. Negative vibration not only has an adverse effect on the operation of the machinery, but also has an adverse effect on the normal operation of the bearing seat. And the vibration of the bearing in turn will exacerbate the vibration of the mechanical operation, and the bearing seat is also easily damaged.

[0003] Chinese Patent Publication No. CN114941660A discloses a bearing seat for vibration damping and noise reduction, including a base main body. A first shock absorption device is installed at the bottom of the base main body, and a bearing seat mechanism is installed at the top of the base main body. Noise reduction mechanisms are provided inside the base main body and the bearing seat mechanism. A support mechanism is installed at the bottom of the first shock absorption device, and a second shock absorption device is installed at the top of the support mechanism. A dust prevention mechanism is installed outside the second shock absorption device, and an auxiliary device is fixedly provided outside the second shock absorption device. A bearing device is installed in cooperation with the inside of the bearing seat mechanism. By providing a shock absorption frame, a vertical rod and a connecting block, the effect that when the base main body moves downward under an impact force, the spring member cancels the impact force through the connecting block is achieved.

[0004] However, the existing devices have the following problems:

[0005] During use, the first shock absorption device is used in cooperation with the second shock absorption device for shock absorption, which can better cope with downward impacts. However, for the transmitted upward impacts, the shock absorption effect is not good, resulting in relatively large noise, and the shock absorption range cannot be adjusted according to specific situations, resulting in poor adaptive self-aligning effect and insufficient stability.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

This adaptive centering, stabilizing, shock-absorbing and noise-reducing bearing housing device is applied to the stable working scenario of the bearing housing. In this embodiment, by improving the structure of the bearing housing stability, it has the advantages of adaptive centering, stabilizing, shock-absorbing. Specifically, taking the bearing housing device as an example, so as a preferred solution in this embodiment, the bearing housing device is specifically an adaptive centering, stabilizing, shock-absorbing and noise-reducing bearing housing device, which can perform adaptive centering, stabilizing, shock-absorbing.

[0038] Please refer to Figures 1 to 8, the present invention provides a technical solution: an adaptive centering and stabilizing vibration and noise reduction bearing seat device, which is mainly applied to the scenario where the bearing seat works stably.

On the side of the connection assembly 6, there is a movable assembly 8. Inside the movable assembly 8, there is a stabilizing assembly 9.

[0040] The body assembly 1 includes a base 101. At the top of the base 101, there is a top plate 102 fixedly installed. Inside the base 101 and the top plate 102, there are fixing bolts 103 installed. Inside both the base 101 and the top plate 102, there are inner rings 104 fixedly installed. At the top of the top plate 102, there is a locking rod 105 fixedly installed. The base 101 and the top plate 102 are fixed by the fixing bolts 103. Appropriate inner rings 104 are fixedly installed inside. Bearings are assembled inside the inner rings 104, and the inner rings 104 are fixed again by the locking rod 105.

[0041] The adjustment assembly 2 includes an adjustment rod 201. One end of the adjustment rod 201 is fixedly connected to the top of the base 101. An adjustment spring 202 is sleeved on the surface of the adjustment rod 201. The side of the adjustment rod 201 is slidably connected to an adjustment block 203. When the base 101 vibrates, due to the vibration, it will move upward. At this time, the base 101 pushes the adjustment rod 201 to slide inside the adjustment block 203 and pulls the adjustment spring 202, which can reduce vibration and noise for the slight upward movement. Since the buffering effect for only downward movement is not good, it will generate noise for the upward impact. At the same time, by performing up and down shock absorption, the noise reduction effect is better, and the stability during use is higher, thereby reducing the wear during the use of the bearing.

[0042] The moving assembly 3 includes a moving rod 301. One end of the moving rod 301 is fixedly connected to the top of the adjustment block 203.

A square rod 403 is slidably connected inside the threaded rod 401. The rotation of the square rod 403 drives the threaded rod 401 to rotate, and the threaded rod 401 moves along the square rod 403. The threaded rod 401 rotates on the top of the adjusting block 203. Since the threaded rod 401 is threadedly connected to the driving body 402, the threaded rod 401 moves while rotating, thereby adjusting the moving range of the adjusting block 203 during the shock absorption and noise reduction process, and further enabling it to have the effect of self-adaptive adjustment of the center of the circle, so that the center of the circle moves within a certain range. The self-adaptive centering range is adjusted according to the application situation, making the centering process stable, with strong adaptability, and the shock absorption and noise reduction are stable.

The side of the shock absorption rod 501 is fixedly connected to the inside of the base 101. A shock absorption spring 502 is sleeved on the surface of the shock absorption rod 501. The top of the shock absorption block 503 is fixedly connected to the bottom of the base 101. A connecting spring 504 is fixedly installed at the bottom of the shock absorption block 503. A shock absorption body 505 is slidably connected to the side of the shock absorption block 503. The vibration of the base 101 pushes the shock absorption block 503 to move inside the shock absorption body 505, performing preliminary shock absorption while protecting the internal shock absorption spring 502, and the connecting spring 504 plays a supporting role for the shock absorption block 503. At this time, the base 101 slides along the direction of the shock absorption rod 501, thereby compressing the shock absorption spring 502 and damping the bearings inside the base 101. The up and down shock absorptions cooperate with each other, and the shock absorption rod 501 limits the base 101 to ensure a better shock absorption and noise reduction effect.

[0045] The connecting component 6 includes a connecting body 601. The top of the connecting body 601 is fixedly connected to the bottom of the shock absorption body 505. A connecting rod 602 is fixedly connected to the top of the connecting body 601. The side of the connecting rod 602 is slidably connected to the inside of the base 101. The base 101 moves along the direction of the connecting rod 602, and the connecting rod 602 plays a role of limiting and fixing.

[0046] The fixing component 7 includes a fixing body 701. The inside of the fixing body 701 is slidably connected to the bottom of the connecting body 601. A fixing hole 702 is opened inside the fixing body 701. The fixing body 701 is fixed by passing a fixing bolt through the fixing hole 702, thereby fixedly installing the base 101, and the connecting body 601 can slide inside the fixing body 701 for left and right buffering.

[0047] The movable component 8 includes a movable block 801. The side surface of the movable block 801 is fixedly connected to the side surface of the connecting body 601. A movable rod 802 is hinged to the side surface of the movable block 801. One end of the movable rod 802 is hinged to a movable body 803. When the connecting body 601 moves inside the fixed body 701, the connecting body 601 drives the movable block 801 fixed to its side to move, so that the movable block 801 drives the movable rod 802 connected to its side to change the angle, and the movable rod 802 drives the movable body 803 to move.

[0048] The stabilizing component 9 includes a stabilizing rod 901. The side surface of the stabilizing rod 901 is slidably connected to the inside of the movable body 803. A stabilizing spring 902 is sleeved on the surface of the stabilizing rod 901. Both ends of the stabilizing rod 901 are fixedly connected to the inside of the fixed body 701. When the movable body 803 moves along the direction of the stabilizing rod 901, at this time, the movable body 803 compresses the stabilizing spring 902 on its side, so that the stabilizing spring 902 performs left and right buffering and performs a certain self-aligning adjustment, and the use process is stable and reliable.

[0049] In summary, for this self-aligning, stable, shock-absorbing and noise-reducing bearing seat device, when in use:

[0050] 1. The fixing bolt passes through the fixing hole 702 to fix the fixed body 701, thereby fixedly installing the base 101. And the connecting body 601 can slide inside the fixed body 701. A locking rod 105 is fixedly installed on the top of the top plate 102. The base 101 and the top plate 102 are fixed by the fixing bolt 103. A suitable inner ring 104 is fixedly installed inside, a bearing is assembled inside the inner ring 104, and the inner ring 104 is fixed again by the locking rod 105;

[0051] 2. The rotation of the square rod 403 drives the threaded rod 401 to rotate, and the threaded rod 401 moves along the square rod 403. The threaded rod 401 rotates on the top of the adjusting block 203. Since the threaded rod 401 is threadedly connected to the driving body 402, the threaded rod 401 moves while rotating, thereby adjusting the moving range of the adjusting block 203 during shock absorption and noise reduction, and further enabling it to have the effect of self-adaptive adjustment of the center of the circle, so that the center of the circle moves within a certain range, and the self-aligning range is adjusted according to the application situation, making the self-aligning process stable, with strong adaptability, and stable shock absorption and noise reduction. The adjusting block 203 drives the moving rod 301 to slide inside the moving body 302, playing a role of stable limiting, making the adjusting block 203 more stable during the moving adjustment process;

[0052] 3. When the base 101 vibrates, it will move upward due to the vibration. At this time, the base 101 pushes the adjusting rod 201 to slide inside the adjusting block 203 and pulls the adjusting spring 202, which can reduce the vibration and noise of the slight upward movement. Since the buffering effect on the downward movement alone is not good, it will generate noise from the upward impact. By performing both upward and downward shock absorption, the noise reduction effect is better and the stability during use is higher, thereby reducing the wear of the bearing during use. When the base 101 vibrates, it pushes the shock-absorbing block 503 to move inside the shock-absorbing body 505, performing preliminary shock absorption while protecting the internal shock-absorbing spring 502, and the connecting spring 504 plays a supporting role for the shock-absorbing block 503. At this time, the base 101 slides along the direction of the shock-absorbing rod 501, thereby compressing the shock-absorbing spring 502 to shock-absorb the bearing inside the base 101. The upward and downward shock absorptions cooperate with each other, and the shock-absorbing rod 501 limits the base 101 to ensure a better shock-absorbing and noise-reducing effect. The base 101 moves along the direction of the connecting rod 602, and the connecting rod 602 plays a role in limiting and fixing;

[0053] 4. When the connecting body 601 moves inside the fixing body 701, the connecting body 601 drives the movable block 801 fixed on the side to move, so that the movable block 801 drives the movable rod 802 connected to the side to change the angle, and the movable rod 802 drives the movable body 803 to move. When the movable body 803 moves along the direction of the stabilizing rod 901, at this time, the movable body 803 compresses the stabilizing spring 902 on the side, so that the stabilizing spring 902 performs left and right buffering and performs a certain self-adaptive centering, and the use process is stable and reliable.
