Description

Technical Field

[0001] This utility model relates to the field of pump bearing technology, specifically to a pump bearing sleeve with noise reduction function. Background Technology

[0002] During pump operation, bearings are key components, and their operating condition directly affects the pump's performance and service life.

[0003] However, during operation, traditional pump bearings generate significant noise due to vibration and friction between their components. This noise not only disrupts the working environment and affects the physical and mental health of workers, but prolonged exposure to high noise levels can also damage the pump's internal structure, reducing its reliability and stability.

[0004] To address the aforementioned issues, we propose a pump bearing sleeve with noise reduction capabilities. Utility Model Content

[0005] The purpose of this invention is to provide a pump bearing sleeve with noise reduction function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pump bearing sleeve with noise reduction function, comprising an outer ring, a rolling cage, a first noise reduction and vibration damping ring, a second noise reduction and vibration damping ring, and an inner ring; The second noise reduction and vibration damping ring is sleeved on the outer circumferential side of the inner ring; the rolling retainer is sleeved on the outer circumferential side of the second noise reduction and vibration damping ring; the first noise reduction and vibration damping ring is sleeved on the outer circumferential side of the rolling retainer; the outer ring is sleeved on the outer circumferential side of the first noise reduction and vibration damping ring.

[0007] Preferably, a guide groove is provided on the inner circumferential side of the outer ring; the first noise reduction and vibration damping ring is slidably connected in the guide groove.

[0008] Preferably, the inner side of the guide groove is provided with a clearance compensation ring; the inner side of the clearance compensation ring is in contact with the outer side of the first noise reduction and vibration damping ring.

[0009] Preferably, the rolling cage includes a cage and a plurality of rolling elements; the plurality of rolling elements are rotatably connected within the cage.

[0010] Preferably, the first noise reduction and vibration damping ring includes a first grid frame and a plurality of first damping components; the first grid frame is internally connected to the plurality of first damping components; The second noise reduction and vibration damping ring includes a second space frame and multiple second damping components; multiple second damping components are connected inside the second space frame.

[0011] Preferably, dust covers are provided on both ends of the outer ring; the dust covers are fastened between the end faces of the outer ring and the end faces of the inner ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Significant noise reduction effect: By setting up a first noise reduction and vibration damping ring and a second noise reduction and vibration damping ring, the vibration energy is absorbed and dispersed by the damping components, effectively reducing the noise generated by vibration during bearing operation. At the same time, the design of the guide groove and clearance compensation ring of the outer ring reduces the internal clearance and wobble of the bearing, further reducing noise.

[0013] Improved stability: The proper connection and coordination between components, along with the installation of dust covers, ensures the stability of the bearings during operation. This reduces component damage caused by vibration and friction, extends bearing life, and improves pump operational reliability.

[0014] Improved working environment: Reduced noise generated by bearing operation creates a relatively quiet working environment for staff, which is beneficial to protecting their physical and mental health. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a pump bearing sleeve with noise reduction function, including an outer ring 1, a rolling cage 2, a first noise reduction and vibration damping ring 3, a second noise reduction and vibration damping ring 4, and an inner ring 5. This utility model adopts multi-structure integration, and can not only be used as a bearing on its own, but also as a bearing sleeve fitted into existing bearings.

[0019] The second noise-reducing and vibration-damping ring 4 is fitted onto the outer circumferential side of the inner ring 5. The rolling retainer 2 is fitted onto the outer circumferential side of the second noise-reducing and vibration-damping ring 4. The first noise-reducing and vibration-damping ring 3 is fitted onto the outer circumferential side of the rolling retainer 2. The outer ring 1 is fitted onto the outer circumferential side of the first noise-reducing and vibration-damping ring 3. This nested assembly method allows the components to cooperate with each other and work together to reduce noise and vibration.

[0020] The outer ring 1 has a guide groove 11 on its inner circumferential side, and the first noise reduction and vibration damping ring 3 is slidably connected in the guide groove 11. The guide groove 11 provides a stable motion track for the first noise reduction and vibration damping ring 3, so that the first noise reduction and vibration damping ring 3 can slide smoothly during operation, reducing vibration and noise caused by shaking.

[0021] The inner side of the guide groove 11 is provided with a clearance compensation ring 12, and the inner side of the clearance compensation ring 12 is in contact with the outer side of the first noise reduction and vibration damping ring 3. The clearance compensation ring 12 can automatically compensate for the clearance generated during the operation of the bearing, avoid the aggravation of vibration and noise caused by excessive clearance, and further improve the stability and noise reduction effect of the bearing.

[0022] The rolling cage 2 includes a cage 21 and a plurality of rolling elements 22, with the rolling elements 22 rotatably connected within the cage 21. Under the constraint of the cage 21, the rolling elements 22 can roll smoothly between the inner ring 5 and the outer ring 1, realizing the rotation function of the bearing. Simultaneously, the design of the cage 21 ensures the stability of the relative positions of the rolling elements 22, reducing collisions and friction during rolling and lowering noise.

[0023] The first noise reduction and vibration damping ring 3 includes a first grid frame 31 and a plurality of first damping components 32, and the first grid frame 31 is connected to the plurality of first damping components 32.

[0024] The second noise reduction and vibration damping ring 4 includes a second grid frame 41 and a plurality of second damping components 42, wherein the second grid frame 41 is connected to a plurality of second damping components 42.

[0025] The first space frame 31 and the second space frame 41 provide mounting frames for the first damping element 32 and the second damping element 42, allowing multiple first damping elements 32 and multiple second damping elements 42 to be evenly distributed inside the bearing sleeve. The first damping element 32 and the second damping element 42 can absorb and disperse the vibration energy generated during bearing operation, reduce the transmission of vibration, and thus effectively reduce noise.

[0026] When the first damping element 32 is rotatably connected to the first mesh frame 31 and the second damping element 42 is rotatably connected to the second mesh frame 41, neither the first mesh frame 31 nor the second mesh frame 41 rotates. Therefore, the clearance compensation ring 12 is made of damping rubber with high friction, which can increase friction and provide good buffering effect.

[0027] When the first damping component 32 is fixedly connected to the first mesh frame 31, and the second damping component 42 is fixedly connected to the second mesh frame 41, the first noise reduction and vibration damping ring 3 and the second noise reduction and vibration damping ring 4 rotate as a whole. In this case, the first damping component 32, the second damping component 42 and the clearance compensation ring 12 need to be made of smooth TPU material so that the surface is smooth and can also play a damping role.

[0028] Thermoplastic polyurethane (TPU) is a high-quality material that simultaneously satisfies the requirements of smoothness, wear resistance, and shock absorption. TPU material can achieve high transparency and a smooth surface through injection molding.

[0029] TPU has more than twice the abrasion resistance of natural rubber and can maintain a low abrasion rate in both dry and wet environments, making it especially suitable for high-frequency friction scenarios.

[0030] TPU achieves a balance between elasticity and hardness through molecular structure design, allowing it to rebound quickly when impacted, reducing energy loss.

[0031] TPU has a lower density than traditional rubber, reducing equipment weight and improving mobility. It maintains stable performance within a temperature range of -40℃ to 80℃, making it suitable for extreme environments.

[0032] Dust covers are provided on both ends of the outer ring 1, and the dust covers are fastened between the end faces of the outer ring 1 and the end faces of the inner ring 5. The dust covers can prevent dust, impurities, etc. from entering the bearing, avoiding increased friction and wear caused by impurities, extending the service life of the bearing, and also helping to keep the inside of the bearing clean and reduce noise caused by foreign object interference. A sealing ring may also be provided inside the dust cover to prevent external liquids from entering the bearing sleeve of this utility model.

[0033] In this invention, both the first damping member 32 and the second damping member 42 can be damping balls.

[0034] The contact surfaces of the outer ring 1, the rolling retainer 2, the first noise reduction and vibration damping ring 3, the second noise reduction and vibration damping ring 4, and the inner ring 5 are all tightly fitted to maximize the tight integration effect of this utility model.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
