[0035] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0037] In the present application, unless otherwise stated, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves. Similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the present application.

[0038] As shown in Figures 1 to 5 The embodiments of the present application provide a bearing box, which comprises: at least two sealing portions, the at least two sealing portions comprising a first sealing portion and a second sealing portion, the first sealing portion and the second sealing portion jointly forming a first pollution-containing space 4 and a first pollution outlet 41, the first pollution outlet 41 being in communication with the first pollution-containing space 4; and a cleaning assembly 20, at least part of the cleaning assembly 20 being arranged in the first pollution-containing space 4, so as to spray cleaning liquid into the first pollution-containing space 4, so that the pollutants in the first pollution-containing space 4 are discharged through the first pollution outlet 41.

[0039] The bearing box of the present application adopts a cleaning assembly that replaces the traditional air backflush sealing method of continuously introducing compressed air by introducing cleaning liquid with a predetermined pressure. Compared with the continuous consumption of compressed air, this design greatly reduces energy consumption and operating costs. By providing the cleaning assembly 20 in the first dirt-containing space 4, the sealing structure of the present application can better adapt to different working environments, such as high temperature, high humidity, or environments with more dust. The use of cleaning liquid is not affected by pressure fluctuations, and it can effectively remove contaminants within a certain period of time, preventing them from entering the interior of the bearing box, thereby improving the reliability of the sealing structure. Under the jet pressure of the cleaning liquid, contaminants are effectively removed, avoiding the problem of incomplete cleaning due to insufficient air flow. The design of the first dirt outlet further simplifies the process of discharging contaminants, reducing maintenance time and labor costs.

[0040] By precisely spraying cleaning liquid into the first dirt-containing space, the sealing structure of the present application can effectively remove contaminants, preventing them from accumulating for a long time and causing damage to the internal parts of the bearing box, such as rust, wear, or oil deterioration. This not only improves the service life of the bearing box, but also reduces downtime caused by internal part failures, thereby enhancing the reliability of the entire system. The use of cleaning liquid can also avoid the vibration and noise problems that may be caused by compressed air in the sealing structure, improving the reliability of the overall structure.

[0041] In addition, the detachable design of the cleaning assembly allows maintenance or replacement without damaging the overall seal, avoiding additional damage caused by maintenance and further reducing maintenance costs.

[0042] As shown in Figure 1 The cleaning assembly 20 and the inner wall surface of the first dirt-containing space 4 together form a fluid cavity 21 for introducing cleaning liquid with a predetermined pressure; the cleaning assembly 20 is provided with a jet port 22 in communication with the fluid cavity 21, so that the cleaning liquid in the fluid cavity 21 is sprayed into the first dirt-containing space 4 through the jet port 22.

[0043] Optionally, at least one of the first and second sealing portions is provided with a liquid inlet channel in communication with the fluid cavity 21; and / or the cleaning assembly 20 further includes a liquid supply pipeline, one end of the liquid supply pipeline being connected to the fluid cavity 21, and the other end of the liquid supply pipeline extending out of the first dirt-containing space 4.

[0044] Specifically, the bearing box includes a box body 5 and a shaft body 6, the shaft body 6 being arranged in the bearing inner cavity 18 of the box body 5 and spaced apart from the box body 5; wherein the first sealing portion includes a flange 1, the flange 1 being sleeved outside the shaft body 6 and fixed on one side of the box body 5; the second sealing portion includes a movable ring 3, the movable ring 3 being sleeved outside the shaft body 6 and located at the end of the flange 1 away from the box body 5 to form the first dirt-containing space 4 with the flange 1.

[0045] In the above embodiment, the dynamic ring 3 keeps relative movement with the flange 1 when the shaft body 6 rotates, thereby preventing the external contaminants from directly entering the bearing box inner cavity. The cleaning assembly 20 is arranged in the first contaminant-containing space 4 and comprises the water guide component 2. The water guide component 2 is arranged around the shaft body 6 and forms the fluid cavity 21 with the groove part 11 on the flange 1. The fluid cavity 21 is provided with cleaning liquid under pressure through an external fluid supply system. The water guide component 2 is provided with a plurality of spray openings 22 in communication with the fluid cavity 21.

[0046] As shown in Figure 1 , the spray openings 22 are designed as strip-shaped holes and are inclined to the shaft body axis to ensure that the cleaning liquid can be uniformly and powerfully sprayed into the first contaminant-containing space 4 to remove the contaminants accumulated between the dynamic ring 3 and the flange 1. The first contaminant discharge port 41 is in communication with the first contaminant-containing space 4 and is used to discharge all the contaminants washed down by the cleaning liquid after cleaning, thereby ensuring the cleanliness of the bearing box interior and preventing the contaminants from re-entering the bearing inner cavity.

[0047] Specifically, the cleaning assembly 20 comprises the water guide component 2 which is detachably mounted on the flange 1 and encloses the fluid cavity 21 with the flange 1, and the spray openings 22 are arranged on the water guide component 2. This design enables the cleaning assembly 20 to be conveniently detached for cleaning or replacement after a period of use, thereby greatly reducing the maintenance cost and time. This design is particularly suitable for industrial environments that require frequent cleaning, such as food processing and pharmaceutical manufacturing, to ensure the hygiene and safety of the equipment and to reduce the performance degradation of the equipment caused by component aging or contamination, thereby prolonging the service life of the equipment.

[0048] In the above embodiment, the connection between the water guide component 2 and the flange 1 adopts threaded connection, buckle connection, magnetic attraction connection or special fixing parts, etc. These connection modes not only ensure the stability of the water guide component in a high-speed rotating and vibrating environment, but also enable the water guide component 2 to be quickly and conveniently detached when maintenance or replacement is required. To ensure the sealing of the fluid cavity 21, the contact surface of the water guide component 2 and the flange 1 is provided with a sealing ring or a sealing gasket. When the water guide component 2 is installed, the sealing ring is tightly fitted in the gap between the flange 1 and the water guide component 2 through compression deformation, thereby effectively preventing leakage of the cleaning liquid.

[0049] In the present embodiment, as shown in Figures 1 to 3As shown, the water guide component 2 includes a main body part 23 and a connecting part 24. The main body part 23 is arranged around the shaft body and is in close contact with the groove bottom wall 12 of the flange 1 to form the fluid cavity 21. The connecting part 24 extends along the axial direction of the shaft body and is connected with the groove side wall 13 of the flange 1 to fix the water guide component 2. The main body part 23 is provided with a fluid groove 25, and the groove opening of the fluid groove 25 is in opposite connection with the groove bottom wall 12 of the flange 1 to cooperatively form the fluid cavity 21. The design of the fluid groove 25 enables the cleaning liquid to be stably stored in the fluid cavity 21, ensuring sufficient spraying pressure and spraying effect.

[0050] As shown in Figures 1 to 4 , there is also a second sealing gap 14 between the flange 1 and the shaft body 6 for preventing the cleaning liquid from accidentally entering the bearing box. The flange 1 is provided with a containing cavity 15 in communication with the second sealing gap 14, and a drain port 16 for timely draining the cleaning liquid that may enter the second sealing gap 14, avoiding adverse effects on the inside of the bearing box.

[0051] In the above embodiment, as shown in Figure 1 and Figure 5 , a first sealing gap 7 is also provided between the flange 1 and the dynamic ring 3, which is located on the side of the dynamic ring 3 away from the shaft body 6. The existence of the first sealing gap 7 can effectively block external pollutants such as dust, moisture, and oil stains from directly entering the inner cavity of the bearing box, thereby protecting the bearing and other internal components from contamination and prolonging their service life. The first sealing gap 7 helps to retain the lubricant inside the bearing box, preventing it from leaking, ensuring that the bearing operates under good lubrication conditions, reducing wear and heat generation, and maintaining the optimal performance state of the bearing. Under the conditions of long-term operation or thermal expansion and contraction of the bearing box, the first sealing gap 7 can adapt to certain size changes, reducing direct friction between elements and avoiding sealing failure due to excessive wear. Specifically, the water guide component 2 is in a ring or arc shape, and is arranged around the shaft body 6 of the bearing box. The water guide component 2 is designed in a ring or arc shape, which matches the shape of the shaft body 6 of the bearing box, can tightly fit the outer surface of the shaft body 6, and has good stability in the axial and radial directions, and is not easy to displace or deform.

[0052] The annular or arc-shaped design of the water guide component 2 allows the cleaning liquid in the fluid cavity 21 to be uniformly distributed, ensuring that the fluid sprayed from the spray port 22 can cover the entire surface of the first pollution-containing space 4. This uniform distribution is particularly important for large equipment bearing boxes, as the first pollution-containing space 4 of a large bearing box has a large area, and it is difficult to achieve effective cleaning using traditional linear or point-like spraying methods. This structural design ensures that the cleaning liquid is uniformly sprayed throughout the first pollution-containing space 4, improving cleaning efficiency and being suitable for large equipment bearing boxes such as large fans, heavy machinery, etc., ensuring long-term stable operation of the equipment. At the same time, the annular or arc-shaped structure design also adapts to the shape of the shaft of different equipment, improving the universality and applicability of the cleaning assembly.

[0053] Specifically, the water guide component 2 includes a main body part 23 and a connecting part 24, and the flange 1 is provided with a groove part 11 for forming the first pollution-containing space 4, the groove part 11 includes a groove bottom wall 12 and a groove side wall 13 connected to each other, the groove bottom wall 12 is perpendicular to the axis of the shaft 6, the main body part 23 is in contact with the groove bottom wall 12 to enclose the fluid cavity 21, and the connecting part 24 is connected with the groove side wall 13. The main body part 23 of the water guide component 2 is annular or arc-shaped, closely fits the groove bottom wall 12 of the flange 1, and forms a closed fluid cavity 21 with the groove bottom wall 12. The main body part 23 is made of high-strength material to withstand the impact of high-pressure cleaning liquid, and a fluid groove 25 is provided inside to guide the flow of cleaning liquid and ensure uniform spraying.

[0054] Specifically, the connecting part 24 of the water guide component 2 cooperates with the groove side wall 13 of the flange 1, and is detachably connected through threads, buckles or other fixing devices. This design ensures the stable installation of the water guide component 2 inside the bearing box, and facilitates the maintenance and replacement of the cleaning assembly 20, reducing the downtime of the equipment due to maintenance. The groove part 11 on the flange 1 is composed of the groove bottom wall 12 and the groove side wall 13 to ensure the formation and sealing of the fluid cavity 21. Preferably, the groove bottom wall 12 is perpendicular to the axis of the shaft 6. The groove side wall 13 is an inclined or curved surface that cooperates with the connecting part 24, not only enhancing the stability of the connection, but also optimizing the internal structure of the fluid cavity 21 and improving the utilization efficiency of the cleaning liquid. This structural design not only improves the installation stability of the cleaning assembly 20, but also optimizes the formation of the fluid cavity 21, making it suitable for bearing boxes of various sizes and shapes, ensuring efficient use of cleaning liquid and reducing resource waste. At the same time, the stability and efficient use design also improves the continuity and effectiveness of the cleaning operation, further reducing the maintenance frequency and cost of the equipment.

[0055] As Figure 2As shown, specifically, the main body 23 is provided with a fluid groove 25, and the groove opening of the fluid groove 25 is in abutment with the groove bottom wall 12 to enclose the fluid cavity 21. The main body 23 is designed with the fluid groove 25, and the groove opening of the fluid groove 25 is in abutment with the groove bottom wall 12 of the flange 1 to form a closed fluid cavity 21. The shape and size of the fluid groove 25 are accurately calculated and optimized to ensure that the cleaning liquid flows smoothly into the fluid cavity 21, reduce turbulence and fluid loss, and improve the injection pressure and speed of the fluid. The inlet of the fluid groove 25 is designed to be gradual or diffused, which can guide the cleaning liquid to enter the fluid cavity 21 with small impact force and low turbulence. This design avoids the violent impact of the fluid when it enters, reduces the energy loss of the fluid when it enters the fluid cavity 21, and improves the utilization efficiency of the cleaning liquid.

[0056] As can be seen, the design of the fluid groove 25 enables the cleaning liquid to enter the fluid cavity 21 smoothly, avoids turbulence when the fluid enters, improves the injection effect of the cleaning liquid, and is suitable for precision equipment with high requirements for cleaning liquid injection, such as precision machine tools, aerospace equipment, etc., to ensure efficient operation of the equipment. At the same time, by optimizing the design of the fluid groove, the injection precision and coverage area of the cleaning liquid are improved, the cleaning effect is enhanced, and the risk of performance degradation of the equipment caused by pollutants is reduced.

[0057] As shown in Figure 3 and Figure 5 , the main body 23 and the connecting part 24 are arranged around the shaft body 6, one end of the connecting part 24 is connected with one end of the main body 23, and the other end of the connecting part 24 is arranged opposite to the dynamic ring 3 to form a pollution blocking gap 17. The main body 23 is designed to be annular or arc-shaped, and its inner diameter matches the outer diameter of the shaft body 6. By tightly fitting the outer surface of the shaft body 6, an effective sealing ring is formed. This design can reduce the risk of leakage of cleaning liquid during high-speed rotation, maintain the stability of the pressure in the fluid cavity 21, and improve the cleaning effect. One end of the connecting part 24 is connected with one end of the main body 23, and the other end is arranged opposite to the dynamic ring 3 to form a pollution blocking gap 17. Among them, the installation of the connecting part 24 adopts a detachable connection mode such as thread, buckle or magnetic attraction, which ensures the stability and maintainability of the cleaning assembly 20.

[0058] Specifically, the connecting portion 24 extends along the axial direction of the shaft body 6, and the end face of the connecting portion 24 opposite to the dynamic ring 3 is an inclined end face inclined to the axis of the shaft body 6. The inner wall face of the dynamic ring 3 facing the cleaning assembly is parallel to the inclined end face and is arranged in a spaced manner to form a small dirt blocking gap 17. The dirt blocking gap 17 can block the invasion of pollutants to a certain extent, reduce the pollution degree in the first dirt holding space 4, reduce the cleaning frequency of the cleaning assembly, and ensure the cleanliness of the bearing inner cavity 18. The connecting portion 24 is designed to be parallel to the central axis of the shaft body 6, which is to ensure that the connecting portion 24 can maintain a stable position when the shaft body 6 rotates, avoiding affecting the sealing effect due to deviation or vibration. The parallel arrangement of the inclined end face and the inner wall face of the dynamic ring 3 facing the cleaning assembly ensures that the connecting portion 24 and the dynamic ring 3 form a uniform dirt blocking gap 17.

[0059] Specifically, the fluid cavity 21 is annular and is arranged around the shaft body 6 of the bearing box; the injection ports 22 are multiple and are arranged in a spaced manner, and each injection port 22 is arranged towards the dynamic ring 3. The annular fluid cavity 21 and the multiple injection ports 22 can make the cleaning liquid form a fan-shaped flushing surface, which can flush away the pollutants entering the first dirt holding space 4, improve the cleaning effect, and be suitable for equipment with high requirements for the cleanliness of the surface of the dynamic ring 3, such as generators, motors, etc., to ensure the efficient operation of the equipment. At the same time, uniform injection also avoids the influence caused by local insufficient cleaning or excessive cleaning, improves the overall performance and operation efficiency of the equipment.

[0060] Specifically, the injection port 22 is a strip-shaped hole, one end of the strip-shaped hole is in communication with the fluid cavity 21, the other end of the strip-shaped hole is arranged towards the dynamic ring 3, and the hole center line of the strip-shaped hole is inclined to the axis of the shaft body 6. This design enables the cleaning liquid to be sprayed onto the dynamic ring 3 at a certain angle, thereby enhancing the impact force of the cleaning liquid. It is suitable for equipment with special requirements for cleaning effect, such as high-precision instruments and high-load equipment, to ensure the long-term stable operation of the equipment. At the same time, the inclined hole center line design also optimizes the injection path of the cleaning liquid, improves the efficiency and coverage area of the injection, and reduces the amount of cleaning liquid, which has significant economic and environmental benefits.

[0061] As shown in Figure 1 The inner wall face of the dynamic ring 3 facing the cleaning assembly 20 is provided with a conical surface for enclosing the dirt holding space, i.e., the first dirt holding space 4. In the radial direction of the shaft body 6, the conical surface gradually moves away from the box body 5 of the bearing box, so that the pollutants in the first dirt holding space 4 can be more easily thrown out from the first dirt outlet 41 under the action of centrifugal force, thereby improving the dirt removal effect of the bearing box of the present application.

[0062] Specifically, the second sealing gap 14 is formed between the flange 1 and the shaft body 6, the flange 1 and the shaft body 6 are provided with a containing cavity 15 communicating with the second sealing gap 14, and the flange 1 is provided with a drainage opening 16 communicating with the containing cavity 15. The design of the second sealing gap 14 and the drainage opening 16 can ensure that the contaminants after cleaning can be smoothly discharged, avoiding the secondary accumulation of contaminants, and is suitable for equipment that needs to be cleaned regularly, such as sewage treatment equipment, chemical reaction kettles, etc., ensuring the cleanliness and operation efficiency of the equipment, simplifying the cleaning operation, improving the maintenance convenience and safety of the equipment, reducing the working intensity of the maintenance personnel, and improving the work efficiency.

[0063] Preferably, the ratio between the outer diameter and the inner diameter of the first contaminant-containing space 4 is greater than or equal to 1.6.

[0064] In further embodiments of the present application, a second contaminant-containing space is formed between the flange 1 and the shaft body 6, and a second blowdown opening communicating with the second contaminant-containing space, the second contaminant-containing space is located on the side of the first contaminant-containing space 4 close to the bearing inner cavity 18, and the bearing box further comprises a blowing assembly, at least part of the blowing assembly is arranged in the second contaminant-containing space to blow air into the second contaminant-containing space, so that the contaminants in the second contaminant-containing space are discharged through the second blowdown opening.

[0065] Specifically, the flange 1 is provided with an annular groove for forming the second contaminant-containing space, the second contaminant-containing space is located between the first contaminant-containing space 4 and the containing cavity 15, and the second contaminant-containing space also communicates with the second sealing gap 14, and the blowing assembly is used to blow air to the contaminants in the second contaminant-containing space and the cleaning liquid entering the second contaminant-containing space from the second sealing gap 14, etc., so as to discharge them outside the second contaminant-containing space, further ensuring the cleanliness of the bearing inner cavity 18.

[0066] The present application also provides a wire cutting device comprising a main roller and a bearing, and the bearing box is the above-mentioned bearing box. The conventional wire cutting device bearing box needs to be frequently replaced with sealing materials or cleaned and maintained due to poor sealing performance, which not only increases the maintenance cost, but also may affect the production progress due to maintenance downtime.
