Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and in particular to a bearing housing that allows visualization of its internal structure. Background Technology

[0002] Bearing housings are the core load-bearing and rotating components of belt conveyors, and their selection and application directly determine the equipment's operational reliability, maintenance costs, and lifespan. However, conventional bearing housings lack inspection holes on their outer end covers. To observe the internal workings of the bearing housing, the belt conveyor must be stopped and the rollers disassembled, a process that is extremely time-consuming, labor-intensive, and disruptive to production.

[0003] Furthermore, the bearing housing is filled with grease to assist the rotation of the bearing and roller. When an observation window is set at the end of the bearing housing, the grease will not have a significant impact on the clarity of the observation window in the early stage. However, as the bearing housing is used continuously, the base oil inside the grease will precipitate from the thickener skeleton under the action of centrifugal force and heat, and splash onto the observation window, thus causing the field of view of the observation window to become blurred.

[0004] To address these issues, this invention proposes a bearing housing that allows visualization of the internal structure. Utility Model Content

[0005] The purpose of this invention is to provide a bearing housing that allows visualization of its internal structure, thereby addressing the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing housing with visible internal conditions, comprising a bearing housing body, wherein a through hole is formed inside the bearing housing body, and the two ends along the axial direction of the through hole are a closed end and an open end, respectively. A fixing ring coaxially arranged with the through hole is provided on one side of the closed end, and a transparent plate is provided inside the fixing ring. The transparent plate is located between the fixing ring and the bearing housing body, and a first sealing element and a second sealing element are respectively provided between the transparent plate, the fixing ring, and the bearing housing body. The closed end is internally fixedly connected with multiple circumferentially distributed snap-fit ​​components. The snap-fit ​​components are equipped with the same protective net. The protective net and the bearing seat body are equipped with mutually matched rotating components, which can drive the protective net to rotate.

[0007] Preferably, both the first and second sealing elements are annular sealing rings, the fixing ring has a first sealing groove that matches the first sealing element, and the bearing seat body has a second sealing groove that matches the second sealing element.

[0008] Preferably, the inner diameters of the first and second seals are the same, and the outer diameter of the second seal is greater than the outer diameter of the first seal and the diameter of the transparent plate.

[0009] Preferably, the snap-fit ​​component includes a snap-fit ​​ring fixedly connected to the bearing housing body, with a gap formed between the snap-fit ​​ring and the bearing housing body, and the protective mesh located within the gap.

[0010] Preferably, the bearing housing body includes a housing and a bearing inside the housing, the rotating component includes multiple fixing plates fixedly connected to the inner ring sidewall of the bearing, each of the multiple fixing plates is fixedly connected to a baffle, and the protective net is fixedly connected to multiple connecting rods that match the baffles.

[0011] Preferably, a sunshade is provided on one side of the fixing ring.

[0012] Preferably, a cleaning component matching the transparent panel is provided on one side of the protective net, and the cleaning component can clean the transparent panel when the protective net rotates.

[0013] Preferably, the cleaning component includes a fixed cylinder coaxially fixed with the protective net, a connecting shaft slidably connected inside the fixed cylinder, an elastic element provided between the connecting shaft and the fixed cylinder, and a scraper fixedly connected to the end of the connecting shaft away from the protective net, the scraper contacting the transparent plate.

[0014] Preferably, a first permanent magnet is provided at the axis of the sunshade, and a second permanent magnet is provided on the connecting shaft and the scraper, wherein the polarities of the opposite surfaces of the first and second permanent magnets are the same.

[0015] Preferably, the protective net has an annular protrusion on the side near the inner wall of the bearing housing body.

[0016] The beneficial effects of this utility model are: 1. This utility model, through the design of a transparent plate, snap-fit ​​components, and rotating components, allows maintenance personnel to directly visually inspect the working condition and grease status inside the bearing housing without stopping the machine to disassemble the roller. This enables quick and convenient non-stop inspection, significantly improving maintenance efficiency and reducing production interruption losses. Furthermore, the protective net can initially block grease splashes when static, and when rotating with the bearing, it can more effectively dissipate and block the precipitated base oil and impurities, greatly reducing the adhesion and accumulation of oil stains on the inside of the transparent plate. This maintains the clarity and usability of the transparent plate's field of vision during long-term operation.

[0017] 2. Through the design of the cleaning components, first permanent magnet, second permanent magnet, and protective net, the protective net, while rotating to block oil stains, directly drives the scraper to continuously and gently scrape and clean the surface of the transparent plate. This more proactively and effectively removes existing or forming oil films, significantly improving the self-cleaning ability and visibility of the observation window during long-term operation. Furthermore, when the sunshade is closed, the magnetic repulsion force drives the scraper to overcome the elastic force of the elastic element and move backward, disengaging it from the transparent plate and avoiding unnecessary idle wear, thus extending the service life of the scraper and the transparent plate. When the sunshade is opened to observe the internal condition of the bearing housing body, the magnetic repulsion force disappears, and the scraper automatically resets under the action of the elastic element and resumes its cleaning function, achieving the convenience and efficiency of cleaning while observing.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] In actual production, since there is no observation hole on the outer end cover of the conventional bearing housing, it is necessary to stop the belt conveyor and remove the roller to observe the working condition inside the bearing housing. This process is extremely time-consuming, labor-intensive, and delays production.

[0029] Furthermore, the bearing housing is filled with grease to assist the rotation of the bearing and roller. When an observation window is set at the end of the bearing housing, the grease will not have a significant impact on the clarity of the observation window in the early stage. However, as the bearing housing is used continuously, the base oil inside the grease will precipitate from the thickener skeleton under the action of centrifugal force and heat, and splash onto the observation window, thus causing the field of view of the observation window to become blurred.

[0030] This embodiment is proposed to solve the above problems.

[0031] Please see Figures 1 to 8 As shown, an embodiment of the present invention provides a bearing housing that allows visualization of its internal structure. The bearing housing body 1 has a through hole formed inside. Two ends along the axis of the through hole are a closed end 11 and an open end 12, respectively. A fixing ring 2, coaxially arranged with the through hole, is provided on one side of the closed end 11. A transparent plate 3 is disposed inside the fixing ring 2, located between the fixing ring 2 and the bearing housing body 1. In this embodiment, the transparent plate 3 can be made of acrylic or tempered glass. An oleophobic coating can be applied to the side of the transparent plate 3 closest to the interior of the bearing housing body 1. A first sealing element 4 and a second sealing element 41 are respectively provided between the transparent plate 3, the fixing ring 2, and the bearing housing body 1.

[0032] The closed end 11 is internally fixedly connected with multiple circumferentially distributed snap-fit ​​parts 5. The snap-fit ​​parts 5 are internally provided with the same protective net 6. The protective net 6 and the bearing seat body 1 are provided with mutually matched rotating parts 7. The rotating parts 7 can drive the protective net 6 to rotate.

[0033] Both the first sealing element 4 and the second sealing element 41 are annular sealing rings. The fixing ring 2 has a first sealing groove that matches the first sealing element 4, and the bearing housing body 1 has a second sealing groove that matches the second sealing element 41.

[0034] The inner diameters of the first sealing element 4 and the second sealing element 41 are the same, and the outer diameter of the second sealing element 41 is larger than the outer diameter of the first sealing element 4. This arrangement is to ensure that the transparent plate 3 is covered by the second sealing element 41, thereby protecting the edges and corners of the transparent plate 3 while ensuring its airtightness.

[0035] The snap-fit ​​component 5 includes a snap-fit ​​ring 51 fixedly connected to the bearing housing body 1, with a gap 52 formed between the snap-fit ​​ring 51 and the bearing housing body 1, and the protective net 6 located within the gap 52.

[0036] The bearing housing body 1 includes a housing and a bearing inside the housing. The rotating component 7 includes multiple fixing plates 71 fixedly connected to the inner ring sidewall of the bearing. Each fixing plate 71 is fixedly connected to a baffle 72. The protective net 6 is fixedly connected to multiple connecting rods 73 that match the baffles 72.

[0037] To prevent the transparent plate 3, the first seal 4, and the second seal 41 from aging rapidly under sunlight, a sunshade 8 is provided on one side of the fixing ring 2. Under normal conditions, the sunshade 8 is fixed to the fixing ring 2 by magnetic attraction or hinge to avoid direct sunlight. When it is necessary to check the condition inside the bearing seat through the observation window, simply open the sunshade 8.

[0038] In order to reduce the friction when the protective net 6 rotates and reduce the wear of the protective net 6, an annular protrusion 61 is provided on the side of the protective net 6 near the inner wall of the bearing seat body 1.

[0039] In use, first install the protective net 6 and transparent plate 3 on the bearing seat. During installation, first place the protective net 6 into the gap 52 between the multiple snap rings 51 and the bearing seat body 1, and make the connecting rod 73 contact the baffle 72 on the inner ring of the bearing. Then, insert the first sealing member 4 and the second sealing member 41 into the first sealing groove and the second sealing groove respectively. Then, make the transparent plate 3 contact the second sealing member 41 and install the fixing ring 2. The first sealing member 4 and the second sealing member 41 are in direct contact with the transparent plate 3 and are fixed to it.

[0040] The idler roller or roller shaft of the belt conveyor is directly connected to the bearing housing body 1 through the open end 12. During the operation of the bearing housing body 1, the inner ring of the bearing rotates synchronously with the idler roller or roller shaft. At this time, the protective net 6 will rotate under the drive of the fixed plate 71, the baffle 72 and the connecting rod 73. When the protective net 6 is stationary, it can simply shield the grease and prevent the base oil in it from splashing onto the transparent plate 3. When the protective net 6 is rotating, it will not affect the field of vision of the observation window too much, and will further improve the shielding effect of the grease.

[0041] It should be noted that when maintenance personnel inspect the inside of the bearing housing body 1, the operating speed of the belt conveyor can be appropriately reduced.

[0042] In summary, the transparent plate 3, snap-fit ​​component 5, and rotating component 7 allow maintenance personnel to visually inspect the working condition and grease status inside the bearing housing without stopping the machine to disassemble the roller. This enables quick and convenient non-stop inspection, significantly improving maintenance efficiency and reducing production interruption losses. Furthermore, the protective net 6 can initially block grease splashes when static, and when rotating with the bearing, it can more effectively remove and block the precipitated base oil and impurities, greatly reducing the adhesion and accumulation of oil on the inside of the transparent plate 3. This ensures the clarity and usability of the transparent plate 3's field of vision during long-term operation.

[0043] In addition, the openable sunshade 8 design prevents the transparent panel 3 and sealing material from aging faster due to direct sunlight, thus extending the service life of the transparent panel 3. Example 2

[0044] In actual use, it was found that it is difficult to completely prevent the oil film from appearing on the transparent plate 3 by simply rotating the protective net 6. Furthermore, once the field of vision of the transparent plate 3 becomes blurred, it is difficult to clean it. Therefore, this embodiment makes further improvements based on the above embodiment.

[0045] Please see Figures 6 to 8 As shown, a cleaning component 9 matching the transparent plate 3 is provided on one side of the protective net 6. When the protective net 6 rotates, it can drive the cleaning component 9 to clean the transparent plate 3.

[0046] The cleaning component 9 includes a fixed cylinder 91 that is coaxially fixed with the protective net 6. A connecting shaft 92 is slidably connected inside the fixed cylinder 91. An elastic element is provided between the connecting shaft 92 and the fixed cylinder 91. A scraper 93 is fixedly connected to the end of the connecting shaft 92 away from the protective net 6. The scraper 93 is in contact with the transparent plate 3.

[0047] In this embodiment, a slot is provided on the connecting shaft 92, and a block matching the slot is provided inside the fixed cylinder 91, so that the connecting shaft 92 can only slide axially. Furthermore, the elastic element is a compression spring, and the two ends of the compression spring are fixedly connected to the connecting shaft 92 and the fixed cylinder 91, respectively.

[0048] A first permanent magnet 81 is provided at the axis of the sunshade 8, and a second permanent magnet 921 is provided on the connecting shaft 92 and the scraper 93. The polarities of the opposite surfaces of the first permanent magnet 81 and the second permanent magnet 921 are the same.

[0049] Based on the above embodiments, a cleaning component 9 that can rotate with the protective net 6 is coaxially arranged on the protective net 6. When the protective net 6 rotates, the fixed cylinder 91 drives the connecting shaft 92 and the scraper 93 to rotate. At this time, the scraper 93 can clean the surface of the transparent plate 3, and the elastic component can ensure that there is appropriate pressure between the scraper 93 and the transparent plate 3.

[0050] It should be noted that in this embodiment, the scraper 93 uses brush bristles to contact the transparent plate 3 to avoid hard contact between the two. When the transparent plate 3 is heavily contaminated, a certain amount of cleaning fluid can be injected into the interior of the bearing housing body 1 through the grease injection port to assist in cleaning.

[0051] Furthermore, in order to improve the service life of the scraper 93 and reduce the wear of the transparent plate 3, when the sunshade 8 is closed, the repulsive force between the first permanent magnet 81 and the second permanent magnet 921 will cause the connecting shaft 92 to drive the scraper 93 to move to one side of the protective net 6, so that the scraper 93 is out of contact with the transparent plate 3. When the maintenance personnel open the sunshade 8 to observe the inside of the bearing seat body 1, the repulsive force between the first permanent magnet 81 and the second permanent magnet 921 disappears, and the scraper 93 and the connecting shaft 92 are reset under the action of the elastic element, thereby cleaning the transparent plate 3.

[0052] In summary, through the arrangement of the cleaning component 9, the first permanent magnet 81, the second permanent magnet 921, and the protective net 6, the protective net 6, while rotating to block oil stains, can directly drive the scraper 93 to continuously and gently scrape and clean the surface of the transparent plate 3. This allows for more proactive and effective removal of existing or forming oil films, significantly improving the self-cleaning ability and visibility of the observation window during long-term operation. Furthermore, when the sunshade 8 is closed, the magnetic repulsion force drives the scraper 93 to overcome the elastic force of the elastic element and move backward, disengaging it from the transparent plate 3. This avoids unnecessary idle wear and extends the service life of the scraper 93 and the transparent plate 3. When the sunshade 8 is opened to observe the internal condition of the bearing housing body 1, the magnetic repulsion force disappears, and the scraper 93 automatically resets under the action of the elastic element and resumes its cleaning function, achieving the convenience and efficiency of cleaning while observing.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
