Description

Technical Field

[0001] This invention relates to the field of bearing technology, specifically to a bearing seal and a bearing. Background Technology

[0002] Bearings play a crucial role in industrial robots and high-speed trains, primarily reducing friction and wear between moving parts. However, in practical applications, existing bearings and seals face numerous challenges during installation and use. Installation mainly relies on manual pressing to achieve an interference fit. Because manual force is difficult to control precisely, uneven stress on the seal can easily occur, leading to gaps between the seal and the bearing, thus compromising the integrity of the sealing structure.

[0003] In high-speed trains, the inner ring of the axle box bearing is tightly fitted to the axle and rotates circumferentially with the wheelset. The outer ring is installed inside the axle box, bearing the weight of the vehicle and remaining relatively stationary. Similarly, in industrial robots, the inner ring of some joints is often designed to connect to the joint shaft and rotate with it, while the outer ring is fixed to the robot's body or arm structure. Therefore, the inner ring directly bears the radial and axial loads of the rotating components, causing the bearing to be constantly at high temperatures. This alters the properties of the sealing ring material, causing it to deform and warp. However, existing bearing and sealing ring structures and installation methods lack flexibility and do not have automatic compensation mechanisms, making it impossible to adjust for sealing ring deformation caused by high temperatures in real time. Deformed sealing rings fail, allowing impurities to enter the bearing, accelerating the wear of critical components such as balls and raceways, and reducing bearing precision. At the same time, sealing failure leads to lubricant leakage, which in turn causes insufficient lubrication. Frictional heat further deteriorates the bearing's working environment, creating a vicious cycle.

[0004] Furthermore, while the sealed bearing design effectively prevents lubricant leakage and impurity intrusion, it presents challenges for lubricant replenishment. Because it's difficult to add new lubricant, the existing lubricant inside the bearing is continuously consumed over long-term use without timely replenishment, significantly increasing friction between components such as the rolling elements, inner ring, outer ring, and cage, thus exacerbating wear.

[0005] Furthermore, when the bearing rotates at high speed, the lubricating oil will move radially towards the bearing edge and accumulate at the bottom of the gasket. This will not only put additional pressure on the gasket, accelerating its deformation, aging and wear, and reducing its sealing performance, but will also lead to insufficient lubricating oil in critical parts of the bearing. Due to poor lubrication, the contact surfaces of the balls and raceways, the inner ring of the bearing and the journal will experience increased friction and aggravated wear. In severe cases, it may even cause bearing overheating, seizure and other failures, affecting the normal operation of the equipment.

[0006] Therefore, a bearing seal ring and a bearing are proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a bearing seal and a bearing to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a bearing sealing ring, comprising two thermal compensation units, which are used for sealing compensation of the bearing. The bearing consists of a bearing steel inner ring, a bearing steel outer ring, a high-temperature bearing steel cage, and multiple high-temperature bearing steel balls. The bearing steel inner ring is located inside the bearing steel outer ring, and the multiple high-temperature bearing steel balls are located between the bearing steel inner ring and the bearing steel outer ring, separated by two high-temperature bearing steel cages. The thermal compensation unit includes a high-temperature bearing steel bearing ring, which is fixedly connected to the inner ring surface of the bearing steel outer ring. A high-temperature bearing steel outer ring is fixedly connected to the outer ring surface of the bearing steel inner ring at a corresponding position to the high-temperature bearing steel bearing ring. A groove is provided on the high-temperature bearing steel outer ring, and a rubber sealing ring is provided on the high-temperature bearing steel bearing ring. Four support rods are inserted in a circular array in the groove.

[0009] Furthermore, a rubber stopper is fixedly connected to the bottom of each of the four support rods, a stainless steel pressure plate is fixedly connected to the top of each of the four support rods, and a metal spring is fixedly connected to each of the four support rods.

[0010] Furthermore, protrusions extend from the outer ring surface of the high-temperature bearing steel outer ring, and the rubber sealing ring is rotatably connected to the protrusions of the high-temperature bearing steel outer ring, with the slot being set in a convex shape.

[0011] Furthermore, multiple support grooves are arranged in a ring array on the high-temperature bearing steel bearing ring, and multiple support plates corresponding to the support grooves on the high-temperature bearing steel bearing ring extend from the outer ring surface of the rubber sealing ring.

[0012] Furthermore, the cross-section of the rubber stopper is set as a rhombus shape, wider at the top and narrower at the bottom.

[0013] Furthermore, the stainless steel pressure plate extends towards the high-temperature bearing steel bearing ring, and the lower surface of the end of the stainless steel pressure plate away from the high-temperature bearing steel outer ring is in contact with the upper surface of the high-temperature bearing steel bearing ring.

[0014] Furthermore, the two ends of the metal spring extend through both sides of the support rod and are located at the bottom of the stainless steel pressure plate.

[0015] A bearing includes two filling units, which are symmetrically arranged on the upper and lower sides of the inner and outer rings of the bearing steel. Each filling unit includes an upper hook plate, which is fixedly connected to the outer ring surface of the inner ring of the bearing steel. A lower hook plate is fixedly connected to the inner ring surface of the outer ring of the bearing steel. An oil filling groove is provided on the outer ring of the bearing steel, and a cap is threadedly connected to the top of the inner wall of the oil filling groove.

[0016] Furthermore, the upper and lower hook plates are staggered vertically, with the ends of the upper and lower hook plates that are close to each other being arc-shaped, and the ends of the upper and lower hook plates that are close to each other extending into the arc of the other, and the upper and lower hook plates do not fit together.

[0017] Furthermore, the bottom of the oil filling groove is inclined towards the top of the high-temperature bearing steel ball, and the top surface of the cap is flush with the top surface of the outer ring of the bearing steel.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] By having four stainless steel pressure plates work in tandem with the bearing and rotate on the sealing ring during actual bearing operation, providing downward pressure to the sealing ring in real time, the sealing ring can be smoothed out when it deforms and warps due to heat. This solves the problem of the lack of flexibility in the existing bearing and sealing ring structure and installation method, which makes it impossible to adjust the sealing ring deformation caused by high temperature in real time, thus ensuring the sealing function of the sealing ring.

[0020] By setting four user-operated stainless steel pressure plates on the sealing ring, rotating the stainless steel pressure plates during installation can evenly flatten the sealing ring. This solves the problem that when manually pressing the ring for installation, it is difficult to accurately control the force applied by human force, resulting in uneven force on the sealing ring, gaps formed in some areas where the ring does not fit tightly with the bearing, and damage to the integrity of the sealing structure. This ensures the sealing function of the sealing ring.

[0021] By isolating the high-temperature bearing steel balls from the seal ring, the lubricating oil is prevented from moving radially towards the bearing edge and accumulating at the bottom of the seal. This avoids the lubricating oil exerting additional pressure on the seal, reducing deformation, aging, and wear of the seal caused by additional pressure. This helps maintain the sealing performance of the seal, reduces the frequency of bearing replacement due to seal damage, and saves maintenance costs and time.

[0022] At the same time, it prevents lubricating oil from accumulating at the bearing edge, ensuring the amount of lubricating oil in critical parts of the bearing, avoiding increased friction and wear caused by poor lubrication, and reducing the possibility of bearing overheating, seizure and other failures.

[0023] The addition of a lubrication unit provides a direct way to add lubricating oil to the bearing, solving the problem of difficulty in replenishing new lubricating oil in sealed bearings. This allows for timely replenishment of lubricating oil, reduces friction and wear between bearing components, and extends the overall service life of the bearing. Reduced wear on internal bearing components enables the bearing to operate more stably. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0038] The embodiments provided by this invention:

[0039] Example 1:

[0040] Please see Figures 1 to 9 As shown, a bearing seal ring and a bearing include two thermal compensation units. The thermal compensation units are used to perform sealing compensation on the bearing. The bearing is divided into a bearing steel inner ring 11, a bearing steel outer ring 12, a high-temperature bearing steel cage 13, and a plurality of high-temperature bearing steel balls 14. The bearing steel inner ring 11 is located inside the bearing steel outer ring 12. The plurality of high-temperature bearing steel balls 14 are between the bearing steel inner ring 11 and the bearing steel outer ring 12 and are separated by two high-temperature bearing steel cages 13. The two high-temperature bearing steel cages 13 are symmetrically arranged and fixedly connected to each other by rivets.

[0041] It should be added that: In this case, the inner ring 11 of the bearing steel is connected to the rotating component, that is, during the operation of the bearing, the inner ring 11 of the bearing steel rotates, while the outer ring 12 of the bearing steel is connected to the stationary component, that is, during the operation of the bearing, the outer ring 12 of the bearing steel does not rotate.

[0042] Two thermal compensation units are symmetrically arranged on the upper and lower sides of the inner ring 11 and outer ring 12 of the bearing steel. The thermal compensation unit includes a high-temperature bearing steel bearing ring 22, which is fixedly connected to the inner ring surface of the outer ring 12 of the bearing steel. A high-temperature bearing steel outer ring 23 is fixedly connected to the outer ring surface of the inner ring 11 of the bearing steel at the corresponding position of the high-temperature bearing steel bearing ring 22. A slot 24 is provided on the high-temperature bearing steel outer ring 23. A rubber sealing ring 25 is provided on the high-temperature bearing steel bearing ring 22. Four support rods 26 are inserted in a ring array in the slot 24. A rubber plug 27 is fixedly connected to the bottom end of each of the four support rods 26. A stainless steel pressure plate 28 is fixedly connected to the top end of each of the four support rods 26. A metal spring 21 is fixedly connected to each of the four support rods 26.

[0043] Where: Reference Figure 5 , Figure 9 As shown, a protrusion extends from the outer ring surface of the high-temperature bearing steel outer ring 23, and the rubber sealing ring 25 is rotatably connected to the protrusion of the high-temperature bearing steel outer ring 23.

[0044] Where: Reference Figure 2 , Figures 5 to 9 As shown, the high-temperature bearing steel support ring 22 has multiple support grooves arranged in a ring array. The outer ring surface of the rubber sealing ring 25 extends multiple support plates corresponding to the support grooves on the high-temperature bearing steel support ring 22. Specifically, the support plates of the rubber sealing ring 25 fit into the support grooves of the high-temperature bearing steel support ring 22, and the support grooves of the high-temperature bearing steel support ring 22 do not penetrate the high-temperature bearing steel support ring 22.

[0045] It should be added that when the rubber sealing ring 25 is placed on the high-temperature bearing steel bearing ring 22 through the mounting plate and the mounting groove of the high-temperature bearing steel bearing ring 22, the rubber sealing ring 25 is flush with the top surface of the high-temperature bearing steel bearing ring 22. Since the high-temperature bearing steel bearing ring 22 will not rotate with the bearing, the rubber sealing ring 25 is in a static sealing state during the bearing operation.

[0046] Where: Reference Figure 5 , Figure 8 As shown, the slot 24 is convex in shape. Specifically, the top of the slot 24 connects to the external space, the top of the slot 24 is a narrow path, and the bottom of the slot 24 is a wide path. The support rod 26 is slidably connected to the narrow path of the slot 24. The cross-section of the rubber plug 27 is rhomboid, and the rhomboid cross-section of the rubber plug 27 is larger than the narrow path of the slot 24. Combined with the rubber properties of the rubber plug 27, the rubber plug 27 can be inserted into the width of the slot 24 from top to bottom through the narrow path of the slot 24 under the action of external force. Specifically, within the open path: when the rubber stopper 27 is within the narrow path of the slot 24, the two inclined sides of the rhomboid lower surface of the rubber stopper 27 abut against the narrow path of the slot 24, and the rubber stopper 27 undergoes elastic deformation. At this time, the two inclined sides of the rhomboid lower surface of the rubber stopper 27 guide the sliding and deformation of the rubber stopper 27. When the rubber stopper 27 is inserted into the wide path of the slot 24, the rubber stopper 27 elastically extends, and the two inclined sides of the rhomboid upper surface of the rubber stopper 27 abut against the narrow path of the slot 24, and refer to... Figure 8 As shown, the rhomboid shape of the rubber plug 27 is wider at the top and narrower at the bottom. Its function is as follows: when the two inclined sides of the upper surface of the rhomboid of the rubber plug 27 abut against the narrow path of the slot 24, the two inclined sides of the upper surface of the rhomboid of the rubber plug 27 can guide the sliding and deformation of the rubber plug 27. However, the external force required to pull the rubber plug 27 out of the slot 24 needs to be greater to prevent the rubber plug 27 from falling off inside the slot 24 due to vibration, shaking or other factors on the outer wall of the bearing during daily operation, thus ensuring the stability of the rubber plug 27 when it is inserted into the slot 24.

[0047] It should be added that when the rubber plug 27 is inserted into the spacious path of the slot 24, the rubber plug 27 and the slot 24 are interference-fitted. Specifically, the rotation of the bearing steel inner ring 11 can drive the support rod 26 to rotate synchronously, and the stainless steel pressure plate 28 fixed on the support rod 26 also rotates synchronously.

[0048] Where: Reference Figure 5As shown, the stainless steel pressure plate 28 extends towards the high-temperature bearing steel bearing ring 22. When the rubber sealing ring 25 is installed on the bearing, the lower surface of the stainless steel pressure plate 28 is in contact with the upper surface of the rubber sealing ring 25. The lower surface of the end of the stainless steel pressure plate 28 away from the high-temperature bearing steel outer ring 23 is in contact with the upper surface of the high-temperature bearing steel bearing ring 22. The function is to ensure that the stainless steel pressure plate 28 can contact the rubber sealing ring 25 in real time during the rotation process.

[0049] Where: Reference Figure 5 , Figure 8 As shown, the two ends of the metal spring 21 protrude from both sides of the support rod 26 and are located at the bottom of the stainless steel pressure plate 28. The metal spring 21 has a unique shape memory effect and good elasticity, such as... Figure 8 As shown, the original shape of the metal spring 21 is that its two ends are curled downwards, but when the rubber stopper 27 is inserted into the slot 24, the metal spring 21 is as follows: Figure 5 As shown, the two ends of the metal spring 21 abut against the stainless steel pressure plate 28 and the bearing steel inner ring 11. At this time, the metal spring 21 undergoes elastic deformation. The two ends of the metal spring 21 abut against the stainless steel pressure plate 28 and the bearing steel inner ring 11, which plays a role in limiting and supporting. However, the thrust provided by the metal spring 21 is insufficient to pull the rubber plug 27 out of the slot 24. At this time, the two inclined sides at the top of the rubber plug 27 play a role in restricting the metal spring 21 from pulling the rubber plug 27 out of the slot 24. Thus, under the combined action of the two inclined sides at the top of the rubber plug 27, the support rod 26 and the elastic deformation of the metal spring 21, the support rod 26 can be restricted in position by the bidirectional force of the rubber plug 27 and the metal spring 21 when the rubber plug 27 is inserted into the slot 24. That is, the position state of the support rod 26 driving the stainless steel pressure plate 28 to adhere to the top surface of the rubber sealing ring 25 is fixed, ensuring that the stainless steel pressure plate 28 can abut against and adhere to the rubber sealing ring 25 in real time during the rotation.

[0050] It should be noted that the bearings assembled above are suitable for the inner ring rotation bearings used in industrial robots and high-speed trains.

[0051] When installing the rubber sealing ring 25, the user places the end of the rubber sealing ring 25 closest to the high-temperature bearing steel outer ring 23 onto the protrusion of the high-temperature bearing steel outer ring 23. Then, the user inserts the rubber sealing ring 25 into the high-temperature bearing steel bearing ring 22, ensuring that the multiple mounting plates on the rubber sealing ring 25 align with the multiple mounting grooves on the high-temperature bearing steel bearing ring 22. After completion, the user inserts the rubber plug 27 into the slot 24. At this point, the thermal compensation unit... Figure 2 , Figure 4 , Figure 5 The state shown.

[0052] After the rubber sealing ring 25 is installed, the user keeps the stainless steel pressure plate 28 in contact with the rubber sealing ring 25 and rotates the inner ring 11 of the bearing steel to rotate the stainless steel pressure plate 28 one revolution on the rubber sealing ring 25. This allows for uniform pressure on the rubber sealing ring 25, making the connection between the rubber sealing ring 25, the outer ring 23 of the high-temperature bearing steel, and the bearing ring 22 of the high-temperature bearing steel more secure. At the same time, it enables simple and quick installation of the bearing seal ring.

[0053] When it is necessary to remove the rubber sealing ring 25, the user only needs to pull the stainless steel pressure plate 28 towards the top of the bearing steel inner ring 11. At this time, the stainless steel pressure plate 28 applies an upward pulling force to the support rod 26. It should be noted that the pulling force applied by the user is much greater than the pushing force of the metal spring 21 on the support rod 26. Then, under the guidance of the two inclined surfaces at the top of the rubber plug 27, the rubber plug 27 is pulled out from the groove 24. The user can then remove the rubber sealing ring 25 from the high-temperature bearing steel outer ring 23 and the high-temperature bearing steel bearing ring 22, which can achieve simple and quick bearing seal removal.

[0054] When the bearing is in use, the support rod 26, rubber plug 27, stainless steel pressure plate 28, and other structures are installed together with the bearing as part of the sealing ring. As can be seen from the function of the stainless steel pressure plate 28 mentioned above, as the bearing runs, the stainless steel pressure plate 28 rotates between the inner ring 11 and the outer ring 12 of the bearing steel. At the same time as the rotation, the bottom surface of the stainless steel pressure plate 28 is in constant contact with the rubber sealing ring 25. If the rubber sealing ring 25 is deformed or warped at this time, the rotation and contact of the stainless steel pressure plate 28 can apply downward pressure to the deformed or warped part of the rubber sealing ring 25, smoothing out the deformed or warped rubber sealing ring 25 and preventing the deformation or warping of the rubber sealing ring 25 from causing the sealing function to fail.

[0055] In summary, during the operation of the thermal compensation unit, by setting four user-driven stainless steel pressure plates 28 on the sealing ring, rotating the stainless steel pressure plates 28 during installation can evenly flatten the sealing ring, solving the problem that manual pressing installation is difficult to control precisely, resulting in uneven force on the sealing ring, poor local contact with the bearing, and gaps that damage the integrity of the sealing structure, thus ensuring the sealing function of the sealing ring.

[0056] Meanwhile, during actual operation of the bearing, four stainless steel pressure plates 28 work in tandem with the bearing and rotate on the sealing ring, providing downward pressure to the sealing ring in real time. This can smooth out the sealing ring when it deforms and warps due to heat, solving the problem that the existing bearing and sealing ring structure and installation method lacks flexibility and cannot adjust the sealing ring deformation caused by high temperature in real time, thus ensuring the sealing function of the sealing ring.

[0057] Example 2:

[0058] Reference Figures 1 to 4 As shown, two filling units are symmetrically arranged on the upper and lower sides of the bearing steel inner ring 11 and the bearing steel outer ring 12. The filling unit includes an upper hook plate 31, which is fixedly connected to the inner ring surface of the bearing steel outer ring 12. A lower hook plate 32 is fixedly connected to the inner ring surface of the bearing steel outer ring 12. An oil filling groove 33 is opened on the bearing steel outer ring 12, and a cap 34 is threadedly connected to the top of the inner wall of the oil filling groove 33.

[0059] Where: Reference Figure 4 As shown, the upper hook plate 31 and the lower hook plate 32 are staggered vertically. The ends of the upper hook plate 31 and the lower hook plate 32 that are close to each other are both set as arcs, and the ends of the upper hook plate 31 and the lower hook plate 32 that are close to each other extend into the arc of the other, and the upper hook plate 31 and the lower hook plate 32 do not fit together.

[0060] It should be noted that: (Refer to) Figure 4 As shown, the upper hook plate 31 and the lower hook plate 32 isolate the high-temperature bearing steel ball 14 from the sealing ring. At the same time, since the upper hook plate 31 and the lower hook plate 32 do not fit together, that is, when the bearing steel inner ring 11 drives the upper hook plate 31 to rotate and the bearing steel outer ring 12 drives the lower hook plate 32 to rotate, the isolation effect of the upper hook plate 31 and the lower hook plate 32 is still effective, but it will not affect the rotation of the bearing steel inner ring 11 and the bearing steel outer ring 12.

[0061] It should be noted that the upper hook plate 31 and the lower hook plate 32 are designed to isolate the high-temperature bearing steel balls 14 from the sealing ring, preventing the lubricating oil from moving radially towards the bearing edge and accumulating at the bottom of the sealing gasket. This avoids the lubricating oil exerting additional pressure on the sealing gasket, reduces deformation, aging, and wear of the sealing gasket caused by additional pressure, helps maintain the sealing performance of the sealing gasket, reduces the frequency of bearing replacement due to sealing gasket damage, and saves maintenance costs and time.

[0062] At the same time, it prevents lubricating oil from accumulating at the bearing edge, ensuring the amount of lubricating oil in critical parts of the bearing, avoiding increased friction and wear caused by poor lubrication, and reducing the possibility of bearing overheating, seizure and other failures.

[0063] Where: Reference Figure 4 As shown, the bottom end of the oil filling groove 33 slopes towards the top of the high-temperature bearing steel ball 14, serving to guide the lubricating oil to flow towards the high-temperature bearing steel ball 14. The top surface of the cover 34 is flush with the top surface of the bearing steel outer ring 12, serving to prevent the cover 34 from affecting the operation of the bearing steel outer ring 12. A cross groove is provided on the cover 34, serving to facilitate the user to remove the cover 34 with a screwdriver or similar tool.

[0064] When lubricating oil needs to be added, the user uses a Phillips screwdriver to rotate and remove the cap 34, and adds lubricating oil through the opening at the top of the oil filling groove 33. The lubricating oil enters the high-temperature bearing steel ball 14 under the guidance of the inclined surface of the oil filling groove 33.

[0065] In summary, the addition of the lubrication unit provides a direct way to add lubricating oil to the bearing, solving the problem of difficulty in replenishing new lubricating oil in sealed bearings. This allows for timely replenishment of lubricating oil, reduces friction and wear between bearing components, and extends the overall service life of the bearing. Reduced wear on internal bearing components also enables the bearing to operate more stably.
