Description

Technical Field

[0001] This invention belongs to the field of bearing technology, and specifically relates to a pedestal self-aligning roller bearing. Background Technology

[0002] Bearings are an important component in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] Self-aligning roller bearings consist of inner rings with two raceways and outer rings with spherical raceways, with drum-shaped rollers assembled between them. Self-aligning roller bearings have two rows of rollers and primarily bear radial loads, but can also withstand axial loads in either direction.

[0004] When existing self-aligning roller bearings are used in heavy machinery, if the internal rollers break, the staff can be informed of the situation in time through the monitoring equipment. However, after the staff shuts down the equipment, the shaft will not stop immediately, but will continue to rotate for a period of time before stopping. The rollers will push the fragments of the rollers along the slideway on the inner side of the outer ring of the bearing, causing scratches to the slideway.

[0005] Therefore, it is necessary to invent a mounted self-aligning roller bearing to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a pedestal self-aligning roller bearing to solve the issues raised in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a self-aligning roller bearing with a seat, comprising a support, an outer ring fixedly installed inside the support, an inner ring disposed inside the outer ring, a cage fixed outside the inner ring, and rollers equidistantly distributed on the cage; A collection component for collecting fragments generated by the broken rollers, preventing the fragments from scratching the inner track of the outer ring; The collection component includes: The annular shell is fixed to the outside of the retainer; The brackets are equidistantly arranged on the outer side of the annular shell; An electromagnet, installed inside the bracket, has magnetic properties to collect fragments when energized; A guide pad is provided on the outside of the electromagnet to ensure that when the fragments are attracted to the electromagnet, they can be removed from the inner slide of the outer ring. A drive assembly for energizing the electromagnet and moving it toward the outer ring when the roller breaks.

[0008] Furthermore, the driving component includes: A rectangular column is connected to the inner wall of the bracket, and the electromagnet is slidably mounted on the rectangular column; A first spring connects the rectangular column to the electromagnet; A magnetic plate is attached to the inner wall of the bracket; A controller is located inside the annular shell, and the controller can control the electromagnet; A vibration analyzer, located on the outside of the outer ring, can detect the breakage of the roller; A storage battery, located inside the ring housing, is used to power the controller and electromagnet.

[0009] Furthermore, both sides of the guide pad are provided with arc-shaped surfaces, and the bracket is provided with a lubrication component for lubricating one side of the arc-shaped surface.

[0010] Furthermore, the lubrication assembly includes: A cavity is disposed inside the support, and the cavity is filled with lubricating oil; A pipe is slidably inserted into one side of the inside of the bracket, and one side of the pipe extends into the cavity; The nozzles are equidistantly arranged on the side of the pipe near the arc-shaped surface; An extrusion assembly is used to force lubricating oil from the cavity into the pipe.

[0011] Furthermore, the extrusion assembly includes: A pressure plate is disposed within the cavity and is connected to the pipeline; A second spring is connected to the side of the pressure plate away from the pipe; An extrusion hole is provided on the pressure plate to connect the cavity to the pipe; A straw is disposed on the outside of the bracket, and the straw is in communication with the cavity; A one-way valve is disposed inside the suction tube and the extrusion orifice; A pushing component is used to push the pipe into the cavity.

[0012] Furthermore, the actuating component includes: A horizontal plate is fixedly connected to one side of the electromagnet; The arc-shaped extrusion surface is symmetrically arranged on one side of the pipe.

[0013] Furthermore, the guide pad is made of hard rubber, and the side of the guide pad near the inner slide of the outer ring matches the shape of the slide.

[0014] Furthermore, the bracket is disposed between the adjacent rollers, and the bracket does not contact the outer ring.

[0015] The technical effects and advantages of this invention are as follows: 1. The present invention enables the fragments to be attracted to the electromagnet when the rollers in the self-aligning roller bearing break, by means of the cooperation between the energized electromagnet extending out of the bracket and the arc-shaped surface of the guide pad provided on its surface, so that the fragments can be removed from the slide and thus prevent the fragments from continuing to move along the slide and scratching the slide. 2. This invention can lubricate the arc-shaped surface on the guide pad, thereby avoiding the situation where the arc-shaped surface is dry and there is a large resistance between it and the fragments, causing the fragments to get stuck on the arc-shaped surface and unable to be successfully attracted to the electromagnet, thus ensuring that the fragments can be smoothly released from the slide.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This invention provides a pedestal self-aligning roller bearing, such as... Figures 1 to 9 As shown, it includes a support 1, an outer ring 2, an inner ring 3, a cage 4, a roller 5, and a collection assembly; Outer ring 2, inner ring 3, cage 4, and roller 5 are the outer ring, inner ring, cage, and roller inside the self-aligning roller bearing in the prior art. Outer ring 2, inner ring 3, cage 4, and roller 5 together form the self-aligning roller bearing. The inner side of the outer ring 2 is provided with a slide with an arc surface. The roller 5 is made of high carbon chromium bearing steel and can contact the slide. The outer ring 2 is fixedly installed inside the support 1, the inner ring 3 is set inside the outer ring 2, the cage 4 is fixed outside the inner ring 3, and the rollers 5 are evenly distributed on the cage 4. The collecting component is used to collect the fragments generated by the broken roller 5 and prevent the fragments from scratching the inner track of the outer ring 2; The collection components include: ring shell 6, bracket 7, electromagnet 8, guide pad 9, and drive assembly; The ring shell 6 is fixed to the outside of the retainer 4. The bracket 7 is fixedly installed at equal intervals on the outside of the ring shell 6. The electromagnet 8 is set inside the bracket 7. After being energized, it has magnetic properties to collect the fragments. The guide pad 9 is fixedly connected to the outside of the electromagnet 8 to ensure that the fragments can be separated from the inner slide of the outer ring 2 when they are attracted to the electromagnet 8. The drive assembly is used to drive the electromagnet 8 to be energized and move it towards the outer ring 2 when the roller 5 breaks.

[0019] When in use, the inner ring 3 is connected to the shaft of the external equipment. When the roller 5 breaks, the resulting fragments will fall onto the slide of the outer ring 2. As the roller 5 is pushed, it moves along the slide. When the staff finds that the roller 5 has broken, they should stop the equipment in time. However, since the shaft will not stop immediately, it will continue to rotate for a period of time before stopping. At this time, the roller 5 pushes the fragments along the slide, causing scratches to the slide. Therefore, when roller 5 breaks, the operator shuts down the equipment and simultaneously energizes electromagnet 8 via the drive assembly, moving it towards the outer ring 2. This causes guide pad 9 to move along with the electromagnet, bringing it into contact with the slide rail. The magnetic force generated by the energized electromagnet 8 attracts the fragments towards it. When the fragments reach the guide pad 9, they are guided away from the slide rail, allowing them to adhere to the side of the electromagnet 8. The fragments then detach from the slide rail and do not come into contact with it, thus preventing them from scratching the slide rail and protecting it.

[0020] like Figures 3 to 4As shown, the drive assembly includes: a rectangular column 11, a first spring 12, a magnetic plate 13, a controller 14, a vibration analyzer 15, and a battery 16; A rectangular column 11 is fixedly connected to the inner wall of the bracket 7. An electromagnet 8 is slidably mounted on the rectangular column 11. The two ends of the first spring 12 are fixedly connected to the rectangular column 11 and the electromagnet 8, respectively. A magnetic plate 13 is fixedly connected to the inner wall of the bracket 7. The magnetic poles of the magnetic plate 13 and the energized electromagnet 8 are in the same direction. A controller 14 is located inside the ring shell 6. The controller 14 can control the electromagnet 8. A vibration analyzer 15 is fixed on the outer side of the outer ring 2. It can detect the breakage of the roller 5. Specifically, when the roller 5 breaks, the fragments are pushed by the roller 5 to rub against the slide rail, which will cause the vibration to intensify. The vibration analyzer 15 periodically detects the vibration amplitude, acceleration, velocity, displacement and spectrum. By comparing the normal state data, abnormal peak values ​​are identified, thus indicating that the roller 5 has broken. The controller 14 is a remote controller. It can remotely receive the signals transmitted by the vibration analyzer 15 and control the energization and de-energization of the electromagnet 8. A battery 16 is located inside the ring shell 6 and is used to power the controller 14 and the electromagnet 8.

[0021] After roller 5 breaks, its fragments fall into the slide rail and are pushed by the other rollers 5, causing abnormal vibration. Vibration analyzer 15 detects the abnormal vibration and, in conjunction with controller 14, controls electromagnet 8 to be energized to make it magnetic. After electromagnet 8 becomes magnetic, it repels magnetic plate 13, thereby driving electromagnet 8 to move rapidly towards the slide rail. At this time, the first spring 12 is stretched and deformed. Finally, electromagnet 8, along with guide pad 9, contacts the inner wall of the slide rail. At this time, electromagnet 8 has not detached from rectangular column 11. When electromagnet 8 is de-energized and loses its magnetism, the first spring 12 resets, thereby resetting electromagnet 8. The magnetism generated when electromagnet 8 is energized can attract fragments between two adjacent rollers 5.

[0022] like Figures 4 to 9 As shown, the guide pad 9 has arc-shaped surfaces 10 on both sides, and the bracket 7 has a lubrication component for lubricating one side of the arc-shaped surface 10.

[0023] The lubrication assembly includes: a cavity, a pipe 17, a nozzle 18, and a compression assembly; The cavity is located inside the support 7 and is filled with lubricating oil. The cavity is located on the side of the support 7 away from the direction of movement. The pipe 17 is slidably inserted into the inside of the support 7 and extends into the cavity. The nozzles 18 are equidistantly arranged on the side of the pipe 17 near the arc surface 10. The extrusion assembly is used to squeeze the lubricating oil in the cavity into the pipe 17.

[0024] If the amount of lubricating oil on the inner wall of the outer ring 2 is insufficient, when the guide pad 9 contacts the slide, the guide pad 9 moves with the movement of the bracket 7. The arc-shaped surface 10 on the guide pad 9 facing the direction of movement will scrape off some lubricating oil, so that the arc-shaped surface 10 on the guide pad 9 facing the direction of movement can be lubricated. Subsequently, when the electromagnet 8 attracts the fragments to the guide pad 9, the fragments can move more smoothly to the surface of the electromagnet 8 along the lubricated arc-shaped surface 10. However, the arc-shaped surface 10 away from the direction of movement cannot scrape off lubricating oil during movement, and its surface is dry. This results in a large frictional resistance between the fragments and the arc-shaped surface 10 away from the direction of movement, which will cause the fragments to get stuck at the arc-shaped surface 10 and not be able to be successfully attracted to the electromagnet 8. Therefore, a lubrication component is provided. During use, when the electromagnet 8 moves rapidly towards the slide, the extrusion component forces the lubricating oil in the cavity into the pipe 17. The lubricating oil entering the pipe 17 is sprayed out from the nozzle 18 onto the arc-shaped surface 10 opposite to the direction of movement, thus lubricating the arc-shaped surface 10. This prevents the fragments from getting stuck on the arc-shaped surface 10 and failing to adhere smoothly to the electromagnet 8 when they move to the arc-shaped surface 10 opposite to the direction of movement, ensuring that the fragments adhere smoothly to the electromagnet 8.

[0025] like Figures 5 to 9 As shown, the extrusion assembly includes: a pressure plate 19, a second spring 20, an extrusion hole 21, a suction tube 22, a one-way valve, and a pushing assembly; The pressure plate 19 is disposed in the cavity and is fixedly connected to the pipe 17. The second spring 20 is fixedly connected to the side of the pressure plate 19 away from the pipe 17. The extrusion hole 21 is disposed on the pressure plate 19 and is used to connect the cavity and the pipe 17. The suction tube 22 is fixedly installed on the outside of the bracket 7 and is connected to the cavity. The one-way valve is disposed inside the suction tube 22 and the extrusion hole 21 (not shown in the figure). The pushing component is used to push the pipe 17 to move into the cavity.

[0026] When the electromagnet 8 is energized and moves rapidly toward the slide, it will work with the pushing component to push the pipe 17 rapidly into the cavity, thereby causing the pressure plate 19 to move along with it, compressing the second spring 20 and causing it to deform and generate force, which in turn squeezes the lubricating oil out of the cavity. At this time, the one-way valve in the suction tube 22 closes and the one-way valve in the extrusion hole 21 opens. As the pressure plate 19 moves, the lubricating oil enters the pipe 17 through the extrusion hole 21, and then quickly fills the pipe 17 and is sprayed out from the nozzle 18 onto the moving guide pad 9 to achieve lubrication.

[0027] like Figures 5 to 9 As shown, the pushing component includes: a horizontal plate 23 and an arc-shaped extrusion surface 24; The horizontal plate 23 is fixedly connected to one side of the electromagnet 8; The arc-shaped extrusion surface 24 is symmetrically arranged on one side of the pipe 17.

[0028] Electromagnet 8 moves towards the slide, causing the horizontal plate 23 to move accordingly. After the horizontal plate 23 comes into contact with the arc-shaped extrusion surface 24, the horizontal plate 23, together with the arc-shaped extrusion surface 24, extrudes the pipe 17, causing the pipe 17 to move into the cavity, thus pushing the pipe 17. As the pipe 17 moves, the pressure plate 19 moves, squeezing the lubricating oil in the cavity outward. When the horizontal plate 23 leaves the pipe 17, there is no lubricating oil in the cavity. Then the second spring 20 resets, taking the pressure plate 19 and the pipe 17 back to their original positions. As the pressure plate 19 resets, air is drawn into the cavity. At this time, the one-way valve in the extrusion hole 21 closes, and the one-way valve in the suction tube 22 opens, allowing outside air to be drawn into the cavity through the suction tube 22. When the electromagnet 8 is reset, the electromagnet 8, together with the horizontal plate 23 and the arc-shaped extrusion surface 24, extrudes the pipe 17. On the same principle, the air in the cavity is expelled. The suction tube 22 is connected to the external lubricating oil delivery pipe in advance. When the horizontal plate 23 leaves the pipe 17, the pressure plate 19 is reset and the lubricating oil is sucked into the cavity by the suction tube 22 for replenishment.

[0029] The nozzle 18 is located on the side of the pipe 17 away from the cavity. When the pipe 17 is pushed, the nozzle 18 moves accordingly, and the lubricating oil can be evenly sprayed onto the arc-shaped surface 10 with the movement of the nozzle 18.

[0030] like Figure 5 As shown, the guide pad 9 is made of hard rubber, and the side of the guide pad 9 near the inner track of the outer ring 2 matches the shape of the track.

[0031] like Figure 2 As shown, the bracket 7 is positioned between adjacent rollers 5, and the bracket 7 does not contact the outer ring 2.

[0032] Working principle: When in use, the inner ring 3 is connected to the rotating shaft of the external equipment. When the roller 5 breaks, the resulting fragments will fall onto the slide of the outer ring 2. As the roller 5 is pushed, it moves along the slide. When the operator discovers that the roller 5 has broken, he stops the equipment in time. However, since the rotating shaft will not stop immediately, it will continue to rotate for a period of time before stopping. At this time, the roller 5 pushes the fragments along the slide, causing scratches to the slide. Therefore, when roller 5 breaks, the staff shuts down the equipment. After roller 5 breaks, its fragments fall into the slide and are pushed by the remaining rollers 5, causing abnormal vibration. Vibration analyzer 15 detects the abnormal vibration. At this time, the controller 14 controls the electromagnet 8 to be energized and made magnetic. After the electromagnet 8 is magnetic, it repels the magnetic plate 13, thereby driving the electromagnet 8 to move quickly towards the slide. At this time, the first spring 12 is stretched and deformed. Finally, the electromagnet 8, with the guide pad 9, contacts the inner wall of the slide. At this time, the electromagnet 8 has not detached from the rectangular column 11. As the electromagnet 8 is energized, the magnetic force will attract the fragments to move towards the electromagnet 8. When the fragments move to the guide pad 9, they will be guided by the arc surface 10 on the guide pad 9 to move away from the slide. This allows the fragments to be attracted to the side of the electromagnet 8 and detach from the slide without contacting it, thus avoiding the fragments scratching the slide and protecting the slide. If the amount of lubricating oil on the inner wall of the outer ring 2 is insufficient, when the guide pad 9 contacts the slide, the guide pad 9 moves with the movement of the bracket 7. The arc-shaped surface 10 on the guide pad 9 facing the direction of movement will scrape off some lubricating oil, so that the arc-shaped surface 10 on the guide pad 9 facing the direction of movement can be lubricated. Subsequently, when the electromagnet 8 attracts the fragments to the guide pad 9, the fragments can move more smoothly to the surface of the electromagnet 8 along the lubricated arc-shaped surface 10. However, the arc-shaped surface 10 away from the direction of movement cannot scrape off lubricating oil during movement, and its surface is dry. This results in a large frictional resistance between the fragments and the arc-shaped surface 10 away from the direction of movement, which will cause the fragments to get stuck at the arc-shaped surface 10 and not be able to be successfully attracted to the electromagnet 8. Therefore, a lubrication assembly is provided. During use, when the electromagnet 8 moves rapidly towards the slide rail, it moves the horizontal plate 23 accordingly. After the horizontal plate 23 contacts the arc-shaped extrusion surface 24, the horizontal plate 23, in conjunction with the arc-shaped extrusion surface 24, extrudes the pipe 17, causing the pipe 17 to move into the cavity, thus pushing the pipe 17. As the pipe 17 moves, it also moves the pressure plate 19, squeezing the lubricating oil outward from the cavity. The pressure plate 19 then moves, compressing the second spring 20 and causing it to deform, generating force. At this time, the one-way valve in the suction tube 22 closes, and the one-way valve in the extrusion hole 21 opens. With the movement of the pressure plate 19, the lubricating oil enters the pipe 17 through the extrusion hole 21, and then quickly... The filling pipe 17 sprays out from the nozzle 18 onto the moving guide pad 9 to lubricate the arc surface 10. This prevents the fragments from getting stuck on the arc surface 10 and failing to adhere to the electromagnet 8 when they move to the arc surface 10 away from the direction of movement. This ensures that the fragments can adhere to the electromagnet 8 smoothly and detach from the slide. When the horizontal plate 23 leaves the pipe 17, there is no lubricating oil in the cavity. Then the second spring 20 resets, along with the pressure plate 19 and the pipe 17. As the pressure plate 19 resets, air is drawn into the cavity. At this time, the one-way valve in the extrusion hole 21 closes and the one-way valve in the suction tube 22 opens, allowing outside air to be drawn into the cavity through the suction tube 22. When maintaining the equipment, after disassembling the outer ring 2, the external support component (which can be a sleeper) is inserted between the electromagnet 8 and the bracket 7. Then, the electromagnet 8 is de-energized to demagnetize it, allowing the debris to be collected. After collection, the electromagnet 8 is energized again to repel the magnetic plate 13. The support component is then removed, and the electromagnet 8 is de-energized. The first spring 12 resets, causing the electromagnet 8 to reset as well. When the electromagnet 8 resets, it works with the horizontal plate 23 and the arc-shaped extrusion surface 24 to expel the air from the cavity. The suction tube 22 is connected to the external lubricating oil delivery pipe in advance. When the horizontal plate 23 leaves the pipe 17, the pressure plate 19 resets, allowing the lubricating oil to be drawn into the cavity through the suction tube 22 for replenishment.
