Description

Technical Field

[0001] This utility model belongs to the field of roller bearing technology, specifically relating to a pressure-resistant roller. Background Technology

[0002] Pressure rollers are high-load-bearing rolling elements, typically made of alloy steel or high-strength materials, with a hardened surface treatment, exhibiting excellent compressive strength, wear resistance, and fatigue resistance. Their cylindrical or drum-shaped design effectively distributes pressure, making them suitable for low-speed, heavy-load conditions. They are commonly found in bearings or transmission structures in mining machinery, metallurgical equipment, and heavy-duty conveying systems, enabling stable operation in harsh environments, reducing frictional loss, and extending equipment lifespan.

[0003] Currently, after pressure rollers are assembled with the inner and outer rings of the bearing via cages, their surfaces require frequent replenishment of grease during use. However, existing grease filling methods primarily rely on manual application of grease directly to the contact area between the rollers and the cage. This method has significant drawbacks: firstly, it is difficult to precisely control the amount of grease used, and excessive application can lead to poor overall heat dissipation in the bearing; secondly, insufficient grease can affect the normal operation of the rollers and even accelerate wear.

[0004] To address the aforementioned problems, this application proposes a pressure-resistant roller. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a pressure-resistant roller, comprising an outer ring, an inner ring, a lubrication retention mechanism, and multiple rollers. The multiple rollers are arranged in a ring array within multiple grooves on the inner side of the lubrication retention mechanism, and the multiple rollers are disposed between the outer ring and the inner ring.

[0006] The lubrication retention mechanism includes a first retaining ring and a second retaining ring. Multiple storage boxes and multiple insert blocks are respectively arranged in a circular array on the inner side of the first retaining ring and the second retaining ring. Multiple oil outlet holes are respectively opened on both sides of the storage box. The front end of the insert block is provided with a tapered inclined surface, and the front end of the insert block is inserted into the inner side of the storage box.

[0007] Preferably, the insert block has movable grooves on both sides near the front end, and an oil hole scraping mechanism is provided on the inner side of the movable groove.

[0008] Preferably, the oil hole scraping mechanism includes two connecting seats, a fixed plate and a fixed ring, with a rotating rod rotatably connected to the inner side of the two connecting seats, and a scraper fixedly installed on the left or right side of the rotating rod.

[0009] Preferably, the upper part of the connecting seat is provided with a rotating cavity, and the upper end of the rotating rod extends into the rotating cavity provided inside the upper connecting seat. A guide ring is fixedly installed on the inner side of the rotating cavity and on the outer side of the rotating rod by a fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the lubrication retention mechanism is designed with a combination of a quantitative storage box and a cartridge block with a tapered inclined surface. This design allows for precise control of the amount of grease applied each time, avoiding both poor bearing heat dissipation due to excessive grease and insufficient lubrication that could affect the normal operation of the rollers and accelerate wear. Furthermore, the lubrication retention mechanism employs a cartridge-type quick-release locking structure, significantly improving subsequent maintenance efficiency. In addition, the oil hole scraping mechanism on both sides of the cartridge block automatically cleans the oil outlet holes on both sides of the storage box during the movement of the cartridge block using a flexible rotating scraper, effectively preventing clogging of the oil outlet holes.

However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0028] Please see Figures 1-6 The present invention provides the following technical solution: a pressure-resistant roller, comprising an outer ring 1, an inner ring 2, a lubrication retention mechanism and a plurality of rollers 3, characterized in that the plurality of rollers 3 are arranged in a ring array in a plurality of pockets inside the lubrication retention mechanism, and the plurality of rollers 3 are disposed between the outer ring 1 and the inner ring 2.

[0029] The lubrication mechanism includes a first retaining ring 4 and a second retaining ring 5. Multiple storage boxes 6 and multiple insert blocks 7 are respectively arranged in a circular array on the inner sides of the first retaining ring 4 and the second retaining ring 5. Multiple oil outlet holes 8 are respectively opened on both sides of the storage boxes 6. A tapered inclined surface 9 is provided at the front end of the insert block 7, and the front end of the insert block 7 is inserted into the inner side of the storage box 6. A fixing groove 18 is opened on the left side of the first retaining ring 4, and the inner side of the fixing groove 18 is threaded into the outer surface of the right end of the fixing ring 17. Multiple movable grooves are evenly opened on the left end of the fixing ring 17, and fixing blocks 19 are fixedly installed in the multiple movable grooves of the fixing ring 17. The front end of the insert block 7 passes through a corresponding sliding opening inside the first retaining ring 4, and a fixing hole is opened on the left side of the front end of the insert block 7 for insertion into the fixing block 19.

[0030] When it is necessary to apply grease to the roller 3, first rotate the retaining ring 17 so that the multiple retaining blocks 19 installed on the retaining ring 17 are removed from the corresponding retaining holes of the insert block 7. Then, remove the second retaining ring 5 and the multiple insert blocks 7 connected to it as a whole from the inner side of the outer ring 1 and the storage box 6. After removal, fill each storage box 6 with an appropriate amount of grease in turn. The storage space opened inside the storage box 6 should be strictly consistent with the replenishment requirements of the roller 3 each time, so as to ensure precise control of the amount of grease used.

[0031] After filling, the second retaining ring 5 and the insert block 7 are reassembled into the first retaining ring 4 and the storage box 6. Since the front end of the insert block 7 is designed with a tapered inclined surface 9, the grease will be squeezed and move preferentially along the inclined surface during the pushing process. This design takes advantage of the low resistance of the inclined path, thereby effectively guiding the grease to flow out evenly from the oil outlet holes 8 on both sides of the storage box 6, ensuring that the grease can be evenly distributed on both sides of the roller 3. When the insert block 7 is fully inserted and passes through the sliding port of the first retaining ring 4, the fixing ring 17 needs to be rotated again to reset it. At this time, the fixing block 19 on the fixing ring 17 will be re-inserted into the fixing hole on the left side of the insert block 7, completing the fixing and locking of the entire assembly.

[0032] The insert block 7 has movable grooves 10 on both sides near the front end. The inner side of the movable groove 10 is provided with an oil hole scraping mechanism. The oil hole scraping mechanism includes two connecting seats 11, a fixing plate 13 and a fixing ring 17. The inner side of the two connecting seats 11 is rotatably connected to a rotating rod 12. A scraper 20 is fixedly installed on the left or right side of the rotating rod 12. The upper connecting seat 11 has a rotating cavity. The upper end of the rotating rod 12 extends into the rotating cavity opened inside the upper connecting seat 11. The inner side of the rotating cavity and the outer side of the rotating rod 12 is fixedly installed by the fixing plate 13. The upper left side of the rotating rod 12 is fixedly installed with a rotating plate 15. The inner side of the rotating plate 15 slides with the outer surface of the guide ring 14. The outer surface of the guide ring 14 and the inner side of the rotating plate 15 and the fixing plate 13 are respectively fixedly installed with arc springs 16.

[0033] During the movement of the insert block 7 inside the storage box 6: whenever the scraper 20 moves to the position of the oil outlet 8, under the elastic force of the arc spring 16, the rotating rod 12 will drive the scraper 20 to rotate 90 degrees to scrape the oil outlet 8, effectively preventing grease residue from clogging it. When the insert block 7 is removed from the storage box 6, the scraper 20 will reset under the action of elastic pressure and rotate 90 degrees in the opposite direction, thus smoothly moving out of the storage box 6. The oil outlet scraping mechanism ensures that the oil outlet 8 remains unobstructed for a long time, ensuring the stable operation of the lubrication system.

[0034] When using the roller 3, first rotate the retaining ring 17 to make the multiple retaining blocks 19 installed on the retaining ring 17 exit from the corresponding retaining holes of the insert block 7. Then, remove the second retaining ring 5 and the multiple insert blocks 7 connected to it from the inner side of the outer ring 1 and the storage box 6 as a whole. After removal, fill each storage box 6 with an appropriate amount of grease in turn. The storage space opened inside the storage box 6 should be strictly consistent with the replenishment requirements of the roller 3 each time, so as to ensure precise control of the amount of grease used.

[0035] After filling is completed, the second retaining ring 5 and the insert block 7 are reassembled into the first retaining ring 4 and the storage box 6. Since the front end of the insert block 7 is designed with a tapered inclined surface 9, the grease will be squeezed and move preferentially along the inclined surface during the pushing process. This design takes advantage of the small resistance of the inclined surface path, thereby effectively guiding the grease to flow out evenly from the oil outlet holes 8 on both sides of the storage box 6, ensuring that the grease can be evenly distributed on both sides of the roller 3.

[0036] After the insert block 7 is fully inserted and passes through the sliding port of the first retaining ring 4, the retaining ring 17 needs to be rotated again to reset it. At this time, the retaining block 19 on the retaining ring 17 will be re-inserted into the retaining hole on the left side of the insert block 7 to complete the fixing and locking of the entire assembly. In subsequent operations, simply rotate the outer ring 1 to drive the roller 3 to rotate, so that the grease attached to the surface of the roller 3 is evenly applied to the inner side of the outer ring 1, the outer side of the inner ring 2, and the rolling contact surface of the roller 3 itself.

[0037] To ensure long-term reliability, an oil hole scraping mechanism is specially provided on both sides of the front end of the insert block 7. This mechanism plays a role during the movement of the insert block 7: whenever the scraper 20 moves to the position of the oil outlet 8, under the elastic force of the arc spring 16, the rotating rod 12 will drive the scraper 20 to rotate 90 degrees to scrape the oil outlet 8, effectively preventing grease residue from clogging it. When the insert block 7 is removed from the storage box 6, the scraper 20 will reset under the elastic pressure and rotate 90 degrees in the opposite direction, thus smoothly moving out of the storage box 6. The setting of the oil hole scraping mechanism ensures that the oil outlet 8 remains unobstructed for a long time, ensuring the stable operation of the lubrication system.

[0038] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
