Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to externally guided self-aligning roller bearings. Background Technology

[0002] Self-aligning roller bearings are a type of rolling bearing with a spherical outer ring raceway. They have self-aligning properties and can automatically compensate for coaxiality errors. When the shaft or bearing housing becomes misaligned due to installation errors, stress deformation, or temperature changes, the relative movement between the bearing's spherical raceway and the rollers can automatically adjust the shaft position, compensate for coaxiality errors, and prevent additional stress and wear caused by misalignment, thus ensuring the normal operation of the bearing.

[0003] The outer guide cage has a large contact area with the outer ring, and the guide surface is usually hardened to reduce friction and wear. At the same time, when there is insufficient grease or contaminants such as dust and debris, the outer guide structure can reduce the probability of impurities entering the gap between the cage and the raceway, thus extending the bearing life.

[0004] In existing technologies, externally guided self-aligning roller bearings typically require methods such as tapping with a copper rod to disassemble and install the bearing. This can cause axial displacement of the rollers during installation, resulting in uneven clearance between the rollers and the outer ring. Consequently, the bearing may wobble during operation, exacerbating roller wear. Utility Model Content

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3This utility model provides an embodiment of an externally guided self-aligning roller bearing, comprising a guide plate 1, a push rod 2 slidably connected to the inner wall of the guide plate 1, a mounting plate 3 slidably connected to the outer wall of the push rod 2, a buckle 4 fixedly connected to the lower surface of the mounting plate 3, the inner wall of the buckle 4 engaging with the inner wall of the guide plate 1, a bolt 5 threadedly connected to the inner wall of the mounting plate 3, the outer wall of the bolt 5 slidably connected to the outer wall of the push rod 2, a fixing post 6 slidably connected to the outer wall of the push rod 2, the outer wall of the fixing post 6 fixedly connected to the outer wall of the guide plate 1, a rotating rod 7 rotatably connected to the inner wall of the fixing post 6, a rotating rod 8 rotatably connected to the outer wall of the rotating rod 7, and a push block 9 rotatably connected to the outer wall of the rotating rod 8. The inner wall of push block 9 is fixedly connected to the bottom end of push rod 2. Spring 10 is provided on the upper surface of push block 9. The upper surface of spring 10 is fixedly connected to the outer wall of fixed column 6. Self-aligning assembly is provided on the outer wall of guide plate 1. Self-aligning assembly includes outer ring 11. Both outer walls of outer ring 11 can be detachably installed on the outer wall of guide plate 1. The inner wall of outer ring 11 is slidably connected to the outer wall of fixed column 6. The inner wall of outer ring 11 is provided on the outer wall of rotating rod 7. The outer wall of push block 9 is slidably connected to the inside of outer ring 11. Inner ring 12 is provided on the inner wall of outer ring 11. Roller body 13 is provided on the outer wall of inner ring 12. The outer wall of roller body 13 is slidably connected to the outer wall of guide plate 1.

[0026] Specifically, by installing the roller body 13 onto the outer wall of the inner ring 12, and then installing the inner ring 12 and the roller body 13 onto the inner wall of the outer ring 11, the self-aligning roller bearing can be quickly assembled. By installing the guide plate 1 onto the outer walls of the outer ring 11 and the inner ring 12, the guide plate 1 drives the fixing column 6 to be installed onto the inner wall of the outer ring 11, thus achieving the effect of external guidance to prevent bearing misalignment. By installing the mounting plate 3 onto the inner wall of the guide plate 1, the push rod 2 is pulled to drive the push block 9 to slide, causing the push block 9 to drive the rotating rod 8 to rotate, and the rotating rod 8 will drive the rotating rod 7 to rotate. The rotating rod 7, located on the inner wall of the fixed column 6, can quickly lock the outer ring 11. When the push block 9 slides, it compresses the spring 10, which is fixed to the outer wall of the fixed column 6, providing power for the push block 9 to reset. When the push rod 2 slides to the appropriate position and the rotating rod 7 locks the outer ring 11, the bolt 5 is rotated to lock the push rod 2, achieving a quick self-locking effect. The rotating rod 7 allows the bearing to be evenly stressed during installation while preventing the bearing from wobbling during operation, thus extending the service life of the roller body 13.

[0027] Reference Figure 1 , Figure 2 and Figure 4An oil storage box 14 is provided on the inner wall of the outer ring 11. A box cover 15 is detachably installed on the upper surface of the oil storage box 14. A pressing block 16 is slidably connected to the outer wall of the box cover 15. The outer wall of the pressing block 16 is slidably connected to the inner wall of the oil storage box 14. A push post 17 is fixedly connected to the inner wall of the pressing block 16. The outer wall of the push post 17 is slidably connected to the inner wall of the box cover 15. A spring 18 is provided on the upper surface of the box cover 15. The upper surface of the spring 18 is fixedly connected to the inner wall of the pressing block 16. A slider 19 is fixedly connected to the bottom end of the push post 17. A locking post 20 is fixedly connected to the inner wall of the slider 19. A guide rod 22 is slidably connected to the outer wall of the locking post 20. The outer wall of the guide rod 22 is rotatably connected to the inner wall of the slider 19.

[0028] Specifically, by installing the oil reservoir 14 onto the inner wall of the outer ring 11, and then placing the grease inside the oil reservoir 14, the cover 15 is installed onto the inner wall of the oil reservoir 14. Pushing the pressing block 16 causes the push post 17 to slide on the inner wall of the cover 15. The pressing block 16 compresses the spring 18, and the pressing block 16 slides on the inner walls of the cover 15 and the oil reservoir 14, allowing the pressing block 16 to quickly reset while preventing it from falling off. The push post 17 drives the slider 19 to slide, causing the slider 19 to drive the locking post 20 to slide synchronously. The guide rod 22 slides on the inner wall of the guide rod 22, allowing the locking post 20 to achieve the effect of the guide rod 22 rotating. The guide rod 22 rotates on the inner wall of the slider 19 and the inner wall of the cover 15, thus preventing the guide rod 22 from falling off.

[0029] Reference Figure 4 A push plate 21 is rotatably connected to the outer wall of the guide rod 22. The upper surface of the push plate 21 is fixedly connected to the lower surface of the slider 19. The outer wall of the push plate 21 is slidably connected to the inner wall of the oil storage box 14. The outer wall of the guide rod 22 is rotatably connected to the inner wall of the box cover 15. A cross buckle 23 is snapped into the inner wall of the guide rod 22. A rotating column 24 is fixedly connected to the lower surface of the cross buckle 23. An oil discharge plate 25 is rotatably connected to the outer wall of the rotating column 24. The outer wall of the oil discharge plate 25 is fixedly connected to the inner wall of the oil storage box 14. An auger blade 26 is fixedly connected to the outer wall of the rotating column 24. The outer wall of the auger blade 26 is rotatably connected to the inner wall of the oil storage box 14.

[0030] Specifically, by installing the oil discharge plate 25 onto the inner wall of the oil reservoir 14, the rotating column 24 drives the auger blade 26 to rotate on the inner wall of the oil discharge plate 25, and the auger blade 26 rotates on the inner wall of the oil reservoir 14, enabling the auger blade 26 to achieve a stable feeding effect. By installing the cross buckle 23 onto the upper surface of the rotating column 24, and the guide rod 22 being locked on the outer wall of the cross buckle 23, the guide rod 22 drives the rotating column 24 to rotate synchronously. By using the slider 19 to drive the push plate 21 to slide on the inner wall of the cover 15 and the oil reservoir 14, the push plate 21 can achieve a stable grease dispensing effect. The grease is fed by the auger blade 26 through the oil discharge plate 25, allowing the auger blade 26 to stably allow the grease to enter the outer wall of the roller body 13 through the oil reservoir 14. The auger blade 26 can evenly spread the grease on the outer wall of the roller body 13 by pressing, achieving the effect of convenient application operation while improving the overall performance of the bearing.

[0031] Working principle: When the bearing is needed, the inner ring 12 and roller body 13 are installed on the inner wall of the outer ring 11, and the oil reservoir 14 is installed on the outer wall of the outer ring 11. Rotating the inner ring 12 drives the roller body 13 to rotate, which in turn pushes the pressing block 16 to slide the push post 17. The push post 17 pushes the slider 19 to slide while compressing the spring 18. The push post 17 slides on the inner wall of the cover 15, which can prevent the slider 19 from falling off and achieve a quick reset effect. The slider 19 drives the locking post 2. The guide rod 22 slides on the outer wall of the guide rod 22, causing it to rotate on the inner wall of the slider 19 and the cover 15. This ensures stable rotation of the guide rod 22. Lubricant is placed inside the oil reservoir 14, and the cover 15 is then installed on its upper surface. Simultaneously, the guide rod 22 engages with the cross buckle 23, which is fixed to the inner wall of the rotating column 24. This allows the guide rod 22 to drive the rotating column 24 to rotate synchronously. The rotating column 24 then drives the auger blade 26 to rotate, causing the slider 19 to push the pusher plate 2. 1. The sliding action, combined with the auger blade 26, achieves a stable application of grease to the outer wall of the roller body 13. Guide plate 1 drives the fixed post 6 to slide on the inner wall of the outer ring 11, causing the mounting plate 3 to engage with the buckle 4 and be installed on the inner wall of guide plate 1. This allows for quick positioning and installation of guide plate 1 while preventing push rod 2 from shifting. Pushing and pulling push rod 2 causes push block 9 to slide, compressing spring 10 and rotating rod 8, allowing push block 9 to quickly reset. Rotating rod 8 causes rotating rod 7 to rotate on the inner wall of fixed post 6, enabling rotating rod 7 to quickly self-lock. When rotating rod 7 locks onto outer ring 11, rotating bolt 5 locks push rod 2, preventing guide plate 1 from falling off. This bearing not only ensures even force distribution during installation and prevents bearing sway during operation, extending the service life of roller body 13, but also allows for even application of grease to the outer wall of roller body 13 through pressing, facilitating application and improving overall bearing performance.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
