Description

Technical Field

[0001] This utility model relates to the field of bearing cage technology, and in particular to a cylindrical roller bearing cage. Background Technology

[0002] Cylindrical roller bearing cages are parts that partially or completely enclose the rollers in a cylindrical roller bearing. Their main function is to isolate the rollers from direct contact, thereby reducing friction and wear, while also guiding the rollers to move stably within the bearing and maintaining their position. In cylindrical roller bearings, the cage is usually designed as a ring structure with several pockets distributed circumferentially to accommodate the rollers, and adjacent pockets are connected by cage beams.

[0003] In existing technologies, some cylindrical roller bearing cage devices have pockets formed by adjacent window beams to accommodate the rollers. The diameter and depth of the pockets need to be slightly larger than the roller size to ensure flexible rotation, thereby isolating the rollers, maintaining the uniform distribution of the rollers, and avoiding direct collisions between the rolling elements, thus reducing friction and noise. However, in some cylindrical roller bearing cage devices, when the rollers are worn and need to be replaced, the bearing cage is fixed as one piece, which is inconvenient for workers to disassemble the rollers, causing inconvenience to the workers. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A cylindrical roller bearing cage includes a first ring, a locking block fixedly connected to one side of the first ring, a groove first formed at the bottom of the locking block, an elastic telescopic rod fixedly connected to the inner wall of the groove first, a second ring provided at one end of the locking block, an insert block fixedly connected to one side of the second ring, a triangular stop block fixedly connected to the outside of the insert block, an insertion hole formed inside the insert block, pocket holes formed inside the first and second rings, and rotating holes formed on the outside of the first and second rings. A cylindrical roller is rotatably connected inside the rotating hole for easy disassembly of the cylindrical roller.

[0006] As a further description of the above technical solution:

[0007] The outer side of the ring is provided with a disk, and multiple guide rods are fixedly connected to the outer side of the disk for aligning the position of the slide rod.

[0008] As a further description of the above technical solution:

[0009] The outer side of the disk is fixedly connected to a ring column three, and the outer side of the disk is rotatably connected to a rotating shaft to make the rotation of the rotating shaft more stable.

[0010] As a further description of the above technical solution:

[0011] The outer side of the circular column three is fixedly connected to a fixing plate, and the outer side of the fixing plate is rotatably connected to a disk two. The inner side of the disk two is fixedly connected to the outside of the rotating shaft, which is used to drive the disk two to rotate.

[0012] As a further description of the above technical solution:

[0013] The outer side of the second disc is provided with a curved groove, and a slide rail is provided on one side of the second disc for pressing the slide rod.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the curved slide groove 2 is slidably connected to a slide rod, and the outside of the slide rod is fixedly connected to an insert rod, which is slidably connected to the inner wall of the slide rail for compressing the elastic telescopic rod.

[0016] As a further description of the above technical solution:

[0017] The rotating shaft passes through the outer ring cylinder and is rotatably connected to the outer side of the disk. A handle is fixedly connected to one end of the rotating shaft for easy rotation.

[0018] As a further description of the above technical solution:

[0019] The cylindrical roller is rotatably connected to the inside of the pocket, the insert block is slidably connected to the inner wall of the groove, and one end of the elastic telescopic rod is slidably connected to the inner wall of the insert hole to allow the cylindrical roller to rotate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, one end of the cylindrical roller is inserted into the rotating hole, and the insert block is inserted into the sliding groove. The triangular stop block squeezes the elastic telescopic rod. When the elastic telescopic rod passes the triangular stop block, it begins to rebound and is inserted into the insert hole to fix the first and second rings. The subsequent squeezing of the elastic telescopic rod makes it easy to disassemble the first and second rings, thus facilitating the replacement of the cylindrical roller by the staff.

[0022] 2. In this utility model, holding the handle drives the rotating shaft to rotate, which in turn drives the second disc to rotate. The second disc then drives the second curved slide groove to move. As the second curved slide groove moves, the slide rod slides along the second curved slide groove, thereby driving the insertion rod to slide in the slide rail. The insertion rod extends out of the slide rail, inserts into the insertion hole, and squeezes the elastic telescopic rod, thus achieving the effect of facilitating the disassembly of the first and second rings.

Detailed Implementation

[0033] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a cylindrical roller bearing cage, comprising a ring 1, a locking block 2 fixedly connected to one side of the ring 1, a groove 3 at the bottom of the locking block 2, an elastic telescopic rod 4 fixedly connected to the inner wall of the groove 3, a ring 5 at one end of the locking block 2, an insert block 6 fixedly connected to one side of the ring 5, a triangular stop block 7 fixedly connected to the outside of the insert block 6, an insertion hole 8 inside the insert block 6, pocket holes 9 inside the ring 1 and the ring 5, and a rotating hole outside the ring 1 and the ring 5, into which a cylindrical roller 10 is rotatably connected for easy disassembly of the cylindrical roller 10.

[0035] Reference Figure 2 , Figure 3 and Figure 8 The cylindrical roller 10 is externally rotatably connected to the inside of the pocket 9, the insert block 6 is externally slidably connected to the inner wall of the groove 3, and one end of the elastic telescopic rod 4 is slidably connected to the inner wall of the insertion hole 8 to allow the cylindrical roller 10 to rotate.

[0036] Reference Figure 1 , Figure 6 and Figure 7 The outer side of the ring 1 is provided with a disc 11. Multiple guide rods 12 are fixedly connected to the outer side of the disc 11 for aligning the position of the slide rod 19. The outer side of the disc 11 is fixedly connected with a ring column 3 13. The outer side of the disc 11 is rotatably connected with a rotating shaft 14 for making the rotation of the rotating shaft 14 more stable. The outer side of the rotating shaft 14 passes through the ring column 3 13 and is rotatably connected to the outer side of the disc 11. One end of the rotating shaft 14 is fixedly connected with a handle 15 for convenient rotation of the rotating shaft 14.

[0037] Reference Figure 6 , Figure 7 A fixed plate 16 is fixedly connected to the outside of the ring column 13. A disc 17 is rotatably connected to the outside of the fixed plate 16. The inside of the disc 17 is fixedly connected to the outside of the rotating shaft 14 to drive the disc 17 to rotate. A curved groove 18 is provided on the outside of the disc 17. A slide rail 21 is provided on one side of the disc 17 to compress the slide rod 19. The slide rod 19 is slidably connected to the inner wall of the curved groove 18. An insert rod 20 is fixedly connected to the outside of the slide rod 19. The insert rod 20 is slidably connected to the inner wall of the slide rail 21 to compress the elastic telescopic rod 4.

[0038] Working principle: One end of the cylindrical roller 10 is inserted into the rotating hole of the ring 1, and the insert block 6 is inserted into the groove 3. The insert block 6 slides along the groove 3. When the insert block 6 slides in the groove 3, the triangular stop 7 connected to the insert block 6 will squeeze the elastic telescopic rod 4 connected to the groove 3, causing the elastic telescopic rod 4 to deform. After the triangular stop 7 passes the elastic telescopic rod 4, the elastic telescopic rod 4 begins to rebound, and one end of the elastic telescopic rod 4 will be inserted into the insertion hole 8. At this time, the elastic telescopic rod 4 is behind the triangular stop 7, thereby fixing the ring 1 and the ring 5, and fixing the cylindrical roller 10 in the pocket 9, avoiding direct collision between the cylindrical rollers 10, thereby reducing friction and noise, and guiding the cylindrical roller 10 to move stably in the pocket 9 and maintain its position.

[0039] When the cylindrical roller 10 is severely worn and it is necessary to disassemble the first ring 1 and the second ring 5 to replace the cylindrical roller 10, place the first disc 11 in the middle of the first ring 1 and the second ring 5, align the guide rod 12 with the edge of the insertion hole 8 to facilitate the insertion rod 20 to be inserted into the insertion hole 8, hold the handle 15 and rotate the rotating shaft 14. The rotating shaft 14 drives the second disc 17 to rotate, thereby driving the second curved groove 18 to rotate. The insertion rod 20 connected to the slide rod 19 is in the slide rail 21. When the second curved groove 18 rotates, it squeezes the slide rod 19, causing it to move along the second curved groove 18, allowing the insertion rod 20 to slide along the slide rail 21, allowing the insertion rod 20 to drill out of the slide rail 21, thereby inserting the insertion rod 20 into the insertion hole 8, squeezing the elastic telescopic rod 4, causing the elastic telescopic rod 4 to deform. Then, reverse the above operation to separate the first ring 1 and the second ring 5, thereby facilitating the replacement of the severely worn cylindrical roller 10.

[0040] 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.
