Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing technology, specifically a single-row roller bearing. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating parts of the machine, reduce the coefficient of friction during movement, and ensure rotational accuracy. Roller bearings are a type of bearing whose rolling elements are cylindrical rollers. The cylindrical rollers make line contact with the raceways, and they have a large radial load capacity.
[0003] Currently, roller bearings typically consist of raceways, rollers, and a cage. The cage has several pockets in which the rollers are housed and can roll. However, after prolonged use, the rollers will wear out, affecting the normal operation of the bearing. Therefore, the rollers need to be replaced. However, when it is necessary to replace the rollers, the raceways and cage must be completely disassembled to remove the worn rollers. Furthermore, during reassembly, all the rollers need to be reset. Therefore, the disassembly and assembly of the rollers is quite troublesome, and replacement is time-consuming and labor-intensive. Utility Model Content
[0004] The purpose of this invention is to provide a single-row roller bearing to solve the above-mentioned problems.

[0006] As a further feature of this utility model, a limiting hole is provided on the cover plate, an insertion hole and a release groove communicating with the insertion hole are provided on the bottom wall of the pocket, and a rotating shaft is provided on the roller, one end of the rotating shaft is used to insert into the limiting hole and the other end is used to insert into the insertion hole.
[0007] As a further feature of this utility model, the connecting assembly includes connecting pieces disposed on both sides of the cover plate, and the retainer is provided with slots on both sides of the disassembly port for the connecting pieces to be inserted. A threaded rod is disposed in the slot, and the connecting piece is provided with a through hole for the threaded rod to pass through. A threaded sleeve for abutting against the connecting piece is threadedly connected to the threaded rod.
[0008] As a further feature of this utility model, the threaded sleeve includes a cap body, the connecting piece has a groove for the cap body to be inserted, and the cap body has a recess.
[0009] As a further feature of this invention, the cover plate is provided with several force-applying grooves.
[0010] As a further feature of this invention, the collar is made of GCr15 steel.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention allows for easy removal of the old roller simply by removing the cover plate from the disassembly port, exposing the port, and then inserting the new roller into the pocket. The disassembly port is then resealed by the cover plate, making the entire disassembly and assembly process more convenient and saving time and effort in replacing the roller.

[0019] 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.
[0020] Please see Figure 1-4As shown, a single-row roller bearing includes a raceway 1 and a cage 2. The raceway 1 is made of GCr15 steel, which has high hardness and high wear resistance, effectively ensuring the strength and wear resistance of the raceway 1 and giving the bearing good durability. The cage 2 has several pockets 3, and rollers 4 are arranged inside the pockets 3. The cage 2 has several disassembly ports communicating with the pockets 3, and several cover plates 5 for closing the disassembly ports are provided on the cage 2. The cover plates 5 are detachably installed on the disassembly ports via connecting components. When any roller 4 wears, the pocket 3 containing that roller 4 can be opened. During operation, simply remove the cover plate 5 from the disassembly port, exposing the disassembly port, and remove the roller 4 through the disassembly port to remove the old roller 4. Then, a new roller 4 is installed into the pocket 3, and the disassembly port is resealed by the cover plate 5. The installation of roller 4 makes the entire disassembly and assembly operation more convenient, thus making the replacement of roller 4 more time-saving and labor-saving. A limiting hole 6 is opened on the cover plate 5, and an insertion hole 7 and a release groove 8 communicating with the insertion hole 7 are opened on the bottom wall of the pocket 3. A rotating shaft 9 is provided on the roller 4, and one end of the rotating shaft 9 is used to insert into the limiting hole 6 and the other end is used to insert into the insertion hole 7. After the roller 4 is installed into the pocket 3, one end of the rotating shaft 9 will be inserted into the limiting hole 6 and the other end will be inserted into the insertion hole 7, thus realizing the rotational connection of roller 4 inside the pocket 3. When it is necessary to disassemble roller 4, the cover plate 5 can be removed first to release the limiting hole 6 from the rotating shaft 9. Then, the roller 4 can be pushed to move so that the other end of the rotating shaft 9 can slide from the insertion hole 7 to the release groove 8, thereby releasing the limiting ring 1 from the roller 4, making it easy to remove roller 4, making the disassembly and assembly of roller 4 more convenient.
[0021] Please see Figure 2-5As shown, the connecting assembly includes connecting pieces 10 disposed on both sides of the cover plate 5. The retainer 2 has slots 11 on both sides of the disassembly opening for the connecting pieces 10 to engage. A threaded rod 12 is disposed within each slot 11. A through hole is formed on the connecting piece 10 for the threaded rod 12 to pass through. A threaded sleeve 13 is threadedly connected to the threaded rod 12 to abut against the connecting piece 10. When the cover plate 5 is installed into the disassembly opening, the connecting piece 10 engages with the slot 11, allowing the threaded rod 12 to pass through the through hole. The threaded sleeve 13 is then threaded onto the threaded rod 12 until it abuts against the connecting piece 10, thus fixing the connecting piece 10 inside the slot 11. This ensures the cover plate 5 is securely installed in the disassembly opening, guaranteeing a sealing effect. When the cover plate 5 needs to be removed, simply unscrew the threaded sleeve 13 from the threaded rod 12 and then pull the connecting piece 10 out of the slot. 11. The cover plate 5 can then be removed from the disassembly port, making the operation relatively convenient and simple. The threaded sleeve 13 includes a cap body 14. A groove 15 for the cap body 14 to be inserted is provided on the connecting piece 10, and a groove is provided on the cap body 14. When the threaded sleeve 13 is threaded onto the threaded rod 12, the cap body 14 will be inserted into the groove 15, thus preventing the cap body 14 from protruding. When it is necessary to unscrew the threaded sleeve 13 from the threaded rod 12, a screwdriver can be inserted into the groove to apply force. The groove can serve as a force point for screwing the threaded sleeve 13, making the disassembly of the threaded sleeve 13 more convenient. Several force-applying grooves 16 are provided on the cover plate 5. When it is necessary to install or remove the cover plate 5 from the disassembly port, a tool can be inserted into the force-applying groove 16 to apply force. The opening of the force-applying groove 16 makes the surface of the cover plate 5 uneven, making it easier to apply force, thus making the disassembly and assembly of the cover plate 5 easier and less strenuous.
