Description

Technical Field

[0001] This utility model relates to the technical field of cage structure for P4 grade 32005 bearings, specifically a cage structure for P4 grade 32005 bearings. Background Technology

[0002] Bearing cages are components of rolling bearings. Their function is to separate the rolling elements inside the bearing, preventing them from colliding and rubbing against each other during operation, thus ensuring smooth operation of the rolling bearing. Bearing cages can be made of different materials, commonly including metals such as steel, copper and copper alloys, and aluminum alloys. In recent decades, with the development of the engineering plastics industry, a large number of high-performance engineering plastics have been researched and developed, and high-performance engineering plastics have been rapidly promoted and used in the field of bearing cages.

[0003] However, it still has some drawbacks. For example, the cage structure of the current P4 grade 32005 bearing is relatively simple during use. Since the cage of most automotive bearings is a complete ring, after long-term use and wear, the bearing cage is prone to damage and needs to be replaced. Therefore, the entire cage needs to be replaced, which increases the replacement cost.

[0004] To address the aforementioned issues, this application proposes a cage structure for a P4-grade 32005 bearing. Utility Model Content

[0005] The purpose of this invention is to provide a cage structure for a P4 grade 32005 bearing, so as to solve the problem of the relatively simple structure in the prior art mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cage structure for a P4 grade 32005 bearing, comprising a first cage and a second cage, wherein a fixing hole is provided on one side of both the first cage and the second cage, and a connecting plate is fixedly installed on the upper and lower outer surfaces of both sides of the first cage, and a fixing block is fixedly installed on one end of the outer surface of the connecting plate.

[0007] Preferably, a limiting groove is provided at one end of the fixing block, connecting blocks are fixedly installed on both outer surfaces of the first retainer, a first spring is fixedly connected to both outer surfaces of the connecting blocks, and a locking block is fixedly installed on one outer surface of the first spring.

[0008] Preferably, mounting grooves are provided on the upper and lower outer surfaces of both sides of the second retainer, and locking holes and movable grooves are provided on the outer walls of both sides of the second retainer. The movable grooves are located at the upper and lower ends of the locking holes, and sliding buttons are movably installed in the inner cavity of the movable grooves.

[0009] Preferably, a connecting rod is fixedly connected to the outer surface of one end of the sliding button, a limit block is fixedly installed at one end of the connecting rod, and a second spring is fixedly installed at the other end of the sliding button.

[0010] Preferably, the second retainer has connecting grooves on both sides, the connecting block is detachably connected to the inner cavity of the connecting groove, and the fixing block is slidably connected to the inner cavity of the mounting groove.

[0011] Preferably, the card block engages with the inner cavity of the card hole.

[0012] Preferably, the second spring is fixedly located in the inner cavity of the movable groove, and the limiting block is engaged with the inner cavity of the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a first and second cage structure, allowing for detachable connection between the cage and the connecting block and connecting groove, and between the fixing block and mounting groove. This design simplifies installation and disassembly, enhances the flexibility of the cage structure, and achieves a stable connection between the cages through the interlocking structure of the locking block and locking hole, as well as the interlocking structure of the limiting block and limiting groove. This dual locking mechanism strengthens the overall stability of the cage, improving its durability and service life. The design of the first and second springs allows the locking block and limiting block to flexibly engage and disengage from their respective slots, enhancing the adaptability and ease of use of the cage structure. A sliding button installed in the movable groove allows users to easily operate the locking and disengaging of the limiting block, simplifying the cage assembly and disassembly process and improving work efficiency. When a part of the bearing is worn or damaged, it is not necessary to replace the entire cage; only the damaged part needs to be replaced. This design reduces maintenance costs and improves resource utilization efficiency, enhancing both structural stability and durability, reducing maintenance costs, and increasing adaptability.

[0021] Please see Figures 1-2 This utility model provides a technical solution: a cage structure for a P4 grade 32005 bearing, including a first cage 1 and a second cage 2. Each of the first cage 1 and the second cage 2 has a fixing hole 3 on one side. Connecting plates 4 are fixedly installed on the upper and lower outer surfaces of both sides of the first cage 1. A fixing block 5 is fixedly installed on one end of the outer surface of the connecting plate 4, and a limit groove 6 is formed at one end of the fixing block 5. Connecting blocks 7 are fixedly installed on both sides of the outer surface of the first cage 1. A first spring 8 is fixedly connected to both sides of the outer surface of the connecting block 7. A locking block 9 is fixedly installed on one side of the outer surface of the first spring 8. The second retainer 2 has connecting grooves on both sides. The connecting block 7 is detachably connected to the inner cavity of the connecting groove, and the fixing block 5 is slidably connected to the inner cavity of the mounting groove 10. Through the structure of the first retainer 1 and the second retainer 2, the two can be detachably connected by the cooperation of the connecting block 7 with the connecting groove and the fixing block 5 with the mounting groove 10. This design not only simplifies the installation and disassembly process, but also improves the flexibility of the retainer structure. This design reduces maintenance costs and improves resource utilization efficiency.

When a part of the bearing wears or When damaged, the entire cage does not need to be replaced; only the damaged part needs to be replaced. The locking mechanism between the locking block 9 and the locking hole 11, as well as the locking mechanism between the limiting block 15 and the limiting groove 6, achieves a stable connection between the cages. This dual locking mechanism enhances the overall stability of the cage and improves its durability and service life. The limiting block 15 engages with the inner cavity of the limiting groove 6. The other end of the sliding button 13 is fixedly installed with a second spring 16, which is fixedly located in the inner cavity of the movable groove 12. The design of the first spring 8 and the second spring 16 allows the locking block 9 and the limiting block 15 to flexibly engage and disengage from the corresponding holes and grooves, enhancing the adaptability and ease of use of the cage structure.

[0023] Working principle:

[0024] The structure of the first cage 1 and the second cage 2 allows for detachable connection through the cooperation of the connecting block 7 and the connecting groove, and the fixing block 5 and the mounting groove 10. This design not only simplifies the installation and disassembly process but also improves the flexibility of the cage structure. The locking mechanism of the locking block 9 and the locking hole 11, and the locking mechanism of the limiting block 15 and the limiting groove 6, achieves a stable connection between the cages. This dual locking mechanism enhances the overall stability of the cage, improving its durability and service life. The design of the first spring 8 and the second spring 16 allows the locking block 9 and the limiting block 15 to flexibly engage and disengage from their respective slots, enhancing the adaptability and ease of use of the cage structure. The sliding button 13 installed in the movable groove 12 allows users to easily operate the locking and disengaging of the limiting block 15, thus simplifying the cage assembly and disassembly process and improving work efficiency. When a part of the bearing is worn or damaged, it is not necessary to replace the entire cage; only the damaged part needs to be replaced.
