[0001] This utility model relates to the field of bearing cage technology, and in particular to a bearing cage that is easy to disassemble and assemble. Background Technology

[0002] As a core component of mechanical transmission, bearings directly affect the operating efficiency and lifespan of equipment. Cages, as an important part of bearings, are mainly used to evenly separate rolling elements (such as balls and rollers), reduce friction, and guide their movement. With the development of industrial automation, split-type cages are becoming increasingly common, but traditional structures still have significant drawbacks in terms of ease of assembly and disassembly and connection reliability.

[0003] Traditional split-type cages mostly use bolts or rivets for connection. Rivet connections offer high stability, but each disassembly and assembly takes a long time and requires a special screwdriver. In addition, bolted connections are prone to loosening due to vibration, and the cage bolts have a high loosening rate after the bearing has been running for a long time, which can lead to rolling element jamming.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A bearing cage that is easy to assemble and disassemble includes a first retaining half-cage and a second retaining half-cage. The first retaining half-cage includes a first annular frame and a first arc-shaped baffle. The first arc-shaped baffle is evenly arranged on one side of the first annular frame along the circumferential direction and is integrally formed with the first annular frame. A plurality of insertion tubes are evenly installed on the inner side of the first annular frame. The insertion tubes are integrally formed with the first annular frame. The second retaining half-cage is sleeved on the insertion tubes and is fixed to the insertion tubes by a locking member. A safety member is also inserted into the locking member.

[0007] As a preferred embodiment, the second half-frame includes a second annular frame and a second arc-shaped baffle. The second arc-shaped baffle is evenly disposed on one side of the second annular frame along the circumferential direction, and the second arc-shaped baffle is integrally formed with the second annular frame.

[0008] As a preferred embodiment, the second annular frame is provided with a plurality of insertion holes for inserting and installing the insertion pipe, and the insertion holes are evenly distributed along the circumference of the second annular frame.

[0009] As a preferred embodiment, the locking component includes an outer plate and elastic claws. There are two sets of elastic claws, and the two sets of elastic claws are symmetrically installed on one side of the outer plate. The elastic claws are integrally formed with the outer plate.

[0010] As a preferred embodiment, the elastic claw includes a strip plate, a triangular block, and an arc-shaped wrench. The triangular block is disposed at one end of the strip plate, and the arc-shaped wrench is installed on the inner side of the triangular block. The strip plate, the triangular block, and the arc-shaped wrench are integrally formed.

[0011] As a preferred embodiment, the safety component includes an outer cover and an I-beam frame, the I-beam frame being fixedly installed on the inner side of the outer cover and inserted between two sets of elastic claws.

[0012] As a preferred embodiment, two sets of guide grooves for installing the triangular locking blocks are symmetrically opened on the inner side of the insertion tube.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: The bearing cage of this application adopts a unique locking and safety component structure, making the assembly and disassembly of the cage simple and convenient.

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, an easily detachable bearing cage includes a first retaining half-cage 1 and a second retaining half-cage 2. The first retaining half-cage includes a first annular frame 11 and a first arc-shaped baffle 12. The first arc-shaped baffle 12 is evenly distributed along one side of the first annular frame 11 in the circumferential direction and is integrally formed with the first annular frame 11. A plurality of insertion tubes 3 are evenly installed on the inner surface of the first annular frame 11, and the insertion tubes 3 are integrally formed with the first annular frame 11. The second retaining half-cage 2 is sleeved on the insertion tubes 3 and fixed to the insertion tubes 3 by locking members 4. A safety member 5 is also inserted and installed on the locking member 4. The integral formation of the first annular frame 11 and the first arc-shaped baffle 12 of the first retaining half-cage 1 ensures the stability and integrity of the structure, enabling better guidance and positioning of the rolling elements. The integral formation of the insertion tubes 3 with the first annular frame 11 provides a reliable connection basis for the installation of the second retaining half-cage 2. The retaining half-cage 2 is fixed to the insertion tube 3 via the locking element 4, facilitating the assembly and disassembly of the cage without the need for complex tools and operations, thus improving work efficiency. Simultaneously, a safety element 5 is inserted and installed on the locking element 4, further enhancing the reliability of the connection and preventing the locking element 4 from loosening during use, ensuring the normal operation of the bearing cage. Retaining half-cage 1 and retaining half-cage 2 can be made of high-strength engineering plastics or metal materials, such as polyamide (PA) or aluminum alloy. Engineering plastics have advantages such as light weight, corrosion resistance, and good self-lubrication, making them suitable for applications with high weight and noise requirements. Aluminum alloys have high strength and good thermal conductivity, making them suitable for high-speed, heavy-load working environments. The insertion tube 3 can be made of the same material as retaining half-cage 1 to ensure the connection strength and stability between them. The locking element 4 and safety element 5 can be made of metal materials with a certain degree of elasticity and strength, such as spring steel, to ensure their elasticity and reliability.

[0028] Reference Figure 4As shown, the second half-frame includes a second annular frame 21 and a second arc-shaped baffle 22. The second arc-shaped baffle 22 is evenly arranged on one side of the second annular frame 21 along the circumferential direction, and the second arc-shaped baffle 22 is integrally formed with the second annular frame 21. The specific structure of the second half-frame 2 is clarified, with the second annular frame 21 and the second arc-shaped baffle 22 integrally formed. This structural design gives the second half-frame 2 good strength and rigidity, enabling it to cooperate with the first half-frame 1 to uniformly distribute and guide the rolling elements, ensuring stable movement of the rolling elements within the bearing, reducing friction and wear, and improving the bearing's service life. The second annular frame 21 is provided with several insertion holes 211 for inserting the insertion tube 3. The insertion holes 211 are evenly arranged along the circumferential direction of the second annular frame 21. The insertion holes 211 on the second annular frame 21 provide precise positioning and guidance for the installation of the insertion tube 3, allowing the second half-frame 2 to be accurately fitted onto the insertion tube 3, ensuring the accuracy of the cage assembly. The insertion holes 211, which are evenly arranged along the circumference, make the connection between the second half-frame 2 and the first half-frame 1 more uniform and stable, avoiding excessive local stress caused by uneven connection and improving the overall performance of the bearing cage.

[0029] Reference Figure 6 As shown, the locking component 4 includes an outer plate 41 and elastic claws 42. There are two sets of elastic claws 42, symmetrically mounted on one side of the outer plate 41. The elastic claws 42 and the outer plate 41 are integrally formed. The locking component 4 utilizes the structure of the outer plate 41 and elastic claws 42. The elastic characteristics of the elastic claws 42 allow them to deform automatically during installation, facilitating insertion into the connector 3. After insertion, the elastic restoring force ensures a tight connection with the connector 3. The outer plate 41 provides support and fixation for the elastic claws 42, ensuring the overall stability of the locking component 4. This structural design makes the assembly and disassembly of the cage more convenient; connection and separation can be completed simply by operating the elastic claws 42. The elastic pawl 42 includes a strip plate 421, a triangular pawl 422, and an arc-shaped wrench 423. The triangular pawl 422 is located at one end of the strip plate 421, and the arc-shaped wrench 423 is mounted on the inner side of the triangular pawl 422. The strip plate 421, triangular pawl 422, and arc-shaped wrench 423 are integrally formed. The triangular pawl 422 can cooperate with the guide groove 31 in the connector 3 to achieve a reliable connection between the locking member 4 and the connector 3, preventing the locking member 4 from coming out during use. The arc-shaped wrench 423 facilitates the operation of the elastic pawl 42 by the operator. By turning the arc-shaped wrench 423, the elastic pawl 42 can be deformed, thereby achieving the locking and unlocking functions and improving the convenience of operation.

[0030] Reference Figure 5As shown, safety component 5 includes an outer cover 51 and a I-beam frame 52. The I-beam frame 52 is fixedly installed on the inner side of the outer cover 51 and is inserted between two sets of elastic claws 42. The structure of the outer cover 51 and the I-beam frame 52, with the I-beam frame 52 inserted between the two sets of elastic claws 42, prevents the elastic claws 42 from accidentally deforming or loosening during use. The outer cover 51 provides protection, preventing dust, debris, etc., from entering the locking component 4 and affecting its normal operation. The safety component 5 further enhances the reliability and stability of the locking component 4 and improves the safety of the bearing cage.

[0031] Reference Figure 3 As shown, two sets of guide grooves 31 are symmetrically provided on the inner side of the insertion tube 3 for the installation of the triangular locking block 422. The guide grooves 31 on the inner side of the insertion tube 3 provide precise guidance and positioning for the installation of the triangular locking block 422, allowing the triangular locking block 422 to be smoothly inserted into the insertion tube 3 and tightly fitted with the insertion tube 3. The symmetrical arrangement of the guide grooves 31 ensures the balanced and stable installation of the locking member 4 in the insertion tube 3, further improving the reliability of the cage connection.

[0032] In this embodiment, during actual assembly, the insertion hole 211 of the retaining half-frame 2 is aligned with the insertion tube 3 of the retaining half-frame 1, and the retaining half-frame 2 is slowly fitted onto the insertion tube. The elastic claw 42 of the locking member 4 is aligned with the guide groove 31 of the insertion tube 3, and the locking member is forcefully inserted into the insertion tube. During the insertion process, the elastic claw will automatically deform, and the triangular block 422 will slide along the guide groove. When the triangular block reaches the appropriate position of the guide groove, the elastic claw will regain its elasticity, and the triangular block will fit tightly with the guide groove, realizing the connection between the locking member and the insertion tube. The I-beam 52 of the safety member 5 is aligned with the gap between the two sets of elastic claws 42, and the safety member is forcefully inserted, so that the I-beam is inserted between the two sets of elastic claws, completing the installation of the safety member.

[0033] During disassembly, first pull the safety component 5 from the locking component 4 to release the restriction on the elastic claw 42. Use your hand to turn the arc-shaped wrench 423 on the elastic claw 42 to deform the claw, causing the triangular block 422 to disengage from the guide groove 31. Pull the locking component 4 from the insertion tube 3. Remove the retaining half 2 from the insertion tube 3 to complete the disassembly of the retainer.

[0034] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
