Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a plug-in type easily detachable combined bearing forging. Background Technology

[0002] Bearing forgings refer to ring-shaped bearing parts formed through forging processes. Bearings play a crucial role in mechanical equipment, primarily supporting rotating mechanical parts, reducing the coefficient of friction during movement, and ensuring operational accuracy.

[0003] When bearings are assembled and used, cages are installed on the inner and outer rings to secure the internal balls. The two cages are usually fixed together by small screws. Disassembly requires the use of tools to remove them one by one, which is very inconvenient. Moreover, the bearing balls are directly exposed to the outside, which can cause dust to enter the bearing and cause it to seize. In order to address this technical problem, this application proposes a plug-in type easy-to-disassemble combined bearing forging. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plug-in type easily detachable combined bearing forging. Two cages are snapped onto the outer wall of the balls, and then the two cages are pressed down to engage the fixing post on the lower cage with the fixing hole on the upper cage, thus completing the installation. Disassembly is achieved by simply pulling the handles on the two cages to separate them from the bearing, eliminating the need for tools to remove the screws sequentially, greatly improving the speed of bearing installation and disassembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A plug-in type easily detachable combined bearing forging includes an outer ring, a plurality of balls arranged on the inner wall of the outer ring, an inner ring arranged on the inner wall of the balls, a retainer arranged at both the upper and lower ends of the balls, handles fixedly connected to the front and rear sides of the opposite end of the retainer, a plurality of fixing holes opened at the bottom end of the upper retainer, a plurality of fixing posts fixedly connected to the top end of the lower retainer, and dustproof components arranged at both the upper and lower ends of the outer ring.

[0007] Furthermore, the dustproof component includes multiple guide grooves located at both the upper and lower ends of the outer ring, and positioning blocks are engaged with the inner walls of the guide grooves. A cover plate is fixedly connected to one end of each positioning block.

[0008] Furthermore, the inner walls at both ends of the cover plate are provided with sliding grooves, and sliders are slidably connected to the inner walls of the sliding grooves. A limit block is fixedly connected to one end of each slider.

[0009] Furthermore, the inner walls at both ends of the outer ring are provided with limiting grooves on the upper and lower sides, and the size of the limiting grooves matches the limiting block.

[0010] This utility model has the following beneficial effects:

[0011] 1. In this utility model, the two cages are snapped onto the outer wall of the ball, and then the two cages are pressed so that the fixing post on the lower cage is snapped into the fixing hole of the upper cage to complete the installation. When disassembling, the two cages can be separated and removed from the bearing by simply pulling the handles on the two cages. There is no need to use tools to remove the screws one by one, which greatly improves the speed of bearing installation and disassembly.

[0012] 2. In this utility model, the positioning block on the cover plate is aligned with the guide groove on the outer ring, so that the cover plate is inserted into the groove between the outer ring and the inner ring. Then, the limiting block is pushed outward to insert it into the limiting groove to complete the installation of the cover plate. This allows the cover plate to cover the ball, preventing external dust from entering and causing the bearing to seize. The operation is convenient. Attached Figure Description

[0020] 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.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 An embodiment of this utility model is provided: a plug-in type easily detachable combined bearing forging, including an outer ring 1, a plurality of balls 9 are provided on the inner wall of the outer ring 1, an inner ring 3 is provided on the inner wall of the balls 9, a retainer 7 is provided at both the upper and lower ends of the balls 9, a handle 12 is fixedly connected to the front and rear sides of the opposite end of the retainer 7, a plurality of fixing holes 13 are opened at the bottom of the upper retainer 7, and a plurality of fixing posts 14 are fixedly connected to the top of the lower retainer 7;

[0022] Specifically, the fixing post 14 is made of elastic rubber and has an interference fit with the fixing hole 13. When the lower retainer 7 is pushed, the fixing post 14 will be inserted into the fixing hole 13 of the upper retainer 7 and undergo a certain deformation, thereby realizing the connection between the two retainers 7. When disassembling, the two retainers 7 can be separated from the bearing by simply pulling the handle 12 on the two retainers 7 to apply a certain pulling force. There is no need to use tools to remove the screws one by one, which greatly improves the speed of bearing installation and disassembly.

[0023] Reference Figure 1 , Figure 2 and Figure 4 Dustproof components are provided at both the top and bottom of the outer ring 1. The dustproof components include multiple guide grooves 6 located at both the top and bottom of the outer ring 1. Positioning blocks 4 are snapped into the inner walls of the guide grooves 6. A cover plate 2 is fixedly connected to one end of the positioning block 4. Sliding grooves 11 are provided on the inner walls of both the front and rear ends of the cover plate 2. Sliding sliders 10 are slidably connected to the inner walls of the sliding grooves 11. A limit block 5 is fixedly connected to one end of the slider 10. Limit grooves 8 are provided on both the top and bottom sides of the inner walls of both the front and rear ends of the outer ring 1. The size of the limit grooves 8 matches that of the limit blocks 5.

[0024] Specifically, the guide groove 6, in conjunction with the positioning block 4, can quickly guide the limiting block 5 during installation, aligning it with the limiting groove 8. The size of the sliding groove 11 inside the cover plate 2 gradually decreases from near the inner side of the cover plate 2 to near the outer side. The slider 10 is made of elastic rubber, so that when the operator pushes the limiting block 5 into the limiting groove 8, the slider 10 slides inside the sliding groove 11 and gradually deforms, forming an interference fit with the sliding groove 11, increasing the friction between the slider 10 and the sliding groove 11. This ensures that after the limiting block 5 is fully inserted into the limiting groove 8, it will not slide freely on the cover plate 2, but requires the operator to manually apply a certain pushing force to detach it from the limiting groove 8, preventing the cover plate 2 from falling off the outer ring 1.

[0025] Working principle: In actual use, the operator only needs to push the limiting blocks 5 on both sides of the cover plate 2 to disengage them from the limiting grooves 8 to release the limiting, thereby removing the cover plate 2 from the outer ring 1. Then, pull the handles 12 on the retainer 7 to both sides to disengage the fixing posts 14 from the fixing holes 13, thus removing the retainer 7. At this time, push the ball bearing 9 to one side inside the outer ring 1 and then press the inner ring 3 to the other side to remove the ball bearing 9 and the inner ring 3 from the outer ring 1 for maintenance and replacement. The operation is convenient. After maintenance, the inner ring 3 and the ball bearing 9 are snapped back into the outer ring 1, and then adjusted. The distance between each ball 9 is determined by inserting two retainers 7 onto the outer wall of the ball 9 to restrict its position. Then, the two retainers 7 are pressed down so that the fixing post 14 on the lower retainer 7 is inserted into the fixing hole 13 of the upper retainer 7 to complete the installation. Next, the positioning block 4 on the cover plate 2 is aligned with the guide groove 6 on the outer ring 1 so that the cover plate 2 is inserted into the groove between the outer ring 1 and the inner ring 3. Then, the limiting block 5 is pushed outward so that it is inserted into the limiting groove 8 to complete the installation of the cover plate 2. This allows the cover plate 2 to cover the ball 9 and prevent external dust from entering and causing the bearing to seize.

[0026] 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.
