Description

Technical Field

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

[0002] Rolling bearings are one of the most widely used support structures in machinery. They are mainly used to support rotating shafts and reduce friction during movement. Compared with sliding bearings, rolling bearings have advantages such as low friction, high efficiency, easy maintenance, and high standardization. Rolling bearings consist of an inner ring, an outer ring, rolling elements, and a cage.

[0003] The existing publication number CN208734731U, entitled "A Bearing Cage," includes a first cage, a second cage at the front end of the first cage, a third cage on one side of the first cage, and a fourth cage at the front end of the third cage. The outer surface of the fourth cage has a fourth ball groove, the outer surface of the first cage has a first ball groove, the outer surface of the second cage has a second ball groove, and the outer surface of the third cage has a third ball groove. This utility model, through a series of structural features, facilitates the disassembly and assembly of the balls during use. It also allows for the convenient recycling of the remaining three cages when one cage is damaged, improving economic efficiency. Furthermore, it effectively adds lubricating oil to the balls inside the bearing, preventing rust between the balls and the bearing cage.

[0004] However, the aforementioned bearing cage is assembled by setting up three modules, and the damaged part is disassembled and replaced later. However, the part of the bearing cage that wears out faster during use is the pocket. If the bearing cage pocket wears out, the cage will be discarded, resulting in a decrease in the resource utilization rate of the cage. Utility Model Content

[0022] like Figures 1 to 4 As shown, a bearing cage for a rolling bearing includes a retainer 1 and a quick-release member 2. The retainer 1 includes a connecting bridge 11, with guide surfaces 12 on both ends of the connecting bridge 11. Multiple horizontally evenly perforated assembly slots 14 are provided on the connecting bridge 11. Each of the multiple assembly slots 14 on the connecting bridge 11 can be detachably assembled with a quick-release member 2. The quick-release member 2 includes a pocket cylinder 21, with multiple horizontally evenly fixed protrusions on its outer wall. These protrusions slide into the assembly slots 14 on the connecting bridge 11. 4. Assembly slots 15 are provided on both sides. Hole seats 22 are horizontally fixed on both sides of the outer wall of the pocket cylinder 21. The hole seats 22 of the pocket cylinder 21 are inserted into the assembly slots 15. In order to make full use of the connecting bridge 11 of the retainer 1, the quick-release part 2 can be detached and assembled in the assembly slots 14 that are evenly and horizontally opened on the connecting bridge 11. The rolling elements of the bearing are rotatably installed in the pocket cylinder 21 of the quick-release part 2. During use, the pocket cylinder 21 is worn by the friction of the rolling elements. When the pocket cylinder 21 is replaced in the later stage, it is not necessary to directly discard the connecting bridge 11, thus improving the resource utilization rate.

[0023] In one embodiment, such as Figure 3 and 4As shown, two positioning posts 16 are vertically arranged on both the upper and lower sides of the assembly channel 15. One end of the two positioning posts 16 is inserted into the hole seat 22 of the pocket cylinder 21, and the other end of the two positioning posts 16 is vertically fixed to the elastic frame 17. The other end of the elastic frame 17 is fixed to the inner wall of the assembly channel 15. The pocket cylinder 21 is used to limit the insertion into the assembly slot 14 of the connecting bridge 11. Pulling the positioning posts 16 in the assembly channel 15 squeezes the elastic frame 17 to deform. Then, the hole seats 22 on both sides of the pocket cylinder 21 are inserted into the interior of the assembly channel 15. When the positioning posts 16 are released, under the deformation force of the elastic frame 17, the positioning posts 16 are pushed into the hole seats 22 of the pocket cylinder 21, and the quick-release part 2 is quickly installed on the connecting bridge 11.

[0024] In one embodiment, such as Figure 4 As shown, an oil reservoir ring 23 is fixed inside the pocket cylinder 21, and an oil groove 231 is provided on the inner wall of the oil reservoir ring 23. A cloth tube 24 is filled in the oil groove 231 of the oil reservoir ring 23. The oil reservoir ring 23 is made of silicon carbide, and the cloth tube 24 is made of nylon. During use, the rolling element is placed inside the oil reservoir ring 23 inside the pocket cylinder 21. The oil reservoir ring 23 is made of silicon carbide, and the oil groove 231 inside the oil reservoir ring 23 is filled with lubricating oil. The lubricating oil is applied to the outer surface of the rolling element through the cloth tube 24. The oil reservoir ring 23 made of silicon carbide and the cloth tube 24 made of nylon increase the overall wear resistance of the quick-release part 2.

[0025] In one embodiment, such as Figure 3 As shown, guide grooves 13 are provided on both the inner and outer arc-shaped end faces of the guide surface 12. The part of the guide groove 13 that contacts the inner or outer ring of the bearing is used to guide the movement direction of the cage.

[0026] In this embodiment, in order to make full use of the connecting bridge 11 of the retainer 1, the quick-release component 2 is detachably assembled in the assembly slot 14 that is uniformly and horizontally opened on the connecting bridge 11. The pocket cylinder 21 is limited and inserted into the assembly slot 14 of the connecting bridge 11. The positioning post 16 in the assembly through slot 15 is pulled to compress the elastic frame 17 and deform it. Then, the two side holes 22 of the pocket cylinder 21 are inserted into the interior of the assembly through slot 15. The positioning post 16 is released and pushed into the hole seat 22 of the pocket cylinder 21 under the deformation force of the elastic frame 17. The quick-release component 2 is quickly and limitedly installed on the connecting bridge 11. The rolling elements of the bearing are rotatably installed in the pocket cylinder 21 of the quick-release component 2. During use, the pocket cylinder 21 is worn by the rotation friction of the rolling elements. The pocket cylinder 21 is replaced later without directly discarding the connecting bridge 11.

[0027] The above are preferred embodiments of the present utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present 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 the present utility model shall fall within the protection scope of the present utility model.
