And the two cages need to be fixed through a riveting process. In order to simplify this step and further improve the assembly efficiency of the deep groove ball bearing, a combined deep groove ball bearing is provided. Summary of the Utility Model

[0027] Please refer to Figures 1 to 4 , in the embodiments of the present utility model, a combined deep groove ball bearing includes a deep groove ball bearing 1 composed of an outer ring 101, an inner ring 102, and steel balls 103. The outer ring 101 and the inner ring 102 are distributed in sequence from outside to inside, and multiple steel balls 103 are annularly distributed between the outer ring 101 and the inner ring 102. A cage assembly 2 is arranged on the outer side of the steel balls 103, and the cage assembly 2 is used to limit the relative positions of the multiple steel balls 103;

[0028] The cage assembly 2 includes a limiting unit, a clamping unit, and an anti-loosening unit. The limiting unit is used to clamp and limit the multiple steel balls 103, the clamping unit is used to realize the quick installation and fixation of the limiting unit, and the anti-loosening unit is used to reinforce the splicing of the limiting unit to prevent the clamping unit from loosening;

[0029] The limiting unit includes a first annular frame 201, a second annular frame 202, and a semi-spherical pocket 203;

[0030] The first annular frame 201 and the second annular frame 202 are symmetrically distributed on both sides of the steel balls 103. There are two groups of semi-spherical pockets 203, and the two groups of semi-spherical pockets 203 are symmetrically formed on the first annular frame 201 and the second annular frame 202. The number of semi-spherical pockets 203 in the two groups of semi-spherical pockets 203 matches the number of steel balls 103. The steel balls 103 are wrapped and limited by the fitting of the two symmetrically distributed semi-spherical pockets 203;

[0031] The clamping unit includes a deformation hole 205, a 7-shaped buckle 206, and a through hole 207. The deformation hole 205 is opened on one side of the first annular frame 201 and penetrates through the other side of the first annular frame 201. There are multiple deformation holes 205, and the multiple deformation holes 205 are evenly distributed in a circular shape on the first annular frame 201. The 7-shaped buckle 206 is fixed inside the deformation hole 205 and penetrates through the deformation hole 205 to the other side of the first annular frame 201. The through hole 207 is opened on one side of the second annular frame 202 and penetrates through to the other side of the second annular frame 202. The first annular frame 201 and the second annular frame 202 are connected and fixed by the 7-shaped buckle 206 penetrating through the through hole 207 and being clamped to the other side of the second annular frame 202;

[0032] The anti-loosening unit includes a positioning post 204. The positioning post 204 is fixed on the side of the first annular frame 201 close to the second annular frame 202. There are multiple positioning posts 204 evenly arranged in the circumferential direction and two in a group. Each group of positioning posts 204 is symmetrically distributed with the deformation hole 205 as the center;

[0033] There are multiple through holes 207 and three in a group. The through hole 207 in the middle of a group of through holes 207 is aligned with the 7-shaped buckle 206, and the other two through holes 207 are aligned with the positioning posts 204. The rotation direction of the first annular frame 201 and the second annular frame 202 is limited by the positioning posts 204 being inserted into the through holes 207, so as to prevent the 7-shaped buckle 206 from being deformed due to the first annular frame 201 and the second annular frame 202 shifting along the rotation direction.

[0034] In this embodiment: After the steel ball 103 is installed between the outer ring 101 and the inner ring 102, the position of the steel ball 103 can be limited by the cage assembly 2, and the operation steps are as follows:

[0035] First, install the first annular frame 201 on one side of the steel ball 103, so that each steel ball 103 is respectively located inside the semi-spherical pockets 203 on the first annular frame 201;

[0036] Then, install the second annular frame 202 on the other side of the steel ball 103, and make the semi-spherical pockets 203 on the second annular frame 202 sleeved and wrapped outside each steel ball 103, so as to realize the limiting and fixing of the relative positions of the multiple steel balls 103;

[0037] During the installation of the second annular frame 202, its L-shaped buckle 206 will be inserted into the inner side of the corresponding through hole 207. At this time, the end of the L-shaped buckle 206 will be deformed and contracted under force. When the end passes through the through hole 207, the L-shaped buckle 206 will reset under its own elastic force, and the end will be clamped outside the second annular frame 202. In this way, the fixation of the second annular frame 202 and the first annular frame 201 is realized, and then the overall assembly of the bearing is completed. Compared with the traditional assembly mechanism, the riveting and fixing process is omitted, and the assembly efficiency of the deep groove ball bearing 1 is further improved;

[0038] In addition, it should be noted that when the L-shaped buckle 206 is clamped with the through hole 207, the positioning post 204 is synchronously clamped into the corresponding through hole 207 (the outer diameter of the positioning post 204 matches the inner diameter of the through hole 207). Through the positioning post 204, the relative positions of the first annular frame 201 and the second annular frame 202 in the rotation direction can be limited, avoiding the wrong offset of the first annular frame 201 and the second annular frame 202 along the rotation direction. In this way, the state of the L-shaped buckle 206 is ensured to be stable, and then the connection stability of the first annular frame 201 and the second annular frame 202 is improved.

[0039] Please refer specifically to Figures 1 to 4 , a plurality of L-shaped buckles 206 are arranged inside a single deformation hole 205, and the plurality of L-shaped buckles 206 are evenly distributed in a circle with the center of the deformation hole 205 as the center.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
