[0021] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] Reference Figures 1-5 A deep groove ball bearing with a separable outer ring includes a first outer ring 1. A connecting protrusion 8 is provided at the end of the first outer ring 1. A second outer ring 2 is fitted around the connecting protrusion 8. A connecting groove 9 is formed at the end of the second outer ring 2, and the connecting protrusion 8 is located inside the connecting groove 9. A first sliding groove 11 and a mounting groove 14 are formed at the top of the second outer ring 2. A second sliding groove 16 is formed inside the mounting groove 14. A second slider 17 is slidably connected inside the second sliding groove 16. A limit post 18 is fixedly connected inside the second slider 17. Both the top and bottom of the protrusion 8 are provided with slots 10, and the end of the limiting post 18 away from the second slider 17 is engaged with the inside of the slot 10. The inner sidewall of the mounting groove 14 is fixedly connected to a limiting ring 15, and the inside of the limiting ring 15 is provided with a connecting hole 19. A connecting rope 20 is movably connected inside the connecting hole 19. One end of the connecting rope 20 is fixedly connected to the top of the limiting post 18, and the end of the connecting rope 20 away from the limiting post 18 is fixedly connected to a first slider 13. The first slider 13 is slidably connected to the inside of the first slide groove 11. When it is necessary to disassemble the first outer ring 1 and the second outer ring 2, the first slider 13 is pushed, so that the first slider 13 drives the limiting post 18 and the second slider 17 to slide inside the second slide groove 16 through the connecting rope 20 during the sliding process. This facilitates the separation of the limiting post 18 from the slot 10, and enables the quick disassembly of the first outer ring 1 and the second outer ring 2.
[0023] The inner wall of the first slide groove 11 is fixedly connected to two fixed posts 12, which are symmetrically distributed. The first slider 13 is slidably connected to the outside of the fixed posts 12. The first slider 13 slides outside the fixed posts 12 due to the constraint of the fixed posts 12.
[0024] The bottom of the limiting ring 15 is fixedly connected with a compression spring 21, and the bottom end of the compression spring 21 is in abutment with the top of the limiting column 18. When the first sliding block 13 drives the limiting column 18 to move through the connecting rope 20, the compression spring 21 is compressed, and when the limiting column 18 is engaged with the inner part of the clamping groove 10, the limiting column 18 is tightly engaged with the inner part of the clamping groove 10 under the pushing of the reaction force of the compression spring 21, so that the stability of the connection between the first outer ring 1 and the second outer ring 2 is enhanced.
[0025] The inner part of the first outer ring 1 and the second outer ring 2 is provided with a first limiting groove 4, and the inner part of the first limiting groove 4 is movably connected with a rolling ball 7. The rolling ball 7 is used to reduce the friction between the first outer ring 1 and the second outer ring 2.
[0026] The end of the rolling ball 7 away from the first outer ring 1 is movably connected with an inner ring 3, the circumferential surface of the inner ring 3 is provided with a second limiting groove 5, and the rolling ball 7 is movably connected with the inner side wall of the second limiting groove 5. The rolling ball 7 is located between the outer ring and the inner ring 3.
[0027] The number of the rolling ball 7 is multiple, and the rolling ball 7 is distributed in a ring shape, and the outer part of the multiple rolling ball 7 is movably connected with a connecting sleeve 6. The multiple rolling ball 7 is connected together by the connecting sleeve 6, so that the installation is facilitated.
[0028] Working principle: when the first outer ring 1 and the second outer ring 2 need to be disassembled, the first sliding block 13 is pushed, so that the first sliding block 13 drives the limiting column 18 and the second sliding block 17 to slide in the second sliding groove 16 through the connecting rope 20 in the sliding process, so that the limiting column 18 is separated from the clamping groove 10, the first outer ring 1 and the second outer ring 2 can be quickly disassembled, and when the limiting column 18 moves, the compression spring 21 is compressed, and the limiting column 18 is tightly engaged with the inner part of the clamping groove 10 under the pushing of the reaction force of the compression spring 21, so that the stability of the connection between the first outer ring 1 and the second outer ring 2 is enhanced, and after the first outer ring 1 and the second outer ring 2 are disassembled and the connecting sleeve 6 is disassembled, the multiple rolling ball 7 can be taken down for replacement.
[0029] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
