[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.
[0003] Existing multi-row ball bearings are assembled and fixed together to form a multi-row ball bearing. However, the above assembly and fixing method usually involves connecting them in series with connecting rods and then fixing them with screws. This means that when repairing a single bearing, not only does the whole assembly need to be disassembled, but the screws also need to be frequently removed and reinstalled, which affects the maintenance efficiency and results in low performance. Therefore, there is an urgent need for a multi-row ball bearing to solve the above problems. Utility Model Content

[0007] This utility model is achieved through the following technical solution: This utility model proposes a multi-row combined ball bearing, including an outer ring arranged in series. A connecting cavity is formed on one side wall of the outer ring. A connecting post is fixed to the end of the outer ring away from the connecting cavity. A locking groove is formed on the outer side wall of the outer ring. A flexible telescopic rod is fixed in the locking groove. A spring is sleeved on the outer side of the flexible telescopic rod. A lever is fixed on the movable end of the flexible telescopic rod. A limit rod is fixed on one side wall of the lever. A limit hole is formed on the connecting post.

[0009] By adopting the above technical solution, the connection cavity and the connection column can be combined to achieve the initial assembly of a single bearing.
[0010] Furthermore, the locking groove is formed on the outer side wall of the outer ring, the fixing part of the flexible telescopic rod is connected to the locking groove by screws, and the spring is welded to the flexible telescopic rod.
[0011] By adopting the above technical solution, the flexible telescopic rod combined with the spring can enable the toggle block to automatically reset.
[0012] Furthermore, the lever is fixed to the movable end of the flexible telescopic rod by screws, and the lever is slidably connected to the locking groove.
[0013] By adopting the above technical solution, an external force is applied to the toggle block, causing it to move under the action of the flexible telescopic rod and the spring.
[0014] Furthermore, the limiting rod is welded to one side wall of the lever block, the limiting rod has a certain curvature, the limiting hole is formed on the connecting column, the limiting hole is inserted into the limiting rod, and the limiting hole has a certain curvature.
[0015] By adopting the above technical solution, the pusher block drives the limiting rod to move, thereby separating it from the limiting hole, which can release the fixing of the connecting column and facilitate the disassembly of the assembled bearing.
[0016] Furthermore, the guide groove is formed on the locking groove, and the guide block is slidably connected to the guide groove.
[0017] By adopting the above technical solution, the guide block and the guide groove limit and guide the movement of the push block.

[0020] (III) Beneficial Effects
[0021] Compared with the prior art, this utility model has the following advantages:
[0022] To address the problem that existing multi-row ball bearing systems rely on assembling and fixing multiple ball bearings together, often using connecting rods and screws for further fixation, necessitates disassembly of the entire assembly for individual bearing maintenance, leading to inefficiency and low performance. This invention addresses this issue by incorporating a flexible telescopic rod, spring, lever, limiting rod, and limiting hole. When a bearing needs maintenance, applying external force through the lever separates the limiting rod from the limiting hole, compresses the flexible telescopic rod and spring, and releases the assembly fixation. This allows for independent disassembly of the individual bearing. During installation, repeating this process releases external force, and the spring and flexible telescopic rod's rebound force automatically resets the limiting rod, securing the bearing. This method is convenient for operators, highly efficient in assembly and disassembly, and effectively improves the device's performance. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages 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.
[0029] like Figures 1-3As shown, a multi-row combined ball bearing 3 in this embodiment includes an outer ring 1 arranged in series. A connecting cavity 11 is formed on one side wall of the outer ring 1. A connecting post 12 is fixed to the end of the outer ring 1 away from the connecting cavity 11. The connection cavity 11 and the connecting post 12 can be combined to achieve the initial assembly of a single bearing. A locking groove 4 is formed on the outer side wall of the outer ring 1. A flexible telescopic rod 7 is fixed in the locking groove 4. A spring 8 is sleeved on the outside of the flexible telescopic rod 7. The combination of the flexible telescopic rod 7 and the spring 8 can cause the lever 5 to automatically reset. The movement of the flexible telescopic rod 7... A lever 5 is fixed at one end. An external force is applied to the lever 5, causing it to move under the action of the flexible telescopic rod 7 and the spring 8. A limit rod 6 is fixed on one side wall of the lever 5. A limit hole 13 is opened on the connecting column 12. The lever 5 drives the limit rod 6 to move, thereby separating it from the limit hole 13. The fixing of the connecting column 12 can be released, making it easier to disassemble the assembled bearing. A guide groove 9 is opened on one side wall of the locking groove 4. A guide block 10 is fixed on one side wall of the lever 5. The guide block 10 and the guide groove 9 limit and guide the movement of the lever 5.
[0030] like Figures 1-3 As shown, in this embodiment, the connecting cavity 11 and the connecting post 12 are both formed on the outer ring 1. The specifications of the connecting cavity 11 and the connecting post 12 are matched. The connecting post 12 is inserted into the connecting cavity 11. The locking groove 4 is formed on the outer side wall of the outer ring 1. The fixed part of the flexible telescopic rod 7 is connected to the locking groove 4 by screws. The spring 8 is welded to the flexible telescopic rod 7. The lever 5 is fixed to the movable end of the flexible telescopic rod 7 by screws. The lever 5 is slidably connected to the locking groove 4. The limiting rod 6 is welded to one side wall of the lever 5. The limiting rod 6 has a certain curvature. The limiting hole 13 is formed on the connecting post 12. The limiting hole 13 is inserted into the limiting rod 6. The limiting hole 13 has a certain curvature.
[0031] like Figures 1-3 As shown, in this embodiment, the guide groove 9 is formed on the locking groove 4, the guide block 10 is slidably connected to the guide groove 9, the outer ring 1 is provided with an inner ring 2, and multiple sets of balls 3 are arranged in an array on the outer ring 1 and the inner ring 2. The outer ring 1, the balls 3 and the inner ring 2 can constitute a bearing.
[0032] The specific implementation process of this embodiment is as follows: During use, the limiting rod 6 and the limiting hole 13 are combined to assemble and fix a single bearing, ensuring its performance. When a bearing needs to be repaired, external force is applied by the lever 5 to cause the limiting rod 6 to separate from the limiting hole 13 and the flexible telescopic rod 7 and spring 8 to compress, thus releasing the assembly fixation. At this time, the single bearing can be disassembled independently. After maintenance, during installation, the above operation is repeated to release the external force. The limiting rod 6 can be automatically reset by relying on the rebound force of the spring 8 and the flexible telescopic rod 7, thus assembling and fixing the bearing. This method is convenient for operators and has high disassembly and assembly efficiency, effectively improving the performance of the device.
