Description

A type of bearing Technical Field

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

[0002] A ball bearing is a mechanical component that achieves efficient transmission through rolling friction. Its core structure consists of an inner ring, an outer ring, rolling elements, and a cage.

[0003] In mechanical transmission systems, the traditional connection between bearings and products typically employs a spline-keyway fit structure. Specifically, an external spline is machined on the product shaft, while a corresponding internal keyway is formed on the bearing's inner ring. During assembly, an interference fit precisely inserts the spline on the shaft into the keyway in the bearing's inner ring, achieving torque transmission and radial positioning. However, when the system experiences frequent start-stop cycles or bears impact loads, fretting wear occurs on the spline meshing surfaces, leading to abnormal vibration and noise. In such cases, the entire bearing needs to be replaced, increasing resource waste. Therefore, this solution proposes a bearing to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a bearing to solve the problems mentioned in the background art.

[0024] 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.

[0025] This utility model provides the following as shown in Figures 1-4:

[0026] Example 1: A bearing, comprising:

[0027] Inner circle 1;

[0028] Outer ring 2, which is fitted onto the outer wall of inner ring 1;

[0029] Steel ball 3 is located on the side opposite to the inner ring 1 and the outer ring 2. A limiting component 4 is provided on one side of the inner ring 1.

[0030] The split ring 6 is interlocked in the middle of the inner ring 1, and a keyway 601 is provided on the inner wall of the back of the split ring 6.

[0031] Mounting component 7 is located at the connection between inner ring 1 and split ring 6, and is used to fix the position of split ring 6.

[0032] The limiting component 4 includes a retainer 401 symmetrically fitted on the top and bottom of the steel ball 3. A rivet 402 is provided in the middle of the retainer 401. A sealing ring 5 is provided at the connection between the inner ring 1 and the outer ring 2. The sealing ring 5 is used to block dust.

[0033] It should be noted that the steel ball 3, as a rolling element, rolls between the two arc-shaped raceways of the inner ring 1 and the outer ring, converting sliding friction into rolling friction. This reduces frictional resistance and improves transmission efficiency. The arc-shaped grooves on the inner ring 1 and the outer ring 2 are precision-machined to ensure a match with the contact surface of the steel ball 3, resulting in uniform load distribution, reducing stress concentration, and guiding the steel ball 3 to roll smoothly. The cage 401 is a key component inside the bearing, used to evenly separate and guide the steel ball 3, preventing them from colliding or rubbing against each other, and ensuring that the rolling elements move smoothly and orderly within the raceways of the inner and outer rings 2. The main function of the sealing ring 5 is to prevent external contaminants from entering the bearing and reduce the leakage of internal lubricant, thereby extending the bearing life and maintaining stable operation. The original inner groove ring is split into the existing inner ring 1 and the split ring 6. The inner ring 1 and the split ring 6 are connected by the mounting assembly 7. When the keyway 601 on the bearing is worn, the split ring 6 that matches the connecting part is first taken out. The split ring 6 is then replaced from the middle of the inner ring 1 by the mounting assembly 7, avoiding the need to replace the entire bearing and thus reducing the waste of resources.

[0034] Example 2: Mounting component 7 is applied to a bearing as described in Example 1;

[0035] Specifically, the mounting component 7 includes a compression groove 701 on one side of the split ring 6, a pressing block 705 inserted inside the compression groove 701, a storage groove 706 on one side of the inner ring 1, the pressing block 705 inserted inside the storage groove 706, a rotating groove 704 on one side of the pressing block 705, a rotating block 703 inserted inside the rotating groove 704, a threaded rod 711 fixedly connected to one side of the rotating block 703, and a threaded rod 711 fixedly connected to one side of the storage groove 706. The inner wall of the rotating block 703 has a threaded groove 710, and the threaded rod 711 is threadedly connected to the inside of the threaded groove 710. The other side of the rotating block 703 has a hexagonal groove 702. The inner wall of one side of the rotating groove 704 has a through hole 707, and the threaded rod 711 is inserted into the inside of the through hole 707. A limiting ring 709 is sleeved in the middle of the threaded rod 711. The other side of the pressing block 705 has a limiting groove 708, and the limiting ring 709 is inserted into the inside of the limiting groove 708.

[0036] It should be noted that the limiting groove 708 and rotating groove 704 are respectively adapted to the limiting ring 709 and rotating block 703, and the limiting ring 709 and rotating block 703 are respectively fitted to the inner wall of one side of the limiting groove 708 and rotating groove 704. The through hole 707 is used to connect the limiting groove 708 and rotating groove 704, and the diameter of the through hole 707 is larger than the diameter of the threaded rod 711. The limiting ring 709 and rotating block 703 are both fixedly connected to the threaded rod 711. Through this design, the threaded rod 711 is connected to the pressing block 705, so that the threaded rod 711 can move... When moving, the pressing block 705 is moved; the extrusion groove 701 is adapted to the back of the pressing block 705, so that the back of the pressing block 705 can be inserted into the extrusion groove 701. Multiple pressing blocks 705 are respectively arranged on both sides of the split ring 6. By blocking the pressing block 705, the split ring 6 cannot slide in the middle of the inner ring 1, thereby connecting the split ring 6 and the inner ring 1; the hexagonal groove 702 is adapted to the hexagonal wrench, so that the hexagonal wrench is inserted into one side of the rotating block 703 through the hexagonal groove 702, and the rotating block 703 is rotated by the hexagonal wrench.

[0037] Furthermore, when it is necessary to separate the split ring 6, first rotate the rotating block 703 so that the threaded rod 711 moves away from the inner ring 1, and the threaded rod 711 drives the pressing block 705 to move out of the extrusion groove 701. Then rotate the pressing block 705 so that the pressing block 705 separates from the split ring 6, and then remove the split ring 6 from the middle of the inner ring 1.

[0038] 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.
