Abstract
Description
Technical Field
[0001] The utility model relates to the field of bearings, in particular to a bearing provided with a dustproof component. Background Art
[0002] A bearing equipped with a dustproof assembly is mainly composed of an inner ring, an outer ring, rolling elements, a cage, and a dustproof assembly. The inner ring fits tightly with the shaft, while the outer ring fits with the bearing seat of the equipment. The rolling elements are placed between the inner and outer rings, and the cage is used to evenly distribute the rolling elements to ensure smooth rolling. The dustproof assembly is a key feature of this bearing, and usually includes components such as a sealing lip, a dustproof cover, or a dustproof sealing ring that fits on the edge of the inner or outer ring. These dustproof components can effectively prevent impurities such as dust, debris, and moisture from entering the interior of the bearing, reducing the wear and erosion of impurities on the rolling elements and raceways, greatly extending the service life of the bearing, and ensuring the stable and efficient operation of the equipment in dusty environments;
[0003] A search revealed a Chinese patent with publication number CN202991853U, which discloses a bearing. The patent describes a technical solution that further reduces frictional resistance when the bearing is loaded, significantly increasing the bearing's service life, by adding another layer of rollers to a ring of rollers.
[0004] In this solution, friction is reduced by adding a layer of beads. However, the beads in this device are exposed to the outside. When they are oiled, external dust will directly adhere to the beads. The accumulation of dust will cause more serious wear of the beads, reducing their service life. In addition, when installing the dustproof component, it is time-consuming and labor-intensive to install it by screws or welding, which reduces work efficiency. In order to solve this technical problem, the utility model proposes a bearing provided with a dustproof component. Summary of the Invention

[0014] (3) Beneficial effects
[0015] The utility model provides a bearing equipped with a dustproof component. It has the following beneficial effects:
[0016] (1) When installing the dustproof plate, the inner positioning column is aligned with the annular groove of the outer ring and inserted. Because the slider is tilted on both sides, the slider is pushed and compressed during insertion to slide into the inner cavity. After the positioning column is fully inserted, the dustproof plate is rotated and the positioning column moves accordingly. When the slider reaches the inner hole position, the spring rebounds and the slider bounces into the inner hole to complete the positioning and fixation. This combination solves the problems of inconvenient installation and poor dustproof effect of the existing bearing dustproof structure. The design uses the positioning column, slider, spring and other components to cleverly cooperate to achieve fast and accurate installation of the dustproof plate, effectively preventing dust from entering the rotating bead area. At the same time, the fixed frame stabilizes and limits the rotating bead, ensuring stable operation of the equipment, reducing performance degradation and damage caused by dust, and improving the reliability and durability of the device.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0024] See also Figure 1-5 , the utility model provides a technical solution:
[0025] Embodiment 1: A bearing with a dustproof assembly includes an outer ring 1 and an inner ring 2, a plurality of rotating beads 4 are arranged between the outer ring 1 and the inner ring 2, dustproof plates 8 are arranged on both sides of the outer ring 1 and the inner ring 2, annular grooves 9 are opened inside both sides of the outer ring 1, and a positioning column 10 is fixedly connected to the inner side wall of each dustproof plate 8, and the positioning column 10 corresponds to the annular groove 9, and the positioning column 10 is slidably connected in the annular groove 9, and the dustproof plate 8 corresponds to the rotating beads 4, and an inner groove 9 is opened on both sides of the end of each positioning column 10. Cavity 14, each inner cavity 14 is fixedly connected to a fixing column 15, the other end of each fixing column 15 is fixedly connected to a spring 11, the other end of each spring 11 is fixedly connected to a slider 12, and the slider 12 is slidably connected in the inner cavity 14, a pair of inner holes 13 are opened inside the outer ring 1, and the inner holes 13 correspond to the slider 12, and the slider 12 is slidably connected in the inner holes 13, the positioning columns 10 on both sides are centrally symmetrical, the inner holes 13 on both sides are centrally symmetrical, and the inner holes 13 are opened on both sides of the annular groove 9.
[0026] When installing the dust shield 8, first precisely align the positioning posts 10 on the inner walls of both dust shields 8 with the annular grooves 9 on either side of the outer ring 1. Then, smoothly insert the positioning posts 10 directly into the annular grooves 9. Because both sides of the slider 12 are designed to be inclined, when the positioning posts 10 slide into the annular groove 9, the slider 12 is subjected to a compressive force from the inner wall of the annular groove 9. Under the action of this compressive force, the slider 12 is pushed in a specific direction, simultaneously compressing the spring 11 on the fixing post 15, causing the slider 12 and the spring 11 to gradually slide into the inner cavity 14. When the positioning posts 10 are fully inserted into the annular groove 9, rotate the dust shield 8. As the dust shield 8 rotates, the two symmetrical positioning posts 10 connected to it will also move accordingly. When the slider 12 moves to the inner hole 13, the spring 11 on the fixing column 15, which was originally in a compressed state, will quickly rebound due to its own resilience, and the slider 12 will be pushed into the inner hole 13, thereby achieving the positioning and fixing between the dustproof plate 8 and the outer ring 1. This close coordination between the various components can quickly and conveniently complete the installation of the dustproof plate 8. After the dustproof plate 8 is installed, it can effectively prevent dust from entering the rotating ball 4 between the outer ring 1 and the inner ring 2, avoiding dust from adversely affecting the rotation of the rotating ball 4, and ensuring its smooth and stable rotation.
[0027] Example 2: The difference between this example and Example 1 is that, the outer wall of the inner ring 2 is fixedly connected to the fixing frame 3, and the rotating bead 4 is rotatably connected in the fixing frame 3, the inner wall of the outer ring 1 is fixedly connected to the insulating layer 5, the outer wall of the outer ring 1 is fixedly connected to the anti-slip layer 6, and both sides of the outer wall of the inner ring 2 are fixedly connected to oil deflector rings 7, and the rotating bead 4 is arranged between the oil deflector rings 7 on both sides.
[0028] When lubricating the rotating ball 4, the oil deflector 7 plays a crucial role, effectively preventing oil splashing and maintaining a clean and safe working environment. The fixing bracket 3 limits the rotating ball 4, ensuring stable rotation within a specified range. Furthermore, the anti-slip layer 6 increases friction between components, providing an anti-slip effect, while the insulating layer 5 provides excellent insulation, ensuring the safety and reliability of the equipment during operation.
[0029] During operation, when the staff uses the bearing, it is necessary to prevent dust from entering the bearing. At this time, the positioning columns 10 on the inner wall of the dustproof plates 8 on both sides are aligned with the annular grooves 9 on both sides of the outer ring 1, and the positioning columns 10 are directly inserted into the annular grooves 9. Since both sides of the slider 12 are inclined, when sliding into the annular groove 9, the slider 12 will be squeezed and the spring 11 on the fixed column 15 will be compressed, so that the slider 12 and the spring 11 will slide into the inner cavity 14. After the positioning column 10 is inserted into the annular groove 9, the two symmetrical The positioning column 10 moves, and when the slider 12 moves to the position of the inner hole 13, the spring 11 on the fixing column 15 will rebound the slider 12 into the inner hole 13 through resilience, thereby positioning and fixing it. Through the cooperation between them, the dustproof plate 8 is quickly installed, thereby effectively preventing dust from entering the rotating bead 4 between the outer ring 1 and the inner ring 2. When the rotating bead 4 is oiled, the oil deflector 7 can be used to prevent oil from splashing, the fixing frame 3 serves to limit the rotating bead 4, and the anti-slip layer 6 and the insulating layer 5 provide anti-slip and insulation.
