Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rolling bearings, and specifically relates to a rolling bearing. Background Technique
[0002] A rolling bearing is a bearing used to support mechanical components. It mainly relies on rolling elements (such as balls, rollers, etc.) to roll between the inner and outer rings to reduce friction, thereby improving mechanical efficiency. Rolling bearings are widely used in various fields such as machinery, automobiles, aerospace, and household appliances, and are an essential and important part of modern mechanical equipment.
[0003] During the actual use of existing rolling bearings, with the increase of the use time for a long time, the lubrication performance inside the bearing will decline accordingly, affecting the use effect of the rolling bearing. For this reason, we propose a rolling bearing. Content of the Utility Model
[0004] The purpose of the utility model is to provide a rolling bearing to solve the problem that during the actual use of existing rolling bearings, with the increase of the use time for a long time, the lubrication performance inside the bearing will decline accordingly, affecting the use effect of the rolling bearing as mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A rolling bearing includes an inner ring arranged inside the outer ring, rolling elements arranged inside the outer ring and the inner ring, a dust cover arranged at the gap position on the side of the outer ring and the inner ring, and a lubrication component arranged on the inner wall of the outer ring.
[0006] Preferably, the lubrication component includes a movable block, a spring, a sponge block, and a card slot. Four equidistant card slots are opened on the inner wall of the outer ring. Sponge blocks are embedded in the four card slots. Four equidistant springs are adhesively connected to the inner wall of the card slot. The outer end of the spring is fixedly connected with a movable block. The outer wall of the movable block is arc-shaped, and the outer end of the movable block extends outside the card slot.
[0007] Preferably, brush strips are adhesively connected to both ends of the inner wall of the outer ring. The brush strips are evenly arranged around the inner wall of the outer ring, and adjacent brush strips are arranged in a mirror image.
[0008] Preferably, equidistant heat dissipation holes are opened on the surface of the dust cover, and a dust-proof net is fixedly connected inside the heat dissipation holes.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. The utility model uses the cooperating movable block, spring, sponge block and card slot. Card slots are opened around the inner wall of the outer ring to install springs to connect the movable block, and sponge blocks are also embedded in the card slots. Lubricating oil is drip-irrigated into the sponge blocks. When the inner ring and the outer ring rotate relative to each other, the rolling elements between the outer ring and the inner ring contact the movable block. The movable block is stressed to compress the spring and simultaneously compress the sponge block. The lubricating oil inside the sponge block is extruded to contact the rolling elements, thereby lubricating the rolling elements. At the same time, the sponge block can recover the lubricating oil overflowing between the inner ring and the outer ring, ensuring the long-term lubrication effect of the rolling bearing.
[0011] 2. The utility model uses the brush strips provided. Equally spaced brush strips are adhesively connected to the inner wall of the outer ring. When the inner ring and the outer ring rotate relative to each other, the brush strips contact the surface of the inner ring and the rolling elements, brushing the lubricating oil on the surface of the inner ring and the rolling elements evenly, ensuring the uniform lubrication effect of the rolling elements.
[0012] 3. The utility model uses the cooperating heat dissipation holes and dust-proof nets. Equally spaced heat dissipation holes are opened on the surface of the dust-proof cover, and dust-proof nets are arranged inside the heat dissipation holes, achieving a certain heat dissipation effect between the inner ring and the outer ring.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Embodiment
[0019] Please refer to Figures 1-3, A rolling bearing shown in the figure, including an inner ring 4 provided inside the outer ring 1, rolling elements provided inside the outer ring 1 and the inner ring 4, a dust cover 2 provided at the side gap position between the outer ring 1 and the inner ring 4, and a lubrication component 7 provided on the inner wall of the outer ring 1. The lubrication component 7 includes a movable block 701, a spring 702, a sponge block 703, and a card slot 704. Four equidistant card slots 704 are opened on the inner wall of the outer ring 1. The sponge block 703 is embedded in the four card slots 704. Four equidistant springs 702 are glued to the inner wall of the card slot 704. The outer end of the spring 702 is fixedly connected to the movable block 701. The outer wall of the movable block 701 is arc-shaped, and the outer end of the movable block 701 extends outside the card slot 704; card slots 704 are opened around the inner wall of the outer ring 1 to install springs 702 to connect the movable block 701, and a sponge block 703 is also embedded in the card slot 704. Lubricating oil is drip-irrigated into the sponge block 703. When the inner ring 4 and the outer ring 1 rotate relative to each other, the rolling elements between the outer ring 1 and the inner ring 4 contact the movable block 701. The movable block 701 is pressed against the spring 702 and simultaneously compresses the sponge block 703. The lubricating oil inside the sponge block 703 is squeezed out and contacts the rolling elements, thereby lubricating the rolling elements. At the same time, the sponge block 703 can recover the lubricating oil overflowing between the inner ring 4 and the outer ring 1, ensuring the long-term lubrication effect of the rolling bearing.
[0020] On the basis of the foregoing solution, brush strips 6 are glued to both ends of the inner wall of the outer ring 1. The brush strips 6 are evenly arranged around the inner wall of the outer ring 1, and adjacent brush strips 6 are arranged in a mirror image; equidistant brush strips 6 are glued to the inner wall of the outer ring 1. When the inner ring 4 and the outer ring 1 rotate relative to each other, the brush strips 6 contact the surface of the inner ring 4 and the rolling elements, brushing the lubricating oil on the surface of the inner ring 4 and the rolling elements evenly, ensuring the uniform lubrication effect of the rolling elements.
[0021] As a further solution of the present invention, heat dissipation holes 3 are opened at equal distances on the surface of the dust cover 2, and a dust-proof net 5 is fixedly connected inside the heat dissipation holes 3; heat dissipation holes 3 are opened at equal distances on the surface of the dust cover 2, and a dust-proof net 5 is arranged inside the heat dissipation holes 3, which plays a certain heat dissipation effect between the inner ring 4 and the outer ring 1.
[0022] It should be noted that the present utility model is a rolling bearing. When the rolling bearing is in use, the inner ring 4 and the outer ring 1 rotate relative to each other. On the one hand, the rolling elements between the outer ring 1 and the inner ring 4 contact the movable block 701. The movable block 701 is stressed to squeeze the spring 702 and at the same time compress the sponge block 703. The lubricating oil inside the sponge block 703 is extruded to contact the rolling elements, thereby achieving a lubricating effect on the rolling elements. At the same time, the sponge block 703 can recover the lubricating oil overflowing between the inner ring 4 and the outer ring 1. On the other hand, the brush strip 6 contacts the surface of the inner ring 4 and the rolling elements, and has a brushing effect on the lubricating oil on the surface of the inner ring 4 and the rolling elements, ensuring the uniform lubricating effect of the rolling elements. The heat dissipation holes 3 opened on the surface of the dust-proof cover 2 are connected to the dust-proof net 5, which has a certain heat dissipation effect between the inner ring 4 and the outer ring 1, ensuring the actual use effect of the rolling bearing.
