Description

Technical Field

[0001] The utility model relates to the technical field of industrial machinery, in particular to a waterproof bearing sealing ring. Background Art

[0002] Bearing sealing rings are key components used to prevent the leakage of lubricant inside the bearing and the entry of external impurities. They are usually made of materials such as metal, plastic or rubber. They are installed between the inner and outer rings of the bearing and ensure the sealing effect through close fit. There are various designs of sealing rings, including contact and non-contact types, to adapt to different working environments and performance requirements. In rotating equipment, bearing sealing rings not only protect bearings from contamination, but also help extend the service life of bearings and maintain the normal operation of equipment.

[0003] After searching, the document of announcement number "CN219432276U" mentioned that "the utility model discloses a waterproof and low-friction sealing ring bearing, which relates to the field of bearing technology, including an outer ring and an inner ring, wherein the outer ring is located outside the inner ring, and a plurality of equally spaced balls are rotatably connected between the outer ring and the inner ring." When in use, the outer ring and the inner ring are provided with an outer annular groove to ensure that the outer ring, the inner ring and the balls are not easy to move up and down, and the outer ring and the inner ring are dustproof and waterproof by providing a sealing ring and a limiting annular groove and using the sealing ring to ensure that the balls are not easily corroded and damaged. By setting up multiple sealing balls, the friction between the outer ring and the inner ring and the sealing ring is reduced, and by cooperating with the sealing ring and the first sphere, it is ensured that the sealing ring is not easily separated from the outer ring and the inner ring. By setting up the first sphere and the second sphere, the friction between the sealing ring and the limiting annular groove is reduced, ensuring that the rotation of the outer ring and the inner ring is smoother, and at the same time improving the dustproof and waterproof effect of the sealing ring and the sealing ring. However, during the use of the bearing, if liquid leakage and impurities infiltrate, it is easy to cause the lubrication effect of the bearing, thereby affecting the normal operation of the bearing.

[0004] To this end, we provide a waterproof bearing sealing ring to solve the above problems. Utility Model Content

[0024] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] See also Figure 1-4 A waterproof bearing sealing ring includes a bearing outer body 1 and a bearing sealing ring waterproof mechanism 2, wherein the bearing sealing ring waterproof mechanism 2 is provided on the inner side of the bearing outer body 1;

[0026] The bearing sealing ring waterproof mechanism 2 includes an outer waterproof component 21 arranged on the inner side of the bearing outer body 1 , and inner waterproof components 22 are arranged on the upper and lower sides of the outer waterproof component 21 .

When needed, the semi-solid lubricating oil 213 in the driven shaft ring 212 can provide sufficient lubricity after the bearing sealing cover 216 is inserted into the driven shaft ring 212, and the semi-solid lubricating oil 213 has sufficient sealing and lubricity, which can reduce the flow of moisture into the bearing inner body 211, thereby achieving a waterproof effect, and the semi-solid lubricating oil 213 is not easily soluble in water and can support long-term use.

[0028] In the present invention, the connecting shaft ring 214 and the soft rubber gasket 215 are connected by a card groove, and the connecting shaft ring 214 and the soft rubber gasket 215 are tightly fitted, and the connecting shaft ring 214 and the bearing sealing cover 216 form a sealing structure through the soft rubber gasket 215. When it is needed to use, before installing the bearing sealing cover 216, the soft rubber gasket 215 is pre-heated to a semi-solid state. After the bearing sealing cover 216 is installed on the connecting shaft ring 214, the bearing sealing cover 216 can be effectively adhered to the connecting shaft ring 214 for sealing. In the subsequent use process, the heat absorbed by the bearing outer body 1 will continue to soften the soft rubber gasket 215 in the connecting shaft ring 214, thereby enhancing the sealing effect.

When needed, the plastic sealing ring 222 can protect the bearing ball 221 from dislocation, and because the plastic sealing ring 222 is more closely fitted with the gap between the bearing outer body 1 and the bearing inner body 211, it can effectively reduce the intrusion of water flow and improve the protection effect.

[0031] In the present invention, the graphite coating 223 and the plastic sealing ring 222 are adhesively connected. The graphite coating 223 is a thin film structure. When needed, the graphite coating 223 can effectively reduce the friction coefficient between the plastic sealing ring 222 and the bearing ball 221 to achieve a lubricating effect.

[0032] It can be seen from the above technical solution that when in use, the bearing inner body 211 is first fixed to the position where it needs to be used.
