Description

Technical Field

[0001] This utility model belongs to the technical field of bearing seals, and in particular relates to a rubber seal for bearings that prevents detachment. Background Technology

[0002] A rolling bearing is a precision mechanical component that transforms the sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing frictional losses. A rolling bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The inner ring mates with the shaft and rotates with it; the outer ring mates with the bearing housing and provides support; the rolling elements are evenly distributed between the inner and outer rings by the cage, and their shape, size, and number directly affect the performance and lifespan of the rolling bearing; the cage ensures the even distribution of the rolling elements, guides their rotation, and provides lubrication.

[0003] Bearings are commonly used mechanical components. To ensure their smooth rotation, a lubricating medium is usually added inside them. At the same time, to protect the lubricating medium from contamination, seals are usually installed on the bearings to seal them, preventing leakage and contamination. However, ordinary seals are often simple in structure, easy to fall off, and their effect is not ideal. Utility Model Content

[0004] This utility model provides a rubber seal for bearings to prevent detachment, aiming to solve the problem that general seals are often simple in structure, easy to detach, and have unsatisfactory effect.

[0005] This utility model is implemented as follows: a rubber seal for bearings that prevents detachment, comprising an inner bearing ring, an outer bearing ring, and an annular sealing ring;

[0006] The outer ring surface of the bearing outer ring and the outer ring surface of the bearing inner ring are respectively provided with an outer ring groove and an inner ring groove. The outer ring surface of the sealing ring is provided with a sealing lip that matches the outer ring groove of the bearing outer ring inner ring surface. The inner surface of the sealing ring is provided with a reinforcing lip.

[0007] When the sealing ring is installed between the outer ring and the inner ring of the bearing, the outer surface of the reinforcing lip is in contact with the inner side of the inner ring surface of the outer ring of the bearing.

[0008] Preferably, the outer surface of the reinforcing lip is provided with anti-slip texture.

[0009] Preferably, the inner circumferential surface of the sealing ring is provided with an extended lip.

[0010] Preferably, the sealing ring, the sealing lip, the reinforcing lip, and the extending lip are integrally injection molded.

[0011] Preferably, the sealing ring has an annular metal skeleton inside.

[0012] Preferably, the sealing ring, the sealing lip, the reinforcing lip, and the extended lip are all made of rubber.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The bearing anti-detachment rubber seal of this utility model, by setting a reinforcing lip, after the seal structure is installed inside the bearing, the outer surface of the reinforcing lip will fit against the inner ring surface of the bearing outer ring. Under the action of friction, the seal can be permanently and firmly installed inside the bearing. Furthermore, the reinforcing lip is also provided with anti-slip texture, which further improves the friction of the structure, thereby improving the installation stability of the seal and making it less likely to detach from the bearing.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a rubber seal for preventing the bearing from falling off, comprising an inner bearing ring 1, an outer bearing ring 2, and an annular sealing ring 4;

[0021] The outer ring surface of the bearing outer ring 2 and the outer ring surface of the bearing inner ring 1 are respectively provided with an outer ring groove and an inner ring groove. The outer ring surface of the sealing ring 4 is provided with a sealing lip 5 that matches the outer ring groove of the inner ring surface of the bearing outer ring 2. The inner surface of the sealing ring 4 is provided with a reinforcing lip 7.

[0022] When the sealing ring 4 is installed between the outer ring 2 and the inner ring 1 of the bearing, the outer surface of the reinforcing lip 7 is in contact with the inner side of the inner ring surface of the outer ring 2 of the bearing.

[0023] The outer surface of the reinforced lip 7 is provided with anti-slip texture 8.

[0024] In this embodiment, after the sealing structure is installed inside the bearing, the outer surface of the reinforcing lip 7 will fit against the inner ring surface of the bearing outer ring. Under the action of friction, the sealing can be permanently and firmly installed inside the bearing. Furthermore, the reinforcing lip 7 is provided with anti-slip texture 8, which further improves the friction of the structure, thereby improving the installation stability of the sealing and making it less likely to detach from the bearing.

[0025] Furthermore, the inner annular surface of the sealing ring 4 is provided with an extended lip 6.

[0026] The sealing ring 4, sealing lip 5, reinforcing lip 7, and extension lip 6 are integrally injection molded.

[0027] The sealing ring 4, sealing lip 5, reinforcing lip 7, and extension lip 6 are all made of rubber.

[0028] In this embodiment, the seal is integrally molded and made of rubber, which has a certain elasticity. Under the action of elasticity, the reinforcing lip 7 will always fit against the inner surface of the outer ring 2 of the bearing, ensuring the stability of the seal after it is fixed.

[0029] Furthermore, the sealing ring 4 has an annular metal skeleton 3 inside.

[0030] In this embodiment, the metal frame 3 serves as a support, ensuring that the overall shape of the seal does not undergo excessive deformation.
