Description

Technical Field

[0001] The utility model relates to the technical field of sealing elements, in particular to a rubber sealing ring with an anti-sliding block. Background Art

[0002] Rubber seals are a key component widely used in various mechanical equipment. Their primary function is to prevent lubricating oil from leaking out of the equipment while also preventing dust, moisture, and other contaminants from entering the equipment, thereby protecting the equipment's normal operation. Rubber seals typically consist of one or more parts, fixed to the inner or outer ring of a bearing, contacting another bearing ring or washer, or forming a narrow labyrinthine gap to achieve a sealing effect.

[0003] However, traditional rubber seals have structural limitations. Most often, they are simple ring-shaped. While this single design provides adequate sealing in many basic applications, it falls short in complex operating conditions. Particularly in environments with high pressure or intense vibration, the seals can easily slip within their mounting grooves due to the lack of an effective anti-slip mechanism. This slippage disrupts the close contact between the sealing surfaces, leading to leakage. Leakage not only wastes resources but, more seriously, can lead to unstable equipment operation, reduced performance and reliability, and even pose safety risks. Currently, no effective solution has been proposed to address these technical issues. Utility Model Content

[0007] Furthermore, in order to enhance the anti-slip effect of the contact surface of the sealing ring and prevent the sealing ring from sliding under high pressure or strong vibration conditions, the anti-slip mechanism includes a groove provided on the outer ring, an anti-sliding block provided inside the groove, the anti-sliding block matches the groove, a clamping column is provided at the bottom end of the anti-sliding block, a clamping groove is provided inside the outer ring, and the clamping column matches the clamping groove.

[0008] Furthermore, in order to enhance the connection effect between the anti-sliding block and the outer ring, sliding plates are provided at both ends of the anti-sliding block, and a sliding groove is provided on the outer ring, and the sliding plates match the sliding groove.

[0009] Furthermore, in order to improve the performance and reliability of the rubber sealing ring and make it more suitable for various complex use environments, the first protective layer includes a chemical corrosion resistant coating and a wear-resistant layer. The wear-resistant layer is arranged on the outside of the chemical corrosion resistant coating, and the wear-resistant layer is arranged on the inside of the inner ring.

[0010] Furthermore, the constituent material of the chemical corrosion resistant coating is polyurethane, and the constituent material of the wear-resistant layer is fluororubber.

[0011] Furthermore, the second protective layer includes a reinforcement layer and an anti-corrosion layer. The anti-corrosion layer is arranged on the outside of the reinforcement layer, and the reinforcement layer is arranged on the outside of the outer ring.

[0012] Furthermore, the anti-corrosion layer is made of polytetrafluoroethylene material.

[0013] The beneficial effects of the utility model are:

[0014] (1) By setting up an anti-slip mechanism, the stability of the sealing ring under harsh conditions can be significantly improved, and the risk of sealing failure caused by sliding can be reduced. These anti-slip blocks can change the contact mode of the sealing ring and increase the friction between the sealing ring and the installation groove, thereby ensuring continuous close contact between the sealing surface.
