Description

Technical Field

[0001] This utility model relates to the field of rubber ring technology, and in particular to a corrosion-resistant rubber ring. Background Technology

[0002] A rubber ring, also known as a rubber seal, is an annular cover composed of one or more parts. It is fixed to one of the bearing rings or washers and contacts or forms a narrow labyrinth gap with the other ring or washer to prevent lubricating oil leakage and foreign objects from entering.

[0003] Therefore, a corrosion-resistant rubber ring is proposed.

[0004] For example, the prior art Chinese patent publication number "CN220668356U" provides a corrosion-resistant rubber ring, which includes a rubber ring, a first corrosion-resistant film and a second corrosion-resistant film. The first corrosion-resistant film and the second corrosion-resistant film are respectively disposed on the inner ring and the outer ring of the rubber ring, and a reinforcing groove is formed on the top and bottom surfaces of the rubber ring. A waterproof coating is provided on the inner side of the reinforcing groove and the outer side of the rubber ring, and the waterproof coating is located on the outer side of the first corrosion-resistant film and the second corrosion-resistant film.

[0005] This device enhances the corrosion resistance of ordinary rubber protective rings by incorporating a rubber ring, a first corrosion-resistant film, and a second corrosion-resistant film. This allows the rubber ring to resist the intrusion of other substances to a certain extent when in contact with them, preventing its lifespan from being significantly shortened by external factors and reducing the frequency of maintenance and operating costs.

[0006] Existing corrosion-resistant rubber rings suffer from friction and wear on both their inner and outer surfaces during use, leading to damage to these surfaces. This allows external dust and impurities to adhere to the inner surface of the rubber ring, further abrading the protective structures on both the inner and outer surfaces and reducing its corrosion resistance. Consequently, the rubber ring fails to provide adequate protection for the corrosion-resistant protective structures on its inner and outer surfaces. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies where both the inner and outer surfaces of the rubber ring are subject to friction and wear, resulting in damage to both surfaces. This damage allows external dust and impurities to adhere to the inner surface of the rubber ring, further eroding the protective structure of both surfaces and reducing the rubber ring's corrosion resistance. Therefore, this invention proposes a corrosion-resistant rubber ring.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] Design a corrosion-resistant rubber ring, comprising a base layer, a first corrosion-resistant layer bonded to the outer side of the base layer, an outer protective layer connected to the outer side of the first corrosion-resistant layer, a gap block fixed to the outer surface of the outer protective layer, a buffer layer bonded to the inner surface of the base layer, a second corrosion-resistant layer connected to the inner surface of the buffer layer, and an inner protective layer connected to the inner surface of the second corrosion-resistant layer.

[0010] Furthermore, the outer protective layer includes a puncture-resistant layer, a high-temperature resistant layer, and a wear-resistant layer. The puncture-resistant layer is wrapped around the outer surface of the first corrosion-resistant layer. The high-temperature resistant layer is bonded to the outside of the puncture-resistant layer. The wear-resistant layer is connected to the outside of the high-temperature resistant layer. The gap block is uniformly fixed to the outer surface of the wear-resistant layer.

[0011] Furthermore, the first corrosion-resistant layer includes an anti-permeability layer, an aging-resistant layer, and an oil-resistant layer. The anti-permeability layer is wrapped around the outer surface of the substrate layer, the aging-resistant layer is bonded to the outer surface of the anti-permeability layer, and the oil-resistant layer is connected to the outer surface of the aging-resistant layer.

[0012] Furthermore, the substrate layer is made of rubber, and the buffer layer is made of polyurethane elastomer.

[0013] Furthermore, the second corrosion-resistant layer is made of polyurethane film material, and the inner protective layer is made of polyvinyl chloride material.

[0014] Furthermore, the puncture-resistant layer is made of woven metal wire, the high-temperature resistant layer is made of inorganic silicon high-temperature resistant ceramic material, and the wear-resistant layer and the gap block are both made of butadiene rubber material.

[0015] Furthermore, the anti-permeability layer is made of graphene, the aging-resistant layer is made of cyanopolymer coating, and the oil-resistant layer is made of chlorosulfonated polyethylene.

[0016] The corrosion-resistant rubber ring proposed in this utility model has the following advantages:

[0017] 1. This utility model improves the corrosion protection performance of the inner and outer sides of the rubber ring and extends the service life of the rubber ring by setting a second corrosion-resistant layer and a first corrosion-resistant layer on the inner and outer surfaces of the substrate layer, respectively, and the first corrosion-resistant layer includes an anti-permeability layer, an aging-resistant layer and an oil-resistant layer.

[0018] 2. This utility model provides an inner protective layer and a first protective layer on the outer sides of the second corrosion-resistant layer and the first corrosion-resistant layer on both the inner and outer sides of the rubber ring, respectively. The first protective layer includes a puncture-resistant layer, a high-temperature resistant layer, and a wear-resistant layer. Gap blocks are uniformly fixed on the surface of the wear-resistant layer. Therefore, it can provide protection for the corrosion-resistant protective structure inside and outside the rubber ring, reduce external friction and wear on the corrosion-resistant protective structure, thereby improving the safety of the corrosion-resistant protective structure and reducing friction and wear on the inner and outer surfaces of the rubber ring.
