Abstract
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] Rubber rings, also known as rubber seals, are annular covers composed of one or more parts. They are fixed to one ring or washer of a bearing and contact or form a narrow labyrinth gap with the other ring or washer to prevent lubricating oil leakage and foreign matter intrusion. During long-term use, rubber rings are prone to deformation due to frequent compression, and prolonged exposure to corrosive environments can cause chemical changes in their internal structure, leading to decreased elasticity and ultimately, a less effective seal.
[0003] Currently, rubber rings are prone to deformation due to frequent compression during long-term use, and their internal structure undergoes chemical changes when exposed to corrosive environments for extended periods, resulting in decreased elasticity and ultimately failing to provide a good sealing effect. Utility Model Content
[0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides a corrosion-resistant rubber ring.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a corrosion-resistant rubber ring, including a first support layer, a corrosion-resistant rubber layer bonded to the outside of the first support layer, a sheath tube provided in the middle of the inner side of the first support layer, the inside of the sheath tube being filled with a tensile rubber layer, a second support layer fixedly connected to the outside of the sheath tube, and the outside of the second support layer being in contact with the inner wall of the first support layer.
[0006] Furthermore, aggregate is filled between the inner side of the second support layer and the outer layer of the sheath to provide support and prevent deformation.
[0007] Furthermore, a slow-release solvent is filled between the outer side of the second support layer and the inner layer of the first support layer.
[0008] Furthermore, the surface of the first support layer is provided with several sets of tiny holes.
[0009] The beneficial effects of this utility model are: the corrosion resistance of the rubber ring surface is enhanced by the corrosion-resistant rubber layer made of fluororubber, the overall strength is increased by the cooperation of the tensile rubber layer made of butyl rubber and the sleeve tube, and the deformation of the rubber ring is prevented. The slow-release solvent flows slowly into the space between the first support layer and the corrosion-resistant rubber layer through the holes of the first support layer to prevent the corrosion-resistant rubber layer from falling off, thus making the sealing effect of the rubber ring better.

[0017] like Figure 2 As shown, the outer side of the sheath 4 is fixedly connected to the second support layer 3. The outer side of the second support layer 3 is in contact with the inner wall of the first support layer 2. The space between the inner side of the second support layer 3 and the outer layer of the sheath 4 is filled with aggregate 6 to provide support and prevent deformation.
[0018] like Figure 2 As shown, the surface of the first support layer 2 is provided with several sets of small holes. The outer side of the second support layer 3 and the inner layer of the first support layer 2 are filled with a slow-release solvent 5.
