Description
Technical Field
The utility model belongs to the technical field of the sealing member and specifically relates to a wear-resisting type rubber seal spare.
Background
The seal is a material or a part that prevents fluid or solid particles from leaking from between adjacent bonding surfaces and prevents foreign substances such as dust and moisture from intruding into parts inside the machine equipment. Although the rubber sealing element is small, the rubber sealing element has the function of becoming a basic part and an accessory in the main national economy industries such as national defense, chemical industry, petroleum, coal, transportation, mechanical manufacturing and the like, and plays a very important role in the development of the national economy.
However, the rubber sealing element in the prior art is worn in the using process, so that the sealing failure is caused, the leakage is caused, and the service life of the rubber sealing element is greatly influenced.
Disclosure of Invention
To the problem that exists among the prior art, the utility model provides a wear-resisting type rubber seal spare, its wearability is stronger, can prolong its life.
In order to achieve the above purpose, the utility model provides a following technical scheme: the wear-resistant rubber sealing element comprises an annular body, sealing rings are arranged on the end faces of the body at two ends in the axial direction, the sealing rings are respectively arranged along the inner edge and the outer edge of the body, wear-resistant patterns are arranged between the sealing rings, and a supporting structure is arranged on the radial outer wall of the body.
By adopting the technical scheme, the sealing ring can enhance the sealing performance of the inner edge and the outer edge of the body to ensure that the sealing effect is better, and can increase the wear resistance of the positions of the inner edge and the outer edge of the body, the sealing patterns are used for improving the wear resistance of the axial end face of the body and greatly prolonging the service life of the body, and the supporting structure is arranged on the radial outer wall of the body to prevent the body from being worn and thinned, so that the structural strength of the body is prevented from being reduced.
Further, the wear-resistant patterns are arranged in a honeycomb shape, and the height of the wear-resistant patterns is flush with that of the sealing ring.
By adopting the technical scheme, the firmness degree and the pressure resistance of the honeycomb structure are stronger, so that the whole body of the wear-resistant decorative pattern has certain structural strength after being thinned due to wear, the body is prevented from being easily deformed due to the reduction of the structural strength, and the sealing is not tight.
Furthermore, the supporting structure comprises reinforcing rings arranged at two axial ends of the outer wall and reinforcing convex ribs connected with the two reinforcing rings.
Adopt above-mentioned technical scheme, through consolidating protruding muscle to the connection of the reinforcement ring at both ends, make the three fuse, consolidate protruding muscle and play the effect that supports to two reinforcement rings, make holistic structural strength higher.
Furthermore, the reinforcing convex ribs are of an X-shaped structure, and are arranged in a plurality and distributed along the circumferential direction.
By adopting the technical scheme, the X-shaped structure is connected with the two reinforcing rings to form an upper triangle and a lower triangle, and the triangle has the advantage of strong stability, so that the supporting force of the reinforcing convex ribs on the two reinforcing rings is stronger.
Further, a plurality of through holes are formed in the body along the circumferential direction at equal intervals, and a circle of dustproof ring is arranged outside each through hole.
By adopting the technical scheme, the dustproof ring can play a role in retaining water and ash, so that the openings at the two axial ends of the through hole are sealed with the contact part through the dustproof ring, and external dust or moisture is prevented from entering the through hole.

Detailed Description
The following will further describe the embodiments of the present invention with reference to the drawings and examples.
As shown in fig. 1-3, the wear-resistant rubber sealing member includes an annular body 1, sealing rings 2 are disposed on end faces of two ends of the body 1 along an axial direction, the sealing rings 2 are respectively disposed along an inner edge and an outer edge of the body 1, a wear-resistant pattern 3 is disposed between the sealing rings 2, and a support structure 4 is disposed on an outer wall of the body 1 along a radial direction. The sealing ring 2 can enhance the sealing performance of the inner edge and the outer edge of the body 1 to ensure better sealing effect, and can increase the wear resistance of the inner edge and the outer edge of the body 1, the sealing pattern is used for improving the wear resistance of the axial end face of the body 1 to greatly prolong the service life of the body, and the supporting structure 4 is arranged on the radial outer wall of the body 1 to prevent the structural strength of the body 1 from being reduced after the body 1 is worn and thinned.
The wear-resistant patterns 3 are arranged in a honeycomb shape, and the height of the wear-resistant patterns is flush with that of the sealing ring 2. The firmness and the pressure resistance of the honeycomb structure are stronger, so that the whole body of the wear-resistant pattern 3 has certain structural strength after being worn and thinned, the body 1 is prevented from being easily deformed due to the reduction of the structural strength, and the sealing is not tight.
The support structure 4 includes reinforcing rings 41 respectively provided at both axial end positions of the outer wall, and reinforcing ribs 42 connecting the two reinforcing rings 41. The reinforcing rings 41 at two ends are connected through the reinforcing convex ribs 42, so that the reinforcing rings, the reinforcing convex ribs 42 and the reinforcing rings 41 are connected into a whole, the reinforcing convex ribs 42 support the two reinforcing rings 41, and the whole structural strength is stronger.
The reinforcing ribs 42 are of an X-shaped structure, and are arranged in a plurality and arranged along the circumferential direction. The X-shaped structure is connected with the two reinforcing rings 41 to form an upper triangle and a lower triangle, and the triangle has the advantage of strong stability, so that the reinforcing ribs can have stronger supporting force on the two reinforcing rings 41.
A plurality of through holes 5 are formed in the body 1 along the circumferential equal distance, and a circle of dustproof ring 6 is arranged outside each through hole. The dustproof ring 6 can play a role in retaining water and dust, so that the openings at the two axial ends of the through hole 5 are sealed with the contact part through the dustproof ring 6, and external dust or moisture is prevented from entering the through hole.
