Abstract
Provided is a simple abrasion-resistant seal ring. The seal ring comprises a seal ring body, a base body of the seal ring body is formed by cast iron or a steel structure at one time, a section is formed in the base body of the seal ring, meanwhile a layer of abrasion-resistant ceramic coats the surface of the base body, and an abrasion pattern belt is formed on the surface of an abrasion-resistant ceramic material coating. In addition, a layer of graphite coating is stamped on an outer layer of the abrasion-resistant ceramic material coating. The simple abrasion-resistant seal ring is simple in technology, convenient to process, easy to assemble, and capable of improving the seal effect while effectively reducing abrasion of the contact position of the seal ring and a shaft.
Description
Technical field
The utility model relates to mechanical sealing element, is specially the wear-resistant seal ring of a kind of simple type.
Background technique
In general, in numerous seal means of field of sealing technology, adopt seal ring that axle spare is sealed very general, existing seal ring is various, makes but mostly be greatly cast iron, weight is heavier and cost of production is higher, processed complex, for the frequent axle spare that need to slide, need to apply lubricant method, even and adopt lubricant method, also can due to when work oil ring self inertia large, energy consumption is larger, causes seal wears speed to be accelerated; Under this condition, also have and use graphite material to prepare seal ring, its quality is soft, corrosion-resistant, preparation cost is cheap, does not need extra lubricant method when connecting slider, simultaneously, only need less pretightening force just can realize sealing effect, but this graphite-seal ring also exists defective, and itself property is crisp, can't bear too high face and press and cause anchor ring wearing and tearing, pressure break, until seal action was lost efficacy.
The model utility content
The technical problem that the utility model solves is to provide a kind of simple type wear-resistant seal ring, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The wear-resistant seal ring of a kind of simple type, comprise the seal ring body, the matrix of its seal ring body is that cast iron or steel structure material once-through are made, and have a section on the anchor ring of its matrix, simultaneously, scribble one deck wear-resistant ceramic on the surface of described matrix, the surface of this wear-resistant ceramic material coating has friction decorative pattern band, in addition, the skin of this wear-resistant ceramic material coating also punching press one deck graphite coating is arranged.
In the utility model, the ratio of the thickness of described matrix, abrasion-proof ceramic coat and graphite coating is 5:2:1.
In the utility model, the end face width of described matrix is 1 ~ 3mm.
Beneficial effect: the utility model is simple in structure, fabricating cost is cheap, the outer wear-resistant ceramic material coating that adopts of its metallic matrix improves its wear-resisting property, the outer graphite layer that adopts is as self lubricating material, and the friction decorative pattern band that has on the wear-resistant ceramic material coating can facilitate the graphite coating moulding on the one hand, on the other hand can graphite coating long-time use come off after fastening connection piece, and utilize the powdered graphite that remains in friction decorative pattern band to alleviate seal ring also to have increased sealing effect simultaneously with the wearing and tearing of touching the position that are coupling.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Fig. 2 is the tangent plane schematic diagram on the ring plate of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to the wear-resistant seal ring of a kind of simple type of Fig. 1, Fig. 2 in the present embodiment, comprises seal ring body 5, is provided with a section 6 on the anchor ring of this seal ring body 5, the vertical shearing section of this end face.
Simultaneously, in the present embodiment, the matrix 4 of seal ring body 5 is made for the Steel material once-through, the skin of this matrix 4 is provided with one deck wear-resistant ceramic material coating 3 and one deck graphite coating 1, and also have friction decorative pattern band 2 between wear-resistant ceramic material coating 3 and graphite coating 1 on the surface of contact of wear-resistant ceramic material coating 3, this friction decorative pattern band 2 can facilitate the graphite coating moulding on the one hand, on the other hand can graphite coating long-time use come off after fastening connection piece, alleviated seal ring and also increased sealing effect simultaneously with the wearing and tearing of touching the position that are coupling.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. wear-resistant seal ring of simple type, comprise the seal ring body, it is characterized in that, the matrix of seal ring body is cast iron or steel structure material once-through, and has a section on the anchor ring of this matrix, simultaneously, scribble one deck wear-resistant ceramic on the surface of described matrix, the surface of this wear-resistant ceramic material coating has friction decorative pattern band, in addition, the skin of this wear-resistant ceramic material coating also punching press one deck graphite coating is arranged.
