Abstract

The utility model relates to a rotary sealing element, an inner ring of which is conical surface, the surface of the conical surface is provided with biradial tenuous grains. When two rotary sealing elements are used relatively, because of the action of centrifugal force, scouring force of lubricating oil towards edges of bright bands is increased, thereby reducing condensation of plastic in the lubricating oil on the edges of the bright bands, and contributing to the radiation of the bright bands; meanwhile, impact force of the lubricating oil contributes to the penetration of the lubricating oil between two bright bands, lubricating property between the two rotary sealing elements is improved, thereby improving the quality of the rotary sealing element, increasing the service life of the rotary sealing element. The utility model has the advantages of good lubricating effect, good radiating, abrasion prevention, long service life, high quality, convenient processing and low cost.

Description

Rotating seal

Technical field

The utility model belongs to seal ring, particularly relates to the rotating seal of a kind of high lubricating effect, good heat dissipation.

Background technique

As everyone knows, rotating seal large end face place is made up of two-part usually, and the inner lane of annular surface is the sphere band, and the outer ring is that bright band is a sealing strip, and its lubrication effect is poor, and it is bad to dispel the heat, quick abrasion, and working life is short, and is of poor quality.

Summary of the invention

The utility model provides a kind of high lubricating effect, good heat dissipation and quality high rotating seal for solving the technical problem that exists in the known technology.

The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it comprises cambered surface band and bright band, it is characterized in that: the inner lane of rotating seal is the conical surface, with ° 30 '-3 ° 30 ' of plane included angle α=1, the surface of the conical surface has the fine lines of biradial shape, and 2.5mm place, its outer ring is a bright band.

Advantage and the good effect that the utlity model has are: high lubricating effect, and good heat dissipation, not easy to wear, long service life, the quality height is convenient to processing, and cost is low.

Description of drawings

Fig. 1 is the structural representation of rotating seal;

Fig. 2 is that schematic representation is looked on the left side of Fig. 1.

Among Fig. 1, Fig. 2: 1. rotating seal, the 2. conical surface, 3. bright band.

Embodiment:

For further understanding summary of the invention of the present utility model, characteristics and effect, following examples for example, and conjunction with figs. now are described in detail as follows, and see also Fig. 1, Fig. 2.

As shown in Figure 1 and Figure 2: the inner lane of rotating seal 1 is the conical surface 2, and with ° 30 '-3 ° 30 ' of plane included angle α=1, the surface roughness of the conical surface 2 is≤1.6 μ m, and the surface has the fine lines of biradial shape, and 2.5mm place, its outer ring is a sealing strip for bright band 3.When two rotating seals 1 use relatively, in operation process,, increased the scouring force of lubricant oil to bright band 3 edges owing to action of centrifugal force, thereby, reduced colloidal material in the lubricant oil the condensing of bright band 3 edges, it helps the heat radiation of bright band 3, simultaneously, the impact force of lubricant oil, help the brill of lubricant oil between two bright bands 3 and ooze, improved the greasy property between two rotating seals 1, therefore, improve the quality of rotating seal 1, increased working life.

Its advantage is: high lubricating effect, and good heat dissipation, not easy to wear, long service life, the quality height is convenient to Processing, cost is low.
