Abstract
The utility model discloses a sealing ring which is a rubber integrated piece. The sealing ring comprises an annular plate-shaped body and a central hole which share an axial line. The two sides of the inner wall of the central hole are respectively provided with a sealing line extending and protruding in the center direction. A groove used for parting manufacturing is formed between the two sealing lines, and the sealing lines and the groove are in smooth transition. The two faces of the annular plate-shaped body are respectively provided with three rings of U-shaped rings concaved inwards, and the U-shaped rings are filled with silicone grease. The sealing ring is good in sealing effect, reasonable in structure, skillful in design and high in market promotional value, the parting face of a die in the manufacturing process is located on the groove between the two sealing lines, and small gaps where leakage occurs easily cannot be formed between burrs on the parting face and a shaft easily.
Description
Technical field
The utility model relates to caulking gum field, and being specifically has radial seal requirement to carry out the seal ring of architecture advances to center hole.
Background technique
The effect of seal ring is mainly for preventing leakage and the foreign object intrusion of liquid state or gaseous substance, having reached the airtight effect of sealing.General seal ring simple designs is plantation rubber ring flat-plate shape, seal ring is suppressed out by mould process, in manufacture process, seal ring center bore inner wall is because the reason of mold joint easily produces burr burr, install after utilization, burr burr is clipped between axle and seal ring center bore inner wall, because the more difficult thorough removing of burr burr is clean, between axle and seal ring inwall, produce a lot of small gap, liquid or gaseous matter leak or seepage from gap, foreign object is also easier to invade simultaneously, causes seal failure.And be difficult for detecting when leakproof detects, maintenance difficulty is increased greatly.Therefore for the problems referred to above, are objects of the utility model research.
Model utility content
The purpose of this utility model is to provide a kind of seal ring, sealing circle good sealing effect, mold parting surface in manufacture process is on the groove between two potted lines, burr on mold joint be difficult for and axle between form the small gap of easily leaking, rational in infrastructure, design ingeniously, there is market popularization value very widely.
The technical solution of the utility model is: a kind of seal ring, seal ring is rubber integral piece, the Circular Plate shape main body and the center hole that comprise coaxial line, described center bore inner wall both sides are respectively provided with one and extend to central direction the potted line protruding, between two potted lines, form a groove of manufacturing for somatotype, rounding off between described potted line and groove, described Circular Plate shape main body is respectively provided with the U-shaped circle that three circles cave in inwards on two sides, and the U-shaped circle that is positioned at inner ring and outer ring is filled with silicone grease.
In order to make sealing circle have good resistance to heat, the material of described Circular Plate shape main body is SIL silicone rubber.
The utility model has the advantage of: sealing circle good sealing effect, the mold parting surface in manufacture process is on the groove between two potted lines, and working surface is separated with mold joint.Utilize dexterously that rubber plasticity is large, the processing characteristics of good springiness, product can be deviate from by force in mould, utilized again the elastic memory of rubber material to guarantee that the product size of producing meets seal request simultaneously.In manufacture process, burr mainly concentrates on groove, and rotating shaft and two potted lines are directly closely tied tight, burr on mold joint be difficult for and axle between form the small gap of easily leaking, thereby avoided the seal failure that causes due to mold joint burr burr; Be designed with three circle U-shaped circles, wherein in the U-shaped circle of inner ring and outer ring, be filled with silicone grease, the U-shaped circle of inner ring and outer ring tightly holds the link end face of required sealing, forms the isolation features of sucker-type, make sealing circle there is very strong sealing effect, antileaking leakage of oil; Rational in infrastructure, design ingeniously, there is market popularization value very widely.

Fig. 2 is the seal ring plan structure schematic diagram in embodiment.
Label declaration: 1-silicone grease 2-Circular Plate shape main body 3-U shape circle 4-potted line 5-groove 6-center hole 7-mold parting surface.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
With reference to legend 1 ~ 2, a kind of seal ring, seal ring is rubber integral piece, the Circular Plate shape main body 2 and 6 holes, center that comprise coaxial line, described center hole 6 inwall both sides are respectively provided with between potted line 4, two potted lines 4 that protrude to central direction extension and form a groove 5 of manufacturing for somatotype, rounding off between described potted line 4 and groove 5, described Circular Plate shape main body is respectively provided with the U-shaped circle 3 that three circles cave in inwards on 2 two sides, and the U-shaped circle 3 that is positioned at inner ring and outer ring is filled with silicone grease.Sealing circle good sealing effect, mold parting surface 7 in manufacture process is on the groove 5 between two potted lines 4, and in manufacture process, burr mainly concentrates on groove 5, rotating shaft and two potted lines 4 are directly closely tied tight, burr on mold joint be difficult for and axle between form the small gap of easily leaking.Be designed with three circle U-shaped circles 3, wherein in the U-shaped circle 3 of inner ring and outer ring, be filled with silicone grease 1, the U-shaped circle 3 of inner ring and outer ring tightly holds the link end face of required sealing, forms the isolation features of sucker-type, make sealing circle there is very strong sealing effect, antileaking leakage of oil.
In order to make sealing circle have good resistance to heat, the material of described Circular Plate shape main body 2 is SIL silicone rubber.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (2)
1. a seal ring, seal ring is rubber integral piece, the Circular Plate shape main body and the center hole that comprise coaxial line, it is characterized in that: described center bore inner wall both sides are respectively provided with one and extend to central direction the potted line protruding, between two potted lines, form a groove of manufacturing for somatotype, rounding off between described potted line and groove, described Circular Plate shape main body is respectively provided with the U-shaped circle that three circles cave in inwards on two sides, and the U-shaped circle that is positioned at inner ring and outer ring is filled with silicone grease.
