Feature can express or implicitly include one or more this feature.In the description of the invention, unless separately
It is described, " multiple " are meant that two or more.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the invention
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of high voltage bearing axis hole double-purpose sealing ring, as depicted in figs. 1 and 2, include the matrix 1 of cyclic structure, in matrix 1
Side is provided with seal lip 2, and opposite side is reserved with the first seal groove 3 for mounting O-shaped sealing ring；The inwall of described matrix 1 is pre-
The second seal groove 4 is left, becket 5 is provided with close to the position provided with the first seal groove in the inwall of matrix 1；The seal lip 2
U-shaped structure.Matrix is rubber matrix, it is preferred to use oil resistant rubber.
The first seal groove 3 for mounting O-shaped sealing ring is reserved with the side of matrix 1, can be as needed, utilizing
When this sealing ring is sealed different from the end face provided with the side of lip 2 (for example use this sealing ring and other seal combinations
When, it is not provided with the side of lip 2 using this sealing ring and is bonded with other seals, collectively forms knockdown sealed construction), can
It is very convenient and practical to install O-ring seal in first seal groove 3, it ensure that between the seal assembly being applied in combination
Sealing.
The second seal groove 4 is reserved with the inwall of matrix 1, when for sealing, can be pacified in second seal groove
Corresponding seal (such as O-ring seal) is filled, forms combined seal structure, using the seal in the second seal groove and originally
The lip of sealing ring, dual sealing functions can be played, sealing effectiveness is splendid, even if after long-term use, changing the second seal groove 4
Interior seal, i.e., sealing effectiveness can be preferably ensured, without sealing ring main body (matrix is together with becket) is changed, saved
Material, practical cost is saved, reduce the difficulty for changing seal operation.
Overall above-mentioned first seal groove 3 is in dove-tail form structure, and its groove width gradually increases from aperture position to bottom land.It is such a close
The structure design of groove is sealed, effectively avoids seal from departing from out of seal groove.In addition, in order to ensure that seal coordinates with seal groove
Closely, reliable sealing is realized, seal vulcanization when installing seal, can be bonded in the seal groove of insert body blind end
It is interior.
Generally, groove width of above-mentioned first seal groove 3 close to bottom land position is the 1.2-1.5 of the groove width close to aperture position
Times.Under this width ratio, it can preferably ensure full first seal groove 3 of seal (the being usually O-ring) filling that is squeezed,
Resistance to overturning is more preferable, and sealing is reliable.Will not be excessive because of slot bottom width, seal is integrally squeezed into the first sealing after being pressurized
Groove, influence sealing.
Above-mentioned becket 5 uses copper ring, and its thickness is 3-8mm, width 10-15mm.Generally, becket one end is not with setting
It is concordant to put the side end face of lip one, i.e., becket 5 is arranged on matrix inwall from matrix side, and matrix inwall is used to install becket
Position be provided with groove 6, the becket after installation is consistent with matrix inwall internal diameter.Matrix seals, and becket
Splendid support positioning action can be played, certain wear-resistant protective action is formed to matrix, further, it is possible to suitable for height
It is long-term use of under speed, severe duty, the premature abrasion of sealing ring will not also occur.
The outer wall surface of above-mentioned matrix 1 is provided with wearing layer.Generally, wearing layer includes what is be interwoven by some singles
Wear-resisting net and the wear-resisting glue oar coated on the net.
The invention is compact-sized, and anti-pressure ability is strong, can adapt under high pressure, high speed, the operating mode of heavy duty, has splendid
Sealability, can be used with other seal combinations, reach good sealing effectiveness.Meanwhile this sealing ring can both be made
Use, can also be used as hole seal, versatility is very good for shaft seal.
The preferred embodiment of the invention is the foregoing is only, is not intended to limit the invention creation, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc., the invention should be included in
Protection domain within.
