Abstract
The utility model discloses one kind from tight seal washer, limit sleeve, Elasticity by rubber seal and positioned at its medial and lateral are constituted, three lower end surface flushes, Elasticity upper surface is lower than limit sleeve upper surface, difference a=0.1~3mm, there is opening on Elasticity, width is 0 <b≤1mm.The utility model is sealed for bolt mounting surface air-liquid body, can limit the radial dilatation of rubber seal, so that its both ends of the surface is generated additional axial additional facet pressure, is enhanced sealing effect, and persistently reliable sealing is reached.
Description
Technical field
The utility model relates to the containment members in Automatic manual transmission, especially a kind of close for bolt mounting surface air-liquid body
Envelope from tight seal washer.
Background technique
Have high requirements in many electromechanical equipments, especially diesel engine, constructional engineering machinery to air-liquid sealing, usual feelings
Copper gasket, aluminium washer or bonded washer sealing under condition at hinged hollow bolt mounting surface using single material.These washers exist
After mechanically installing and compressing, in use, due to repeated actions such as high/low temperature, sunshine, vibrations, sealing material can be generated
It is creep, loose, resilience is gradually lost, sealing surface face pressure reduces, and makes seal failure.
Utility model content
The purpose of the utility model is to overcome the deficiency of the prior art, propose that a kind of face pressure for making sealing surface is mended
Repay, reach persistently reliably seal from tight seal washer.
The utility model is achieved through the following technical solutions technical purpose.
From tight seal washer, including rubber seal and positioned at the limit sleeve of inside, improvements are close in rubber
The Elasticity with opening, the lower end surface of the limit sleeve, the lower end surface of Elasticity and rubber seal are equipped on the outside of seal
Lower end surface flush, the upper surface of Elasticity is lower than the upper surface of limit sleeve.
Further embodiment is the opening width of the Elasticity are as follows: 0 <b≤1mm；The Elasticity upper surface is low
Difference a=0.1~3mm in limit sleeve upper surface；The limit sleeve and Elasticity are metal material.
Using the above structure, the principles of the present invention and beneficial effect are: limit sleeve plays limit after bolt presses
Effect, controls the compression ratio of rubber seal, it is made effectively to play sealing function.So-called compression ratio is the compression of rubber seal
The ratio of amount and its thickness is 15%~30% by static seal control range requirement.Elasticity enduringly banding positioned at outside
Rubber seal limits it to radial dilatation, and so that rubber seal both ends of the surface is generated additional axial direction and add face pressure, enhances close
Seal effect.Opening on Elasticity is automatically adjusted with the change of decrement, and the face pressure of sealing surface is made to be equalized compensation,
Reach persistently reliable sealing.Opening width is preferably within 1mm, and otherwise rubber ring can generate local deformation, influences sealing effect.
The Elasticity upper surface is lower than limit sleeve upper surface, keeps an evacuation gap after making bolt presses, avoids Elasticity
It is crushed to death, influences its normal work.Difference in height a is preferably 1~3mm, and a is too small to will affect cranse automatic adjustment, and a is too big to make rubber
It is extended out at the top of cushion rubber, reduces additional face pressure, generate creep, influence sealing effect.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
Refering to attached drawing, from tight seal washer by rubber seal 1, positioned at the limit sleeve 2 of inside and positioned at the band in outside
The Elasticity 3 of opening is constituted, and three lower end surface flushes, and upper surface is in step, the control of rubber seal decrement for 20~
25%, Elasticity upper surface is lower than the difference a=2mm, opening width b=0.5mm of Elasticity of limit sleeve upper surface.Limit
Set uses A3 steel, and Elasticity uses spring steel 65Mn.
Claims (4)
1. one kind is from tight seal washer, including rubber seal and positioned at the limit sleeve of inside, it is characterized in that in rubber seal
Circle outside is equipped with the Elasticity that band is open, the lower end surface of the limit sleeve, the lower end surface of Elasticity and rubber seal
Lower end surface flushes, and the upper surface of Elasticity is lower than the upper surface of limit sleeve.
2. according to claim 1 from tight seal washer, it is characterised in that: the opening width of the Elasticity are as follows: 0 <b
≤1mm。
3. according to claim 1 from tight seal washer, it is characterised in that: the Elasticity upper surface is lower than limit sleeve
Difference a=0.1~3mm of upper surface.
4. according to claim 1 from tight seal washer, it is characterised in that: the limit sleeve is metal material with Elasticity
Matter.
