Abstract
The utility model discloses a kind of vibration damping gasket seals, comprising: metal inner cord；First NBR middle layer and the 2nd NBR middle layer, the first NBR middle layer and the 2nd NBR middle layer are separately positioned on the two sides of metal inner cord；And first foaming NBR outer layer and the second foaming NBR outer layer, the first foaming NBR outer layer and the second foaming NBR outer layer be separately positioned on the outside of the first NBR middle layer and the 2nd NBR middle layer；Wherein, the thickness of the first NBR middle layer and the 2nd NBR middle layer is equal, and the thickness of the first foaming NBR outer layer and the second foaming NBR outer layer is equal.Vibration can be effectively relieved in the vibration damping gasket seal of the utility model, and sealing effect is good.
Description
Technical field
The utility model is about a kind of gasket, especially with regard to a kind of vibration damping gasket seal.
Background technique
Gasket is the mechanical seal between two objects, usually to prevent from being under pressure between two objects, burn into and
Pipeline expands with heat and contract with cold leakage naturally.Gasket is usually made of flaky material, such as packing paper, rubber, silicon rubber, metal, cork, hair
Felt, neoprene, nitrile rubber (NBR), glass fibre or plastic polymer (such as polytetrafluoroethylene (PTFE)).At present engine (including
Diesel engine, gasoline engine and other kinds of internal combustion engine) its power density all is being improved, however as the raising of engine power,
The vibration of engine itself will be higher and higher, when the tolerance range that engine luggine is more than bolt will lead to bolt fracture.
Traditional gasket has metal gasket, without asbestos washer etc., and due to the limitation of gasket material and thickness, these gaskets are only
The effect of sealing can be played, the effect for alleviating vibration can not be played.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
Utility model content
The purpose of this utility model is to provide a kind of vibration damping gasket seal, vibration can be effectively relieved, and seal effect
Fruit is good.
To achieve the above object, the utility model provides a kind of vibration damping gasket seal, comprising: metal inner cord；First
NBR middle layer and the 2nd NBR middle layer, the first NBR middle layer and the 2nd NBR middle layer are separately positioned on the two of metal inner cord
Side；And first foaming NBR outer layer and second foaming NBR outer layer, first foaming NBR outer layer and second foaming NBR outer layer difference
The outside of first NBR middle layer and the 2nd NBR middle layer is set；Wherein, the first NBR middle layer and the 2nd NBR middle layer
Thickness is equal, and the thickness of the first foaming NBR outer layer and the second foaming NBR outer layer is equal.
In a preferred embodiment, metal inner cord with a thickness of 0.25mm.
In a preferred embodiment, the first NBR middle layer and the 2nd NBR middle layer with a thickness of 1~1.35mm.
In a preferred embodiment, vibration damping gasket seal with a thickness of 3.2 ± 0.32mm.
In a preferred embodiment, the first NBR middle layer and the 2nd NBR middle layer with a thickness of 1mm.
In a preferred embodiment, the first NBR middle layer is logical with metal inner cord and the first foaming NBR outer layer respectively
Adhesive bond is crossed, the 2nd NBR middle layer passes through adhesive bond with metal inner cord and the second foaming NBR outer layer respectively.
Compared with prior art, vibration damping gasket seal according to the present utility model has the advantages that the utility model
Gasket is made of two layers of foaming NBR, two layers of NBR and one layer of metal plate；First foaming NBR outer layer and the second foaming NBR outer layer energy
Enough effectively to play sealing function, the first NBR middle layer and the 2nd NBR middle layer can effectively alleviate vibration, thus effectively
Reduce bolt bring relevant issues affected by vibration.
Detailed description of the invention
