Abstract
The utility model provides a kind of bottom shell sealing pad of engine oil, belongs to technical field of sealing technology.It solves the problem of easy oil leak of existing bottom-end gasket, poor sealing.This bottom shell sealing pad of engine oil includes shim body, big cylinder-bore there are one being opened up in the middle part of shim body, one circle rubber bound edge is installed on the internal perisporium of shim body, the outboard end of rubber bound edge has two positive stop strips in conjunction, the limiting slot of two positive stop strips insertion is supplied there are two being opened up in shim body respectively, it is provided with a magnetic soft item of metal of tool between rubber bound edge and the inner wall of shim body, annular groove of the circle for the soft item insertion of metal is offered on the inner wall of rubber bound edge.The utility model, which has, to be unlikely to deform, the good advantage of sealing effect.
Description
Technical field
The utility model belongs to technical field of sealing technology, is related to the sealing of engine, more particularly to a kind of engine sump tank
Gasket.
Background technology
Engine sump tank is the lower half of crankcase, also known as lower crankcase.Effect is closed crankcase as store oil
The shell of slot, and the lubricating oil flowed back to by each friction surface of diesel engine is collected and stores, partial heat is dispersed, lubricating oil oxygen is prevented
Change.Gasket is usually required between engine sump tank and engine body to be sealed.
Gasket is shaped by the vulcanization of rubber used in oil sump traditional at present, and material only has rubber one kind, is used for
The sealing that oil sump is connect with engine cylinder body bottom surface.Pure rubber material oil sump pad is relatively soft, has certain elasticity, in oil sump
The deflection of oil sump pad toward surrounding is inconsistent caused by pure rubber oil sump pad is without positioning and support during pad press fitting, usually
By toward the position distortions for being easy to its extension when rubber extruded, because resistance is small on engine left and right directions, direction deformation is easily caused
Greatly, oil sump is caused to pad oil leak if the big support plane to more than oil sump bottom surface of deformation, oil leak may seriously cause to start
Machine scuffing of cylinder bore, tile kilning.
Invention content
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, provides one kind and is unlikely to deform, close
Seal the good bottom shell sealing pad of engine oil of effect.
The purpose of this utility model can be realized by following technical proposal：A kind of bottom shell sealing pad of engine oil, including
Shim body, opens up that there are one big cylinder-bores in the middle part of the shim body, which is characterized in that the shim body it is interior
One circle rubber bound edge is installed, the outboard end of rubber bound edge has two positive stop strips in conjunction, the pad on peripheral wall
The limiting slot of two positive stop strips insertion, the inner wall of the rubber bound edge and shim body are supplied there are two being opened up on piece ontology respectively
Between be provided with a magnetic soft item of metal of tool, it is embedding for the soft item of metal to offer a circle on the inner wall of the rubber bound edge
The annular groove entered.
In a kind of above-mentioned bottom shell sealing pad of engine oil, the shim body is by aluminum base plate and two panels asbestos paper
Piece forms, and the two panels asbestos scraps of paper are bonding on the upper and lower surface of aluminum base plate respectively.
In a kind of above-mentioned bottom shell sealing pad of engine oil, the inner end of the rubber bound edge has the two of upper lower convexity
A sealing lip.
In a kind of above-mentioned bottom shell sealing pad of engine oil, described two positive stop strips are diagonal distribution.
Compared with prior art, this bottom shell sealing pad of engine oil has the following advantages：
1, shim body is made of aluminum base plate and the two panels asbestos scraps of paper, and asbestos paper has good heat-resisting and rotproofness,
The heat at engine cylinder body has been obstructed well, is prevented aluminum base plate from deforming, is ensured its sealing performance；
2, the soft item of magnetic metal being arranged between rubber bound edge and the inner wall of shim body, can be by the metal in fuel oil
In impurity absorption to rubber bound edge, cylinder and piston ring are protected, while fuel oil being promoted fully to burn, improves the dynamic of engine
Power performance；
3, two positive stop strips diagonally designed are additionally arranged on rubber bound edge, positive stop strip is caught in pad by rubber bound edge in assembly
In the limiting slot of piece ontology so that rubber bound edge is mounted in shim body more securely, prevents the rubber bag length of side time from using
After be detached from.

Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, Figure 2, Figure 3 shows, this bottom shell sealing pad of engine oil includes shim body 1, and the middle part of shim body 1 is opened
If there are one big cylinder-bore 2, a circle rubber bound edge 3, the outboard end of rubber bound edge 3 are installed on the internal perisporium of shim body 1
Positive stop strips 4 in conjunction two diagonal distribution designs, open up that there are two supply two positive stop strips respectively in shim body 1
The limiting slot 5 of 4 insertions is provided with a magnetic soft item 6 of metal of tool, gold between rubber bound edge 3 and the inner wall of shim body 1
It is pole shape to belong to soft item 6, and the annular groove 7 that a circle is embedded in for the soft item 6 of metal, annular groove 7 are offered on the inner wall of rubber bound edge 3
Opening be less than the diameter of the soft item of metal 6, the inner end of rubber bound edge 3 has two sealing lips 8 of upper lower convexity, shim body 1
It is made of aluminum base plate 10 and the two panels asbestos scraps of paper 9, the two panels asbestos scraps of paper 9 are bonding on the upper and lower surface of aluminum base plate 10 respectively.
