Abstract
The utility model discloses a metal flat gasket and relates to the technical field of machine parts. The metal flat gasket comprises a cylinder cover liner, cylinder head bolt holes, through holes, combustion chambers, compression limiting blocks, small holes, and a gasket hole, wherein a plurality of the cylinder head bolt holes are symmetrically arranged at two ends of the cylinder cover liner, a plurality of the combustion chambers are evenly arranged on the cylinder cover liner, the through holes are formed in lower ends of the combustion chambers, the compression limiting blocks are arranged at edges of the combustion chambers, a plurality of the small holes are evenly formed in outer sides of the combustion chambers, and the gasket hole is formed in one side of the cylinder cover liner. According to the metal flat gasket, the structure is reasonably designed, linear load on ripples is high, contact pressure is more evenly distributed, better load distribution can be obtained in a wider limiting area, deformation of a cylinder sleeve is reduced, the thickness of a limiting layer is small so that deformation of parts of an engine is smaller, wider ripples can be suitable for narrower lintels, and fatigue properties of the gasket are improved.
Description
Technical field
The utility model relates to a kind of flat metallic gasket, belongs to mechanical fitting technical field.
Background technique
Flat metallic gasket is made up through machining of bulk metal, for the sealing at the positions such as pressurized container, tower, groove, valve gap.Mainly contain aluminium plain cushion, red copper pad, stainless steel pad.For preventing that the interior medias such as pipe container from having bolt flange connection part to use to outward leakage, fitted bolt flange produces the product of position between two flanges mostly of sealing effect, is called pad; If find pad standard from this angle, great majority are that nonmetallic gasket is just called as flat gasket, and the pad of complete metal is seldom used to such sealing configuration.Existing flat metallic gasket structural design is reasonable not, processed complex, and expensive, sealing effect is poor, and contact distributes even not, can not meet people's user demand.
Model utility content
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of flat metallic gasket.
Flat metallic gasket of the present utility model, it comprises cylinder head gasket, cylinder head stud hole, through hole, firing chamber, compression limiting stopper, aperture, pad perforate, on cylinder head gasket, two ends are symmetrically arranged with several cylinder head studs hole, on cylinder head gasket, be evenly provided with several firing chambers, the lower end of firing chamber 4 is provided with through hole, the edge of firing chamber is provided with compression limiting stopper, and the outside of firing chamber is evenly provided with several apertures, and a side of cylinder head gasket is provided with pad perforate.
As preferably, described cylinder head gasket is made up of the first functional layer, mesosphere and the second functional layer, between the first functional layer and the second functional layer, is provided with mesosphere.
As preferably, the first described functional layer and the surface of the second functional layer are coated with elastomeric material coating, and this coating can be strengthened the sealing area of freezing mixture or oil.
As preferably, described mesosphere adopts spring steel to make, and can provide extra sealing effect for pad.
As preferably, the periphery in described cylinder head stud hole is provided with sealing ripple.
As preferably, described pad perforate is mainly used to hold the overhead camshaft of chain wheel drive.
The beneficial effects of the utility model: its reasonable in design, linear load on ripple is high, contact is more evenly distributed, wider stop zone, can obtain good load and distribute, and reduces cylinder-liner distortion amount, spacing layer thickness is thin, can make engine part distortion less, wider ripple, applicable to the narrower beam width of crossing, improves the fatigue behaviour of pad.
