Summary of the invention
Technical problem to be solved in the utility model provides a kind of rational in infrastructure, uniform cylinder seal pad of good seal performance, stress distribution.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of cylinder seal pad, comprise sealing gasket body, described sealing gasket body has cylinder-bore, it is characterized in that: described sealing gasket body is formed by stacking in order by four layers of metallic shim, the surrounding wherein the upper strata pad of the superiors and the underlying shim of the bottom being positioned at cylinder-bore is provided with projection, the edge that third layer pad is being positioned at cylinder-bore is provided with kink, the bore edges being coated on second layer pad after the turnover of this kink forms turnover bound edge, the annular groove of inserting for turnover bound edge is provided with at the bore edges upper surface of second layer pad, the position corresponding to annular groove at the bore edges lower surface of second layer pad is provided with annular convex ring.
As improvement, after described turnover bound edge turnover, be positioned at the position of the projection of upper strata pad.
As improvement, the height of described annular groove and the consistency of thickness of third layer pad, after described turnover bound edge turnover and the surface of second layer pad flushes.
As improvement, the height of described annular convex ring is 0.06mm.
As improvement, described upper strata pad is identical with the thickness of underlying shim, is 0.2 ~ 0.3mm, and the thickness of second layer pad is 0.8 ~ 1.2mm, and the thickness of third layer pad is 0.11 ~ 0.13mm.
Improve, the thickness of described upper strata pad and underlying shim is 0.25mm again, and the thickness of second layer pad is 1.0mm, and the thickness of third layer pad is 0.12mm.
Improve, described cylinder-bore is four that distribute side by side successively, and described sealing gasket body is also provided with the cooling water hole corresponding with cylinder, push-rod hole, oilhole and bolt positioning hole again.
Further improvement, the edge of described cooling water hole, push-rod hole, oilhole is respectively equipped with the metal retainer therefor for increasing intensity.
Further improvement, the position described upper strata pad corresponding to bolt positioning hole is provided with inner fovea part.
Compared with prior art, the utility model has the advantage of: adopt four layers of metallic shim to be formed by stacking, not only intensity is good, and detachable replacing, manufacture processing and installation are all very convenient; The thickness of second layer pad is maximum, and third layer pad is the thinnest, and the surrounding that upper strata pad and underlying shim are positioned at cylinder-bore is provided with projection, third layer pad is provided with turnover bound edge by coated for second layer pad, not only stress distribution is even, also effectively prevent cylinder mouth and collaborates, but also add sealing; In addition, be provided with metal retainer therefor at the edge in each hole of sealing gasket body, further increase sealability.The utility model is rational in infrastructure, good seal performance, stress distribution are even, and can support the use with the motor in multiple field such as automobile, engineering machinery, boats and ships, generating, alternative imported product, has broad application prospects.
