Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention; for convenience of description, in the present application, "left side" is "first end", "right side" is "second end", "upper side" is "first end", and "lower side" is "second end" in the current view, so that the description is for the purpose of clearly expressing the technical solution, and should not be construed as an improper limitation to the technical solution of the present application.

The product that this technical scheme provided is a modification cylinder gasket, mainly includes first functional layer 11, second functional layer 22, and the material is SUS301 stainless steel, and the spacing layer material is SUS304 stainless steel, in addition with the material of distance layer by the tinplate replacement SUS304 stainless steel; the cylinder opening sealing rib is in a full-corrugated structure, and the peripheral sealing rib is in a half-corrugated structure formed by half-corrugated ribs and rigid limiting ribs.

The modified cylinder gasket has the advantages that under the condition of ensuring the corrugated sealing force, the actual comprehensive hardness can reach 104HRB, the problem of leakage of oil return holes at the air inlet side and the air exhaust side under the working of an engine is avoided, the price of the modified cylinder gasket is almost the same as that of a tin plate material, and the material cost cannot be increased; and the manufacturing process step is changed into the steps of blanking of the lower piece → pressing of the lower piece for limiting the rib → pressing of the lower piece for rib, and the steps are completed.

The rigidity limiting rib of the cylinder gasket designed originally has high supporting strength and low distance layer hardness, the distance layer is obviously imprinted after the experiment, the height of the rigidity limiting rib of the cylinder gasket is reduced under the work of an engine, the sealing capability is lost, and the positions of oil return holes on the air inlet side and the air outlet side are leaked; through the design of the technical scheme, the comprehensive hardness is obviously improved, the situation that the height of the rigid limiting rib is reduced under the working condition of an engine is prevented, the sealing capability of the rigid limiting rib is ensured, and the problem of leakage of the air inlet side, the air exhaust side and an oil return hole of the engine is solved; the specific technical scheme is as follows: referring to fig. 1, 2 and 3, the modified cylinder gasket includes an assembly body 10, the assembly body 10 has a distance layer portion adapted to the shape of the assembly body 10; a full-corrugated structure 100 provided at the cylinder port 1 seal rib; a half-bellows structure 200 formed at the periphery of the cylinder port 1 and the edge of the assembly body 10; and a rigid stopper rib 300 disposed at the first coupling position and the second sealing position of the assembly body 10.
