Abstract
The utility model relates to a metal air cylinder gasket in the structure of a single-layer riveting type rubber ring, which solves the problems that the present asbestos composite-type air cylinder gasket is easily aged and is not friendly to environment, the thickness is not constant, the impact on the engine performance is great, and the reliability of sealing water as well as oil sealing is poor. The gasket comprises a gasket body. A cylinder mouth, a water-oil hole, a bolt hole and a positioning hole are arranged on the gasket body. The special points of the gasket are as follows: the gasket body adopts a single-layer metal plate, a metal ring is arranged at the position of the cylinder mouth, the metal ring is riveted with the single-layer metal plate, and a ring-shaped corrugated rib is arranged on the surface of the metal ring; the metal ring and the single-layer metal plate have different thickness, which leads thickness difference; a ring-shaped metal framework is welded on the gasket body correspondingly to the position of the water-oil hole, and the rubber ring is arranged at the inner rim of the metal framework. The metal air cylinder gasket has the advantages that: the metal air cylinder gasket can ensure constant thickness and pressure value of materials, and can greatly improve the reliability of air sealing; the rebound elasticity of the rubber ring is good, the requirements for processing precision of the surfaces of a cylinder body and a cylinder cover are low, the medium resistance is strong, and the reliability of water as well as oil sealing can be ensured.
Description
Technical field
The utility model relates to a kind of diesel engine cylinder pad.
Background technique:
Existing diesel engine cylinder pad is the compound head gaskets of asbestos, adopts metal core board, is provided with asbestos slate on the upper and lower surface of metal core board, and it is metal guard ring bound edge that depressed structure is sealed in the firing chamber, and is provided with the steel wire ring in the metal guard ring; Oil sealing, seal water structure adopt the sealing tree lace that prints on asbestos slate.The problem of its existence is: 1, asbestos easily wear out as elastic material, not environmental protection, and thickness size can not be constant, and influence strengthens to engine performance.2, because this engine power is bigger, the water shutoff of asbestos material, oil sealing reliability are not high yet.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of reliability that improves motor envelope gas, water shutoff, oil sealing is provided, and satisfies the individual layer riveting type rubber ring structural metal head gasket of environmental requirement.
The utility model is achieved in that it has a pad, on pad, be provided with cylinder mouth, water oilhole, bolt hole and positioning hole, its special way is: described pad adopts the single-layer metal plate, the place is provided with metal ring at the cylinder mouth, rivet between described metal ring and the single-layer metal plate, be provided with annular corrugated muscle on the metal ring surface, the different formation thickness differences of described metal ring with the single-layer metal plate thickness, corresponding water oilhole place is welded with the endless metal skeleton on pad, is provided with rubber ring at the metal frame inner edge.
Utilize the working mechanism of the thickness difference replacement steel wire ring of cylinder mouth place and flat part sheet material; Oil sealing, water shutoff adopt rubber ring to replace the sealing tree lace that originally prints on asbestos slate.Spot-welded together by metal frame between rubber ring and the single-layer metal plate, technology is simple, saves cost.Cylinder oral area plane is pressed and is distributed well, owing to be to seal gas with all-metal material, can guarantee the constant of material thickness and this place's pressure values, can improve the reliability of envelope gas greatly; The rebound elasticity of rubber ring is good, and low to cylinder body, cylinder lid surface requirement on machining accuracy, the media-resistant ability is strong, can guarantee that oil sealing, water shutoff are reliable.
