Abstract
The utility model discloses a rubber seal ring embedded with dual spring steel pieces. An internally arranged spring steel piece is embedded in a rubber ring outer ring body and an externally arranged spring steel piece is embedded outside a rubber ring inner ring body. Two monomers of the internally arranged and externally arranged spring steel pieces are both L-shaped, and the internally arranged and externally arranged spring steel pieces form a door-shaped arrangement structure staggered up and down in the rubber seal ring. The two monomer L-shaped steel pieces are embedded in the inner and outer rings of the rubber seal ring, thus improving the strength and the sealing property of the seal ring. The seal ring is assembled on a rocker chamber shell, a track support penetrates through an inner hole of the seal ring, the seal effect is enhanced by the elastic forces of the two steel pieces, and the elastic force of the L-shaped steel pieces can also ensure that the seal ring can be firmly assembled onto the rocker chamber shell without the striping due to reasons such as vibration. The seal ring is simple in structure and is suitable for the temperature ranging from 40 DEG C below zero to 230 DEG C; the seal ring is corrosion-resistant; the compression amount of the seal ring accords with the characteristics of the rubber and spring steel piece materials; and the rubber seal ring with the dual spring steel pieces can resist stronger pressure with the remaining of the sealing capacity.
Description
Technical field
The utility model belongs to engine component, is specifically related to the rubber seal between a kind of rocker arm bonnet and rail support.
Background technique
Rocker arm bonnet and rail are the strength members of motor, and rail coupling is between Injection Pump and oil sprayer, and the inner hyperbaric chamber that forms, improve jet pressure in-orbit.Have the characteristics that oil gas (mixture) pressure is large, temperature is higher in rocker arm chamber cover, so must adopt seal with elastometic washer between rocker arm bonnet and motor rail support.But the area between rocker arm bonnet and rail support mounting hole position is narrow, adopts the General Purpose Rubber cushion rubber to be easy to cause the sealed ring deformation leakage of oil.And the cushion rubber position is in the cylinder top, is subjected to scorching of outlet pipe, and Tail Pipe Temperature is generally all more than 130 ℃, and cushion rubber one side is immersed among machine oil simultaneously, and opposite side is exposed in the thermal environment air, so the O-ring seal failure rate is higher.
Of the present utility modelly accordingly proposed a kind of new seal with elastometic washer structure, the not tight and easy problem of aging of seal with elastometic washer is resolved.
Summary of the invention
The purpose of this utility model is, proposes a kind of seal ring of all inlaying spring steel plate inside and outside rubber, when guaranteeing close sealing, also avoided because of problems such as seal ring that engine vibration causes come off.
Below in conjunction with accompanying drawing, know-why of the present utility model and structure are described.
Stud with the rubber seal of dual spring steel disc, comprise spring steel plate and rubber ring, stud with built-in spring steel plate in the body of rubber ring outer ring, at this external external spring steel disc that studs with of rubber ring inner ring.Two monomers of built-in spring steel plate and external spring steel disc are L shaped, and built-in and external spring steel disc forms the door shape layout of dislocation up and down in rubber seal.
Its principle is that two L shaped steel discs of monomer are embedded in the inner ring outer ring of rubber seal, improve thus intensity and the sealing of its seal ring.Seal ring is assemblied on rocker arm chamber cover, track support passes from ring inner hole, elastic force by two steel discs in seal ring carrys out the enhanced leaktightness effect, and the elastic force by L shaped steel disc can guarantee that also seal ring firmly is assembled on rocker arm chamber cover simultaneously, and can not come off because of reasons such as vibrations.
The beneficial effect of characteristics of the present utility model and generation is, all inlay spring steel plate inside and outside rubber seal, can effectively guarantee the sealing of seal ring, also avoid coming off or the rocker arm chamber cover inner high voltage causes poorly sealed problem because of seal ring that engine vibration causes.The cushion rubber inside and outside wall is because forming sealing strip with the workpiece close contact simultaneously.The seal ring decrement meets the material behavior of rubber, spring steel plate, can tolerate than strong pressure and keep its sealability.
Description of drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram.
Fig. 2 is the utility model L-type steel disc structural representation.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is further described.
Stud with the rubber seal of dual spring steel disc, comprise spring steel plate and rubber ring, it is characterized in that studding with built-in spring steel plate 2 in rubber ring 1 outer ring body, at this external external spring steel disc 3 that studs with of rubber ring inner ring.Two monomers of built-in spring steel plate and external spring steel disc are L shaped, and built-in and external spring steel disc forms the door shape layout (as Fig. 1) of dislocation up and down in rubber seal.
The total height h4 of rubber ring is 7.5mm, and the height h2 of built-in spring steel plate is 6mm, and wide h1 is 0.75 mm; The height h3 of external spring steel disc is 4mm, and width is also 0.75 mm(such as Fig. 2).
Rubber ring is assemblied in the rail bracket holes that covers the engine rocker chamber, and track support passes from the rubber ring endoporus, by the cushion rubber inside and outside wall, because of the while, with the workpiece close contact, forms sealing strip.When seal ring is subject to the extruding force of track support, the spring steel plate in seal ring will produce opposite spring force, guarantee that thus seal ring has good sealability.Spring steel plate is shaped as L-type, and relatively straight shape steel plate can produce better elastic force, makes sealing effect better.
Sealing circle Applicable temperature-40 ℃～+ 230 ℃, corrosion-resistant, the seal ring decrement meets the material behavior of rubber, spring steel plate, can tolerate than strong pressure and keep its sealability.
Claims (2)
1. stud with the rubber seal of dual spring steel disc, comprise spring steel plate and rubber ring, it is characterized in that studding with built-in spring steel plate (2) in the body of rubber ring (1) outer ring, at this external external spring steel disc (3) that studs with of rubber ring inner ring, built-in spring steel plate (2) and (3) two monomers of external spring steel disc are L shaped, and built-in and external spring steel disc forms the door shape layout of dislocation up and down in rubber seal.
2. according to the rubber seal that studs with the dual spring steel disc claimed in claim 1, the total height that it is characterized in that described rubber ring (1) is 7.5mm, and the height of described built-in spring steel plate (2) is 6mm, wide 0.75 mm; The height of described external spring steel disc (3) is 4mm, wide 0.75 mm.
