Abstract
The utility model relates to a sealing element for an engine, in particular to a rubber sealing gasket. The rubber sealing gasket comprises a rubber body, and is characterized in that: an edge of a sealing surface of the rubber body is provided with a metal framework; the rubber body and the metal framework are combined into a whole through rubber vulcanization; the thickness of the sealing surface of the rubber body is greater than that of the metal framework; and mounting holes are uniformly distributed on the metal framework. By the rubber sealing gasket, the amount of compression of the rubber body can be accurately controlled, and the compression resilience is ensured to be in a safety range, so that the sealing reliability is improved; meanwhile, the mechanical property of the gasket is improved through the metal framework, and the convenience of installation is improved.
Description
Technical field
The utility model relates to engine sealing, relates in particular to a kind of rubber sheet gasketing.
Background technique
Oil, water-stop pad on the present motor; Especially such as the gasket seal than large part such as oil sump, cylinder head cover, sprocket wheel chamber; Be the gasket seal that adopts full rubber material mostly; Though it realizes that with the mode that employing is coated with sealer sealing compared many advantages, as solved that sealer gets into oil pocket or water cavity easily and be not easy defective such as cleaning when repairing, but had following shortcoming:
1. the sealing gasket of full rubber material because the compressibility of rubber is big, is difficult to accurately control pad compressed thickness when mounted, is prone to cause the bigger variation of dimensional chain, thereby is prone to influence the installation of related components; Because the compression resilience of rubber material is also big, be prone to when engine running, make related components to produce vibrating noise in addition;
2. the sealing gasket of full rubber material, because the rubber material is very soft, whole pad all can have great distortion when on motor, installing, the fitting operation difficulty; Also need on relevant flanged surface, process the groove class formation for this reason pad is embedded wherein, so that the location when guaranteeing to install, this has just increased manufacturing procedure, has improved the whole cost of motor;
3. the sealing gasket of full rubber material; Because rubber exists inevitably aging; The degree that also can aggravate to wear out under the temperature when engine running and the influence of vibration; Make pad attenuation and lose good rebound elasticity under the effect that receives the fixing bolt axial force, thereby cause that bolt is lax, sealing force descends, cause seal failure.
The model utility content
The utility model is directed against full rubber material inconvenient installation, causes dimensional chain variation and easy ageing to cause deficiencies such as seal failure easily, and a kind of novel rubber sheet gasketing is provided.This pad can effectively overcome the above-mentioned defective of existing technology.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of rubber sheet gasketing, comprise rubber body, and its characteristics are that the sealing surface edge of said rubber body is provided with metal frame.
The beneficial effect of the utility model is: owing to be provided with metal frame at the sealing surface edge of rubber body, can accurately control the decrement of rubber body, guarantee compression rebound in safety range, thereby improved sealing reliability; Utilize metal frame to improve the mechanical property of pad simultaneously, thereby improved the installation convenience.
On the basis of technique scheme, the utility model can also be done following improvement:
Further, said rubber body and metal frame are combined as a whole through the vulcanization of rubber.
Adopt the beneficial effect of above-mentioned further scheme to be, this combination has utilized the sulfuration solidifying characteristics of rubber itself, makes rubber body combine firmly with metal frame, and technology is simple.
Further, the sealing surface thickness of said rubber body is greater than said metal frame thickness.
Adopt the beneficial effect of above-mentioned further scheme to be, guarantee to utilize its sealing surface rubber elasticity, and can not influence sealability because of metal frame.
Further, be evenly equipped with mounting hole on the said metal frame.
The beneficial effect that adopts above-mentioned further scheme is to be convenient to install, and also can make said rubber sheet gasketing not scurry the position through construction bolt and locating column simultaneously.
Further, said rubber body is fluorine rubber, nitrile rubber, silicone rubber, ACM or ethylene-acrylate rubber.
Further, said metal frame is aluminium, aluminum alloy or lightweight steel plate.
Adopt the above further beneficial effect of scheme to be, can bear pressure size and usage requirement, adopt different rubber materials or metal frame material according to Sealing.
