Abstract
A sealing gasket for an oil pan is provided with an annular portal type opening. The sealing gasket comprises a bolt mounting hole formed along the gasket annularly and is characterized in that a rigid bushing is arranged in the mounting hole, and the height thereof is less than the thickness of the gasket. The bushing is made of metal materials. Two sealing ribs are arranged on the front surface and the reverse surface of the sealing gasket. A positioning boss is arranged on the reverse surface of the sealing gasket. The rubber sealing gasket is combined in a vulcanizing manner through adding the metal bushing; and the thickness of the bushing fully considers the compression amount of the rubber gasket, so that the rubber gasket is kept within the proper compression scope and can not bear larger compressing force. The seal of the oil pan of a portal-type engine is also fully considered; in order to ensure the assembly of the gasket, the positioning boss is arranged on the sealing gasket, thereby ensuring the accurate positioning of the gasket. A groove is formed in the middle of the rubber gasket to form a sealing rib, thereby ensuring both the tight joint of the gasket and the oil pan and the sealing performance.
Description
Technical field
The utility model relates to a kind of pad, relates in particular to a kind of bottom-end gasket sheet reliable, that can reduce the engine oil leakage risk that seals
Background technique
Gasket seal occupies very consequence in modern industry, phenomenon such as the seal failure meeting causes oozes, emit, drip, leakage has a strong impact on the performance of part.If seal badly, even can cause the inefficacy of part even cause serious accident.The major function of oil sump is to store machine oil and machine oil is provided for lubrication system, constitutes crankcase with framework.How sealing also is the important topic of present automobile industry to oil sump.At present, adopt the mode of gluing mostly.There are many hidden danger of quality in this sealing technique, and it is very high to the quality requirement of sealing surfaces, sealing surfaces is as there being cut slightly, just might cause motor generation oil impregnate phenomenon, in addition because some factories adopt the assembly technology of artificial gluing, if gluing is inhomogeneous, these glue-lines are when being squeezed, be easy to cause the obstruction of bolt hole or framework spill port, when motor can not get oil return timely, even can cause the risk that crank shaft oil seal is rushed out.On the other hand, when motor was reprocessed or changed oil sump, the sealer on framework or the oil sump must be removed again, and removing work is wasted time and energy, and befouling environment.In order to improve the sealing condition of existing oil sump, some producers have adopted the mode of rubber sheet gasket sealing, but because the ability that rubber material meets with stresses is relatively poor, in use for some time, be under pressure and the acting in conjunction of temperature, gasket seal is easily aging or lax, on the other hand because rubber material resistance to pressure and compression rebound are limited in one's ability, when being subjected to too the compressing of connecting bolt, pad has lost the ability of original resiliently deformable, causes the sealability variation of pad or loses sealability.
Summary of the invention
The purpose of this utility model is to provide a kind of bottom-end gasket sheet, and solution pad amount of deformation is too big, sealing is unreal, the technical problem that the life-span is short.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of bottom-end gasket sheet, ring-type with gantry mouth, comprise the one group of bolt mounting holes that is provided with along gasket ring, it is characterized in that: in the described mounting hole rigid liner is set, described lining height is less than spacer thickness.Described lining is a metallic material.
For enhanced leaktightness, the tow sides of described gasket seal all are provided with two sealed muscles.
In order to prevent that pad from sliding, the reverse side of described gasket seal is provided with one group of positioning boss.
The utility model is considered some defectives in the existing product fully, on the basis of existing pad, pass through to increase metal lining, and combine with rubber sheet gasket by vulcanization, the thickness of lining has taken into full account the decrement of rubber sheet gasket, make it remain on appropriate compression zone, be unlikely to bear excessive compressive force.Also taken into full account the sealing of the oil sump of planer-type motor,, on gasket seal, be provided with one group of positioning boss, guaranteed the accuracy of pad location in order to guarantee the assembling of pad.Be provided with groove again in the middle of the rubber sheet gasket and form sealed muscle, guaranteed and the fitting tightly of pad and oil sump, guaranteed sealability.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.

Embodiment
Shown in Fig. 1,2,3,4,5,6, a kind of bottom-end gasket sheet 1 has the ring-type of gantry mouth 6, comprises the one group of bolt mounting holes 2 that is provided with along pad 1 ring.In the described mounting hole 2 rigid liner 3 is set, described lining height is less than spacer thickness.Lining is metallic material or other rigid material.This lining combines with rubber sheet gasket by vulcanization.The thickness of lining has taken into full account the decrement of rubber sheet gasket, makes it remain on appropriate compression zone, is unlikely to bear excessive compressive force.
For enhanced leaktightness, the tow sides of described gasket seal 1 all are provided with two sealed muscles 5.For the sealing of pad provides good assurance.At Long Menkou, in order to guarantee the reliable sealing here, the pad Cross section Design at gantry mouth 6 places is become concaveconvex structure, the groove 4 of gantry mouth 6 matches with the projection of oil sump, and the sealed muscle on groove 4 both sides has been guaranteed the sealing reliability at this place.
In order to prevent that pad from sliding and assembling and positioning, the reverse side of described gasket seal 1 is provided with one group of positioning boss 7.Described boss is 4, is arranged on the four edges of pad.
Claims (5)
