Abstract
The utility model relates to a sealing component used for automobiles and the crankshafts of motorcycle engines, which is a frame type rubber oil seal. The utility model is characterized in that the section of an annular metallic frame 2 is side T-shaped, the surface of the upper and the bottom sealing lips is attached with a polytetrafluoroethylene protective layer 4. Owing to all the technical characteristics, the utility model has a strong anti-deformation ability and has the advantages of high-temperature resistant, abrasion resistant, good corrosion resistant, etc., and therefore, the service life is long.
Description
The utility model relates to the Sealing of power plant, particularly a kind of sealing gasket that is used for automobile, motorcycle engine crankshaft.
The sealing gasket that is used for automobile, motorcycle engine in the prior art exists non-refractory, the defective of rub resistance and corrosion not, often influences the proper functioning of motor, thereby needs often to change.In addition,, make difficulty of processing big on the one hand, make the sealing gasket easy deformation on the other hand because the skeletal structure of sealing gasket is unreasonable.
The purpose of this utility model is to provide the rubber oil seal with reinforce of a kind of not only high temperature resistant but also rub resistance and corrosion.
Above-mentioned purpose of the present utility model is to realize by such structure; be that it is the oil resistant rubber circle body that includes the annular metal skeleton; be with spiral elastic ring in the groove of its upper and lower sealing lip periphery; the cross section that it is characterized in that described annular metal skeleton is a side T shape, and the surface attachment of upper and lower sealing lip has a teflon protective layer.
Said structure of the present utility model is further specified by accompanying drawing.
Accompanying drawing is a generalized section of the present utility model.
Referring to accompanying drawing, it is the annular metal skeleton of side T shape that a cross section is arranged in oil resistant rubber circle body 1, cover spiral elastic ring 3 in the groove of the upper and lower sealing lip periphery in the oil resistant rubber circle body, and the surface attachment of upper and lower sealing lip has a teflon protective layer 4.Described annular metal skeleton is combined by two ring-type stamping part, and a stamping part cross section is inverted U-shaped, and horizontal flange is arranged, and another stamping part cross section is L shaped, and its compound section, two stamping part combination back is a side T shape.This knockdown metal frame can reduce processing cost, reduces materials consumption.Described teflon protective layer 4 is to adopt the mold membrane textural association to constitute to the sealing lip surface.
The utility model has been owing to adopted described skeleton structure, thereby has strong mechanical strength and non-deformability; To have a coefficient of friction little owing to adhered to the polytetrafluoroethylene (PTFE) protective layer at the sealing lip actinal surface; when rotating, crankshaft high-speed heats up at the end; the advantage such as wearability, corrosion resistance and good had both prolonged service life of sealing gasket, had guaranteed again the normal operation of power part.
Claims (2)
1, a kind of rubber oil seal with reinforce; for including the oil resistant rubber body of annular metal skeleton; be with spiral elastic ring (3) in the groove of its upper and lower sealing lip periphery; it is characterized in that: the cross section of described annular metal skeleton (2) is a side T shape, the surface attachment teflon protective layer (4) of upper and lower sealing lip.
2, rubber oil seal with reinforce according to claim 1, it is characterized in that: the cross section is that the annular metal skeleton (2) of side T shape is combined by two ring-type stamping part, wherein one for the cross section is inverted U-shaped, and the ring bodies of horizontal flange is arranged, and another is down L shaped ring bodies for the cross section.
