Description

Sealing gasket structure at front end of crankshaft pulley

Technical Field

The utility model relates to a technical field of internal-combustion engine, more specifically say, the utility model relates to a seal gasket structure of crankshaft pulley front end.

Background

As shown in fig. 1, since the pulley 3 and the timing sprocket 6 are metal surfaces and the metal surfaces are pressed by the pressing force of the bolt member 1, they do not have sealability. The engine oil in the chain case flows into a circumferential gap between a crankshaft pulley piece 3 at a position B and a crankshaft end 4 of a crankshaft 7 from a joint surface at the position A, and finally flows out from a joint position D of a bolt 1 and a gasket 2 and a joint position C of the gasket piece 2 and the crankshaft pulley piece 3 to pollute the front end of the crankshaft pulley, dust can be adhered for a long time, and poor appearance feeling is caused.

SUMMERY OF THE UTILITY MODEL

For solving the above-mentioned technical problem that exists among the prior art, the utility model aims to provide a seal gasket structure at crankshaft pulley front end.

The utility model discloses a seal gasket structure at crankshaft pulley front end, including annular rubber structure, annular interior metal framework and annular outer metal framework, annular rubber structure, annular interior metal framework and annular outer metal framework set up with one heart, and annular rubber structure's height is greater than metal framework and annular outer metal framework's height in the annular, metal framework and annular outer metal framework's height equals in the annular, be provided with the inner groovy on annular rubber structure's the medial surface, be provided with outer recess on annular rubber structure's the lateral surface, metal framework inlays in the annular on the inner groovy, the outer metal framework of annular inlays on the outer recess.

And the annular inner metal framework and the annular rubber structure form a vulcanization fixing structure.

And the annular outer metal framework and the annular rubber structure form a vulcanization fixing structure.

Compared with the prior art, the utility model discloses a seal gasket structure at crankshaft pulley front end has following beneficial effect:

the utility model discloses a seal gasket structure of crankshaft pulley front end possesses sealing capacity, can guarantee that the packing force of bolt is effectual to be acted on the working face, can guarantee again sealedly, solves the machine oil seepage problem.

Detailed Description

The sealing gasket structure at the front end of the crank pulley of the present invention will be further described below with reference to specific embodiments to help those skilled in the art understand the technical solution of the present invention more completely, accurately and deeply.

Example 1

As shown in fig. 2, the sealing gasket structure at the front end of the crank pulley of the present embodiment includes an annular rubber structure 10, an annular inner metal framework 20 and an annular outer metal framework 30, where the annular rubber structure 10, the annular inner metal framework 20 and the annular outer metal framework 30 are concentrically disposed, the height of the annular rubber structure 10 is greater than the heights of the annular inner metal framework 20 and the annular outer metal framework 30, and the heights of the annular inner metal framework 20 and the annular outer metal framework 30 are equal. An inner groove 11 is formed in the inner side face of the annular rubber structure 10, an outer groove 12 is formed in the outer side face of the annular rubber structure 10, the annular inner metal framework 20 is embedded in the inner groove 11 and forms a vulcanization fixing structure with the annular rubber structure 10, and the annular outer metal framework 30 is embedded in the outer groove 12 and forms a vulcanization fixing structure with the annular rubber structure 10.

The sealing gasket structure at the front end of the crankshaft pulley is characterized in that an inner framework and an outer framework are fixed together by rubber to integrally form a composite gasket structure, a metal framework has bearing capacity, bolt pretightening force is guaranteed, and meanwhile the sealing of the end face is completed by the rubber. The sealing gasket structure at the front end of the crankshaft pulley of the embodiment perfectly solves the problem of engine oil leakage at the front end of the crankshaft pulley.

For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
