Elastomeric seal anti-extrusion wedge backup ring and flange |
摘要 |
A seal assembly for a shaft has a flange fixed to a work piece having a bore hole therein. The flange encircles the shaft and includes a triangular shaped projecting member having first and second surfaces extending from the flange into the bore hole. An angle is formed between the first and second surface. The first surface of the projecting member is in contact with an inner surface of the bore hole or the outer surface of the shaft. An o-ring encircles the shaft and a backup ring is positioned within a space between the shaft, the flange and the o-ring or between the bore hole, the flange and the o-ring. Subject to axial forces, the backup ring undergoes a wedging action between the shaft and the triangular shaped projecting member or between the bore hole and the triangular member to seal where the shaft penetrates the work piece.
