Abstract
A seal assembly for a shaft supporting a rotary element comprises a sealing ring having an inner radial surface in contact with a seal surface of the shaft. The sealing ring comprising a disc shaped integral radial lip normal to the inner radial surface. A disc shaped seal shield is assembled in sealing contact with a first surface of the integral disc shaped radial lip and also in sealing contact with a first radial surface of an annular seal groove. An energizer positioned in the annular seal groove is in contact with the bottom surface of the groove and a second radial surface of the groove. The energizer exerts a radial force on the outer radial surface of the sealing ring and a lateral force on the integral radial lip of the sealing ring.
