Abstract
Abstract A sealed joint including a first member having a shaft affixed thereto, a second member having a bore receiving the shaft, an annular groove in the first member about the shaft and facing the second member, an annular seal in the groove, a sleeve within the bore and about the shaft and having a radially outwardly extending peripheral flange at the end thereof nearest the first member, the flange engaging the seal, and an axial adjusting device whereby the position of the sleeve within the bore may be axially adjusted to selectively set the pressure of the flange on the seal.
