Abstract

The shaft seal has an annular collar fixed to the shaft. A nonrotatable sleeve encompasses the shaft and is biased axially towards the collar. A free-floating carbon seal is interposed between them. A contact ring is loosely positioned within a recess formed within the rotating collar and has a sealing surface adapted to ride face-to-face sealing contact against the carbon ring. The contact ring is resiliently supported within the recess providing the assembly with sufficient flexibility to allow for shaft run-out without disturbing the integrity of the face-to-face sealing contact. Cooling fluid is passed over the contact ring and the sealing ring to prevent excessive heating.
