ABSTRACT:
A seal for a rotating shaft is disclosed which seals the shaft as it passes through a stationary partition wall. The seal has a segmented graphite sealing ring extending around the shaft located in an annular recess of a casing attached to the partition wall. A retaining ring having axial projections extending into radial grooves defined by the sealing ring is attached to the casing and a retaining washer extends circumferentially between the graphite segments and the retaining ring to prevent any relative axial movement between the elements. Relative rotation and axial movement between the retaining ring and the casing is prevented by stop pegs and a stop ring.
