A SHAFT SEAL

摘要

The present invention relates to a shaft seal (1) comprising a sealing element (14) mounted co-axially to a rotary sealing ring (10) to form a primary seal between opposed faces thereof to substantially prevent fluid flow across the primary seal. The sealing ring (10) is mounted about the shaft (2) on an inner sleeve (11). The inner sleeve is fixed to the shaft to be axially and rotationally fast. The sealing ring (10) is connected to the inner sleeve (11) by half-moon shaped locking members (12) extending through the inner sleeve (11) outwardly into the sealing ring (10). The locking members (12) lock the sealing ring (10) rotationally and axially fast on the inner sleeve (11).
