ABSTRACT:
An arrangement of a shaft with a slip-ring seal mounted thereon is disclosed. The slip-ring seal (3) comprises a pair of cooperating slip rings (4,5), the sealing faces of which define a sealing gap (6) between them. One of the slip rings is mounted on the shaft (2) with torque transmission from a drive element (9) mounted on the shaft, whilst the other slip ring is provided for fixed mounting on a stationary component. The arrangement is characterised in that the drive element (9) comprises a tubular drive housing (11), extending over the external circumference of the slip ring (4) with a radial gap (12) and a passage (13) for introduction of a flow medium is provided, opening out at one end in a chamber (A), defined by the drive housing (11), which drains out through the radial gap (12), whereby the radial gap forms a flow path for the flow medium which terminates at or near the sealing gap (6).
