Abstract

To avoid completely dry mating faces and hence rapid wear and failure of a rotating shaft seal, one component is vibrated to allow controlled leakage of fluid contained under pressure. Vibration is produced electrically, mechanically, or hydraulically. The rotating shaft (1) has fixed to it a collar (5), by which an axial load may be applied via a spring (8) to a sleeve (7) which forms one of the seal components. The main sealing faces (14, 15) are formed between the sleeve and non-rotating ring (13) sealed (16) to the supporting body (2). A vibrator (17) transmits vibrations via a lever (18) to the ring, causing intermittent contact between the main sealing faces and thus a regulated amount of lubrication and leakage.
