Abstract

For the sealing of an oil-lubricated bearing (2, 3) of a drive shaft (1), a leakage space (20) and an adjoining oil chamber (30) are arranged between a slide ring seal (11, 12) and the bearing. The oil chamber is bounded by two outer lip seals (25, 27) and contains a further, normally unloaded inner lip seal (26). If a water pressure, which is higher than the normally low oil pressure in the oil chamber (30), should build up in the leakage space (20) and a collecting chamber (41) connected therewith, the oil pressure in the forward oil chamber compartment (30b) is increased to about half that of the water pressure. The changing of the pressures in the oil chamber compartments (30a and 30b) activates the inner lip seal (26), which, however, is subjected to only half the pressure difference between the ambient water pressure and the low oil pressure in the bearing. <IMAGE>
