DICHTUNGSANORDNUNG

A resilient shaft sealing lip is biassed to bear against a shaft when the shaft is at rest to prevent egress of lubricating liquid past the sealing lip, but upon rotation of the shaft at its rated speed the lip lifts so that sealing friction forces are limited to those generated by liquid friction and a return conveyor mechanism provided in combination with the lip, is effective upon shaft rotation to return escaping liquid and thereby take the place of a tight sealing lip for this purpose. The arrangement thereby provides reduced wear, reduced heat generation and reliable prevention of leakage with long service life consistent with economical and modular construction.
