A STUDY OF A STERN TUBE SEALING DEVICE FOR LARGE, HIGH SPEED SHIPS

As the lignumvitae bearings that have been customarily used for stern tube bearings have proved to be incapable of keeping pace with the increase of size and cruising speed of ships on account of their low wear resistance, they have been mostly replaced by white metal bearings. With white metal as the stern tube bearing, however, troubles in the associated sealing device occurred frequently. Though such troubles were solved one by one, new unexpected troubles may occur with the power and speed becoming greater. Tests carried out on a 1180 mm diameter stern tube sealing device with respect to temperature of the seal sliding part when operating at various high speeds and light drafts, friction loss at the seal rings, and oil leakage due to vibrations of the shaft liner have led to successful development of a stern tube sealing device of oil lubrication type to serve for high-speed and light-draft ships. The important improvements were in the number and arrangement of seal rings.
