<p><PICT:1096421/C6-C7/1> To prevent corrosion in the rear seal on a ship's propeller shaft 30, a babbit metal bearing 88 is insulated from its supporting ring 84 by a member 86, and the ring 84 is electrically connected to the hull by e.g. straps 118. Seals 68, 70, 72, 74 prevent the escape of oil, which is fed by gravity to chambers 108, 110, and the ingress of sea water which is allowed into the chamber 114 through openings 58, 60.</p> |
