GREASE LEAKAGE PROTECTION STRUCTURE FOR RUDDER STOCK IN VESSEL

摘要

PURPOSE: A grease leakage preventing structure for a rudder stock of a ship is provided to prevent grease from discharging to seawater through a rudder stock by overlapping a first sealing unit and a second sealing unit, thereby preventing seawater pollution beforehand. CONSTITUTION: A grease leakage preventing structure for a rudder stock of a ship comprises a bearing, a first sealing unit(20), and a second sealing unit(30). The bearing is installed to rotatably support a rudder stock(10) on the top of a rudder trunk(12). The first sealing unit prevents the leakage of grease coated on the bearing. The secondary sealing unit is installed on the exterior of the rudder stock to collect the grease leaked from the first sealing unit.
