Abstract
PURPOSE: To prevent the stray current corrosion of the sleeve perfectly by a method wherein carbon brushes are approached to the sleeve of the propeller shaft to be contacted therewith at two places thereof and the connecting wires thereof is fixed to a packing gland of the stern tube.
CONSTITUTION: The carbon brushes 4, 5 are respectively contacted with two contact points (a), (b) of the sleeve 2 not splashed with sea water and the connecting wires 6 thereof is fixed to the packing gland of the stern tube. An electroconductive luburicating agent is coated to the fixing points of the connecting wires 6 and the contact surfaces of the brushes 4, 5 and a finishing accuracy of slide surfaces of the carbon brushes 4, 5 is a smooth surface of a top finish and the spray type electroconductive lubricating agent is periodically sparyed to the slide surfaces to prevent the electrical bad contact. Thereby, stray current discharged toward the stern tube from the sleeve 2 of the propella shaft 1 is taken out by the carbon brushes 4, 5 whose contact has been ensured and passed to the packing gland of the stern tube by the cable 6 to eliminate the discharge phenomenon of the stray current.
