AN EMERGENCY WARNING SIGNALLING METHOD WHEN INCREASING FRICTION IN THE BEARINGS OF A SHIP'S SHAFT
The method of emergency-warning signalling, when there is an increase in friction in the bearings of a ship's shafting, which has an electrogalvanic circuit closed at the hull, is distinguished in that with the purpose of determining oil leakage in a timely manner from the bearing below the permissible limit, the change of electrical resistance of the oil film in the electrogalvanic circuit of the propeller-hull pair is used as the signal indicating an increase of friction.
