Abstract
An oil-pressure-supplied bearing apparatus which is ideally suited for the support of rotating shafts receiving significantly heavy thrust loads such as the propulsion shaft of a vessel. A plurality of pressurized chambers receiving oil pressure and a plurality of pressurized clearances are formed facing each other on both sides of a plurality of floating discs fixed to the rotating shaft and between a pair of bearing housings supporting the rotating shaft. Oil delivered to the pressurized chambers is fed back to the oil tank via the pressurized clearances. When the pressurized clearance opposite the direction of the thrust load narrows, oil pressure in the pressurized chambers rises and resists the thrust load. Meanwhile, floating discs on the rotating shaft are lubricated by oil passing through those pressurized clearances. When the direction of the thrust load is reversed, the inverted thrust load is supported by the pressurized chamber and the pressurized clearance on the opposite side.
