  • Fluid equalized tilting pad thrust bearings
    Patent number: 4544285
    Abstract: A thrust bearing for a main propulsion shafting system on a ship having ting pads and fluid equalizing pistons. Hydraulic oil fills a recess on the face of each pad to provide additional lubrication and hydrostatic pressure to allow the bearing to handle added load capacity. The system for supplying oil to the recess may either be separate from the piston equalizing hydraulic system or part of a combined system. In the combined system, stationary control pads sense the oil thickness and control the oil flow.
