ABSTRACT:
An oil lubricated, double tilting, three pad journal bearing includes three pads asymmetrically located with respect to each other and with respect to the horizontal and vertical centerline of a horizontally disposed steam turbine shaft. Each pad has associated therewith an oil feed dam. Apparatus for lubricating supplies oil to a channel, formed by the feed dam and its corresponding pad, and the rotating shaft draws the oil from the reservoir as a film into the interstice defined by the shaft surface and the pad face.
