ABSTRACT:
A tilting pad thrust bearing in which the sector-shaped pads are supported on individual disks. A runner runs on top of the pads. The disks have a spherical element projecting from their bottoms. The elements make tangential contact with a stationary support ring and the pads and disks tilt about an axis on which the point of tangency lies. The tilt axis of each pad is located at 70% to 80% of the length of an arc extending from the leading edge to the trailing edge of the pad midway between the radially outermost and innermost edge of the pad.
