Tilting pad thrust bearing

摘要

A tilting pad thrust bearing wherein each bearing pad in a circular array of pads is held in a retainer and is provided with a radially extending rib on the side opposite of the side that receives the thrust load. There are disks that have a planar surface on one side and a spherical surface on an axially opposite side. The respective ribs of the pads bear on the planar surfaces of the disks. The spherical surfaces of the disks bear on angulated wings of two adjacent leveling links in a circular array of links. The links have radial holes and are supported for pivoting on pins that extend radially from the retainer. The periphery of each pin makes tangential line contact with a hole. An extrapolation of the angulated wing surfaces extends through the line contact so there is no moment arm for frictional forces at the point contact on the wings to act through and free pivoting of the leveling links is not impaired.
