Abstract
A tilting pad thrust bearing arrangement (,), comprises a circular array of pads (,, . . . ) having tilt pivots (,, . . . ) and supported spaced from a carrier surface (,) by supporting springs (,) in the form of a stack of at least two annular, axially deflectable spring members (,). Each spring member (,and,) is spaced from an adjacent surface, the carrier surface (,) and spring member (,) respectively, by an array of deflection pivots (,, . . . ) disposed one pivot each between the tilt pivots of adjacent pads and acting as a fulcrum for spring deflection. The spring deflection pivots are in line axially so that upon axial loading of the bearing pads the spring (,) closest to the pads deflects at a first rate to contact the next spring (,) and the spring combination deflects at a second rate, at least until it contacts the carrier surface (,). Any number of springs may be stacked to give appropriate overall progressive deflection characterising.
