THRUST BEARINGS, ROTATING MACHINERY HAVING THRUST BEARINGS, AND METHODS OF MAKING THRUST BEARINGS

摘要

A thrust bearing arrangement includes a top plate (102) extending about a rotation axis, a thrust plate (104) extending about the rotation axis and axially offset from the top foil plate, and a bump plate (106). The thrust plate (104) is orthogonal relative to the rotation axis. The bump foil plate (106) extends about the rotation axis, is axially offset from the thrust plate (104), and has an annular portion and two or more bump plate foil portions. The annular portion of the bump plate (106) is circumferentially interrupted by the bump plate foil portions of the bump plate (106). Rotating machines and methods of making thrust bearing arrangements for rotating machines are also described.
