TILTING-SEGMENT RADIAL BEARING FOR A SINGLE-SHAFT TURBOMACHINE

摘要

The invention relates to a tilting-segment radial bearing for a single-shaft turbomachine, comprising a support ring (3), a tilting-segment mounting (4) and a tilting segment (5), which in the installed state of the tilting-segment radial bearing (1) is supported on the support ring (3) such as to be seated on top and be radially displaceable by the tilting-segment mounting (4), said mounting comprising a preload device (20), by means of which the tilting segment (5) is preloaded in the direction toward the shaft of the single-shaft turbomachine when the operating rotational speed of the single-shaft turbomachine is above a predetermined tilting-segment preload rotational speed, such that the tilting segment (5) can be radially moved without preload when the operating rotational speed of the single-shaft turbomachine is below the tilting-segment preload rotational speed.
