TILTING PAD RADIAL BEARING WITH AN ALIGNING DEVICE FOR A SINGLE-SHAFT TURBOMACHINE

摘要

A tilting pad radial bearing for a single-shaft turbomachine has a support ring (2), a tilting pad (4), and a tilting pad support (3) with an aligning device (8) which is rigidly fixed to the inner face of the support ring (2) and which has a convex sliding surface (18) that faces inwards and a concave sliding surface (19) that faces outwards, said concave sliding surface being rigidly fixed to the outer lying rear face (6) of the tilting pad (4). The sliding surfaces (18, 19) lie one above the other, and each surface is a circular arc in each sliding surface longitudinal section. The aligning device (8) is designed to keep the axial position of the tilting pad (4) adjustable relative to the support ring (2) such that an angle of attack of the sliding surface (5) of the tilting pad (4) can be adjusted relative to the axis of the tilting pad radial bearing (1) dependent on the axial position of the concave sliding surface (19) relative to the axial position of the convex sliding surface (18).
