Abstract

A tilting pad radial bearing for a single-shaft turbomachine is provided having a support ring, tilting pad, and tilting pad support with an aligning device rigidly fixed to the inner face of the support ring and which has a convex sliding surface facing inwards and concave sliding surface facing outwards, the concave sliding surface rigidly fixed to the outer lying rear face of the tilting pad. The sliding surfaces lay one above the other, and each surface is a circular arc in each sliding surface longitudinal section. The aligning device keeps the axial position of the tilting pad adjustable relative to the support ring such that an angle of attack of the sliding surface of the tilting pad is adjustable relative to the axis of the tilting pad radial bearing dependent on the axial position of the concave sliding surface relative to the axial position of the convex sliding surface.
