Abstract
The invention relates to a method for producing components of a tilting-pad bearing (10; 10a), wherein: the tilting-pad bearing (10; 10a) has an outer ring (12; 12a) and multiple tilting pads (18; 18a) preferably arranged at regular angular intervals about a longitudinal axis (3; 46) of the outer ring (12; 12a); the tilting pads (18; 8a) are pivotably mounted with an outer surface (20; 20a) about a pitch line (26; 26a) on an inner surface (16; 16a) of the outer ring (12; 12a); and a blank (30; 30a) in the form a cylinder portion (14) having a constant wall thickness is used to produce the tilting pads (18) from a tilting pad ring (42) or to produce the outer ring (12a). The invention is characterised in that: a radial force (FR) acting in the direction of the longitudinal axis (3; 46) is applied to the cylinder portion (14) at multiple clamping points (33; 33a, 34; 34a, 35; 35a) in the region of its outer periphery (32; 32a), said radial forces (FR) elastically deforming the cylinder portion (14); an inner bore (38; 38a) having a round cross-section is subsequently produced on the inner surface (16; 16a) of the elastically deformed cylinder portion (14); and subsequently the radial…
