FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used in turbomachines, for instance, in turbocompressors, and also as repair set. Proposed thrust bearing has housing, bushing with bead freely fitted into housing space and fixed from rotation by section of bead in form of polyhedron and arranged in congruent cavity on end face of housing pointed to polyhedron. Longitudinal lubrication grooves are made in space of bushing whose spaces are connected through channels with outer surface of bearing housing. Bushing is made sectional, consisting of two parts, each provided with bead with fixing section in form of polyhedron. Both end faces of bearing housing are provided with cavities congruent to fixing sections of bead. Clearance is left between end faces of bushing arranged in space of bearing housing. ^ EFFECT: increased damping properties of bearing in axial and radial directions. ^ 4 cl, 2 dwg |
