Plain bearing for turbomachine rotor and turbomachine with plain bearing

摘要

A plain bearing for a turbomachine rotor is proposed. The plain bearing has a bearing body for mounting the turbomachine rotor and has a solid lubricant powder for lubricating a bearing contact area between the bearing body and the turbomachine rotor. The bearing body is produced from an acid-gas-resistant, solid-solution-strengthened powder of a nickel-based material or from a martensitic, austenitic or ferritic-austenitic non-rusting powder of a steel material, and the solid lubricant powder is produced from an acid-gas-resistant material. The bearing body has a hardness of at most 40 Rockwell hardness HRC.
