Rotor for a fluid-dynamic system of bearings has hydrodynamic radial/axial bearing structures on selected surfaces to take the shape of recesses and/or bumps

摘要

A rotor (1) and radial bearing structures (2,3) are produced in common in an operating cycle, e.g. by sintering, injection molding or extrusion molding. The rotor includes a shaft. The radial bearing structures are arranged on the shaft's peripheral surface. An independent claim is also included for a method for producing a rotor.
