Abstract

The rotor is constructed as a hollow cylinder of boron, partic. for use as a high speed centrifuge drum produced by depositing a boron film on a substrate in the shape of the rotor of e.g. tungsten. The tungsten substrate is subsequently removed and the boron rotor is left hollow unless the substrate is coated on both sides in which case it remains inside. The rotor is axially and radially supported in a lower cup needle bearing (12) and is concentrically guided in an upper magnetic bearing (13). Drive is applied by a gas jet (18) towards a turbine wheel (19) mounted coaxially on the upper end of the rotor.
