TURBINE COMPRESSOR WITH GAS MAGNETIC BEARINGS Russian patent published in 2015 - IPC F01D25/16 

FIELD: machine building.

SUBSTANCE: turbine compressor with gas magnetic bearings contains a rotor with compressor impeller. The compressor drive is turbine running on spent gases of internal-combustion engine, and cylindrical rotor is located on two support-thrust gas magnetic bearings. In each gas magnetic bearing the ring active electromagnet and two active radial electromagnets are installed to accept axial and radial forces respectively by interaction with the shaft, turbine impeller and ring insert of the compressor impeller out of the ferromagnetic material. In gas magnetic bearings the feeders are made to supply in axial and radial direction of the compressed air supplied from the discharge main line of the compressor.

EFFECT: invention ensures possibility of adjustment of the bearing carrying ability, increases efficiency of rotor oscillations dampening, and simplifies system of ail lubrication supply to bearings.
