ROTARY MACHINE OPERATING METHOD Russian patent published in 2016 - IPC F01D3/04 

FIELD: machine building.

SUBSTANCE: invention relates to an operating method for a rotary machine with bearing (39) where rotor (14) is installed, which in certain moment of operation is exposed to thrust force effect, which affects, mainly, only in axial direction and is perceived and withdrawn by first thrust bearing (43) of bearing (39) through a lubricant, herewith bearing (39) contains second thrust bearing (45). To damp or even prevent axial oscillations of rotor (4) it is proposed that in case of thrust force appearing at the same time second thrust bearing (45) at least periodically creates a force acting on first thrust bearing (43) in the direction of thrust.

EFFECT: proposed is a rotary machine operating method.
