Abstract

PURPOSE:To safely operate the rotor in the rotary machine with low vibration value by providing a static pressure rotor floating unit at a bearing unit for supporting the rotor and floating the rotor at the speeds of the range in the vicinity of its critical speed, thereby preventing the resonance of the rotary machine. CONSTITUTION:A sliding bearing 2 for supporting the rotor 1 accommodates a high pressure oil supply hole for hydrostatically floating the rotor, which hole is connected to an oil supply tube 3. High pressure oil is supplied by an oil pump 5 which operates or stops upon reception of the revolution of the rotor as an electric signal 4. A check valve 12 is provided to prevent backflow of the oil, and wasted oil is recovered through a waste oil tube 6 to an oil tank 7. Since the static pressure rotor floating unit can be accordingly operated at the speed of the range in the vicinity of critical speed to thereby increase the thickness of an oil film in the bearing unit 2, the resonance of the rotary machine can be avoided at the critical speed, and can also be resultantly safely operated with low vibration value.
