BEARING FOR DAMPING
PURPOSE:To enable a bearing to be damped even if the angular velocity of a rotating shaft is increased by housing bearing pads in a bearing housing in such a way that they can be displaced to the radial direction, and thereby oscillating the bearing pads to the radial direction by means of an excita...

| description | PURPOSE:To enable a bearing to be damped even if the angular velocity of a rotating shaft is increased by housing bearing pads in a bearing housing in such a way that they can be displaced to the radial direction, and thereby oscillating the bearing pads to the radial direction by means of an excitation device. CONSTITUTION:Bearing pads 24, 25 and 26 are housed in a housing 23, is stopped in whirling and is positioned so that they can thereby be minutely displaced in the radial direction. A rotor 30 is rotatably supported in the inner sides of the bearing pads 24, 25 and 26. The bearing pads 24, 25 and 26 are connected with laminated piezo-electric element type excitation devices 34, 35 and 36 operated by high frequency wave via exciting force amplifiers 31, 32 and 33. The bearing pads 24, 25 and 26 are oscillated by means of exciting actions of the excitation devices 34, 35 and 36 so that fluctuation in pressure is thereby caused in fluid 40 among the rotor 30 and the bearing pads 24, 25 and 26. This thereby allows fluid film force in the shaft center direction to be weakened, and concurrently allows the loading capacity of a bearing to be increased. |
