Title: Dynamic pressure type gas bearing device
Inventor: UNO SHUETSU
IPC: F16C17/03
Filed: 1989-10-06
Abstract: PURPOSE:To suppress resonance of a rotor as well as unstable vibration by setting a movable side magnet on a base end of a moving type pivot, and by forming a structure in which magnetic repulsion caused by magnets on the movable side and fixed side, is converted into pad pressing power, through the moving type pivot. CONSTITUTION:When a generator rotor 4 is rotated, a gaseous film pressure is generated in a bearing gap 5 between the rotor 4 and a pad 1 through the dynamic pressure actuation of gas. The gaseous film pressure is increased, while the dynamic pressure type pivot 10 is lifted outwards in a direction of the diameter of the rotor 4. A movable side magnet 12 approachs a fixed side magnet 17, and magnetic repulsion caused by both of the magnets 12, 17 is increased, until the magnetic repulsion balances with the gaseous film pressure. Since the magnetic repulsion is increased according to the rotation of the rotor 4, pad pressing power given by the pivot 10 to the upper pad 1 is increased, and resonance of the rotor 4 and unstable vibration can thus be suppressed.
