Title: Gas bearing for improvement disk
Inventor: MOMOSE YUTAKA
IPC: F16C17/08
Filed: 2002-07-15
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem wherein even if a sealed space formed at a shaft end part has high gas-tightness, gas slightly leaks to be unable to bear load in a gravity direction and an anti-gravity direction with a gas bearing established in a radial direction by keeping radial clearance between a fixed shaft and a moving shaft as little as possible and securing sufficient bearing length for securing large force to return both shafts to the center when the both shaft are decentered, for bearing radial load of the fixed shaft and the moving shaft while keeping shaft run out small.  <P>SOLUTION: Load in the gravity direction is born on a ball spherical surface center of a rotational moving shaft with a little rotational torque, movement in the anti-gravity direction is immediately restored by pressure difference between the sealed space and atmosphere, and magnetic attraction force between a ball support member and a moving shaft end surface bears load in the gravity direction and the anti-gravity direction. A surface of the moving shaft is hardened by surface hardening film treatment such as diamond like processing to prevent seizure even if load acts on the gas bearing and metals contact due to eccentricity of the fixed shaft and the moving shaft.  <P>COPYRIGHT: (C)2004,JPO
