Definitions

the above support apparatus 10 uses a structure using the vertical mandrel 11 for rotatably supporting the rotor 1 (single body) by aerostatic bearings.
the structure of the support apparatus 10 is illustrated in FIG. 2 .
the rotor 1 generates hunting vibration due to the pressure variation. If left in this state, the rotor 1 is affected by the hunting vibration, which impairs the accuracy of measuring the amount of imbalance of the rotor 1.
the mandrel 11 includes the vent hole 38 for relieving the pressure varying in the space between the triangular inner surface 26a and the pillar portion 32c with a circular cross section outside. Therefore, as illustrated by the arrows in FIGS. 2 and 5 , the pressure variation occurring in the space, that is, the rising pressure, is relieved out of the space (outside) through the vent hole 38. The falling pressure is compensated by the air of the aerostatic bearings 34 and 35.
