Abstract
In a centrifugal chamberan elastic rotation shaftand a high-rigidity rotation shaftextend coaxially. When a rotor selected from an angle rotorand a swing rotorwhich have different sizes and shapes is set in the centrifugal chamberan optimal shaft is connected automatically to the selected rotor. The angle rotorhaving a low tendency toward mass eccentricity is supported and rotated by the elastic rotation shaftfor high-speed rotation. The swing rotorhaving a high tendency toward mass eccentricity is supported by the high-rigidity shaftfor low-speed rotation. Rotation torque is transmitted to the swing rotorfrom the elastic rotation shaft.
