Abstract
PURPOSE:To achieve metering in safety and with high precision without limitations of the shape and weight of a rotating body to be tested, by fitting said body to be tested freely slantably and by providing a radial bearing which has an oscillation attenuating machine at the lower end of a hard shaft. CONSTITUTION:To a body 21 of a revolution to be tested, a static pressure spherical-surface bearing 23 is fitted through a metal fitting 22 shaped so that the center of gravity of the rotary part is positioned slightly below the center of the spherical surface of the static-pressure spherical-surface bearing 23, which is so mounted on a cylindrical spherical-surface pedestal 24 that it can rotate and slant. The spherical-surface pedestal 24 is fixed on a box-shpaed trestle fixed to a base board 25, and runs through the bearing 23 without contacting and the upper terminal of a suspended hard shaft 27 is stuck at the shaft center position. Then, the lower terminal of the shaft 27 is pivoted in a radius direction by a radial bearing 28, which has an oscillation attenuation device 29, so that it is displaced.
