Measuring the rotational inertia of the heavy air bearings

摘要

The present invention relates to an air bearing for the rotational inertia of the measured weights,; As provided in the bearing 10 which is supported at a plurality of points on the cylinder once the large diameter of the object to be measured in the entire axial member (1); Bearing 10 is incorporated in the processing on the contact face of the segmented into two or more equal parts of a rigid metal member divided body member (20,21,22.) And the partition member body (20,21,22.) the air inlet pipe for the external air inlet of branched flow paths 13 and connected to the branched flow path 13 and the fluid to form a discharge path ball in an arc connection surface (S) on with the axial member (1) (11 ) to configure the bearing body 12 a; And characterized in that to minimize friction between the axial member (1) with the connection surface (S) and a compressed air connection open to the surface (S);; Rotational inertia air bearing for the measurement of in heavy paper has increased the precision and ease of by the measurement of the rotational inertia Motor treatment in the formation of a kind of air cushion state in the conventional support configuration by differently jetting compressed air from below experimental and that for the purpose.
