PROCEDURE AND DEVICE FOR ROTOR BALANCING Russian patent published in 2011 - IPC G01M1/16 

FIELD: machine building.

SUBSTANCE: balanced rotor and balancing body are imparted to motion in plane perpendicular to their common axis. There are measured amplitudes and phases of occurring angular oscillations of a balanced rotor and there are determined values of unbalance and angular coordinate of its location. Also, force equal in value, but opposite in direction to centripetal force of common weight of the balanced rotor and the balance body is imparted to their common axis at each moment of time in plane of circular motion of centre of common weight of the balance rotor and balance body. The device consists of a bed, of a balance platform suspended on the bed on flexible elements, of a vertical shaft with the balanced rotor coaxially secured at one end, also, its another end is installed in the flexible supports in centre of the balance platform perpendicular to its plane, of a drive of circular motion and of a measuring unit. At least three flexible elements are similar, are installed vertically and are rigidly secured with their one ends on the balance platform in points equidistant relative to one another and from its centre, while with their other ends they are rigidly fixed on the bed in points in one horizontal plane. The drive of the circular motion corresponds to an electric engine mounted on the balance platform in its centre so, that axis of an electric engine shaft is perpendicular to plane of the platform. An inertia weight with specified concentricity is secured on the shaft of the electric engine. Centre of this weight is positioned in horizontal plane passing through centre of common weight of the balance platform with structure elements set on it.

EFFECT: upgraded accuracy of balancing.
