THE ABSTRACT

The autobalancing device can be used in a mechanical engineering for balancing of the rotors of centrifugal machines on the speeds of rotations, which is higher the critical one.

The problem of the invention is a diminution of sensitivity of corrective mass to the changing of an angular speed of rotation of a rotor.

The problem is decided so that in a device, that contains corrective mass, which is installed with a possibility to make turns around an axis of the shaft and axis, which is perpendicular to it, and which center of masses does not coincide with center of rotation, the mass is fulfilled as a body with identical principal axial moments of inertia concerning a center of rotation and is install with a possibility of turns around of two axes, which directed not along an axis of the shaft. The body, which has identical principal axial moments of inertia, can be carried out as three jointed under a right angle of identical pendulums, rods, bodies of rotations, in which the center of rotation coincides a point of junction, or like a half-ball and half-sphere, in which the center of rotation coincides a center of a half-ball or half-sphere.
