DEVICE FOR AUTOMATIC BALANCING OF ROTORS Russian patent published in 2006 - IPC G01M1/00 

FIELD: balancing technique.

SUBSTANCE: device can be used for automatic dynamic balancing of rotating bodies. Device has casing, which is aligned with rotor and which is filled with working liquid; there are balancing spheres disposed inside casing. Casing is made in form of bushing put on rotor; casing has closed ring-shaped cavity concentrically to rotor Pins with openings at the ends are fixed at ring-shaped bases of cavity periodically along the total perimeter, one to meet another; string is put through and tensed through the openings. As working liquid, the liquid is used which has property of growing viscosity from fluent condition up to complete hardening during process of balancing. Balancing spheres have through holes to be put on parts of string, limited by bases of cavity, for make change incurvature of those parts in space as well as for shifts of string relatively pins and spheres within those parts of string under influence of inertial forces.

EFFECT: widened functional capabilities; improved precision and stability of process of balancing.
