DEVICE FOR OBJECT BALANCING Russian patent published in 2000 - IPC

FIELD: balancing equipment. SUBSTANCE: invention can find use for balancing of rotors, shafts, wheels, turbines and other objects requiring balancing. Proposed device includes body housing shaft interacting with drive, mounted with its ends in antifriction bearings for displacement relative to shaft axis and composed of two parts placed on both sides of object, centering mechanisms positioned on both sides of object and aid registering balanced position of object. Device also has aid measuring unbalance. Ends of shaft have shape of part of sphere. Antifriction bearings are supplemented with mechanisms returning shaft to initial position. Each centering mechanism has two mutually perpendicular lead screws with weights mounted on them for movement along screws, four rollers kinematically coupled to ends of screws and centering ring placed coaxially to shaft on body and having profiled surface on outside at level of rollers. Rollers are set with clearance relative to centering rings. EFFECT: simplified balancing process and increased precision of it. 4 cl, 2 dwg
