WEIGHT TO BALANCE ROTORS OF TURBOMACHINES Russian patent published in 2002 - IPC

FIELD: balancing equipment. SUBSTANCE: given weight is intended for use in the capacity of correction mass to balance rotors. Weight is made up of two parts coming in the form of cylinders forming summary correction mass. Both cylinders have identical central threaded holes and slotted grooves in faces, thread on cylindrical surfaces. First cylinder mounted near bottom of seat of rotor has smaller diameter but greater mass, thread pitch on cylindrical surface of second cylinder is smaller than thread pitch of first cylinder. Such weight makes it possible to install it in seat of rotor through plugged hole in stator and to fix it reliably in seat independent of disturbances caused by running. EFFECT: enhanced handling and functional convenience. 1 dwg
