Abstract
The invention relates to a method and a set of balance weights for balancing a rotor particularly of a turbomachine, on which a plurality of balance weights, which are distributed over the periphery, can be arranged for balancing an imbalance. A set of balance weights, in particular plate-shaped weights, with a predetermined number of groups of balance weights, is used for balancing the rotor. Each of the balance weights of every group of balance weights has an identical weight that is assigned to this group and a shape assigned to this group, which differs in basic shape and/or thickness of the balance weights from the balance weights of the other groups.

A method for balancing a rotor of a turbomachine, on which a plurality of balance weights, which are distributed over the periphery, are arranged for equilibrating an imbalance, wherein, a set of plate-shaped balance weights with a predetermined number of groups of balance weights, is used for balancing the rotor, wherein each of the balance weights of every group of balance weights has an identical weight that is assigned to this group and a shape assigned to this group, which differs in basic shape and/or thickness of the balance weights from the balance weights of the other groups, wherein, for balancing the rotor, at least one balance weight from at least one group is arranged at a suitable position on the rotor near the edge or near the periphery thereof, wherein each of the plurality of balance weights have a single through-opening arranged centrally therein.
