Rotor for a turbomachine, turbomachine, and method for balancing a rotor of a turbomachine

A rotor for a turbomachine, comprising a rotor nose having an integral balancing geometry for material removal for the purpose of balancing, wherein the balancing geometry has a first balancing portion having a first center of mass S1 and a second balancing portion having a second center of mass S2, wherein the first center of mass S1 and the second center of mass S2 are spaced apart axially, wherein a maximum radial extent R1max of the first balancing portion is less than a maximum radial extent R2max of the second balancing portion,

• wherein the first balancing portion has an axial end surface for axial material removal for the purpose of balancing the rotor as an individual part, and
• wherein the second balancing portion has an axial end surface for axial material removal for the purpose of balancing a rotating assembly of a turbomachine having the rotor.

A rotor for a turbomachine, comprising a rotor nose having an integral balancing geometry for material removal for the purpose of balancing, wherein the balancing geometry has an outer surface for a first material removal for the purpose of balancing, and wherein the balancing geometry has an inner surface for a second material removal for the purpose of balancing, wherein the outer surface is at a greater radial distance from an axis of rotation of the rotor than the inner surface.
