  • Rotor disk for an exhaust turbocharger, exhaust turbocharger and method for balancing a rotor assembly for an exhaust turbocharger
    Patent number: 10907654
    Abstract: A rotor disk for an exhaust turbocharger is mounted in a housing of the exhaust turbocharger able to rotate about an axis of rotation. The rotor disk has a disk hub comprising a disk back and a disk front remote from the disk back. A plurality of rotor disk blades are formed on the disk hub in a manner extending between the disk back and the disk front. A balancing mark is arranged in a blade channel formed between a first blade of the plurality of rotor disk blades and a second blade, arranged adjacent to the first blade, of the plurality of rotor disk blades. A width of the balancing mark is less than a length of the balancing mark. The disclosure also relates to an exhaust turbocharger comprising such a rotor disk and to a method for balancing a rotor assembly for such an exhaust turbocharger.
