摘要

The arrangement has three balancing bodies (8) arranged in a circular axial aligned retaining groove (7) at an outer collar (3) of a rotor disk (2). Radially inward aligned strips (5) are provided in the collar, where the groove is provided in the strips for the balancing bodies, which engage in the strips and stuck onto the strips. The strips form partial areas of a flange (4) that radially runs on inner side of the collar. The groove has a radial inlet opening that includes an angle of more than 90 degrees and less than 180 degrees, where each body is formed from a cylindrical shaft.
