A description is given of a balancing disc arrangement (11) for balancing a rotatable body, such as for example of a rotary machine (1), and a method for correcting the balance of a rotary machine. A plurality of annular balancing discs (13) are fixed on a shaft (3) of the rotatable body, in order to rotate synchronously with said body about a central axis (31). The plurality of annular balancing discs (13) may in this case be arranged in a stack along the central axis (31). Each of the annular balancing discs (13) has an off-centre clearance (17), and so when the annular balancing disc (13) rotates about the central axis it creates an unbalance which can at least partially compensate for an existing unbalance of the rotatable body. The degree of compensatory unbalance can be set by the size of the clearances (17) that are provided in the annular balancing disc (13) and the orientation in relation to one another of the annular balancing discs (13) provided with the clearances (17). Low-cost, easy and precise balancing is made possible. |
