Abstract
A clamp structure and a balancing arrangement for a rotating member by means of the clamp structure, in which a counterweight of predetermined size and weight selected to compensate for an imbalance in the rotating member is securely fastened to the rotating member by the clamp structure which extends over the counterweight to thereby fixedly secure the counterweight onto the external surfaces of the rotating member in a predetermined position; the clamp structure includes a clamping band having inner and outer band end portions overlapping in the installed condition of the clamp structure with a mechanical connection for mechanically connecting the free ends of the clamping band and with a tightening arrangement for tightening the clamping band about the rotating member whereby the mechanical connection and/or the tightening arrangement are located within a circumferential area of the clamping band also containing the counterweight; in one embodiment the tightening arrangement is provided with reinforcing means formed by several side-by-side indentations to enable the use of heavier counterweights and in another embodiment the mechanical connection is provided with a special hook structure to achieve a similar result.
