Abstract
The invention relates to a holding device for balancing disk-like inertial bodies, which comprises at least two clamping elements (8) centered on a center axis (A), such elements (8) having a respective radial abutment face (34), wherein the clamping elements (8) are provided on a connecting part (10) having at least one elastically deformable portion, which connecting part produces an equal shift of all clamping elements (8) on deformation. A connecting part (10) with the clamping elements (8) is provided on an elastically deformable wall (6), which is constituted by a thin-walled diaphragm (6) extending in a radial plane in relation to the center axis (A), such diaphragm being arranged coaxially in relation to the connecting part (10) and the clamping elements (8). Via a pressure chamber (12) formed in the holding device it is possible for both a vacuum and also gage pressure to be applied in order to deform the diaphragm and accordingly to cause both a radial and also an axial shift of the clamping elements (8) arranged on the diaphragm (6).
