Abstract:
Device for the centric and/or imbalance-free holding of rotating parts, such as a clamping chuck for a workpiece, or a clamping sleeve for a cool, or a tool on a spindle of a turning machine by means of centric holding surfaces,wherein device holding surfaces are provided with profiles which are coordinated with one another in pairs and which each have three or six wedges which rise over imaginary cylindrical reference surfaces radially toward the outside or toward the inside and each again drop steeply back to the reference surfaces, are offset by the same angles in the circumferential direction and have a joining gap in a joining position,wherein the surface of the wedges follow the course of a logarithmic spiral, so that the surfaces of the wedges fit flatly against one another in all angular positions thereby effecting a precisely centered fit in the holding device,further wherein angular positions of eccentricities or unbalanced masses of two respective parts to be connected which are known with respect to a starting position, are joined in such a mutual angular position and rotated into frictional engagement such that the eccentricities or unbalanced masses are substantially diametrically opposite with respect to the axis of rotation of the spindle, so that said eccentricities or unbalanced masses are optimally compensated.
