Abstract

A clamping system having first and second clamping mechanisms with respective contact faces, that are couplable such that the contact faces press together with a coupling force. The first clamping mechanism has first and second elements and at least three clamping spheres, the first and second elements being twistable relative to one another, and the clamping spheres being mounted on fixed positions of the second element to be rollable along a circular line. The second clamping mechanism has groove guides assigned to the clamping spheres which have helical groove courses in clamping portions. When coupling the clamping mechanisms, by twisting the second element relative to the first, first regions of the clamping spheres are moved to a clamping position which presses the contact faces together via coupling force. When coupling, the clamping spheres in the clamping portions roll over large distances, leading to low wear and activation with reduced force.
