Abstract
A clamping system for detachably connecting two parts, one part has a hollow shaft and the other part has a receiving portion for receiving the hollow shaft with a precise fit, comprising: a main body to be arranged concentrically in the receiving portion, extends into the hollow shaft when the two parts are joined to one another, and bears two clamping bodies, operable in a diametrically opposed manner between release and clamping positions, and comprising an ejector axially adjustable by a defined ejection stroke in a centric through-bore in the main body, the clamping bodies subject the one part to a pressing force in the clamping position, and in the release position subject the one part to an ejection force, the ejector formed from a body of revolution, which is detachably anchored directly in a centric through-bore in the main body with axial play corresponding to the ejection stroke.
