Abstract:
1. A clamping system for detachably connecting two parts, of which one part exhibits a hollow shaft, and the other part exhibits a receiving portion for receiving the hollow shaft with a precise fit, the clamping system comprising: a main body configured to be concentrically arranged in the receiving portion of the other part, the main body configured to extend into the hollow shaft of the one part when the two parts are joined together, the main body bearing two clamping bodies, the two clamping bodies adjustable in a diametrically opposed manner between a release position and a clamping position; and an ejector held so as to be axially adjustable by a defined ejection stroke in a centric through-bore in the main body, the two clamping bodies configured to run up against a surface of the ejector when the clamping bodies are in the release position, the two clamping bodies configured to subject the one part to a pressing force acting in a pressing direction toward the other part when the two clamping bodies are in the clamping position and when the main body is concentrically arranged in the receiving portion of the other part, the two clamping bodies configured to subject the one part to an ejection force acting in an ejection direction away from the other part by way of the ejector when the two clamping bodies are in the release position and when the main body is concentrically arranged in the receiving portion of the other part, and the ejector comprising a rotating body, the rotating body detachably anchored directly in a centric through-bore formed in the main body with axial play corresponding to the defined ejection stroke.
