ABSTRACT:
A chuck with radially adjustable base jaws and exchangeable clamping jaws is provided. The toothings of the base jaws intermesh with respective toothings of the clamping jaws. The base jaws and the clamping jaws are coupled by respective keys which are adjustable relative to one another by an amount corresponding at least to the height of the intermeshing toothings. The adjustment is carried out by a clamp bolt which extends through the shaft of the key and which is provided with a conical clamping surface. The clamp bolt is supported at a rotatably mounted threaded elements or spindle such that the key may be adjusted in the axial direction of the key shaft by the rotation of the threaded element or spindle due to the cooperation of respective counter surfaces provided at the threaded element or spindle with the clamping surfaces of the clamp bolt. Due to this arrangement it is possible to connect and release respective clamping jaws from the base jaws in a very short period of time. Furthermore, an extremely high stability of the base jaws-clamping jaws-arrangement is achieved so that very high forces may be transmitted.
