摘要： A hydraulic clamping device for the axial clamping of bodies of rotation, especially tools, onto a revolving mandrel is provided. It has a base body fixed to a mandrel and a rotary piston which is suspended in a floating manner inside the base body and is axially slidable relative to the base body via a closed-circuit hydraulic system and setscrews. The tool is tightly clamped in an axial direction. In order to improve the axial rigidity of the hydraulic clamping device, to provide a fast and directed adjustment of the concentricity during the clamping of the tool inside the device and to provide a radial freedom of play during operation, a sleeve fastened to the mandrel is provided to which the base body is attached. The sleeve is equipped with an elastic flange, a first face of which is engaged by the rotary piston and a second face of which is abuttable against said tool.

摘要： A hydraulic clamping device for axially clamping pieces of radial symmetry has a base body with a longitudinal axis slipped onto a receiving mandrel. An annular piston is floatingly arranged in the base body. A closed circuit hydraulic system for displacing the annular piston relative to the base body toward a piece of radial symmetry to be clamped on the receiving mandrel is provided for securely clamping the piece of radial symmetry on the receiving mandrel. A plurality of compensation wedges arranged at the annular piston have wedge surfaces extending symmetrically to the longitudinal axis of the base body. Adjusting screws that are radially displaceable relative to the longitudinal center axis of the base body are provided for displacing the compensation wedges axially in order to secure the compensation wedges in a clamping position.

摘要： A withdrawing device for withdrawing a roller bearing from an arbor is comprised of a hollow body having a withdrawal sleeve and a spindle that axially penetrates the hollow body. The withdrawal sleeve has axially extending slots defining therebetween tongues with ends that widen radially outwardly in a cone shape with a conical outer mantle surface. The free ends constitute withdrawal elements. A clamping sleeve is axially slidably and rotatably connected to the hollow body. At one end thereof the clamping sleeve has a conical inner mantle surface mating with the conical outer mantle surface of the free ends. The clamping sleeve is comprised of a pressure sleeve and an adjusting sleeve, whereby the pressure sleeve comprises the conical inner mantle surface and the adjusting sleeve is rotatably connected to the hollow body and rotatably and axially fixedly connected to the pressure springs.

摘要： The invention relates to a hydraulic clamping means, in particular, a clamping nut, for mutual axial clamping of two workpiece sections or machine parts, in particular, a collet and a chuck, comprising an annular housing engaging one workpiece section or machine part, at least one pressure chamber arranged in the housing and filled with hydraulic medium, a pressure screw screwable into this chamber, and an annular pressure area provided in the housing and connected to the pressure chamber, with an annular piston engaging the other workpiece section or machine part axially displaceable in the annular pressure area. To enable direct clamping of two workpiece sections or machine parts in the clamping means itself, the housing and the annular piston comprise clamping surfaces which are directed inwardly and towards one another and each engage one of the workpiece sections or machine parts respectively, and the pressure area, the housing and the annular piston are so constructed and arranged in relation to one another that increasing pressure causes an axial relative displacement of the clamping surfaces towards one another.
