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.

摘要： A pressurized or hydraulic clamp, with piston reset, for securing tools or workpieces, such as grinding wheels, milling tools, and the like, to a shaft. By pressurizing with a hydraulic fluid, a floating piston is pressed out of the clamping unit to hold the workpieces or tools against a support. In order to retract the piston when the hydraulic pressure is released, the circular piston is provided with a bead on its outside or inside, depending upon the application; the bead is connected to one or more springs. The springs, which are pre-tensioned in the starting position, and are further tensioned when the piston is driven out, automatically reset the piston when the pressure is released.
