    • 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.
    • 用于轴向夹持径向对称件的液压夹紧装置具有基本主体,其具有滑动到接收心轴上的纵向轴线。 环形活塞浮动地布置在基体中。 提供了一种用于将环形活塞相对于基体朝向径向对称件移动以夹紧在接收心轴上的闭路液压系统,用于将径向对称的片牢固地夹持在接收心轴上。 布置在环形活塞处的多个补偿楔具有相对于基体的纵向轴线对称延伸的楔形表面。 提供相对于基体的纵向中心轴线径向移动的调节螺钉,用于使补偿楔轴向移位,以将补偿楔固定在夹紧位置。
