    • The invention relates to a clamping device for a rod which moves in an axial translatory or rotating manner. Said clamping device comprises a housing, a clamping sleeve which is axially fixed therein, a tensioning piston which can be displaced in the housing embodied as a cylinder, and a spring device for pre-tensioning the piston in the direction of the clamping sleeve in the locking state. Said spring device includes at least one helical plate spring which, in the event of a fracture, maintains the holding force and the dynamic course of the same. In one embodiment, the at least one helical plate spring is coaxially arranged in relation to the rod. In another embodiment, a plurality of helical plate springs are arranged on the circumference of the rod such that they are parallel with the axis thereof, for distribution of a pre-tensioning force acting on the spring device.
    • 本发明涉及一种用于以轴向平移或旋转方式移动的杆的夹紧装置。 所述夹紧装置包括壳体,其轴向固定在其中的夹紧套筒,可在壳体中被移动的张紧活塞,其被实施为气缸;以及弹簧装置,用于在所述夹紧套筒的方向上预张紧所述活塞 锁定状态。 所述弹簧装置包括至少一个螺旋板弹簧,其在断裂的情况下保持保持力及其动态过程。 在一个实施例中,至少一个螺旋板簧相对于杆同轴布置。 在另一个实施例中,多个螺旋板弹簧布置在杆的圆周上,使得它们与其轴线平行,用于分配作用在弹簧装置上的预张力。
