    • Actuating means for an adjustable taper mandrel assembly in which the operating means comprises a longitudinally reciprocable rod. The actuating means includes having a first end coupled to the rod and being adapted in response to actuation of said arm to execute a linear reciprocating motion from a datum position at an extremity of said motion. The arm is mounted intermediate its ends on floating fulcrum means which includes adjustment means for varying the position of the fulcrum with respect to the datum position of said first arm end and in a plane containing or parallel to the said datum position. The arrangement is such that the throw of the longitudinal rod can be varied by operation of said adjustment means while maintaining said one extremity of said motion of said first end in said datum position, thereby varying the taper imparted to the mandrel assembly in its expanded position.
    • 用于可调节锥形心轴组件的致动装置,其中操作装置包括纵向往复运动的杆。 致动装置包括具有联接到杆的第一端并响应于所述臂的致动而适于执行从所述运动的末端处的基准位置的线性往复运动。 手臂安装在其末端的浮动支点装置上,该浮动支点装置包括调节装置,用于相对于所述第一臂端的基准位置和包含或平行于所述基准位置的平面改变支点的位置。 该布置使得可以通过所述调节装置的操作来改变纵向杆的投掷,同时将所述第一端的所述运动的所述一个末端保持在所述基准位置,从而改变被赋予到心轴组件处于其展开位置的锥度 。
