摘要： A mechanism converts rotational displacement to linear displacement with ramped driver discoidal elements and ramped driven discoidal elements on a common central axis. The ramped surfaces of the two elements are complementarily shaped and opposed so that, when in contact and completely interengaged, they form an assembly of minimum length. The driver elements are rotated by an external force. The driven elements are allowed to translate along the common axis while being prevented from rotating about the common axis, whereby a rotational displacement of the driver elements by an externally applied force causes the elements to separate by camming action of the interengaged ramp surfaces to produce a linear displacement of the driven elements. A spring is coupled to the driven elements so as to restore the assembly to its minimum length in the absence of the externally applied force.

摘要： A rotational to linear displacement conversion mechanism comprises: an assembly including a plurality of driver discoidal elements and a plurality of driven discoidal elements mounted alternately on a common central axis to form an interleaved stack. Each discoidal element has a ramped surface, the ramped surfaces of adjacent elements being complementarily shaped and opposed so that, when in contact and completely interengaged, they form a stack of minimum length. A coupling means is provided for coupling the driver discoidal elements for rotation together about the axis by an externally applied force while permitting them to translate along the axis. The driven elements are mounted in such a way as to permit translation along the common axis while preventing rotation of the driven elements about the common axis. A rotational displacement of the driver elements by such an externally applied force causes the elements to separate by camming action of their interengaged ramp surfaces so as to produce an extension of the stack corresponding to the cumulative separations of the driver and driven elements. Finally, a resilient bias means is coupled to a driven element in such a way as to restore the assembly to its minimum length in the absence of the externally applied force.
摘要翻译：旋转到线性位移转换机构包括：组件，其包括多个驱动器盘形元件和多个被驱动的盘形元件，交替地安装在公共中心轴上以形成交错堆叠。每个盘状元件具有倾斜表面，相邻元件的倾斜表面互补成形和相对，使得当接触并完全相互接合时，它们形成最小长度的叠层。提供耦合装置，用于通过外部施加的力将驱动器盘状元件联接在一起围绕轴线旋转，同时允许它们沿轴线平移。被驱动元件以允许沿公共轴线平移同时防止被驱动元件围绕公共轴线旋转的方式安装。通过这种外力施加的力使驱动元件的旋转位移通过它们相互接合的斜面的凸轮作用使元件分离，从而产生对应于驱动元件和驱动元件的累积分离的堆的延伸。最后，弹性偏压装置以这样的方式联接到从动元件，以便在没有外部施加的力的情况下将组件恢复到其最小长度。
