摘要：
A driving mechanism having a spindle which is provided with a first helical threaded portion having a lefthand direction of rotation and with a second helical threaded portion having a righthand direction of rotation. A pair of spindle guides each engage a respective spindle threaded portion for rotating the spindle and translating the spindle in an axial direction. Each spindle guide has three pairs of runner rollers on a sleeve for centering and supporting the spindle within the sleeves. The three pairs of runner rollers on each sleeve kinematically constrain the six degrees of freedom of the spindle without overconstraint to reduce friction and binding of the spindle in the spindle guides.
