ABSTRACT:
Rectilinear drive apparatus for rapidly and accurately moving a driven component to a desired location with settling of vibration to be achieved immediately after reaching said location; including a frame, a stepping motor drive coupled to the driven component and bearing members slidably mounting the component to the frame. One of the bearing members includes a pair of rails with elongated bearing tracks, one rail mounted to the component and the other to the frame and with the tracks aligned along the direction of component movement. An elongated metal bar, preferably of brass or oil impregnated bronze is slidably mounted in the bearing tracks to slidably support the driven component. A ball nut assembly having a pair of high durometer rubber pads drivingly connects the stepping motor shaft to the driven component.
An X-Y rectilinear drive apparatus includes an upper X and a lower Y drive stage.
