ABSTRACT:
A screw drive with a spindle and a frame surrounding the spindle. The frame includes head and foot plates through which the spindle passes, and the screw drive includes at least one collar bearing arranged eccentrically to the spindle axis and supported by resilient frame parts. An annular bead or toroid arranged on the inner ring of the bearing engages in the thread of the spindle, whereby the collar bearing is pivotal about an axis located in the direction of the eccentricity thereof with respect to the spindle axis. The collar bearing surrounding the spindle is journalled at right angles to the spindle axis in two leaf springs which either form oppositely located longitudinal side walls of the frame, or which are located in the plane of the longitudinal side walls.
