Sliding screw arrangement

Abstract

The present invention relates to a sliding screw arrangement (14) for transformation of the rotational movement of a threaded axis (13) into a linear movement of the sliding screw providing minimised tolerances for variations of the screw position in both radial and axial direction and providing minimised friction when moving the sliding screw arrangement along said threaded axis. The screw arrangement consists preferably of two parts (20, 30) and comprises a first resilient part, e.g. a spring (143), to compensate tolerances axial direction and a second resilient part, e.g. a resilient tongue (25), and tracks (28) to compensate tolerances in radial direction. The screw hollowness through which the threaded axis is guided is at its inside is equipped with semi-spheres (21,31) that follow the turn of a thread of the axis.
