The movement converter consists of a rolling screw-thread drive (5) with two basic elements (1), (2, 2') arranged coaxially one inside the other and rollers (3) rolling between the two and of a connection member (4) which cannot be displaced in the coordinate axis of the output movement and against which the rotationally moving basic element (1) is axially supported via a rolling-bearing arrangement. The inner basic element not moving rotationally relative to the connection member (4) is of two-piece design, and each of the two individual parts (2, 2') is provided with a rolling screw thread (37, 39) of the same rolling diameter and having the same number of starts but with helix angles of opposite sign with regard to the other individual part. Allocated to the rolling screw thread (37, 39) of each individual part (2, 2') is a roller ring (12, 13) of rollers (15, 16) distributed over the rolling periphery of the individual part. The translational output movement (7) is the sum of the two individual translational relative movements of each of the two individual parts (2, 2') relative to in each case the one-piece basic element (1). |
