A device (1) for converting rotary movement into axial movement has a spindle (8), a spindle nut (5) surrounding the spindle (8), and a plurality of interposed rollers (7). Each of the rollers has a groove profile (72) corresponding to a thread (81) on the spindle (8), and roller grooves (71) corres
A device (1) for converting rotary movement into axial movement has a spindle (8), a spindle nut (5) surrounding the spindle (8), and a plurality of interposed rollers (7). Each of the rollers has a groove profile (72) corresponding to a thread (81) on the spindle (8), and roller grooves (71) corresponding to spindle grooves (51) formed on the interior of the spindle nut (5). The converter device is driven by a drive unit such as an electric motor (4), either via the elements spindle nut (5) and spindle (8) or, with an interposed connection element, via the rolling elements or rollers (7). The converter device has a reset device with a mechanical energy accumulator (21) and an energy delimiter (22). Energy transfer takes place from the electric motor (4) via the energy delimiter (22) to the energy accumulator (21) connected to a casing (3) or vice versa.
