Abstract
An actuating mechanism has a main rotational drive and a roller screw mechanism coupled to the main rotational drive. The roller screw mechanism has a screw, a nut, and a plurality of rollers. One of the screw and the nut is coupled to the main rotational drive, while the other is movable relative to the rollers both translationally and rotationally. The roller screw mechanism also has an annular guide for circumferential and axial retention of the rollers. The annular guide contains a cylindrical sleeve that extends axially outward from one of the annular heels beyond the nut. The screw extends into a bore of the sleeve, and the sleeve is coupled to a secondary rotational drive.
