ABSTRACT:
A device for converting a rotational movement into an axial movement includes driven planetary rollers (10) and a sliding body (5) that can be axially displaced by means of the planetary rollers (10). The planetary rollers (10) are fixed axially in a driven carrier (9), are rotationally mounted and are provided with grooves (11). The grooves (11) of these planetary rollers (10) engage in a thread-type groove of the sliding body (5). In the center of the carrier (9) a bearing body (7) is provided, which engages in the grooves (11). The grooves (11and12) have a mutually adapted gradient, and the planetary rollers (10) and the bearing body (7) engage with one another without slip. Also the carrier (9) and the bearing body (7) engage with one another without slip. The carrier (9) and the bearing body (7) are driven in a rotational relationship, which guarantees that no slip occurs between the planetary rollers (10) and the sliding body (5).
