Abstract
A device for converting rotational movement into axial movement includes planetary rollers driven by a drive shaft projecting from a drive device and maintained peripherally at a same distance, in addition to a push body axially displaced by the planetary rollers. These planetary rollers are peripherally fixed on a support which is driven around the axis thereof, the rollers being rotationally mounted and provided with peripheral grooves or threaded grooves; the support is connected in a fixed manner to the drive shaft rotating around its axis; the planetary rollers engage in at least one thread-like groove of the push body that is displaced along the axis of the support by means of their peripheral grooves or threaded grooves. The support drives the planetary rollers; the push body is embodied as a hollow body encompassing the planetary rollers; a bearing body that has peripheral bearing grooves or threaded grooves and that can rotate independently around its axis relative to the drive shafts and concentrically inside the planetary rollers is provided in the center of the support.
