Abstract

An actuator having a planetary screw drive (PSD), in particular for the operation of a clutch of a motor vehicle, wherein a plurality of planetary rollers which mesh with a ring gear that encircles the planetary rollers are in contact with a spindle, where the planetary rollers are positioned at both ends in a planetary roller carrier and the planet carriers are supported non-rotatingly in a sleeve that encircles the ring gear and points radially inward at both ends, wherein the sleeve and the planetary carriers supported in it are axially fixed and connected non-rotatingly to a rotor of a drive and are drivable around an axis of rotation, the spindle is supported non-rotatingly and the spindle performs an axial stroke when the rotor and the planetary carriers supported in the sleeve rotate, is provided.
