Abstract
A method is disclosed for setting an axial preload force of a roller screw drive rotatably mounted in a housing. The housing is split transversely into a first and a second housing part. The roller screw drive is inserted with two axially spaced bearings into the second housing part. An axial preload force is applied which is transmitted from the first bearing via the roller screw drive to the second bearing. An axial load spacing between the bearing supporting surface of the first bearing and a second housing edge of the second housing part is measured. An adjusting nut is screwed into the first housing part until an axial adjustable spacing is the same size as the measured axial load spacing. The adjusting nut is then secured in place in the first housing part, and the two housing parts are connected to one another.
