Abstract
The invention relates to a screw mechanism comprised of a screw shaft (), a screw nut () and rolling bodies. When the screw mechanism is subjected to a high static load, the forces are transmitted from the screw shaft () to the screw nut () by means of the rolling bodies. As the contact surfaces between the rolling bodies, the screw nut () and the screw shaft () are very small, only relatively weak forces can be transmitted. In order to adapt the screw mechanism to high static loads, using simple construction measures, the surface of the screw shaft () between the grooves () of the rolling bodies is provided with locking structures which can be form-fittingly connected with complementary locking structures of locking elements () which are moveable essentially transversally to the axis of the screw shaft ().
