Abstract
In a screw drive, in particular a ball screw drive, a double nut, formed of a pair of individual nuts, is tightened on a threaded spindle and the individual nuts are secured together against relative rotation by a locking member. The locking member is secured within a radially extending recess formed in and bridging the individual nuts. The locking member can be inserted with a certain amount of play into the recess or borehole and then secured within the recess by a cement or similar material so that it cannot be displaced. Various types of locking members can be used, such as locking bolts or threaded bolts. When the locking member is connected into the recess or ball it prevents any rotation of the individual nuts relative to one another.
