  • Rolling-body screw drive and method of assembling the same
    Publication number: 20010023618
    Abstract: A rolling-body screw drive (10a) comprises a threaded spindle (12a) with a spindle axis (S), and a double nut (14a) which runs on the threaded spindle (12a) and has two separately formed individual nuts (16a, 18a) which are connected essentially rigidly to one another in the direction of the spindle axis (S). In this case, for setting a desired level of play or a desired prestressing in relation to the threaded spindle (12a), the two individual nuts (16a, 18a) can be rotated continuously relative to one another about the spindle axis (S) and can be secured in any desired rotary position relative to one another corresponding to the desired level of play or the desired prestressing.
