Abstract
A screw drive with circulating balls, comprising a spindle, a spindle nut provided with internal thread, balls arranged in channels for balls formed between the internal thread and the spindle and intended to transmit axial forces between the spindle and the spindle nut, and further comprising return devices for returning the balls from the outlet of the ball channels to the entrance thereto, and in turn also means for compensating the clearance and, respectively, for adjusting a pre-tension between the spindle and the spindle nut, characterized in that a spindle nut (38) is provided in one piece, that is to say it is not divided transversely with respect to the axial direction, but having at least one compensation slot (74) which it runs in the longitudinal direction, and a tensioning device (40, 62) that receives the spindle nut (38), guarantees its roundness and makes it essentially support all the b waves (52) located in the internal thread (10), the cross section of the internal thread (at 80) being rounded only in the places where the internal thread (48) opens into the compensation groove (74).
