发明名称 BALL SCREW FOR PRODUCING A THREADED NUT OF A BALL SCREW DRIVE
摘要 A method for producing a threaded nut (10, 26) of a screw drive, in particular of a ball screw (7, 24), which threaded nut (10, 26) has, on one axial end, a recess (45) which extends over a circumferential segment and which is open at the end side, wherein said recess (45) is delimited radially by a circumferential wall of the threaded nut (10, 26), and wherein said recess (45) is delimited axially by a base (54) formed on the threaded nut (10, 26), and wherein said recess (45) is delimited in the circumferential direction by a stop surface (47), which is formed on the threaded nut (10, 26), for a projection (44), produced according to the following steps: a blank is deformed in a deformation process by deformation of material so as to form the recess (45), wherein the base (54) and the stop surface (47) and the circumferential wall are integrally connected to one another.
