ABSTRACT:
Method for the production of a spindle nut (3) of a spherical thread drive mechanism, whereby the spindle nut (3) has at least one screw-shaped track (4) formed as a single piece on its inner circumference, whose threads (38) are limited by shoulders (6). The shoulder (6) is interrupted by a deflecting recess (23) at at least one deflecting position, in order to deflect balls (13) out of one thread into an adjacent thread (38). The method includes locating a tool arbor (56) in a hollow blank (57), whereby the tool arbor (56) has on its outer circumference a counter profile of the screw-shaped track (4) and a projecting part (59) for each deflecting recess. A tool operates on and reshapes the blank (57) from the exterior by exercising radial forces (F), whereby during the reshaping process the inner circumferential surface of the blank (57) is shaped according to the counter profile and to the projecting part (59) of the tool arbor (56) such that the screw-shaped track (4) and the deflecting recess (23) are formed.
