Abstract

See full text

A method for producing a threaded nut of a threaded drive, includes the following steps: a sleeve is produced from a steel sheet which is suitable for case-hardening; a rolling profile for a rolling contact with rolling bodies is molded on the inner circumference of the sleeve, said rolling profile being wound in a helical manner about the longitudinal axis of the sleeve; a flange is welded to the end face of the sleeve; the flange is provided with a welding surface on the flange end face facing away from the sleeve for welding to a machine part; the welding surface initially has a diffusion-inhibiting layer which inhibits the penetration of carbon; and the welding surface is exposed by removing the diffusion-inhibiting layer after case-hardening the threaded nut. A threaded nut produced according to the method can be part of a ball screw drive, the flange of which can be welded to a provided machine part by the user.
