The disclosure relates to a threaded nut of a ball screw, the threaded nut having an inner sleeve made of sheet metal and an outer sleeve made of sheet metal, which are nested axially in one another to form a nut sleeve. The nut sleeve is provided with a thread, which is formed helically about a longitudinal axis of the threaded nut and which forms, on the inner circumference of the nut sleeve, a ball groove wound helically about the longitudinal axis of the threaded nut and, and on the outer circumference of the nut sleeve, a helically wound outer ridge.

Threaded nut of a ball screw and method for producing same

The disclosure relates to a threaded nut of a ball screw drive. The threaded nut includes an inner sleeve made of sheet metal and an outer sleeve made of sheet metal. The inner and outer sleeves are nested axially in one another to form a nut sleeve. A thread of the nut sleeve is helically wound about a longitudinal axis of the threaded nut and forms a ball groove on the inner circumference of the inner sleeve. The outer sleeve is provided along the thread with at least one outer hole into which material of the inner sleeve is molded.

Threaded nut of a ball screw drive, and method for producing same

A profiled nut () of a screw drive includes a sleeve () produced from sheet steel, has a non-cuttingly formed rolling profile () on the inner circumference for rolling contact with rolling bodies and is hardened in a heat treatment method at least in the region of the rolling profile (). An inner lateral surface of the sleeve () having the rolling profile () is hardened and has a higher Rockwell hardness. An outer lateral surface of the sleeve () is designed such that it can be welded and has a lower Rockwell hardness.
