Abstract: 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.

Abstract: The disclosure relates to a method for producing a threaded nut of a threaded drive. In a forming process, a sleeve is produced from a steel sheet which is suitable for case-hardening. A flange is integrally formed on the sleeve for welding to a machine part. A welding surface of the flange has a diffusion-inhibiting layer which inhibits the penetration of carbon into the welding surface. The sleeve is case-hardened, and the welding surface is then exposed by removing the diffusion-inhibiting layer. The sleeve can be bonded to a machine part on the exposed welding surface of the sleeve.

Abstract: A profiled nut (1) of a screw drive includes a sleeve (3) produced from sheet steel, has a non-cuttingly formed rolling profile (4) 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 (4). An inner lateral surface of the sleeve (3) having the rolling profile (4) is hardened and has a higher Rockwell hardness. An outer lateral surface of the sleeve (3) is designed such that it can be welded and has a lower Rockwell hardness.

Abstract: Oldham couplings are disclosed, for example, for use in electric camshaft adjusters. The Oldham coupling may include a first outer connecting disk and a second outer connecting disk having axes of rotation extending parallel to each other and a central connecting disk including one or more through-bores. One or more connecting elements may couple the first outer connecting disk to the central connecting disk via the through-bore(s). A sleeve may be arranged in the through-bore(s) such that the connecting element(s) contacts the sleeve and wear of the central connecting disk is reduced. For example, the sleeve may prevent direct contact of the connecting element(s) with the central connecting disk, such as by a spacer or flange. The sleeve may be made of metal, while the central connecting disk may be plastic or metal.
