Abstract: A nut assembly comprised of a nut body (1a) and a pressure disk (2a) and a method for producing the same. The nut body has a drive portion, such as a polygonal portion, for engaging with a tool and an abutment region that can be brought into contact with the supporting surface of the pressure disk arranged on the nut body in a non-releasable manner. The pressure disk has a central opening into which a neck formed on the nut extends axially at least in part, and the neck has a projection which radially overlaps or engages the thrust ring in order to form the non-releaseable connection.

Abstract: A method of producing a built shaft in which at least one part, particularly a cam, is mounted on the shaft, particularly a camshaft, includes inserting the shaft into an opening of the part. Before mounting the part, the shaft is stretched by a stretching and tightening device such that an original diameter in the area of at least one fastening location is reduced to a stretched diameter. The part is slid onto the shaft and up to the fastening location. The stretching and tightening device is then loosened to enable the diameter of the shaft to enlarge once more towards its original diameter. The part is firmly fastened at the fastening location by an interference fit in both an axial and rotationally fixed manner.

Abstract: The invention relates to both nut assemblies and methods for producing the same. Said nut assemblies consist of a nut body (1a) and a pressure disk (2a). The nut body has a drive portion, such as a polygonal portion, for engaging with a tool and an abutment region that can be brought into contact with the supporting surface of the pressure disk arranged on the nut body in a captive manner. The pressure disk has a central opening into which a neck formed on the nut extends axially at least in part. The neck has a projection for forming a captive connection. This projection radially overlaps or engages the thrust ring.

Abstract: A method for producing an annular element having an inner toothing, especially a sliding sleeve. An outlet ring element can be arranged in an extrusion device which includes an annular matrix element with an inner bore hole, a sleeve stamping device which is arranged therein and has first and second annular sleeve stamping elements which can be moved in relation to each other in the inner bore hole, and an inner stamping device having first and second inner stamping elements and first and second partial regions which are interspaced in the circumferential direction. When the inner stamping device is closed, the partial regions form cavities for producing the inner toothing. The outlet ring element is arranged between the first and second inner stamping elements and is measured in such a way that when closing the sleeve stamping device, material from the outlet ring element flows into the cavities for the formation of the inner toothing.
