| 20120040126 | Blank of a Machine Component Comprising Teeth, and Method of Producing Such a Machine Component - A blank of a machine component comprising teeth, and a method of producing a corresponding machine component. The blank has a surface provided to constitute outside-face end regions of the teeth, and has indentations, which are preferably realized by a forming operation, boundaries of the indentations constituting edge regions of the surface. In the alteration of the blank for the purpose of realizing the machine component, the teeth can be realized in such a way that remaining regions of the indentations constitute chamfers of tooth flanks of the teeth. Burr strands, which would have to be removed in a further operation, can thereby be prevented. | 02-16-2012 |
| 20120032552 | Rotor and Process for Producing the Same - The invention relates to a rotor that exhibits a rotor shaft, by which a rotor axis is defined, and also a core stack that is arranged around the rotor shaft along a longitudinal portion of the rotor axis. Along the longitudinal portion the rotor shaft exhibits a first surface region, the shape of which describes a circular cylinder, and also a second surface region which is constituted by structural elements that with respect to the rotor axis rise radially outwardly above the first surface region. For the purpose of producing the rotor, the core stack can be pushed over the rotor shaft and in the process can be pushed against the structural elements) in such a manner that it is deformed and by this means a positive connection between the rotor shaft and the core stack is generated. In this way, in particularly simple manner in terms of production engineering a reliable and torsion-proof connection between the core stack and the rotor shaft can be formed. | 02-09-2012 |
