Shaft with rounded projections around its circumference, especially for an electromotor, is shaped by two tools with structured surfaces which compress the shaft surface while hot or cold

The shaft (2) with external rounded structures around its circumference, especially for an electromotor, has a consolidated section (8) where the surface material is compressed and shaped by the outer surfaces (5,5') of two tools (3,4) of a shaft production assembly (1). The tool surfaces, with...

Beschreibung
Zusammenfassung:	The shaft (2) with external rounded structures around its circumference, especially for an electromotor, has a consolidated section (8) where the surface material is compressed and shaped by the outer surfaces (5,5') of two tools (3,4) of a shaft production assembly (1). The tool surfaces, with peaks (6) and valleys (7), are smoothed to give a constant penetration depth into the shaft surface. The shaft surface shaping can be with or without heat. Eine Welle (2), insbesondere eine Welle für einen Elektromotor, weist einen Befestigungsabschnitt (8) auf, der einen über den Umfang veränderlichen Durchmesser aufweist. Dabei ist das Material der Welle (2) zumindest im Bereich einer Oberfläche (10) des Befestigungsabschnittes (8) verdichtet. Außerdem ist ein Verfahren zur Herstellung solch einer Welle (2) angegeben.
