    Abstract: A method for manufacturing a gear includes providing a rim gear, a hub and a core wherein the core is annular and has a core forging temperature below a hot hardness temperature of the rim gear and the hub. The rim gear and the hub are rotated about an axis relative to the core. During the relative rotation, the rim gear and the hub are in contact with the core to generate friction heat to raise an interface temperature of the core to the core forging temperature. The hub is driven into the core to upset a first portion of the core into an outer annular groove defined in a first faying surface of the hub. The rim gear is driven over the core to upset a second portion of the core into an inner annular groove defined in a second faying surface of the rim gear.

    Abstract: Die Erfindung betrifft ein Verfahren sowie eine Anlage zur Herstellung und Weiterverarbeitung von Werkstücken (1) aus einer Materialplatte mittels eines Lasers. Als erster Verfahrensschritt wird die Materialpatte auf einem Träger (3) befestigt, wobei die Befestigungsstellen (11) derart gewählt werden, dass nach dem Ausschneiden ein die Werkstücke (1) umgebender Rahmen (7) entfernt werden kann. Die Werkstücke (1) verbleiben aber am Träger (3) befestigt und können dann weiterverarbeitet, zum Beispiel beschichtet werden. Nach der Weiterverarbeitung werden die Werkstücke (1) durch mechanische, thermische oder chemische Beanspruchung vom Träger (3) gelöst. Da die Werkstücke (1) nach dem Ausschneiden auf dem Träger (3) verbleiben, müssen sie für die Weiterverarbeitung nicht mehr einzeln neu positioniert werden. Eine Anlage, welche nach dem erfindungsgemässen Verfahren Werkstücke (1) herstellt, kann den Träger (3) als ganzes transportieren und positionieren. Dies bedeutet eine effektivere Handhabung der Werkstücke (1), was zu Zeitersparnis führt und somit zu einer Senkung der Herstellungskosten der Werkstücke (1) beiträgt.
