Description

Die neuzeitliche Fertigungsmethode von mit einem Kronenrad ausgestatteten Rotoren, insbesondere für Innenläuferzahnradpumpen. geht dahin das Kronenrad nicht mehr zu fräsen, sondern im Fließpressverfahren kalt zu schlagen. Hieraus ergeben sich Schwierigkeiten, die vor allem materialbedingt sind. ■The modern production method of equipped with a crown wheel Rotors, especially for internal rotor gear pumps. the face gear is no longer milled, but in the extrusion process to beat cold. This gives rise to difficulties that are mainly due to the material. ■

Aus Gründen des Verschleißes ist es erforderlich die Rotorwelle, auf der .Oberfläche induktiv zu härt.en. Die Rotorwelle'muss daher aus einem Werkstoff mit höherem Kohlenstoffgehalt von beispielsweise '0,6$ bestehen, der sich leicht oberflächenhärten, aber nicht fließ-. pressen lässt.

Werkstoff verwendet werden/ der einen Kohlenstoff gehalt von Mayimsl :'.For reasons of wear, it is necessary to induce hardening of the rotor shaft on the surface. The rotor shaft must therefore consist of a material with a higher carbon content of, for example, 0.6 $, which easily hardens on the surface, but does not flow. can be pressed. Only one can do pure extrusion of the face gear. Material used / with a carbon content of Mayimsl: '.

Da sich ein Werkstoff mit niedrigem Kohlenstoffgehalt nicht ohne eine vorherige Aufkohlungrhärten lässt, musste zwischen .den beiden Werkstoffen ein Kompromiß geschlossen werden, der entweder die Güte des Rotors beeinträchtigt oder zusätzliche Arbeitsgänge erfordert.Since a material with a low carbon content cannot be hardened without prior carburization, there had to be between the two Materials a compromise must be made, either the quality of the rotor or requires additional operations.
