Description
Die Erfindung betrifft einen Wellenflansch einer landwirtschaftlichen Erntemaschine nach dem Oberbegriff des Anspruchs 1. The invention relates to a shaft flange of an agricultural harvesting machine according to the preamble of
Aus
In landwirtschaftlichen Erntemaschinen, wie zum Beispiel Feldhäckslern, kommen Wellenflansche zum Einsatz, die einerseits einen Flanschabschnitt zur Befestigung einer anzutreibenden Baugruppe der Erntemaschine und andererseits einen Wellenabschnitt zur Anbindung einer Riemenscheibe aufweisen. Der Wellenabschnitt des Wellenflansches, welcher der Anbindung einer Riemenscheibe dient, umfasst einen ersten Teilabschnitt, der mit mindestens einer Wellendichtung zusammenwirkt, einen zweiten Teilabschnitt, der mit einem Lager zusammenwirkt, und einen dritten Teilabschnitt, der mit einem Nabenabschnitt der Riemenscheibe zusammenwirkt. Der dritte Teilabschnitt, der mit dem Nabenabschnitt der Riemenscheibe zusammenwirkt, umfasst einen verzahnungsfreien Unterteilabschnitt und einen Unterteilabschnitt mit Verzahnung. In agricultural harvesters, such as forage harvesters, shaft flanges are used, which on the one hand have a flange portion for mounting a driven assembly of the harvester and on the other hand, a shaft portion for connecting a pulley. The shaft portion of the shaft flange, which serves to connect a pulley, comprises a first portion which cooperates with at least one shaft seal, a second portion which cooperates with a bearing, and a third portion which cooperates with a hub portion of the pulley. The third section, which cooperates with the hub section of the pulley, comprises a tooth-free lower section and a lower section with teeth.
Bei aus der Praxis bekannten Wellenflanschen sind die Wellenabschnitte derselben ausschließlich in dem Teilabschnitt des Wellenabschnitts, der mit der oder jeder Wellendichtung zusammenwirkt, oberflächenverfestigt. Da es sich bei derartigen Wellenflanschen um hochbelastete Baugruppen handelt, besteht die Gefahr, dass dieselben im Betrieb brechen und demnach versagen. Es besteht daher Bedarf an Wellenflanschen, die höher belastbar und demnach weniger bruchanfällig sind. In shaft flanges known in the art, the shaft portions thereof are surface-solidified only in the portion of the shaft portion cooperating with the or each shaft seal. Since such shaft flanges are highly loaded assemblies, there is a risk that they break during operation and therefore fail. There is therefore a need for shaft flanges, which are more resilient and therefore less prone to breakage.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen neuartigen Wellenflansch einer landwirtschaftlichen Erntemaschine zu schaffen, der weniger bruchanfällig ist. On this basis, the present invention seeks to provide a novel shaft flange of an agricultural harvester, which is less prone to breakage.
Diese Aufgabe wird durch einen Wellenflansch einer landwirtschaftlichen Erntemaschine nach Anspruch 1 gelöst. This object is achieved by a shaft flange of an agricultural harvesting machine according to
Erfindungsgemäß ist der Wellenabschnitt zumindest durchgehend in und durchgehend zwischen denjenigen Teilabschnitten sowie dem verzahnungsfreien Unterteilabschnitt des Teilabschnitts, die mit dem Lager und der oder jeder Wellendichtung und dem Nabenabschnitt der Riemenscheibe zusammenwirken, randschichtgehärtet ist. Hiermit kann die Bruchanfälligkeit eines Wellenflansches reduziert werden. According to the invention, the shaft section is at least continuous in and through between those sections and the non-toothed base portion of the subsection, which cooperate with the bearing and the or each shaft seal and the hub portion of the pulley, surface hardened. This can reduce the susceptibility to fracture of a shaft flange.
Vorzugsweise ist der Wellenabschnitt zumindest durchgehend in und durchgehend zwischen denjenigen Teilabschnitten, die mit dem Lager und der oder jeder Wellendichtung und dem Nabenabschnitt der Riemenscheibe zusammenwirken, randschichtgehärtet. Hiermit kann die Bruchanfälligkeit eines Wellenflansches weiter reduziert werden. Preferably, the shaft portion is surface hardened at least continuously in and through between those portions which cooperate with the bearing and the or each shaft seal and the hub portion of the pulley. Hereby, the susceptibility to fracture of a shaft flange can be further reduced.
Insbesondere ist der Wellenabschnitt ferner in einem Teilabschnitt, an welchem ein Klemmelement für den Nabenabschnitt angreift, und/oder in einem Übergangsbereich zum Flanschabschnitt randschichtgehärtet ist. Hiermit kann die Bruchanfälligkeit eines Wellenflansches weiter reduziert werden. In particular, the shaft portion is further in a partial section, on which a clamping element for the hub portion engages, and / or is surface hardened in a transition region to the flange portion. Hereby, the susceptibility to fracture of a shaft flange can be further reduced.
Besonders bevorzugt ist eine Ausführungsform, in welcher der Wellenabschnitt des Wellenflansches durchgehend zwischen dem Übergangsbereich zum Flanschabschnitt und einem dem Flanschabschnitt gegenüberliegenden Ende randschichtgehärtet ist. Ein derartiger Wellenflansch ist hochbelastbar und weniger bruchanfällig. Particularly preferred is an embodiment in which the shaft portion of the shaft flange is surface hardened continuously between the transition region to the flange portion and an opposite end of the flange portion. Such a shaft flange is heavy duty and less prone to breakage.
Nach einer vorteilhaften Weiterbildung der Erfindung weist der Wellenabschnitt im randschichtgehärteten Bereich an der Oberfläche eine Härte nach Rockwell zwischen 50 HRC und 60 HRC auf. Ausgehend von der Oberfläche nimmt die Härte des randschichtgehärteten Bereichs des Wellenabschnitts vorzugsweise derart ab, dass der Wellenabschnitt im randschichtgehärteten Bereich in einer Tiefe zwischen 10 mm und 14 mm von der Oberfläche eine Härte nach Rockwell von 40 HRC aufweist. Ein derartiger Wellenabschnitt weist im Bereich der Oberfläche eine Zugfestigkeit von mindestens 1800 N/mm2 bis zu 2200 N/mm2 auf. In der Tiefe zwischen 10 mm und 14 mm beträgt die Zugfestigkeit noch in etwa 1300 N/mm2. Ein derartiger Wellenflansch ist hochbelastbar. Die Bruchanfälligkeit desselben ist erheblich reduziert. According to an advantageous development of the invention, the shaft section in the surface-hardened area on the surface has a Rockwell hardness between 50 HRC and 60 HRC. Starting from the surface, the hardness of the surface hardened portion of the shaft portion preferably decreases such that the shaft portion in the surface hardened portion is at a depth of between 10 mm and 14 mm from the surface Surface has a Rockwell hardness of 40 HRC. Such a shaft section has a tensile strength of at least 1800 N / mm 2 up to 2200 N / mm 2 in the region of the surface. In the depth between 10 mm and 14 mm, the tensile strength is still in about 1300 N / mm 2 . Such a shaft flange is heavy duty. The susceptibility to breakage of the same is considerably reduced.

Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt: Preferred embodiments of the invention will become apparent from the dependent claims and the description below.
