Abstract
Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a method according to the preamble of the claim 1.
Axiallager werden z.B. in Brennkraftmaschinen zur Lagerung von Nockenwellen der Brennkraftmaschine verwendet. Dabei ist es notwendig, das Axiallager mit Schmieröl zu versorgen. Hierzu ist es bekannt, im Motorblock der Brennkraftmaschine wenigstens eine Fase vorzusehen, die eine Schmierölversorgung des Axiallagers gewährleistet. Die Herstellung einer derartigen Fase ist aufwändig und erhöht daher den Fertigungsaufwand.thrust are used e.g. in internal combustion engines for the storage of camshafts the internal combustion engine used. It is necessary, the thrust bearing with lubricating oil to supply. For this purpose it is known in the engine block of the internal combustion engine to provide at least one chamfer providing a lubricating oil supply ensured the thrust bearing. The preparation of such a chamfer is complicated and therefore increases the production cost.
Der Erfindung liegt daher die Aufgabe zugrunde, ein einfaches Verfahren zur Herstellung einer Axiallagerschmiervorrichtung bereitzustellen, mit der Fertigungsaufwand reduziert werden kann.Of the The invention is therefore based on the object, a simple method to provide a thrust bearing lubrication device, can be reduced with the manufacturing cost.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs. Vorteilhafte Ausgestaltungen der Erfindung beschreiben die Unteransprüche.The inventive solution this Task is the characterizing features of the main claim. Advantageous embodiments of the invention describe the subclaims.
Die Erfindung beruht darauf, dass zur Herstellung einer Axiallagerschmiervorrichtung vor dem Zusammenführen von wenigstens zwei Gehäuseabschnitten, bspw. einem oberen und unteren Gehäuseabschnitt eines Motorblocks einer Brennkraftmaschine, einer der Gehäuseabschnitte mit einem Schmierölzuführungsmittel versehen wird. Dabei kann es sich insbesondere um ein Axiallager handeln, bspw. für eine Nockenwelle einer Brennkraftmaschine, dass im Bereich einer Trennfuge angeordnet ist, wobei die Trennfuge zwischen den wenigstens zwei Gehäuseabschnitten angeordnet ist.The Invention is based on that for producing a thrust bearing lubrication device before merging at least two housing sections, For example, an upper and lower housing portion of an engine block an internal combustion engine, one of the housing sections with a lubricating oil supply means is provided. This may in particular be a thrust bearing act, for example for a camshaft of an internal combustion engine that is in the range of Parting line is arranged, wherein the parting line between the at least two housing sections is arranged.
Hierbei ist bevorzugt vorgesehen, dass ein rotierendes Werkzeug verwendet wird. Bevorzugt wird das rotierende Werkzeug nur in Richtung seiner Drehachse zugeführt, bis durch Kontaktieren der Bearbeitungsfläche das Schmierölzuführungsmittel erzeugt wird. Ist dies erfolgt, so wird das rotierende Werkzeug nur in Richtung seiner Drehachse wieder abgeführt. Hierdurch ist eine sehr einfache Fertigung möglich, da auf ein Querverfahren des rotierenden Werkzeugs verzichtet werden kann.in this connection is preferably provided that uses a rotating tool becomes. Preferably, the rotating tool is only in the direction of its axis of rotation supplied until the working surface is contacted by the lubricating oil supply means is produced. If this is done, then the rotating tool discharged again only in the direction of its axis of rotation. This is a very simple production possible, because there is no need for a transverse process of the rotating tool can.
Bei dem rotierenden Werkzeug kann es sich um einen Formfräser handeln, insbesondere einen Formfräser mit einem Kugelkopf, so dass eine rotationssymmetrische Bearbeitung erfolgt. Jedoch können auch andere, spanabhebende Werkzeuge Verwendung finden und anderen, spanlose Bearbeitungsverfahren zur Anwendung kommen.at the rotating tool may be a form cutter, in particular a form cutter with a ball head, allowing rotationally symmetric machining he follows. However, you can using other, cutting tools and others, non-cutting machining methods are used.
Dabei ist bevorzugt vorgesehen, dass eine Vertiefung gebildet wird, die nach Zusammenführen der wenigstens zwei Gehäuseabschnitte einen Kanal bildet, durch den Schmieröl aus einer Wellenaufnahme, z.B. für eine Nockenwelle, dem Axiallager zugeführt werden kann, wobei die Drehung der Nockenwellen während des Betriebs eine Förderwirkung durch den Kanal zum Axiallager bewirkt, sodass eine selbsttätige und zuverlässige Versorgung eines Axiallagers mit Schmieröl gewährleistet ist. Der so gebildete Kanal kann einen beliebigen Querschnitt aufweisen. Es ist jedoch bevorzugt vorgesehen, dass der Kanal einen kreissektorförmigen Querschnitt aufweist.there is preferably provided that a depression is formed, the after merging the at least two housing sections forming a channel through the lubricating oil from a shaft receiving, e.g. For a camshaft, the thrust bearing can be supplied, wherein the Rotation of the camshafts during a promotion effect of the operation causes the channel to the thrust bearing, so that an automatic and reliable Supply of a thrust bearing is guaranteed with lubricating oil. The thus formed Channel can have any cross section. However, it is preferably provided that the channel has a circular sector-shaped cross-section having.
Ferner ist bevorzugt vorgesehen, dass der Kanal derart angeordnet wird, dass in Drehrichtung des Axiallagers der Kanal hinter der Trennfuge angeordnet ist, sodass trotz der Trennfuge eine zuverlässige Versorgung des Axiallagers mit Schmieröl gewährleistet ist. Es kann dabei bevorzugt der Bearbeitungsschritt Versehen mit einem Schmierölzuführungsmittel während der Bearbeitung eines Gehäuseabschnitts erfolgen, bei dem ein Gehäuseabschnitt, wie z.B. der untere Gehäuseabschnitt, mit Bohrungen, Nuten und/oder Vertiefungen versehen wird. Alternativ hierzu kann der Bearbeitungsschritt Versehen mit einem Schmierölzuführungsmittel vor oder nach der o.g. Bearbeitung eines Gehäuseabschnitts erfolgen. Dabei ist es allgemein nicht erforderlich, den zu bearbeitenden Gehäuseabschnitt aus einem Bearbeitungswerkzeug zu lösen, um ihn mit dem Schmierölzuführungsmittel durch Einbringen einer Vertiefung mit einem Formfräser mit einem Kugelkopf zu versehen. Dies vereinfacht die Herstellung und reduziert damit den Fertigungsaufwand.Further is preferably provided that the channel is arranged such that in the direction of rotation of the thrust bearing of the channel behind the parting line is arranged so that, despite the parting line, a reliable supply of the thrust bearing with lubricating oil guaranteed is. In this case, it is possible to provide the processing step with a lubricating oil supply means while the machining of a housing section take place, in which a housing section, such as. the lower housing section, is provided with holes, grooves and / or depressions. alternative For this, the processing step may be provided with a lubricating oil supply means before or after the o.g. Machining a housing section done. there it is generally not necessary to edit the housing section from a machining tool to release it with the lubricating oil supply means by introducing a depression with a form cutter with to provide a ball head. This simplifies the production and thus reduces the production costs.
