Description
Die Erfindung betrifft ein Verfahren gemäß den Merkmalen des Patentanspruchs 1.The invention relates to a method according to the features of
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 bearings are z. B. used in internal combustion engines for the storage of camshafts of the engine. It is necessary to supply the thrust bearing with lubricating oil. For this purpose, it is known to provide at least one chamfer in the engine block of the internal combustion engine, which ensures a lubricating oil supply of the thrust bearing. The preparation of such a chamfer is complex and therefore increases the production cost.
Beispielsweise beschreibt die Druckschrift
Der Erfindung liegt daher die Aufgabe zugrunde, ein einfaches Verfahren zur Herstellung einer Axiallagerschmiervorrichtung bereitzustellen, mit der Fertigungsaufwand reduziert werden kann.The invention is therefore based on the object to provide a simple method for producing a Axiallagerschmiervorrichtung, can be reduced with the manufacturing cost.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den Merkmalen des Hauptanspruchs. Vorteilhafte Ausgestaltungen der Erfindung beschreiben die Unteransprüche.The achievement of this task is the 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 handelt es sich um ein Axiallager, 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 the fact that in order to produce a thrust bearing lubrication device, before merging at least two housing sections, for example an upper and lower housing section of an engine block of an internal combustion engine, one of the housing sections is provided with a lubricating oil supply means. This is a thrust bearing, for example, for a camshaft of an internal combustion engine, which is arranged in the region of a parting line, wherein the parting line is arranged between the at least two housing sections.
Hierbei ist vorgesehen, dass ein rotierendes Werkzeug verwendet wird. Das rotierende Werkzeug wird 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.It is provided that a rotating tool is used. The rotary tool is fed only in the direction of its axis of rotation until the lubricating oil supply means is generated by contacting the processing surface. If this is done, the rotating tool is removed again only in the direction of its axis of rotation. As a result, a very simple production is possible because it can be dispensed with a transverse process of the rotating tool.
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.The rotating tool can be a form milling cutter, in particular a form milling cutter with a ball head, so that rotation-symmetrical machining takes place. However, other cutting tools may be used and other non-cutting machining methods may be used.
Es ist zudem 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. Erfindungsgemäß ist es jedoch vorgesehen, dass der Kanal einen kreissektorförmigen Querschnitt aufweist.It is also provided that a recess is formed, which forms a channel after merging the at least two housing sections, by the lubricating oil from a shaft receiving, z. B. for a camshaft, the thrust bearing can be supplied, wherein the rotation of the camshaft during operation causes a conveying action through the channel to the thrust bearing, so that an automatic and reliable supply of a thrust bearing is guaranteed with lubricating oil. The channel thus formed may have any cross-section. According to the invention, however, it is provided that the channel has a circular sector-shaped cross section.
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, it is preferably provided that the channel is arranged such that in the direction of rotation of the thrust bearing of the channel is arranged behind the parting line, so that despite the parting line reliable supply of the thrust bearing is ensured with lubricating oil. In this case, it is possible for the processing step to be provided with a lubricant oil supply means during the machining of a housing section, in which case a housing section, such as a housing section, may be provided. As the lower housing portion is provided with holes, grooves and / or depressions. Alternatively, the processing step may be provided with a lubricating oil supply means before or after the o. G. Machining a housing section done. In this case, it is generally not necessary to detach the housing section to be machined from a machining tool in order to provide it with the lubricating oil supply means by inserting a recess with a form milling cutter with a ball head. This simplifies the production and thus reduces the production costs.
