Abstract
Gleitender Reibung ausgesetztes, aus einer metallischen Legierung bestehendes Bauteil, das im Bereich seiner Gleitfläche mit einer Vielzahl von zur Einlagerung von Schmiermittel dienenden, punktuellen Vertiefungen versehen ist.Sliding friction exposed, consisting of a metallic alloy component, which is provided in the region of its sliding surface with a plurality of serving for the storage of lubricant, punctiform depressions.
Description
Die Erfindung betrifft ein gleitender Reibung ausgesetztes Bauteil.The The invention relates to a sliding friction exposed component.
In
der
Gleitender Reibung ausgesetzte Bauteile sind extrem eben und glatt ausgebildet, so dass sich ein Schmierfilm zwischen den Gleitpartnern nur sehr schwer bilden kann. Hier kann es jedoch gerade beim ersten Anlauf der derartige Bauteile beinhaltenden Einrichtung hin und wieder zu zerstörendem Reibverschleiß kommen.Moving Friction exposed components are extremely flat and smooth, so that a lubricating film between the sliding partners only very difficult to form. However, it may be here at the first attempt the device containing such components now and then come to destructive fretting.
Ziel des Erfindungsgegenstandes ist es, ein gleitender Reibung ausgesetztes Bauteil aus einer speziellen Legierung bereit zu stellen, bei welchem sich insbesondere für den ersten Anlaufvorgang der das Bauteil beinhaltenden Einrichtung entweder ein Ölfilm aufbauen kann oder bereits gegeben ist, so dass die Standzeit des gleitender Reibung ausgesetzten Bauteils gegenüber dem Stand der Technik erhöht ist.aim of the subject invention is exposed to a sliding friction To provide a component made of a special alloy, in which especially for the first startup of the Component-containing device either build an oil film may or already exists, so that the life of the sliding Friction exposed component over the prior art is increased.
Dieses Ziel wird erreicht durch ein gleitender Reibung ausgesetztes aus einer metallischen Legierung bestehendes Bauteil, das im Bereich seiner Gleitfläche mit einer Vielzahl von, zur Einlagerung von Schmiermittel dienenden, punktuellen Vertiefungen versehen ist.This Target is reached by a sliding friction exposed out a metallic alloy component in the field its sliding surface with a variety of, for storage provided by lubricants, punctiform depressions.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.advantageous Further developments of the subject invention are the dependent claims refer to.
Die zum Einsatz gelangenden Vertiefungen sind bevorzugt durch Mikroöltaschen, wie etwa kugelsegmentartig ausgebildete Vertiefungen oder dergleichen, gebildet.The used depressions are preferred by micro oil pockets, such as spherical segment depressions or the like, educated.
Das zum Einsatz gelangende Bauteil kann, einem weiteren Gedanken der Erfindung gemäß, einen scheibenförmigen Grundkörper mit planer Gleitfläche beinhalten, insbesondere durch eine in einem Hydraulikaggregat einsetzbare Verteilerplatte gebildet sein, wobei der Grundkörper unter anderem mit Öldurchlasskanälen versehen ist und die Vertiefungen im jeweiligen radialen Bereich des jeweiligen Öldurchlasskanals angeordnet sind.The used component can, another idea of the Invention according to a disc-shaped Contain base body with a flat sliding surface, in particular by a distributor plate which can be used in a hydraulic unit be formed, wherein the body including with oil passage channels is provided and the wells in the respective radial region the respective oil passage channel are arranged.
Je nach Ausgestaltung des mit Öldurchlasskanälen versehenen Grundkörpers können die Vertiefungen entweder nur den jeweiligen Öldurchlasskanal umgeben, nur zwischen einzelnen Öldurchlasskanälen vorgesehen sein oder aber im Gleitflächenbereich die Öldurchlasskanäle überdeckend angeordnet werden.ever after embodiment of the oil passage channels provided basic body, the wells either surrounded only the respective oil passage, only provided between individual oil passageways be or in the Gleitflächenbereich the oil passages covering to be ordered.
Diese Vertiefungen, die beispielsweise durch Prägen oder ähnliche Bearbeitung mit einem Werkzeug in die entsprechenden Gleitflächenbereiche des Grundkörpers eingebracht werden können, dienen dazu, bereits bei der Montage der das gleitender Reibung ausgesetzte Bauteil aufnehmenden Einrichtung minimale Mengen an Öl zu speichern. Dieses Öl verhindert während der Anlaufphase den eingangs angedeuteten unerwünschten Reibverschleiß.These Depressions, for example, by embossing or similar Machining with a tool in the corresponding Gleitflächenbereiche of the main body can be introduced serve to, already at the assembly of the sliding friction exposed Component receiving device minimum amounts of oil save. This oil prevents during the Start-up phase the initially indicated unwanted fretting.
