Abstract
Description
Die Erfindung betrifft ein Kettenglied für eine in einem Kettenantrieb zusammen mit einer Spannschiene zu verwendenden Kette.The invention relates to a chain link for a chain drive to be used together with a tensioning rail chain.
Aus der Praxis sind Ketten bekannt, die als Rollen- oder Hülsenkette ausgebildet sind, wobei solche Ketten zusammen mit einer Spannschiene insbesondere in Steuerkettentrieben Verwendung finden. Zwischen der Kette und der Spannschiene entsteht im Betrieb eine nicht zu vernachlässigende Reibung, die sowohl zu einem Verschleiß der Spannschiene führt als auch Reibungsverluste zur Folge hat.From practice chains are known, which are designed as a roller or sleeve chain, such chains are used together with a clamping rail in particular in timing chain drives. In operation, a not insignificant friction arises between the chain and the tensioning rail, which leads both to wear of the tensioning rail and also to friction losses.
Der Erfindung liegt die Aufgabe zugrunde, ein reibungsarmes Kettenglied zur Verfügung zu stellen, um insbesondere bei Motoren Reibungsverlustvorteile zu erzielen.The object of the invention is to provide a low-friction chain link in order to achieve friction loss advantages, in particular in engines.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Anspruchs 1.The solution of this object is achieved according to the invention with the features of
Gemäß der Erfindung ist bei einem Kettenglied mit mindestens einer ersten und einer zweiten Lasche, insbesondere Innenlasche, sowie mit mindestens einem ersten und einem zweiten Bolzen, über welche die Innenlaschen unter Ausbildung eines Zwischenabstands miteinander verbunden sind, vorgesehen, dass zwischen den Innenaschen zumindest ein Zwischenteil angeordnet ist, welches wenigstens eine Surf-Fläche aufweist, mittels welcher das Kettenglied bei einem Gleiten des Kettengliedes über eine Spannschiene durch ein Schmiermittel hydrodynamisch an der Spannschiene abstützbar ist Durch eine solche hydrodynamische Abstützung wird ein direkter Reibkontakt zwischen dem Kettenglied und der Spannschiene vermieden, wodurch Reibungsverluste und Verschleiß vermindert werden.According to the invention, in a chain link with at least one first and one second lug, in particular inner lug, as well as with at least one first and one second bolt via which the inner lugs are connected to form a spacing, it is provided that between the inner lugs at least one intermediate part is arranged, which has at least one surf surface, by means of which the chain member hydrodynamically supported on a sliding of the chain link via a clamping rail by a lubricant on the clamping rail by such a hydrodynamic support direct frictional contact between the chain link and the clamping rail is avoided, thereby Friction losses and wear are reduced.
Gemäß einer bevorzugten Ausgestaltung der Erfindung weist das Kettenglied wenigstens bereichsweise einen zumindest im Wesentlichen wannenförmigen Querschnitt auf, wobei die Wannenform auch zumindest im Wesentlichen als U-Form angesehen werden kann und durch die Innenlaschen sowie das Zwischenteil gebildet ist. Dadurch wird Schmiermittel in den Bereich transportiert, in dem die Abstützung zwischen dem Kettenglied und der Spannschiene erfolgt.According to a preferred embodiment of the invention, the chain link at least partially an at least substantially trough-shaped cross-section, wherein the trough shape can also be considered at least substantially U-shape and is formed by the inner plates and the intermediate part. As a result, lubricant is transported to the area in which the support between the chain link and the clamping rail takes place.
Die Surffläche ist dabei beispielsweise an einer in Zugrichtung des Kettengliedes und/oder entgegen der Zugrichtung weisenden Wandung des Zwischenteils vorgesehen, was die hydrodynamische Abstützung des Kettengliedes an der Spannschiene und somit eine weitere Reduzierung der Reibungsverluste und des Verschleißes begünstigt.The surf surface is provided, for example, on a wall of the intermediate part pointing in the pulling direction of the chain link and / or against the pulling direction, which favors the hydrodynamic support of the chain link on the tensioning rail and thus a further reduction of the friction losses and wear.
In jeglicher Hinsicht schwimmt das Kettenglied durch die Surf-Fläche auf dem Schmiermittel besonders gut auf und reibt somit nicht mehr direkt an der Spannschiene, was eine besonders niedrige Reibung bedeutet.In all respects, the chain link floats particularly well through the surf surface on the lubricant and thus does not rub directly on the tension rail, which means a particularly low friction.
Um dieses Aufschwimmen weiter zu verbessern ist bei einer weiteren vorteilhaften Ausführungsform vorgesehen, dass die Surf-Fläche zumindest bereichsweise zu der Zugrichtung des Kettengliedes geneigt ist und beispielsweise in Zugrichtung des Kettengliedes, also zu einer Außenseite der Innenlasche hin, ansteigend ausgebildet ist. Dies begünstigt ein Strömen des Schmiermittels zwischen das Kettenglied bzw. das Zwischenteil und die Spannschiene, was der niedrigen Reibung sowie dem niedrigen Verschleiß weiterhin zugute kommt.To further improve this floating is provided in a further advantageous embodiment, that the surf surface is at least partially inclined to the pulling direction of the chain link and, for example, in the pulling direction of the chain link, ie to an outer side of the inner plate out, is formed increasing. This promotes a flow of lubricant between the chain link or the intermediate part and the clamping rail, which continues to benefit the low friction and the low wear.
Ebenso kann vorgesehen sein, dass die Surf-Fläche zumindest bereichsweise gekrümmt, insbesondere im Wesentlichen bogenförmig, ausgebildet ist. Dabei weist das Zwischenteil beispielsweise zumindest bereichsweise einen wannenförmigen Längsschnitt auf, der die hydrodynamische Abstützung des Kettengliedes an der Spannschiene positiv beeinflusst.Likewise it can be provided that the surf surface is at least partially curved, in particular substantially arcuate, is formed. In this case, the intermediate part, for example, at least partially a trough-shaped longitudinal section, which positively influences the hydrodynamic support of the chain link on the clamping rail.
