Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Gleitelement für einen Kettentrieb gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a sliding element for a chain drive according to the preamble of the claim 1.
Gleitelemente, wie Gleitschienen, werden in schnell laufenden Kettentrieben verwendet, um die Kette zu führen, d. h. Transversalschwingungen klein zu halten, und dieselbe zu spannen. Typische Ausführungen sind aus Vollkunststoff oder aus Metallträgern mit aufgebrachten Kunststoffschienen aus Polyamid hergestellt. Die zusammenwirkenden Oberflächen der Kette und der Gleitschiene sind im Betrieb beölt und erreichen eine hohe Verschleißfestigkeit.Sliding elements, like slide rails, are used in high-speed chain drives, to lead the chain, d. H. Transverse oscillations small to hold, and to tension the same. Typical designs are made of solid plastic or metal carriers with applied Plastic rails made of polyamide. The cooperative The surfaces of the chain and the slide rail are oiled during operation and achieve high wear resistance.
Die konvexe Außenkontur von Gleitschienen ist typischerweise am Anfang und Ende der Gleitschienen stärker gekrümmt als in der Mitte, um ein sanftes und definiertes Anschmiegen und Abheben der Kette zu sichern. Diese Außenkontur lässt sich beispielsweise aus drei Kreisbogenstücken zusammensetzen, die an ihren Übergängen stetig differenzierbar verbunden sind.The Convex outer contour of slide rails is typically more curved at the beginning and end of the slide rails as in the middle, to a gentle and defined nestling and Take off the chain. This outer contour leaves for example, consist of three circular arc pieces, which are constantly differentiable at their transitions are connected.
Die
gattungsbildende
Ein Nachteil dieser bekannten Gleitschiene besteht darin, dass diese relativ aufwendig herzustellen ist, da die Anzahl der aneinander zu befestigenden Einzelteile hoch ist.One Disadvantage of this known slide is that this is relatively expensive to produce, since the number of each other is high to be fixed items.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Gleitelement für einen Kettentrieb zu schaffen, dessen Herstellungsaufwand und Reibung reduziert sind.Of the Invention is based on the object, a generic To provide sliding element for a chain drive, whose Manufacturing costs and friction are reduced.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausgestaltungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the characterizing features of the main claim, advantageous Embodiments of the invention describe the subclaims.
Ein Vorteil der vorliegenden Erfindung besteht darin, dass das erfindungsgemäße Gleitelement aus einem Stück und nicht aus mehreren Stücken gebildet ist, die beispielsweise über Träger aufwendig zu verbinden sind. Dadurch wird ein Gleitelement geschaffen, das mit einem geringen Aufwand hergestellt werden kann.One Advantage of the present invention is that the inventive Sliding element in one piece and not in several pieces is formed, consuming, for example, about carrier to connect. Thereby, a sliding element is created, the can be produced with a low cost.
Ein weiterer Vorteil der vorliegenden Erfindung besteht darin, dass reibungsreduzierende vertiefte Abschnitte ohne Weiteres in beliebiger Zahl, Abmessung und Anordnung in dem Gleitelement gebildet sein können. Dadurch wird ein reibungsreduziertes, flexibel gestaltbares Gleitelement mit guten Führungseigenschaften geschaffen.One Another advantage of the present invention is that friction reducing recessed sections readily in any Number, size and arrangement may be formed in the sliding member can. This will be a friction-reduced, flexible shapable sliding element with good guiding properties created.
Bevorzugte Ausführungsbeispiele der vorliegenden Erfindung sind nachfolgend unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert. Es zeigen:preferred Embodiments of the present invention are as follows with reference to the accompanying drawings explained. Show it:

Die Schienenreibung ist der dominante Anteil bei einem Großteil der Kettentriebe mit Gleitschienen. Abhängig von den geometrischen Voraussetzungen wird abgeschätzt, dass sich dieser Reibungsanteil mit dem erfindungsgemäßen Gleitelement um bis zu 50% reduzieren lässt.The Rail friction is the dominant part of a large part the chain drive with slide rails. Depending on the geometric Prerequisites are estimated that this friction component with the sliding element according to the invention by up 50% reduction.
Obwohl die vorliegende Erfindung vorstehend anhand bevorzugter Ausführungsbeispiele beschrieben ist, ist dieselbe darauf nicht beschränkt, sondern auf vielfältige Art und Weise modifizierbar.Although the present invention prevailed Hend is described with reference to preferred embodiments, the same is not limited thereto, but modifiable in a variety of ways.
