Description
548505548505
Die Erfindung betrifft eine Treibkette, beispielsweise eine Motorradkette, deren Glieder abwechselnd aus zwei außenliegenden, durch Bolzen verbundenen Laschen und zwei innenliegenden, durch die Bolzen übergreifende Buchsen verbundenen Laschen bestehen. Die aus gehärtetem Stahl bestehenden und dauernd aufeinanderreibenden Bolzen und Buchsen unterliegen insbesondere bei hoher Laufgexo schwindigkeit hohem Verschleiß, der ein frühzeitiges Längen der Kette herbeiführt. Es ist daher schon vorgeschlagen worden, zwischen Buchse und Bolzen eine rohrförmige Hülse aus weicherem Material anzuordnen. Diese Hülsen sollten mit den Bolzen undrehbar verbunden sein. Hierdurch wird der Verschleiß zwar auf die Hülsen beschränkt, geht jedoch schnell vor sich, da der Druck stets von dem gleichen, räumlich begrenzten Hülsenteil aufgenommen wird.The invention relates to a drive chain, for example a motorcycle chain, its links alternating from two external brackets connected by bolts and two internal brackets there are tabs connected by the bolts overlapping sockets. Those made of hardened steel and permanent bolts and bushes rubbing against each other are subject to particularly high running gexo high speed of wear, which leads to the chain lengthening prematurely. It has therefore already been proposed to use a tubular shape between the bushing and the bolt To arrange sleeve made of softer material. These sleeves should be non-rotatable with the bolts be connected. This limits the wear and tear to the sleeves but quickly in front of you, since the pressure always comes from the same, spatially limited part of the sleeve is recorded.
Zur Vermeidung dieses Übelstandes sind die Hülsen erfindungsgemäß lose angeordnet. Die Hülsen können daher bei der Kettenbewegung auf den Bolzen in tangentialer Richtung wandern. Es findet somit ein steter Wechsel des unter Druck stehenden Hülsenteils statt, wodurch der Verschleiß verlangsamt wird.To avoid this inconvenience, the sleeves are loosely arranged according to the invention. The sleeves can therefore move on the bolts in the tangential direction during the chain movement hike. There is thus a constant change of the pressurized sleeve part instead, which slows down the wear and tear.
Die Lagerbuchse kann auch in der Achsrichtung geschlitzt oder in der Länge unterteilt und auch gelocht sein. Durch das Wandern der Hülse auf den Bolzen wird die Schmierung der Gelenke bedeutend verbessert. Auch die Unterteilung oder Schlitzung und Lochung der Hülse begünstigen den Durchtritt des Schmiermittels auf die Reibflächen. Die bewegliche Lagerhülse und die bessere Schmierung machen die Kette geschmeidiger und in den Gelenken biegsamer. Die Lebensdauer der Kette und der Wirkungsgrad des Motors werden erhöht.The bearing bush can also be slotted in the axial direction or divided in length and also be perforated. As the sleeve migrates on the bolt, the lubrication of the joints is significantly improved. The subdivision or slotting and perforation of the sleeve also promote the passage of the lubricant onto the friction surfaces. The movable bearing sleeve and the better lubrication make the chain smoother and more flexible in the joints. The service life of the chain and the efficiency of the motor are increased.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigen:The drawing shows an exemplary embodiment of the subject matter of the invention, namely show:
Fig. ι eine Seitenansicht undFig. Ι a side view and
Fig. 2 eine Draufsicht, zum Teil geschnitten. Fig. 2 is a plan view, partly in section.
Je zwei Gelenkbolzen α sind durch Vernietung mit den Enden je zweier außenliegenden Laschen d fest verbunden. Je zwei die Bolzen α übergreifende Buchsen b sind mit den Enden je zweier innenliegenden Laschen e verbunden. Zwischen den Bolzen a und den Buchsen b sind rohrförmige Hülsen c aus weicherem Stoff lose angeordnet, so daß sie in tangentialer Richtung wandern können. Diese Hülsen c können, wie in Fig. 1 angedeutet, in der Achsrichtung geschlitzt oder in der Länge unterteilt sein, wie in Fig. 2 rechts gestrichelt dargestellt ist. Die Hülsen c können auch gelocht sein. Auf den starr mit den innenliegenden Laschen e verbundenen Buchsen b sind bekannte rohrartige Rollen f lose angeordnet, die beim Eingriff der Ketten in die Zähne der Zahnräder sich auf den Buchsen b drehen können.Two hinge pins α are firmly connected by riveting to the ends of two outer straps d. In each case two bushings b overlapping the bolts α are connected to the ends of two inner straps e . Between the bolts a and the bushings b tubular sleeves c made of softer material are loosely arranged so that they can migrate in the tangential direction. These sleeves c can, as indicated in FIG. 1, be slotted in the axial direction or divided in length, as shown in broken lines on the right in FIG. 2. The sleeves c can also be perforated. B on the rigidly connected to the inner lugs e jacks known tubular rolls f loosely arranged, which can rotate on the b bushings upon engagement of the chain with the teeth of the gears.
