Description
Die vorliegende Erfindung betrifft eine elastische Kupplungsplatte für ein Universalgelenk von der Art, in welcher jede Büchse für die Verbindungsbolzen für die Bügel des Universalgelenks mit den anliegenden beiden Büchsen durch eine biegsame, in die Platte eingebettete Seilschleife verbunden ist, und jede Seilschleife gegen sich selbst derart verdreht ist, dass sie in Draufsicht die Form einer Acht bildet.The present invention relates to a flexible coupling plate for a universal joint of the type in which each bush for the connecting bolts for the brackets of the universal joint is connected to the adjacent two bushes by a flexible rope loop embedded in the plate, and each rope loop against itself in this way is twisted so that it forms the shape of a figure eight in plan view.
Es ist bereits eine Anordnung dieser Art bekannt, in welcher die Seilschleifen aus unverdrillten, mit Gewebeeinlagen versehenen Gummibändern bestehen (U.S.A.-Patentschrift 1 424 051).An arrangement of this type is already known in which the rope loops consist of untwisted rubber bands provided with fabric inserts (U.S. Patent 1,424,051).
Der Erfindung liegt die Aufgabe zugrunde, eine derartige Kupplungsplatte so auszubilden, dass sie im Vergleich zu bekannten Kupplungsplatten eine niedrige Steifheit gegenüber Schwenkbewegungen aufweist, aber eine hohe Steifheit gegen Drehbewegungen. Dies wird erfindungsgemäß dadurch erreicht, dass die Kupplungsplatte in Draufsicht die Form einer Acht bildet, dass jede achterförmige Seilschleife aus einem spiralförmig verdrillten Strang besteht, der einen endlosen Ring bildet, welcher in die Achterform in eine Richtung verdreht wird, die der augenblicklichen Verdrehungsbewegung unter Einfluss eines diametral ausgeübten Drucks entspricht.The invention is based on the object of designing such a coupling plate in such a way that, compared to known coupling plates, it has a low rigidity with respect to pivoting movements, but high rigidity with respect to rotary movements. This is achieved according to the invention in that the coupling plate forms the shape of a figure eight in plan view, that each figure eight-shaped rope loop consists of a helically twisted strand that forms an endless ring which is twisted into the figure of eight in a direction that is influenced by the current twisting movement corresponds to a diametrically applied pressure.
Weitere Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus der anliegenden Beschreibung in Verbindung mit den beiliegenden Zeichnungen, die ein Ausführungsbeispiel darstellen. Es zeigen:Further features and advantages of the present invention emerge from the attached description in conjunction with the accompanying drawings, which illustrate an exemplary embodiment. Show it:
Figur 1 einen axialen Schnitt durch ein Universalgelenk, das mit einer erfindungsgemäßen Kupplungsplatte ausgestattet ist,Figure 1 is an axial section through a universal joint which is equipped with a coupling plate according to the invention,
Figur 2 eine Draufsicht auf die in der Anordnung der Figur 1 verwendete Kupplungsplatte,Figure 2 is a plan view of the coupling plate used in the arrangement of Figure 1,
Figur 3 einen Querschnitt längs der Linie III-III der Figur 2,Figure 3 shows a cross section along the line III-III of Figure 2,
Figuren 4 bis 6 eine metallische Seilschleife in drei aufeinanderfolgenden Herstellungsstufen,Figures 4 to 6 show a metallic rope loop in three successive manufacturing stages,
Figur 7 eine vergrößerte Teilansicht der metallischen Seilschleife.FIG. 7 is an enlarged partial view of the metallic rope loop.
Die Bezugszeichen 12 und 13 kennzeichnen jeweils eine treibende und getriebene Welle, wovon jede einen Bügel 1, 2 trägt, der mit zwei Armen versehen ist.The reference numerals 12 and 13 each denote a driving and driven shaft, each of which carries a bracket 1, 2 which is provided with two arms.
Die Arme des Bügels 1 sind im rechten Winkel zu den Armen des Bügels 2 angeordnet und jeder Arm weist eine axial verlaufende Öffnung zur Aufnahme eines Bolzens 3 beziehungsweise 4 auf, durch welchen der Arm mit einer zwischen den Bügeln angeordneten elastischen Kupplungsplatte 6 verbunden wird.The arms of the bracket 1 are arranged at right angles to the arms of the bracket 2 and each arm has an axially extending opening for receiving a bolt 3 or 4, through which the arm is connected to an elastic coupling plate 6 arranged between the brackets.
Der gegenseitige Abstand der Öffnungen in den Armen der Bügel 1 entspricht dem gegenseitigen Abstand der Öffnungen in den Armen des Bügels 2.The mutual spacing of the openings in the arms of the bracket 1 corresponds to the mutual spacing of the openings in the arms of the bracket 2.
Die elastische Kupplungsplatte besteht aus einem vulkanisiertenThe elastic coupling plate consists of a vulcanized
Gummikörper, der vier Öffnungen 7 aufweist, die in gleichmäßigem Abstand auf einem gemeinsamen Umfang angeordnet sind, dessen Durchmesser dem gegenseitigen Abstand der Öffnungen in den Bügeln entspricht.Rubber body, which has four openings 7, which are evenly spaced on a common circumference, the diameter of which corresponds to the mutual spacing of the openings in the bracket.
In jede der Öffnungen 7 in der Platte 6 ist eine zylindrische metallische Büchse 8 für den Verbindungsbolzen mit einem leichten Reibungssitz angeordnet. Zwei Metallflansche 9 sind an jedem Ende der zylindrischen Büchse 8 verkeilt und pressen zwischen sich den anliegenden Abschnitt der Platte 6 zusammen.In each of the openings 7 in the plate 6 a cylindrical metallic sleeve 8 for the connecting bolt is arranged with a slight friction fit. Two metal flanges 9 are wedged at each end of the cylindrical sleeve 8 and press the adjacent portion of the plate 6 together between them.
Auf diese Weise sind die Büchsen gleichmäßig an dem vorausgehend genannten Umfang angeordnet.In this way the sleeves are arranged uniformly on the aforementioned circumference.
Vier metallische Seilschleifen 5 sind in die Platte 6 eingebettet und jede Schleife umgibt zwei aufeinanderfolgende Büchsen 8, wobei jede Büchse in der Platte durch ein Paar von Schleifen mit der anliegenden Büchse verbunden wird (das heißt der vorangehenden und der folgenden Büchse).Four metallic rope loops 5 are embedded in the plate 6 and each loop surrounds two successive sleeves 8, each sleeve in the plate being connected to the adjacent sleeve (i.e. the preceding and following sleeve) by a pair of loops.
Jede Schleife 5 ist um eine halbe Windung gegen sich selbst verdrillt, um in Draufsicht die Form einer Acht zu bilden (Figur 6).Each loop 5 is twisted against itself by half a turn in order to form a figure of eight in plan view (FIG. 6).
Die Achterschleife 5 wird erhalten, indem man ein Einzelbündel 10 von Metalldrähten in einen kreisförmigen Ring 5a (Figur 4) verdrillt und diesen Ring gemäß Figur 5 in diametraler Richtung zusammendrückt. Dabei nimmt der Ring eine in Figur 5 dargestellte Zwischenlage 5b an und verdrillt sich augenblicklich gegen sich selbst in die in Figur 6 gezeigte Endform.The figure-of-eight loop 5 is obtained by twisting a single bundle 10 of metal wires into a circular ring 5a (FIG. 4) and compressing this ring according to FIG. 5 in the diametrical direction. The ring assumes an intermediate layer 5b shown in FIG. 5 and instantly twists against itself into the final shape shown in FIG.
Infolge der Achterform der Schleifen 5 können am Umfang der Platte 6 Ausnehmungen 11 angeordnet werden, wovon jede Ausnehmung zwischen zwei aufeinanderfolgenden Büchsen liegt und längs einer Seite der jeweiligen Schleife 5, wie aus Figur 2 ersichtlich ist.As a result of the figure-eight shape of the loops 5, recesses 11 can be arranged on the circumference of the plate 6, each recess lying between two successive sleeves and along one side of the respective loop 5, as can be seen from FIG.
Versuche haben ergeben, dass die erfindungsgemäßen Kupplungsplatten in Verbindung mit Universalgelenken gegenüber bekannten Anordnungen eindeutig überlegene Eigenschaften aufweisen, und zwar besonders wenn eine Kraftübertragung zwischen Wellen erfolgt, die in einem merklichen Winkel zueinander angeordnet sind.Tests have shown that the coupling plates according to the invention in connection with universal joints have clearly superior properties compared to known arrangements, in particular when power is transmitted between shafts which are arranged at a noticeable angle to one another.
