Description
Riemenrücker. Der Gegenstand der Erfindung ist eine Vorrichtung zum Ein- und Ausrücken von Riementrieben, welche von dem bei den bekannten Vorrichtungen zu gleichem Zwecke vielfach zu beobachtenden Fehler des unbeabsichtigten selbsttätigen Ausrückens frei ist. Die Erfindung besteht darin, daß der in der Achsenrichtung der angetriebenen Welle verschiebbare Träger der Riemengabel mit einer seine Verschiebung- bewirkenden, fest gelagerten Welle durch ein Gelenkviereck derart verbunden ist,' daß zwei Gelenkstangen in der vorgeschobenen Lage des Rückers eine gestreckte und zum Gabelträger parallele Lage einnehmen.Strap pusher. The object of the invention is a device for Engagement and disengagement of belt drives, which of the known devices for the same purpose often observed errors of the unintentional automatic Disengagement is free. The invention consists in that in the axial direction the driven shaft displaceable carrier of the belt fork with its displacement effecting, fixed shaft is connected by a four-bar linkage in such a way, ' that two articulated rods in the advanced position of the Rückers one stretched and assume a position parallel to the fork carriage.
Die Zeichnung stellt den Erfindungsgegenstand in einem Ausführungsbeispiele dar: Der mit der Losscheibe a und der Festscheibe b, welche auf der Welle c angeordnet sind, zusammenarbeitende Riemen d wird durch die auf der. Stange t sitzende Gabel f verschoben, Die Stange e, welche in den Führungen g und h verschiebbar ist, wird von der an der Führung g gelagerten, mittels des stangenförmigen -Hebels k gedrehten Welle r aus verstellt. Auf der Welle r sitzt der Hebel i, dessen eines Ende" welches einen Zapfen P trägt, mit dem Zapfen l an der Stange e durch die Doppelschubstange m verbunden ist. Ferner greift an dem Zapfen l die etwas nach außen gekröpfte Schubstange n an, welche mit dem Zapfen .q am anderen Ende des Hebels i durch die Doppelgelenkstange ö verbunden ist.The drawing shows the subject matter of the invention in an exemplary embodiment: The belt d, which cooperates with the loose pulley a and the fixed pulley b, which are arranged on the shaft c, is supported by the belt d on the. Rod t seated fork f displaced, the rod e, which is displaceable in the guides g and h, is adjusted by the shaft r, which is mounted on the guide g and rotated by means of the rod-shaped lever k. The lever i sits on the shaft r, one end of which "carries a pin P, is connected to the pin l on the rod e through the double push rod m. Furthermore, the push rod n, which is cranked slightly outward, engages the pin l is connected to the pin .q at the other end of the lever i by the double joint rod ö.
Befinden sich die Teile i, in, n und o in der in Fig. z durch vollausgezogene Linien wieder 35 gegebenen Stellung, so ist der Riemen eingerückt. Die Teile i und- m nehmen dabei in bezug aufeinander eine solche Lage ein, daß die Achsen der Zapfen l und p mit der Drehachse des Hebels i in einer Ebene liegen, oder 40 besser noch; daß die Achse des Zapfens p über die durch die Drehachse des Hebels i und die Achse des Zapfens l bestimmte Ebene in der Richtung, in welcher der Hebel i beim -Einrücken des Riemens gedreht wird, etwas 45 hervorsteht, so daß ein unbeabsichtigtes Ausrücken des Riemens nicht stattfinden kann.If the parts i, in, n and o are in the position shown again by solid lines in FIG. Z, the belt is engaged. The parts i and m assume such a position with respect to one another that the axes of the pins l and p lie in one plane with the axis of rotation of the lever i, or better still; that the axis of the pin p over the plane determined by the axis of rotation of the lever i and the axis of the pin l in the direction in which the lever i is rotated when engaging the belt, protrudes somewhat 45, so that an unintentional disengagement of the belt cannot take place.
Die in Fig. r strichpunktiert gezeichnete Stellung wird von- den Teilen i, m, n und o eingenommen, wenn der Riemen ausgerückt 5o ist. Beim Übergang aus der einen Endlage in die andere wird die Stange e nicht einseitig beansprucht, so daß Kleznmungen nicht zu befürchten sind.The position shown in phantom in FIG. R is assumed by parts i, m, n and o when the belt is disengaged. During the transition from one end position to the other, the rod e is not stressed on one side, so that sticking is not to be feared.
