Description
Riemscheibengetriebe mit verschieden großen Scheiben. Die Erfindung betrifft ein Riem kheibengetriebe mit verschieden großen Scheiben, bei welchem die kleinere Scheibe schwingend angeordnet und zur Vergrößerung ihres Urnschlingun;gswitnkels eine Leitrolle vorgesehen ist.Pulley drive with different sized pulleys. The invention relates to a belt drive with pulleys of different sizes, in which the smaller disc arranged swinging and to enlarge its looping; gswitnkels a guide roller is provided.
Riemscheibengetriebe mit verschieden großen Scheiben, bei welchen die kleinere Scheibe schwingend gelagert ist, sind, an sich bekannt und werden z. B. bei Webstühlen mit elektrischem Einzelantrieb häufig benutzt. Diese bekannten Getriebe erfordern jethoch einen verhältnismäßig großen. Achsenabstand zwischen den beiden Scheiben und können dann nicht Anwendung finden, wenn das Verhältnis des Durchmessers der größeren Scheibe zum, Durchmesser der kleineren Scheibe größer ist als 5 : i. Bei kleinem Achsenabstand und großem Übersetzungsverhältnis wird dann der Umschlingungswinkel an der - schwingenden Scheibe so klein, daß die Kraftübertragung nur durch entsprechend stärkere Riemenspannung stattfinden kann, wodurch Kraftverlust, Ölverbrauch und die Gefahr des Warmlaufens erheblich vermehrt werden.Pulley drive with different sized pulleys, with which the smaller disc is mounted oscillating, are known per se and are z. B. often used in looms with electric single drive. These well-known Gearboxes require a relatively large one. Axis distance between the two disks and then can not apply if the ratio the diameter of the larger disk to, the diameter of the smaller disk larger is as 5: i. With a small center distance and a large transmission ratio, then the wrap angle on the - vibrating disk so small that the power transmission can only take place through a correspondingly stronger belt tension, which leads to a loss of power, Oil consumption and the risk of warming up are considerably increased.
Diese Nachteile werden gemäß der Erfin- Jung dadurch vermieden, däß zur Vergrößerung des Umschlingungswinkels an der kleineren schwingenden Scheibe zugleich eine Leitrolle vorg-esehen ist.These disadvantages are according to the invention Young by that avoided that to increase the wrap angle on the smaller vibrating Disc is also provided as a guide roller.
Die Verwendung von Leitrollen bei Riemscheibengetrieben ist ebenfalls an sich bekannt. Die Erfindung wird lediglich in der Anwendung einer solchen Leitrolle bei Riemscheibengetrieben mit verschieden großen Scheiben, bei welchen die kleinere Scheibe schwingend gelagert ist. erblickt, da dadurch die vorstehend gekennzeichneten Nachteile vermieden und das Anwendungsgebiet derartiger Riemscheibengetriebe vergrößert wird,.The use of idler pulleys in pulley drives is also known per se. The invention is only in the application of such a guide roller in the case of pulley drives with different sized pulleys, in which the smaller one Disc is mounted swinging. behold, as this means the above-identified Avoid disadvantages and increase the field of application of such pulley drives will,.
Auf der 7eichnung sind in den Abb. i bis 3 verschiedene Ausführungsformen des neuen Riemscheibengetriebes schematisch dargestellt.On the 7eichnung are in Figs. 1 to 3 different embodiments of the new pulley drive shown schematically.
Bei allen drei Ausführungsformen wird der die beiden Scheiben verbindende Riemen. über eine Leitrolle i geführt, die so angeordnet ist, daß die kleinere Scheibe 2 etwa zur Hälfte vom Riemen erfa$'t wird. Die Leitrolle i kann entweder, wie in Abb. i gezeigt, auf einem besonderen Bolzen 3 laufen oder, wie Abb.2 und 3 zeigen, auf einer Achse d. angeordnet sein, um welche die kleinere Scheibe 2 schwingt. Während bei den Ausführungsformen nach Abb. i und 2 beide Scheiben im gleichen Sinne umlaufen, ist die Anordnung nach Abb. 3 so .getroffen, daß die Scheiben entgegengesetzten Drehsinn haben.In all three embodiments, the one connecting the two panes is used Belt. guided over a guide roller i, which is arranged so that the smaller disc 2 is caught about halfway by the belt. The guide pulley i can either, as in Fig. I, run on a special bolt 3 or, as Fig. 2 and 3 show, on an axis d. be arranged around which the smaller disk 2 swings. While in the embodiments according to fig. i and 2 both discs rotate in the same sense, the arrangement according to Fig. 3 is so .getragt that the discs are opposite Have the sense of rotation.
