Abstract
Kettentrieb (20) für die Verbindung des Kettenrads (1) einer Antriebswelle (4) mit dem Kettenrad (2) einer Nebenwelle (5) für ein Nebenaggregat an Brennkraftmaschinen, wobei die Antriebswelle (4) eine größere Trägheitsmasse als die Nebenwelle (5) hat und das Kettenrad (2) der Nebenwelle (5) einen Radialtilger (9) hat, der gegenphasig zu der vom Kettenrad (1) der Antriebswelle (4) bewirkten periodischen Anregung der Nebenwelle (5) schwingt, dadurch gekennzeichnet, dass der Kettentrieb (20) neben dem Kettenrad (2) der Nebenwelle (5) mit weiteren Kettenräder (3) von Nebenwellen (6) und/oder Umlenkkettenrädern (17) ausgestattet ist, und die Schwingungsrichtung des Radialtilgers (9) sich im Wesentlichen in Richtung einer Kraftresultierenden (10) aus den an dem Kettenrad (2) des Radialtilgers (9) auftretenden Kräften erstreckt.Chain drive (20) for the connection of the sprocket (1) of a drive shaft (4) with the sprocket (2) of a secondary shaft (5) for an accessory to internal combustion engines, wherein the drive shaft (4) has a larger inertial mass than the secondary shaft (5) and the sprocket (2) of the secondary shaft (5) has a radial damper (9) which oscillates out of phase with the periodic excitation of the secondary shaft (5) caused by the sprocket (1) of the drive shaft (4), characterized in that the chain drive (20 ) is provided next to the sprocket (2) of the secondary shaft (5) with other sprockets (3) of secondary shafts (6) and / or Umlenkkettenrädern (17), and the direction of vibration of the Radialtilgers (9) substantially in the direction of a force resulting (10 ) extends from the forces acting on the sprocket (2) of the Radialtilgers (9).
Description
Technisches GebietTechnical area
Die vorliegende Erfindung befasst sich mit einem Kettentrieb, insbesondere für die Verbindung des Kettenrads einer Antriebswelle mit dem Kettenrad einer Nebenwelle für ein Nebenaggregat an Brennkraftmaschinen, wobei die Antriebswelle eine größere Trägheitsmasse als die Nebenwelle hat und das Kettenrad der Nebenwelle einen Radialtilger hat, der gegenphasig zu der vom Kettenrad der Antriebswelle bewirkten periodischen Anregung der Nebenwelle schwingt.The present invention is concerned with a chain drive, in particular for the connection of the sprocket of a drive shaft to the sprocket of a secondary shaft for an internal combustion engine, wherein the drive shaft has a larger inertial mass than the secondary shaft and the sprocket of the secondary shaft has a Radialtilger, the opposite in phase caused by the sprocket of the drive shaft periodic excitation of the secondary shaft oscillates.
Radialtilger werden bei Kettenrädern von Nebenwellen zur Reduktion der in die Welle eingeleiteten Schwingungen, hervorgerufen durch einen Polygoneffekt der Kette, eingesetzt. Hierdurch wird eine Dämpfung von Schwingungen und auch von Geräuschen erreicht.Radial dampers are used in sprockets of spurs to reduce the vibrations introduced into the shaft, caused by a polygonal effect of the chain. As a result, an attenuation of vibrations and noise is achieved.

Durch die
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen Kettentrieb mit geringer Geräuschbildung zu schaffen, bei dem von der Antriebswelle aus über eine Kette gleichzeitig mehrere Kettenräder von Nebenaggregaten angetrieben werden. Der Kettentrieb soll in seinem Aufbau möglichst einfach und kostengünstig sein.The invention has for its object to provide a chain drive with low noise, in which from the drive shaft via a chain at the same time several sprockets are driven by ancillaries. The chain drive should be as simple and inexpensive as possible in its construction.
Die Lösung der gestellten Aufgabe wird mit den Merkmalen des Anspruchs 1 erreicht. Die sich an den Anspruch 1 anschließenden Unteransprüche 2 bis 4 geben vorteilhafte Ausbildungen des Kettentriebs mit den Merkmalen des Anspruchs 1 wieder.The solution of the problem is achieved with the features of claim 1. The adjoining to claim 1
Bei dem neuen Kettentrieb sind mehrere Kettenräder für Nebenwellen vorhanden. Darüber hinaus können Umlenkkettenräder für die Umlenkung der Kette vorgesehen sein. Mindestens eines der Kettenräder für die Nebenantriebe ist mit einem Radialtilger versehen, dessen Schwingungsrichtung im Wesentlichen in Richtung der Kraftresultierenden aus den an diesem Kettenrad anliegenden Kräften ausgerichtet ist. Bevorzugt wird der Radialtilger in dem der Antriebswelle nächstliegenden Kettenrad im Zugtrumen angeordnet.In the new chain drive several sprockets for sprockets are available. In addition, Umlenkkettenräder may be provided for the deflection of the chain. At least one of the sprockets for the auxiliary drives is provided with a Radialtilger whose direction of vibration is aligned substantially in the direction of the force resulting from the forces applied to this sprocket. Preferably, the Radialtilger is arranged in the drive shaft closest to the sprocket in Zugtrumen.
Es ist günstig, wenn der Kettentrieb mit wenigstens einer Führungseinrichtung für die Kette versehen ist. Auch können Spanneinrichtungen für die Kette eingesetzt werden.It is favorable if the chain drive is provided with at least one guide device for the chain. Also, clamping devices can be used for the chain.
Von Vorteil ist, wenn die Antriebswelle außerhalb der Kette und die mit dem Radialtilger versehene Nebenwelle innerhalb der Kette angeordnet ist. Diese Anordnung ist äußerst platzsparend.It is advantageous if the drive shaft is arranged outside the chain and the secondary shaft provided with the radial absorber within the chain. This arrangement is extremely space-saving.
