Description
Vorrichtung zum Dämpfen des Kegelradgeräusches an Brennkraftmaschinen Gegenstand der Erfindung ist eine Vorrichtung zur Dämpfung des Kegelradgeräusches an Brennkraftmaschinen, insbesondere für Kraftzweiräder, bei welchen die Nockenwelle um 9o° zur Kurbelwelle versetzt liegt und durch Kegelräder angetrieben wird. Das Wesen der Erfindung besteht darin, daß auf das das Kegelrad tragende Ende der Nockenwelle unter Einschaltung einer Antriebsschnecke für die Ölpumpe eine Stellvorrichtung als Gegenlager für eine axiale Verschiebung der Welle einwirkt, damit die Zahnflanken des Nockenwellenzahnrades mit denen des Kurbelwelllenzahnrades ständig in Berührung bleiben. Je nach der Abnutzung der Zähne kann also die Nockenwelle durch die Stellvorrichtung so weit verschoben werden, daß der Fingriff beider Kegelzahnräder wieder geregelt und das Zahnradgeräusch beseitigt wird. Dabei besteht der Vorteil, daß dieses Regeln bei laufendem Motor unter Abhören desselben vorgenommen werden kann, mithin eine Außerbetriebsetzung und Auseinandernehmen desselben nicht erfordert.Device for damping the bevel gear noise on internal combustion engines The invention relates to a device for damping the bevel gear noise on internal combustion engines, in particular for motorcycles, in which the camshaft is offset by 90 ° to the crankshaft and is driven by bevel gears. That The essence of the invention is that on the end of the camshaft bearing the bevel gear with the involvement of a drive worm for the oil pump an adjusting device acts as a counter bearing for an axial displacement of the shaft, so that the tooth flanks of the camshaft gear is in constant contact with those of the crankshaft gear stay. Depending on the wear and tear on the teeth, the camshaft can be controlled by the adjusting device be shifted so far that the finger grip of both bevel gears is regulated again and the gear noise is eliminated. The advantage here is that these rules can be carried out with the engine running while listening to it, hence one Does not require decommissioning and disassembly.
Zwischen der Stellvorrichtung und dem Nockenwellenende ist eine Antriebsschnecke für die Ölpumpe eingeschaltet, welche aus der Welle herausgebildet ist, während das Wellenlager als Pumpengehäuse dient.A drive worm is located between the adjusting device and the end of the camshaft switched on for the oil pump, which is formed from the shaft, while the shaft bearing serves as a pump housing.
Auf der Zeichnung ist eine beispielsweise Ausführungsform des Nockenwellenantriebs dargestellt, es zeigt: Abb. z einen senkrechten Schnitt durch das Gehäuse mit einer Seitenansicht des Antriebes und Abb.2 einen Querschnitt durch das Gehäuse mit Draufsicht des Antriebes.The drawing shows an example of an embodiment of the camshaft drive shown, it shows: Fig. z a vertical section through the housing with a Side view of the drive and Fig. 2 a cross section through the housing with a top view of the drive.
Auf der Kurbelwelle a des Einzylinder motors ist das Kegelrad b befestigt, in welches das Kegelrad c der Nockenwelle d eingreift. Auf der rechten Seite ist mit der Nockenwelle d die Antriebsschnecke e für die Ölpumpe als Ganzes -verbunden, während durch die Druckschraube f unter Einschaltung einer Kugel die Nockenwelle d von außen verstellt und der Eingriff des Kegelrades c in das Kegelrad b geregelt werden kann. Auf der gegenüberliegenden Seite ist die Nockenwelle d mit der Innenkupplung g für den Magneten h versehen.The bevel gear b is attached to the crankshaft a of the single-cylinder engine, in which the bevel gear c of the camshaft d engages. On the right is with the camshaft d the drive worm e for the oil pump as a whole - connected, while the camshaft is actuated by the pressure screw f with the involvement of a ball d adjusted from the outside and the engagement of the bevel gear c in the bevel gear b is regulated can be. On the opposite side is the camshaft d with the internal clutch g for the magnet h.
