Description

Bekanntlich darf die Spannung der Antriebsketten der Steuerwellen von Explosionsmotoren nicht zu groß sein, wenn unzulässige Beanspruchungen vermieden werden sollen. Die bei geringeren Umlaufgeschwindigkeiten günstigste Kettenspann nung erweist sich aber bei steigender Umlaufzahl und den dementsprechendzunehmendenFliehkräften der Kette als ungenügend. Die Erfindung bezweckt nun eine selbsttätige Anpassung der Ketterispannung an die jeweilige Umlaufzahl des Explosionsmotors.As is well known, the tension of the drive chains of the control shafts is allowed of explosion engines should not be too large if impermissible stresses are avoided should be. The most favorable chain tension at lower circulating speeds However, the increase in circulation and the correspondingly increasing centrifugal forces the chain as insufficient. The invention now aims at an automatic adaptation the chain tension to the respective number of revolutions of the explosion engine.

Gemäß ,der Erfindung ist die Kettenspannrolle an einem beweglichen, unter Einfluß des Schmieröldruckes des Motors stehenden Glied gelagert.According to the invention, the chain idler is on a movable, stored member standing under the influence of the lubricating oil pressure of the engine.

In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt.The drawing shows an example embodiment of the subject matter of the invention shown.

Die Kettenspannrolle i für die Kette 2 ist im gegabelten Ende 3 eines Kolbens 4 gelagert, der in einem Zylinder 5 längs verschiebbar eingesetzt ist. Um den Zylinder 5 ist eine Schraubenfeder 6 angeordnet, die unten an der die Zylinderbasis bildenden Wandung des Motorgehäuses abgestützt ist und oben an einem Wulst des Kolbens 4 angreift und die Rolle i mit einer voribesti,mmten Anfangsspannung an die Kette 2 .drückt. Der Zylinder 5 steht über ein Rückschlagventil 7 mit der Schmieröldruckieitung 8 in Verbindung. Der Kolben 4 weist einen durchgehenden Kanalg auf, welcher mit einem einstellbaren Überdruckventil io versehen ist. Die Ausmündung ,dieses Kanals g ist gegen das Lager der Spannrolle 2 ,gerichtet, so daß bei unzulässig hohem Öldruck durch das entsprechend eingestellte Ventil io entweichendes Öl gegen das Lager i i dieser Spannrolle spritzt und. zum Schmieren dient. Am Druckraum des Zylinders kann noch ein Entspannungsventil angebracht sein, um die Kette 6 z. B. zwecks Demontage ganz entspannen zu können.The chain idler i for the chain 2 is one in the forked end 3 Piston 4 mounted, which is inserted in a cylinder 5 so as to be longitudinally displaceable. Around the cylinder 5 is arranged a coil spring 6, which is below the cylinder base forming wall of the motor housing is supported and above on a bead of the piston 4 attacks and the role i with a voribesti, mmten initial tension on the chain 2 .presses. The cylinder 5 is connected to the lubricating oil pressure line via a check valve 7 8 in connection. The piston 4 has a continuous channel, which with an adjustable pressure relief valve is provided. The mouth of this canal g is directed against the bearing of the tension roller 2, so that in the event of an impermissibly high oil pressure through the appropriately set valve io, oil escaping against the bearing i i this tension pulley splashes and. serves for lubrication. At the pressure chamber of the cylinder can still be a relief valve attached to the chain 6 z. B. for the purpose of dismantling to be able to relax completely.

Zur Spannungsregelung der Kette könnte anstatt des in einem Druckzylinder verschiebbaren Kolbens auch eine andere Vorrichtung, z. B. eine durch Membranen. abgeschlossene Expansionsdose oder ein gekrümmtes Rohr, benutzt werden, deren Innenraum mit der Schmierdruc'kleitung und deren durch Dehnung bzw. Aufbiegung bewegtes Glied mit der Spannrolle in Verbindung steht.To regulate the tension of the chain could instead be in a pressure cylinder displaceable piston also another device, e.g. B. one through membranes. closed expansion box or a curved pipe, the interior of which can be used with the lubricant pressure line and its member moved by stretching or bending is in connection with the tensioner pulley.
