Description

Schmiereinrichtung für die Kurbelwelle von Brennkraftmaschinen Die Erfindung betrifft eine Schmiereinrichtung für die Kurbelwelle von Brennkraftmaschinen mit als Wälzlager ausgebildetem Hauptendlager. Es war bisher üblich, die gesamte Schmiermittelmenge, welche - zur Schmierung der Kurbelwelle, d. h. der auf der Kurbelwelle befindlichen Lagerungen, vorzusehen ist, in eines der Hauptendlager zu leiten. Von diesem Lager aus strömte das Schmiermittel sodann zu den weiteren Lagerungen.Lubricating device for the crankshaft of internal combustion engines The invention relates to a lubricating device for the crankshaft of internal combustion engines with main end bearing designed as a roller bearing. So far it has been customary to do the entire Amount of lubricant which - to lubricate the crankshaft, d. H. the one on the crankshaft The storages located there should be directed to one of the main repositories. from The lubricant then flowed from this bearing to the other bearings.

Eine derartige Schmiereinrichtung hat den Nachteil, daß insbesondere bei großen Schmiermittelmengen eine starke Schaumbildung des Schmiermittels in dem Hauptendlager auftritt. Die Folge davon ist die Bildung von Luftsäcken in dem Schmiermittelstrom. Diese Luftsäcke werden zusammen mit dem Schmiermittel weitergeleitet. Die durch die Luftsäcke bedingte unregelmiil:,ige Förderung des Schmiermittels hat aber eine unzulängliche Schmierung einzelner Lager der. Kurbelwelle zur Folge; denn die Schmierung wird durch die mitgeführten Luftsäcke 'zeitweise unterbrochen.Such a lubricating device has the disadvantage that in particular if large quantities of lubricant are used, the lubricant will foam heavily in the Main repository occurs. The consequence of this is the formation of air pockets in the lubricant flow. These air sacs are passed along with the lubricant. By The air sacs caused irregularities, but the lubricant was conveyed in some way Inadequate lubrication of individual bearings in the. Crankshaft result; because the lubrication is temporarily interrupted by the air bags being carried.

Es ist Aufgabe der Erfindung, eine Schmiercinrichtung für die Kurbelwelle von Brennkraftmaschinen zu schalten, welche die Nachteile bekannter Einrichtungen dieser Art vermeidet.It is the object of the invention to provide a lubricating device for the crankshaft to switch of internal combustion engines, which the disadvantages of known devices this type avoids.

Die gestellte Aufgabe wird gemäß der Erfindung dadurch gelöst, daf:) eine ülleitung, die in den äußeren Laufring des Wälzlagers einmündet, sich im Inneren des Laufringes in zwei Leitungen teilt, von denen die eine mit engem Querschnitt an die Schmierstellen des Lagers führt, so daß lediglich die zur Schmierung dieses Lagers notwendige Schmiermittelinenge hindurchfließen kann. Die andere Leitung führt mit einem größeren Querschnitt zu einem an der Kurbelwelle sitzenden Sammelring üblicher Art, wobei der Querschnitt dieser Leitung so bemessen ist, daß die restliche Schmiermittelmenge hindurchströmen kann.The problem posed is achieved according to the invention in that: an oil line, which opens into the outer race of the roller bearing, is located inside of the raceway divides into two lines, one of which has a narrow cross-section leads to the lubrication points of the bearing, so that only the lubrication of this The required amount of lubricant can flow through the bearing. The other line leads with a larger cross-section to one sitting on the crankshaft Collecting ring of the usual type, the cross section of this line is dimensioned so that the remaining amount of lubricant can flow through.

Die Zeichnung zeigt den Mittelquerschnitt durch den im Bereich eines Hauptendlagers liegenden Teil einer Kurbelwelle einer Kolbenbrennkraftmaschine mit einer Ausführungsform der erfindungsgemäßen Schmiereinrichtung.The drawing shows the central cross-section through the in the area of a Main end bearing lying part of a crankshaft of a piston internal combustion engine with an embodiment of the lubricating device according to the invention.

Für die gesamte zur Schmierung der auf der Kurbelwelle .4 befindlichen Lager dienende Schmiermittelmenge ist eine Leitung i im Gehäuse 2 eines Lagers 3 vorgesehen. Das Lager 3 ist ein Hauptendlager der Kurbelwelle und ist als Wälzlager ausgebildet. Die Leitung i mündet in dem äußeren Tragring 5 des Lagers 3 und teilt sich im Inneren dieses Tragringes 5 in zwei Leitungen 6 und 7. Die Leitung 6 führt an die Schmierstellen des Lagers 3. Der Querschnitt dieser Leitung ist durch einen Einsatzteil ö, welcher eine düsenartige Durchbohrung 8u besitzt, so bemessen, daß lediglich die zur Schmierung des Hauptendlagers 3 notwendige kleinere Schmiermittelmenge hindurchströmen kann. Die Leitung 7 führt zu einem Sammelring 9, welcher in vorteilhafter Ausgestaltung als ringförmige Ausnehmung in der Wange io der auf das Hauptendlager 3 folgenden Kurbelkröpfung i i ausgebildet ist.For the entire lubrication of the .4 located on the crankshaft The amount of lubricant used for bearings is a line i in the housing 2 of a bearing 3 intended. The bearing 3 is a main end bearing of the crankshaft and is used as a roller bearing educated. The line i opens into the outer support ring 5 of the bearing 3 and divides inside this support ring 5 in two lines 6 and 7. The line 6 leads to the lubrication points of the bearing 3. The cross-section of this line is through a Insert part ö, which has a nozzle-like through hole 8u, dimensioned so that only the smaller amount of lubricant necessary to lubricate the main end bearing 3 can flow through. The line 7 leads to a collecting ring 9, which is advantageous Design as an annular recess in the cheek io the on the main end bearing 3 following crank crank i i is formed.

Zweckmäßig werden die Schmierstellen des Lagers 3 mit dem Sammelring 9 durch eine weitere Leitung 12 verbunden, so daß die zur Schmierung des Hauptendlagers 3 dienende Schmiermittelmenge nach erfolgter Schmierung des Lagers mit der restlichen, durch die Leitung ; strömende Schmiermittelmenge 6 vereinigt wird. Von dort wird die gesamte Schiniermittelmenge zu den weiteren nicht gezeichneten Schmierstellen der Kurbelwelle «eitergeleitet.The lubrication points of the bearing 3 with the collecting ring are expedient 9 connected by another line 12, so that the lubrication of the main end bearing 3 serving amount of lubricant after lubrication of the bearing with the remaining, through the line; flowing amount of lubricant 6 is combined. From there it will the total amount of lubricant to the other lubrication points not shown of the crankshaft.

Eine Schmiereinrichtung gemäß vorliejender Erfindung hat den Vorteil, daß auch bei sehr großen Schmiermittelmengen, wie sie z. B. bei Hochleistungskolbenbrennkraftmaschinen hoher Drehzahl notwendig sind, eine einwandfreie Schmierung aller auf der Kurbelwelle der Kolbenbrennkraftmaschine vorgesehenen Lager gewährleistet ist.A lubricating device according to the present invention has the advantage that even with very large amounts of lubricant, as z. B. in high-performance piston internal combustion engines high speed, proper lubrication of everything on the crankshaft is necessary the piston internal combustion engine provided bearing is guaranteed.
