Abstract
Ölversorgung eines Pleuellagers (3), dadurch gekennzeichnet, dass das seitlich am Hauptlager austretende Öl über ein Auffangblech (7) zum Pleuellager geführt wird.oil supply a connecting rod bearing (3), characterized in that the side at the main bearing escaping oil over Collecting plate (7) is guided to the connecting rod bearing.
Description
Die vorliegende Erfindung betrifft die Ölversorgung von einem Pleuelzapfen, vorzugsweise ein Kurbelwellenpleuellager, gemäß den Merkmalen der aufgeführten Ansprüche.The The present invention relates to the supply of oil from a crankpin, preferably a Kurbelwellenpleuellager, according to the features of the claims listed.
Kurbelwellenhauptlagerungen sind vornehmlich gleitgelagert. Die Ölversorgung der Pleuellager wird über die Hauptlagerstelle der Kurbelwelle durch Ölbohrungen bewerkstelligt.Crankshaft main bearings are mainly sliding. The oil supply of the connecting rod bearings will over the main bearing point of the crankshaft accomplished by oil drilling.
Wenn die Kurbelwellenhauptlager in Wälzlagern aufgenommen und die Pleuellager weiterhin in Gleitlagern laufen sollen, muss das Gleitlager weiterhin mit Drucköl versorgt werden. Da die in den Hauptlagern mündenden Ölbohrungen von der Hauptölgalerie auf Umgebungsdruck gefordert werden, kann das Öl von hier aus nicht durch Ölbohrungen vom Hauptlager zu den Pleuellagern gelangen. Das Öl tritt zwischen den Wälzkörpern aus.If the main crankshaft bearings in rolling bearings taken up and the connecting rod bearings continue to run in plain bearings should, the plain bearing must continue to be supplied with pressure oil. Since the in the main bearings opening oil wells from the main oil gallery can be demanded to ambient pressure, the oil from here can not through oil wells from the main bearing to the connecting rod bearings. The oil comes between the rolling elements.
Es existieren Ansätze, die durch eintauchen eines Rohres in das Ölbad, welches am Pleuelfuß befestigt ist, die Ölförderung zum Pleuellager realisieren sollen. Dieser Ansatz ist aber bei nicht ausreichendem Ölstand (Kurvenfahrt, hohe Beschleunigungen) nicht funktionsfähig.It exist approaches, by immersing a tube in the oil bath, which attached to the connecting rod is, the oil extraction to realize the connecting rod bearing. But this approach is not sufficient oil level (Cornering, high accelerations) not functional.
Der Erfindung liegt nun die Aufgabe zu Grunde, diese Nachteile aus der Welt zu schaffen.Of the Invention is now the object of these disadvantages from the To create the world.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, indem die am Kurbelwellenhauptlager ankommenden Ölströme seitlich am Hauptlager geführt und durch die Wange in eine Ölbohrung, welches am Hubzapfen endet, geleitet werden.These Task is according to the invention solved by by the oil flows arriving at the crankshaft main bearing are guided laterally on the main bearing and through the cheek into an oil well, which ends at the crank pin, are passed.
Die Umsetzung von Wälzlagerungen ist im Motorenbau wegen ihrer Vorteile in der Triebwerksreibung sehr willkommen. Durch die Lagerung der Kurbelwelle und der Pleuel im Wälzlagern sinkt zudem der Druckölbedarf drastisch, so dass die Ölpumpe kleiner gebaut werden kann und so weitere Einsparpotentiale vortreten. Um aber die Montage zu ermöglichen, müssen entweder die Wälzlagerkäfige oder die Kurbelwelle geteilt ausgeführt werden. Die Zweiteilung der Hauptlagerkäfige scheint technisch die unproblematische zu sein, da bei den geteilten Pleuellagerkäfigen erhebliche Dauerfestigkeitsprobleme auftauchen, die aufgrund der zusätzlich auf die Lagerkäfige wirkenden Fliehkraft, diese zusätzlich stark belasten.The Implementation of rolling bearings is in engine construction because of its advantages in engine friction very welcome. Due to the bearing of the crankshaft and the connecting rod in rolling bearings In addition, the pressure oil requirement decreases drastically, so the oil pump can be built smaller and thus further savings potentials occur. But to enable the assembly have to either the rolling bearing cages or the crankshaft split executed become. The division of the main storage cages seems technically the to be unproblematic, since the shared conrod cages considerable Fatigue problems arise due to the addition of the camp cages acting centrifugal force, this additionally strong strain.
Für den Fall des kompletten Wälzlagereinsatzes auf Haupt- und Pleuellagern werden keine Druckölbohrungen für die Lagerstellen benötigt.In the case of the complete roller bearing insert on main and conrod bearings are no pressure oil holes for the bearings needed.
Eine Alternative stellt die Wälzlagerung der Hauptlager und Gleitlagerung der Pleuellager dar. Damit kann der Wälzlagerkäfig der Kurbelwellenhauptlager geteilt ausgeführt werden und die Pleuellager werden weiterhin gleitgelagert. Die Kurbelwelle kann einteilig ausgeführt werden, so dass die Kosten im Rahmen des zulässigen bleiben. Hier stellt sich nun die Frage nach dem Transport des Drucköls zu den Pleuellagern.A Alternative is the rolling bearing the main bearing and plain bearing of the connecting rod bearing dar. So that can the rolling bearing cage of Crankshaft main bearings are split and the connecting rod bearings will continue to slide. The crankshaft can be made in one piece, so the costs stay within the allowed range. Here poses Now the question of the transport of the pressure oil to the connecting rod bearings.
Hier wird nun vorgeschlagen, weiterhin an die Hauptlagerstelle Drucköl zu befördern. Dieses Öl. tritt dann seitlich aus der Lagerstelle aus und kann geführt, aufgefangen und über die Wangen zum Hubzapfen gelangen. Dafür wird die Fliehkraft, dem das Öl ausgesetzt ist, genutzt. Das nach außen geschleuderte Öl wird in einem labyrinthartigem Blech in der Wange sitzend aufgefangen und in eine Ölbohrung weiter geleitet.Here It is now proposed to continue to transport pressure oil to the main storage facility. This oil. occurs then laterally out of the bearing and can be guided, collected and over the cheeks get to the crankpin. For the centrifugal force, the the oil exposed, used. The thrown outward oil is in a labyrinthine sheet metal caught in the cheek and continue into an oil well directed.
Das Öl der Hauptlagerstelle kann entweder durch die Wälzkörper geführt werden (Kühlung!) und/oder vorher seitlich umgelenkt und zum Auffangblech geführt werden. Der geteilte Außenring des Wälzlagers kann ein Teil der Labyrinthfunktion übernehmen. Je nach Anwendung und vorhandenem Platz, kann das Auffangblech sektional ausgeführt werden. Dieses Blech wird entsprechend geformt und kann als Einpressteil geformt sein.The oil of the main bearing can either be guided by the rolling elements (Cooling!) And / or previously deflected laterally and guided to the collecting tray. The split outer ring of the rolling bearing can take over part of the maze function. Depending on the application and existing space, the collecting plate can be executed section. This sheet is shaped accordingly and can as Einpressteil be shaped.
