Description
Die Erfindung betrifft eine Vorrichtung zur Schmierung von Kurbelwellen- und Pleuellagern einer Kurbelwelle einer Brennkraftmaschine gemäß dem Oberbegriff des Anspruchs 1, sowie eine Kurbelwelle gemäß dem Oberbegriff des Anspruchs 19.The The invention relates to a device for lubricating crankshaft and connecting rod bearings of a crankshaft of an internal combustion engine according to the preamble of claim 1, and a crankshaft according to the preamble of the claim 19th
Zur Schmierung von Kurbelwellen- und Pleuellagern einer Kurbelwelle einer Brennkraftmaschine ist es bereits bekannt, Schmieröl durch Schmierölbohrungen eines Kurbelgehäuses zu den Lagerflächen der Kurbelwellenlager zuzuführen, von wo aus das Schmieröl durch Schmierölbohrungen im Inneren der Kurbelwelle zu einem oder zwei benachbarten Pleuellagern gelangt. Die Schmierölbohrungen in der Kurbelwelle können dabei verschiedene Anordnungen oder Ausrichtungen besitzen. Dort, wo die Wellenzapfen und/oder Hubzapfen der Kurbelwelle zur Verringerung der rotierenden Massen der Kurbelwelle mit sogenannten Erleichterungs- oder Entlastungsbohrungen versehen sind, ist es jedoch erforderlich, die Schmierölbohrungen exzentrisch an den Erleichterungs- oder Entlastungsbohrungen vorbei zu führen, um einen Austritt des Schmieröls durch die Erleichterungs- oder Entlastungsbohrungen zu verhindern. In diesem Fall muss allerdings der Durchmesser der Erleichterungs- oder Entlastungsbohrungen relativ klein gehalten werden, damit daneben noch ausreichend Platz für die Schmierölbohrungen vorhanden ist. Dadurch wird jedoch die Wirkung der Erleichterungs- oder Entlastungsbohrungen eingeschränkt. Außerdem müssen die Schmierölbohrungen sehr genau und mit geringen Toleranzen gebohrt werden.to Lubrication of crankshaft and connecting rod bearings of a crankshaft an internal combustion engine, it is already known, lubricating oil Oil drilling a crankcase to the storage areas to feed the crankshaft bearing, from where the lubricating oil through oil drilling inside the crankshaft to one or two adjacent connecting rod bearings arrives. The oil holes in the crankshaft can have different arrangements or alignments. There, where the shaft journals and / or crank pins of the crankshaft to reduce the rotating masses of the crankshaft with so-called or relief wells, it is however necessary to the oil holes eccentrically past the relief or relief holes to lead, to a leakage of the lubricating oil through the relief or relief holes. In this case, however, the diameter of the facilitation or relief holes are kept relatively small, so next to it enough space for the oil holes available is. This, however, becomes the effect of the relief or relief wells limited. Furthermore have to the oil holes be drilled very accurately and with small tolerances.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zur Schmierung von Kurbelwellen- und Pleuellagern einer Kurbelwelle einer Brennkraftmaschine sowie eine Kurbelwelle der eingangs genannten Art dahingehend zu verbessern, dass die Herstellung der Kurbelwelle und die Schmierung der Pleuellager erleichtert werden kann.outgoing This is the object of the invention, a device for the lubrication of crankshaft and connecting rod bearings of a crankshaft an internal combustion engine and a crankshaft of the aforementioned Art to improve that the production of the crankshaft and the lubrication of the connecting rod bearing can be facilitated.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass mindestens ein Teil der Erleichterungs- oder Entlastungsbohrung des Wellenzapfens als Schmierölkammer genutzt wird, die durch Schmierölkanäle mit dem Kurbelwellenlager und dem oder den benachbarten Pleuellagern kommuniziert.These Task is inventively characterized solved, that at least part of the relief or relief well of the journal as a lubricating oil chamber is used, which by lubricating oil channels with the Crankshaft bearing and the or the adjacent connecting rod bearings communicates.
Eine solche Schmierölkammer lässt sich erheblich einfacher durch Schmierölkanäle in Form von Schmierölbohrungen mit dem benachbarten Pleuellager oder den benachbarten Pleuellagern verbinden als die Lageroberfläche des Wellenlagers.A such lubricating oil chamber let yourself considerably easier due to lubricating oil channels in the form of lubricating oil bores with the adjacent connecting rod bearing or the adjacent connecting rod bearings connect as the bearing surface of the shaft bearing.
Gemäß einer ersten bevorzugten Erfindungsalternative ist die Schmierölkammer durch einen Schmierölkanal direkt mit dem Pleuellager verbunden, wobei in diesem Fall der Schmierölkanal exzentrisch durch einen das Pleuellager tragenden Hubzapfen der Kurbelwelle hindurch verläuft und an einer Lagerfläche des Pleuellagers mündet.According to one The first preferred alternative of the invention is the lubricating oil chamber through a lubricating oil channel directly connected to the connecting rod bearing, in which case the lubricating oil channel eccentric by a connecting rod bearing bearing crankpin of the crankshaft passes through and on a storage area of the connecting rod bearing opens.
Alternativ dazu kann die Schmierölkammer jedoch auch durch einen Schmierölkanal mit einer weiteren Schmierölkammer verbunden sein, die in einer Erleichterungs- oder Entlastungsbohrung des Hubzapfens angeordnet ist und zweckmäßig durch mindestens einen radial durch den Hubzapfen zur Lagerfläche des Pleuellagers verlaufenden Schmierölkanal mit der Lagerfläche des Pleuellagers kommuniziert. Die Schmierölkanäle sind in allen Fällen bevorzugt als geradlinige Schmierölbohrungen ausgebildet.alternative However, the lubricating oil chamber can do this also through a lubricating oil channel with another lubricating oil chamber Being connected in a relief or relief well the crank pin is arranged and expediently by at least one radially with the crankpin to the bearing surface of the connecting rod bearing extending lubricating oil channel the storage area of the connecting rod bearing communicates. The lubricating oil channels are preferred in all cases designed as a straight lube oil holes.
Um einen Austritt des Schmieröls aus der Erleichterungs- oder Entlastungsbohrung zu verhindern, ist vorzugsweise mindestens ein Einsatz in der Bohrung montiert, der zusammen mit einer Innenwand der Bohrung die Schmierölkammer begrenzt.Around a leakage of the lubricating oil from the relief or relief hole is to prevent preferably at least one insert mounted in the bore, the along with an inner wall of the bore, the lubricating oil chamber limited.
Der Einsatz kann zweckmäßig die Form einer Hülse aufweisen, die sich durch die zur Achse des Kurbelwellen- bzw. Pleuellagers koaxiale Erleichterungs- oder Entlastungsbohrung hindurch erstreckt und die ringförmige Schmierölkammer an deren innerem Umfang begrenzt, während der äußere Umfang der Schmierölkammer von der Innenwand der Bohrung gebildet wird. Zur Minimierung von Spannungsspitzen in der Kurbelwelle weist die Erleichterungs- oder Entlastungsbohrung zweckmäßig zwei entgegengesetzte verengte Endabschnitte und einen zwischen den Endabschnitten angeordneten erweiterten Mittelabschnitt auf, in dem sich die Schmierölkammer befindet. Der hülsenförmige Einsatz und die beiden Endabschnitte der Erleichterungs- oder Entlastungsbohrung liegen vorzugsweise mit Presssitz dichtend gegeneinander an, wobei die Abdichtung durch eine zwischen den Endabschnitten des Einsatzes und der Bohrung angeordnete Ringdichtung weiter verbessert werden kann.Of the Use may be appropriate Shape of a sleeve have, extending through the axis of the crankshaft or connecting rod bearing coaxial relief or relief bore extends therethrough and the annular ones Oil chamber limited at the inner periphery, while the outer circumference of the lubricating oil chamber is formed by the inner wall of the bore. To minimize voltage spikes in the crankshaft has the relief or relief hole expedient two opposite narrowed end portions and one between the end portions arranged extended central portion, in which the lubricating oil chamber located. The sleeve-shaped insert and the two end portions of the relief or relief bore are preferably with a press fit sealingly against each other, wherein the Sealing by a between the end portions of the insert and the bore arranged ring seal can be further improved.
