Description

Die Erfindung"betrifft eine Einrichtung zum Einführen von Schmieröl in die Ölführungskanäle umlaufender Wellen, insbesondere der Kurbelwellen von Brennkraftmaschinen zum Zweck der Schmierung der Pleuellager.The invention "relates to a device for introducing lubricating oil in the oil ducts of rotating shafts, in particular the crankshafts of internal combustion engines for the purpose of lubricating the connecting rod bearings.

Die Erfindung besteht darin, daß zwischen dem ortsfesten ölzuführungsraum und der Welle ein gegen Drehen gesicherter, mit Öldurchtrittsöffnungen versehener Ölzutrittsring eingeschaltet ist, der in den Wänden des Olzuführungsraumes dicht und nachgiebig, z. B. mittels elastischer Weichpackungen, Simmeringen, Stulpdichtungen od. dgl., gelagert ist und die Welle mit dem geringstmöglichen Lagerspiel umfaßt.The invention consists in that between the stationary oil supply space and the shaft is secured against rotation and provided with oil passage openings Oil inlet ring is switched on, which is tight in the walls of the oil supply space and compliant, e.g. B. by means of elastic soft packings, Simmeringen, face seals Od. Like., Is stored and includes the shaft with the smallest possible bearing play.

Durch die nachgiebige Lagerung des ÖlzufÜhrungsringes im Ölführungsgehäuse vermag der Ring zwanglos den durch die Durchbiegung hervorgerufenen Ausschlägen der Welle, zu folgen. Bei der Bemessung des Laufspiels zwischen dem Ölzuführungsring und der Welle kann deshalb die Durchbiegung letzterer unberücksichtigt bleiben, so daß das kleinstmögliche Laufspiel und damit eine sehr gute Dichtheit zwischen Ring und Welle durchführbar ist. Die Weichpackungen sind keinem Verschleiß ausgesetzt, da sie lediglich zwei ruhende Teile gegeneinander abzudichten haben.Due to the flexible mounting of the oil feed ring in the oil guide housing the ring can easily handle the deflections caused by the deflection to follow the wave. When dimensioning the running clearance between the oil feed ring and for the shaft, the deflection of the latter can therefore be disregarded, so that the smallest possible running clearance and thus a very good tightness between Ring and shaft is feasible. The soft packs are not subject to wear and tear, since they only have to seal two stationary parts against each other.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Schnitt dargestellt. Die Kurbelwelle a ragt mit ihrem- Zapfen b in den Schmieröl ztIführungsraum c hinein. Zwischen Zapfen b und Raum c ist ein Ölführungsring d eingeschaltet. Dieser- ist mittels.Stulpdichtungen, Simmeringen od. dgl. Weichpackungen e, e' in den Wänden des Olzuführungsraumes c dicht und nachgiebig gelagert. Der Ölzuführungsring weist den Öleintrittsöffnungen f des Wellenzapfens b gegenüberliegende Durchbrechungen g für den Zutritt des Schmieröls auf und umfaßt den Zapfen mit dem kleinstmöglichen Lagerspiel. Es ist z. B. ein Lagerspiel von nur o,o4 bis 0,05 mm durchführbar, wenn der Ölzuführungsring eine Auskleidung h aus Weißmetall erhält. Ein Stift i sichert den Ring d gegen Drehen.In the drawing, an exemplary embodiment of the subject matter of the invention is shown in section. The crankshaft a protrudes with its pin b into the lubricating oil guide chamber c. An oil guide ring d is connected between pin b and space c. This is stored tightly and flexibly in the walls of the oil supply space c by means of face seals, Simmeringen or similar soft packings e, e '. The oil supply ring has the oil inlet openings f of the shaft journal b opposite openings g for the admission of the lubricating oil and surrounds the journal with the smallest possible bearing clearance. It is Z. B. a bearing clearance of only 0.04 to 0.05 mm feasible if the oil feed ring is given a lining h made of white metal. A pin i secures the ring d against turning.

Das Schmieröl wird dem Raum c unter Druck zugeführt und strömt durch die Durchbrechungen g des Ölzuführungsringes d und die Eintrittsöffnungen f des umlaufenden Zapfens in dessen Hohlraum kein. Von dort aus gelangt das Öl, wie durch den Pfeil angedeutet, über weitere Hohlräume und Bohrungen der Kurbelwelle zu dem Kurbelzapfen na und von dort schließlich zu den dieselben umfassenden Pleuellagern.The lubricating oil is supplied to the space c under pressure and does not flow through the openings g of the oil supply ring d and the inlet openings f of the rotating journal into its cavity. From there, as indicated by the arrow, the oil passes through further cavities and bores in the crankshaft to the crank pin na and from there finally to the connecting rod bearings encompassing the same.
