Description

Die Erfindung betrifft eine Vorrichtung zum Abdichten der Spalte in einem Wälzlager, das zur Lagerung einer Kurbelwelle in dem Motorblock einer Zweitakt-Brennkraftmaschine mit Kurbelkammerpumpe dient, wobei zum Abdichten feststehende Metallringe dienen, die gleitend an dem sich drehenden Wälzkörperlaufring des Wälzlagers anliegen.The invention relates to a device for sealing the gaps in a roller bearing that supports a crankshaft in the engine block of a two-stroke internal combustion engine is used with a crank chamber pump, whereby fixed metal rings are used for sealing, which slide against the rotating rolling element raceway of the rolling bearing.

Es ist bekannt, flache, im Bereich des sich drehenden Wälzkörperlaufringes des Wälzlagers gegen diesen Laufring abgewinkelte und an diesem anliegende Metallringe zum Abdichten zu verwenden. Diese nach außen radial auslaufenden Metallringe werden mit dem Lagerkörper verschraubt oder durch Anschlagringe in ihrer Lage gesichert. Die axial gerichteten Verschraubungen beanspruchen aber in Verbindung mit Klemmscheiben unerwünscht viel Raum in Richtung der Kurbelwelle, also Raum, der sehr wertvoll ist. Der Konstrukteur muß darauf bedacht sein, Brennkraftmaschinen eine möglichst geringe Baulänge zu verleihen. -Aus diesem Grund wirkt sich erfindungsgemäß die Maßnahme vorteilhaft aus, erstens den bzw. die Lagerkörper, in denen die feststehenden Wälzkörperlaufringe ruhen, nicht oder nicht wesentlich breiter als diese Wälzkörperlaufringe auszuführen und zweitens die schalenförmig ausgebauchten Metallringe in konzentrisch zum Wälzlager verlaufende Nuten der Lagerkörper einzulassen. Die Erfindung ist stets und ausschließlich dann vollendet, wenn beide der genannten Merkmale verwirklicht sind. Zweckmäßig ist es, die Nuten. unter einem Winkel von So bis 45° zur Kurbelwellenachse in den Lagerkörper einzustechen. In diesem Fall braucht dann die Breite der Lagerkörper nicht größer zu sein als die Breite des Wälzlagers. In der Zeichnung ist ein Ausführungsbeispiel der neuen Lagerung dargestellt. Der Kurbelwellenzapfen Ia der Kurbelwelle mit den Wangen Ib und den Pleuelzapfen Ic ruht in dem Wälzlager, dessen Hauptteile der sich drehende Wälzkörperlaufring 2 und der im Lagerkörper 3, 4 feststehend Wälzkörperlaufring 5 sind. Unter einem Winkel von 75° zur Kurbelwellenachse sind die Nuten 3a eingestochen, in die die schalenförmig geformten Metallringe 6 eingelegt sind. Die Metallringe sind nach dem Zusammenbau der Teile 3, 4 des Lager körpers so vorgespannt, daß die Flansche 6a dichtend an dem Wälzkörperlaufring 2 anliegen.It is known, flat, in the area of the rotating rolling element raceway of the roller bearing angled against this raceway and resting against this metal rings to use for sealing. These are metal rings tapering outwards radially screwed to the bearing body or secured in their position by stop rings. The axially directed screw connections, however, are demanding in connection with clamping disks undesirably a lot of space in the direction of the crankshaft, so space that is very valuable is. The designer must be careful, internal combustion engines as possible to lend a short overall length. For this reason, the invention affects the Measure advantageous, firstly the bearing body or bodies in which the stationary Rolling element races rest, not or not significantly wider than these rolling element races and second, the bowl-shaped bulging metal rings in concentric to allow grooves of the bearing body running towards the roller bearing. The invention is always and only completed when both of the features mentioned are achieved are. It is useful to use the grooves. at an angle of So to 45 ° to the crankshaft axis pierce the bearing body. In this case, the width of the bearing body then needs not to be larger than the width of the rolling bearing. In the drawing is an embodiment the new storage shown. The crankshaft journal Ia of the crankshaft with the Cheeks Ib and the connecting rod Ic rests in the roller bearing, the main parts of which are rotating rolling element raceway 2 and the rolling element raceway stationary in the bearing body 3, 4 5 are. The grooves 3a are cut at an angle of 75 ° to the crankshaft axis, in which the shell-shaped metal rings 6 are inserted. The metal rings are biased after the assembly of the parts 3, 4 of the bearing body that the Flanges 6a bear against the rolling element raceway 2 in a sealing manner.
