Description

Die Erfindung. bezieht sich auf eine mehrzylindrige Zweitakt-Brennkraftmaschine (vorzugsweise eine solche mit Vergaser) mit Kurbelwellenwälzmittellager und gegenseitiger Abdichtung der Kurbelkammern mittels Spreizring-Dichtung.The invention. relates to a multi-cylinder two-stroke internal combustion engine (preferably one with a carburetor) with crankshaft roller bearings and mutual Sealing of the crank chambers by means of an expanding ring seal.

Die Anordnung von Spreizringen zur gegenseitigen Abdichtung benachbarter Kurbelkammern .ist bekannt. Durch die Erfindung wird eine einfache Anwendung dieser Spreizring-Abdichtung für Kurbelwellenwälzmittellager geschaffen; die Erfindang besteht darin, daß mindestens einer der Wälzlagerringe eine seitliche Verbreiterung besitzt, die als Anlage für den Spreizring dient.The arrangement of expansion rings for mutual sealing of neighboring Crank chambers. Is known. The invention makes it easy to use Expanding ring seal created for crankshaft rolling center bearings; the invention consists in that at least one of the rolling bearing rings has a lateral widening owns, which serves as an attachment for the expansion ring.

Die Verbindung des Wälzlagers mit der Spreizring-Abdichtung bietet nicht nur Vorteile beim Bau und bei der Montage, sie wird auch durch die Maschinenwärme nicht so stark beeinflußt wie die getrennte Ausführung einer Dichtung und eines Lagers. Eine über die Kurbelwellenwälzmittel-Lagerung und die Abdichtung der Kurbelkammern hinausgehende Anwendung der vorgeschlagenen Wälzlagerringausbildung ist nicht Gegenstand der Erfindung.The connection of the rolling bearing with the expanding ring seal offers not only advantages in construction and assembly, it is also due to the machine heat not affected as much as running a seal and one separately Camp. One over the crankshaft rolling element bearings and the sealing of the crank chambers Going beyond application of the proposed rolling bearing ring training is not the subject the invention.

Weitere Ausbildungen der Erfindung lassen sich aus der nachfolgenden Beschreibung der Zeichnungen ersehen, welche drei Ausführungsbeispiele der Erfindung zeigen.Further developments of the invention can be found in the following Description of the drawings, which three embodiments of the invention demonstrate.

Gemäß Abb. I ist .der äußere Ring I des Kurbelwellenwälzmittellagers verbreitert und trägt die Dichtgleitfläche 2 der beiden Spreizringe 3. Diese bilden mit einer Nut 4 eines inneren Ringes 5 eine Art Labyrinthdichtung. Die Spreizringe 3 sind nach Art von Kolbenringen hergestellt und spreizen sich nach außen gegen die Dichtfläche 2 des verbreiterten äußeren Wälzlagerringes I. Gemäß Abb. 2 ist auch der innere Wälzlagerring 6 verbreitert und trägt die Nut 4 für die Spreizringe 3. Der äußere Wälzlagerring I ist bei 7 verstärkt.According to Fig. I, the outer ring I of the crankshaft rolling center bearing is widened and carries the sealing sliding surface 2 of the two expanding rings 3. These form with a groove 4 of an inner ring 5, a kind of labyrinth seal. The expanding rings 3 are made in the manner of piston rings and spread against the outside the sealing surface 2 of the widened outer rolling bearing ring I. According to Fig. 2 is the inner roller bearing ring 6 is also widened and carries the groove 4 for the expansion rings 3. The outer roller bearing ring I is reinforced at 7.

Nach Abb. 3 ist der innere Wälzlagerring bei ä verstärkt. Bei dieser Ausführung spannen sich die Spreizringe gegen den inneren Wälzlagerring, während sie bei der Ausführung nach Abb. I und 2 sich gegen den äußeren Wälzlagerring spreizen.According to Fig. 3, the inner roller bearing ring is reinforced at ä. At this Execution, the expansion rings tighten against the inner roller bearing ring, while in the design according to Fig. I and 2, they spread against the outer rolling bearing ring.

Selbstverständlich können die Nuten auch in dem verstärkten Teil des verbreiterten Wälzlagerringes angeordnet sein. Diese Anordnung würde sich z. B. dann ergeben, wenn der innere. Wälzlagerring und der Ring 5 nach Abb. I erfindungsgemäß aus einem Stück bestehen würden.Of course, the grooves can also be in the reinforced part of the widened rolling bearing ring be arranged. This arrangement would z. B. then surrender when the inner. Rolling bearing ring and the ring 5 according to Fig. I according to the invention would consist of one piece.
