Description

Kurbelgehäuse für Zweitaktmotoren mit Abdichtung zwischen Kurbelscheiben und Gehäuse. Den Gegenstand der Erfindung bildet eine an Kurbelgehäusen von Zweitaktmotoren angeordnete Einrichtung zur Abdichtung des Kurbelraumes gegen die Außenluft während des Betriebes. Erfindungsgemäß ist die Kurbelscheibe b mit einer nach außen kegelförmig ansteigenden Mantelfläche versehen, welche mit ihrem in der Abb. i mit d bezeichneten größten Umfange so nahe an die Innenwand des Gehäuses e tritt, daß infolge Schleuderwirkung des im . Kurbelgehäuse befindlichen Schmiermittels bei d eine Abdichtung entsteht, sobald der Motor sich im Betrieb befindet. Man kann, wie die Abb. z zeigt, durch Aussparung einer Ringnut e, innerhalb welcher ein an der Kurbelscheibe befindlicher Laufring f mit wenig Spiel umläuft, die Abdichtungsflächen wirksam vergrößern, um auch bei geringer Umdrehungszahl des Motors genügende Abdichtung zu erzielen.Crankcase for two-stroke engines with a seal between crank discs and housing. The subject matter of the invention is a crankcase for two-stroke engines arranged device for sealing the crankcase against the outside air during of the company. According to the invention, the crank disk b is conical with one outward provided rising surface area, which is designated with its in Fig. i with d largest extent so close to the inner wall of the housing e occurs that as a result of the centrifugal effect of the in. Crankcase lubricant at d a seal is created, as soon as the engine is running. One can, as Fig. Z shows, through Recess of an annular groove e, within which a located on the crank disk Running ring f revolves with little play to effectively enlarge the sealing surfaces to achieve sufficient sealing even at low engine speeds.
