Description

Abdichtung des Propellerwellenlagers an Außenbordmotoren. Die Erfindung betrifft eine Abdichtung des Propellerwellenlagers an Außenbordmotoren gegenüber dem Wasser, und zwar besonders von solchen Motoren, bei denen der Propellerwelle das Schmieröl unter Druck zugeführt wird. Gemäß der Erfindung wird mittels eines Deckels eine Dichtungsscheibe aus Leder oder anderem elastischen Material an ihrem äußeren Rande fest gegen das Lagergehäuse gepreßt und mit dem inneren Rande elastisch gegen einen Wellenbund gedrückt. Der Deckel greift hierbei über die Welle und ist am Rande mit Gewinde versehen, mit welchem er in das Gehäuse eingeschraubt ist. Im Innern besitzt der Deckel einen Hdhlraum, in dem eine Schraubenfeder mittels einer über die Welle geschobenen Buchse die Lederscheibe gegen den Wellenbund anpreßt und damit die Abdichtung des zu schmierenden Wellenlagers im Gehäuse nach dem Außenwasser hin vollendet. In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes. dargestellt.Sealing of the propeller shaft bearing on outboard motors. The invention relates to a seal for the propeller shaft bearing on outboard motors the water, especially from those engines where the propeller shaft the lubricating oil is supplied under pressure. According to the invention, by means of a Cover a sealing washer made of leather or other elastic material on their outer edge pressed firmly against the bearing housing and elastic with the inner edge pressed against a shaft collar. The cover engages over the shaft and is provided on the edge with a thread with which it is screwed into the housing. Inside the lid has a hollow space in which a helical spring means a sleeve pushed over the shaft presses the leather washer against the shaft collar and thus the sealing of the shaft bearing to be lubricated in the housing from the outside water completed. The drawing shows an exemplary embodiment of the subject matter of the invention. shown.

Abb. z ist ein senkrechter Schnitt durch den hinteren Teil des Lagergehäuses für die Propellerantriebswelle und Abb. a eine teilweise Stirnansicht des Dichtungsdeckels.Fig. Z is a vertical section through the rear of the bearing housing for the propeller drive shaft and Fig. a is a partial front view of the sealing cover.

a ist eine Dichtungsscheibe aus Leder oder einem anderen elastischen Material, welche von einem besonders geformten Deckel b festgehalten wird. Der Deckel b greift über die Antriebswelle c des Propellers und ist in eine Ausdrehung ihres Lagergehäuses g eingeschraubt.a is a sealing washer made of leather or some other elastic Material which is held in place by a specially shaped cover b. The lid b engages over the drive shaft c of the propeller and is in a recess of yours Bearing housing g screwed.

Die Dichtungsscheibe a wird hierbei von dem Deckel b nur an ihrem Rande gefaßt und festgehalten. Innerhalb des Deckels befindet sich eine Buchse f, welche von einer Schraubenfeder e gegen den Bund d der Welle gepreßt wird. Eine Verdrehung des Deckels b im Lagergehäuse g der Welle c wind durch; Sicherungsschrauben h verhindert. Der Deckel läßt sich durch einen passenden Schraubenschlüssel mit Zapfen, die in die Aussparungen i passen, in das Gehäuse g hinein oder aus diesem herausschrauben.The sealing washer a is gripped and held in place by the cover b only at its edge. Inside the cover there is a bushing f which is pressed by a helical spring e against the collar d of the shaft. A rotation of the cover b in the bearing housing g of the shaft c winds through; Locking screws h prevented. The cover can be screwed into or out of the housing g using a suitable wrench with pins that fit into the recesses i.
