Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine besondere Einrichtung an Ackerwalzenring-Naben, insbesondere für Untergrundwalzen, mit dem Zwecke, das Eindringen von Sand zwischen die Reibflächen zu verhüten.The invention relates to a special device on farm roller ring hubs, in particular for underground rollers, with the purpose of the penetration of sand between to prevent the friction surfaces.
Die üblichen Vorrichtungen zum Abdichten von Naben lassen sich entweder infolge Raummangels nicht anwenden oder begünstigen sogar, wie dies z. B. bei den bekannten, zwisehen die Naben bzw. im Nabeninnern angeordneten Dichtungsringen der Fall ist, den Aufenthalt von Sandteilchen zwischen den Reibungsflächen.The usual devices for sealing hubs can either be due to a lack of space do not apply or even favor, as z. B. with the known, zwisehen the hubs or sealing rings arranged in the hub interior is the case, the stay of sand particles between the Friction surfaces.
Die vorliegende, in der Zeichnung durch die Fig. ι und 2 dargestellte Erfindung beseitigt diesen Mangel ohne Zuhilfenahme von besonderen, die Konstruktion der Walze verteuernden Hilfsmitteln. An der Nabe η ist ein überstehender Rand ο vorgesehen, welcher die Stoßfläche p überragt (Fig. 2). Der Umfang des Randes ist dachförmig gestaltet, so daß der darauf fallende Sand von der Stoßfläche abgelenkt wird. Auch die unter dem Ringe bzw. Rande 0 liegende Oberfläche der Nabe η ist so mit Gefalle versehen, daß der Sand nicht an die Stoßstelle gleiten kann. Die Nabenenden haben zu diesem Zwecke die Form von abgestumpften Kegeln.The present invention, represented in the drawing by FIGS. 1 and 2, eliminates this deficiency without the aid of special aids which make the construction of the roller more expensive. A protruding edge ο is provided on the hub η , which protrudes beyond the abutment surface p (FIG. 2). The periphery of the edge is roof-shaped so that the sand falling on it is deflected from the impact surface. The surface of the hub η lying under the ring or edge 0 is also provided with a slope in such a way that the sand cannot slide onto the joint. The hub ends have the shape of truncated cones for this purpose.
Über der Stoßstelle kann auch ein Reifen / von satteldachförmigem Querschnitt gemäß Fig. ι gelegt sein.A tire / of gable roof-shaped cross-section according to Fig. ι be placed.
