Description
Ackerwalze.
Die vorliegende Erfindung betrifft eine Ackerwalze, bei welcher sich mindestens eine Trommel mitbels Kugellagern auf einer im Gestell befestigten, festen Achse dreht. Diese Achse kann durchgehend oder unterbrochen, zum Beispiel durch zwei getrennte Achszapfen gebildet sein. Für den Fall, dabe au einerdurchgehendenAchsemehrere Trom meln nebeneinander vorgesehen sind, sind zweckmϯig an jedem Trommelende Kugellager vorgesehen.
Die Zeichnung zeigt ein Ausführungsbei- spiel des Erfindungsgegenstandes mit einem der Trommellager im Schnitt.
1 ist die Trommel und 2 das Fahrgestell.
Auf jeder Stirnseite der Trommel ist eine runde Blechkapsel 3 aufgeschraubt, welche einen eingepressten Holzring 4 trägt. In der Ringöffnung ist ein Kugellager 5 angeord- net, dessen innerer Laufring auf einem im Fahrgestell gelagertenundvon einerSchraube 7 festgestellten Zapfen 6 aufgezogen ist. Der Holzring 4 besitzt einen Absatz 4', gegen welchen das Kugellager anliegt und in weleher Stellung es durch den Zapfen 6 gehalten wird. Der Holzring ist breiter als das Kugellager, so dass zwischen diesem, und der Trommel ein genüNgend gro¯er Zwischenraum besteht, der eine Reibung dieser Teile verhin dert. Der durch den Absatz 4''bedingte Zwischenraum zwischen Kugellager und Blechkapsel wird mit Vaseline gefüllt.
Ein Filzring 8 verhindert das Austreten des Schmiermittels aus der Blechkapsel, sowie das Eindringen von Staub und Unreinigkeiten in dieselbe.
Die dargestellte und beschriebene Acker- walze lÏuft gegenüber bekannten ähnlichen Maschinen zufolge des das Kugellager tra genden Holzringes, der als Schalldämpfung wirkt, Ïu¯erst ruhig und lärmfrei. Die schalldÏmpfende Zwischenlage konnte auch aus Gummi oder sonstigen schalldämpfenden Mitteln hergestellt sein. Statt der zwei an den Stirnseiten vorgesehenen Achszapfen könnte auch eine durchgehende Achse fest im Fahrgestell angeordnet sein.
Farm roller.
The present invention relates to a field roller in which at least one drum rotates by means of ball bearings on a fixed axle fixed in the frame. This axis can be continuous or interrupted, for example by two separate axle journals. In the event that several drums are provided next to one another on a continuous axle, ball bearings are expediently provided at each end of the drum.
The drawing shows an exemplary embodiment of the subject matter of the invention with one of the drum bearings in section.
1 is the drum and 2 is the chassis.
A round sheet metal capsule 3, which carries a pressed-in wooden ring 4, is screwed onto each end face of the drum. A ball bearing 5 is arranged in the ring opening, the inner race of which is pulled onto a pin 6 mounted in the chassis and fixed by a screw 7. The wooden ring 4 has a shoulder 4 'against which the ball bearing rests and in which position it is held by the pin 6. The wooden ring is wider than the ball bearing, so that there is a sufficiently large space between it and the drum to prevent friction between these parts. The space between the ball bearing and sheet metal capsule caused by paragraph 4 ″ is filled with Vaseline.
A felt ring 8 prevents the lubricant from escaping from the sheet metal capsule, as well as the penetration of dust and impurities into the same.
Compared to known similar machines, the illustrated and described field roller runs extremely quietly and free of noise due to the wooden ring carrying the ball bearing, which acts as a soundproofing device. The sound-absorbing intermediate layer could also be made of rubber or other sound-absorbing means. Instead of the two axle journals provided on the end faces, a continuous axle could also be fixedly arranged in the chassis.
