Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Drehrohrofen haben bekanntlich, die Neigung, sich während der Drehung achsial zu bewegen. Man macht deshalb die Stützrollen, die paarweise die Drehtrommel unterstützen, mit ihren Achsen winklig zur Ofenachse verstellbar und bewirkt durch schräge Stellung •der Rollenachsen eine schraubenförmige Hin- und Herbewegung der Trommel in dem Maße, daß der Neigung der Trommel, zu wandern,It is well known that rotary kilns have the tendency move axially during rotation. You therefore make the support rollers that support the rotating drum in pairs, adjustable with their axes at an angle to the furnace axis and caused by inclined position • a helical reciprocating motion of the drum on the roller axles to the extent that that the drum's tendency to wander,

ίο entgegengewirkt wird und praktisch eine Achsialbewegung der Drehtrommel überhaupt nicht ',". stattfindet. Bei den bekannten Lagerungen dieser Art geschieht die Verstellung der Rollenachsen in einer wagerechten Ebene, d. h.ίο is counteracted and a substantially axial movement of the rotating drum does not '' takes place.. In the known bearings of this type the adjustment of the roller shafts occurs in a dare right level, ie

die Rollenlager liegen auf wagerechten Unterlagen. Diese Anordnungsweise führt zu Kantenpressungen, weil die wagerechte Unterlagsebene mit den auftretenden Kraftrichtungen in keinem inneren Zusammenhang steht.the roller bearings lie on horizontal supports. This arrangement leads to edge pressure, because the horizontal support level with the occurring directions of force has no intrinsic connection.

In der Patentschrift 212274 ist eine Stützrollcnanordnung beschrieben, die die Kantenpressung dadurch vermeidet, daß jede Stützrolle in einer Schwinge gelagert ist und sich durch den Druck der Drehtrommel selbst ein-In patent 212274 there is a support roller assembly described, which avoids the edge pressure in that each support roller is mounted in a rocker and itself by the pressure of the rotating drum itself

»5 stellen kann.»5 can put.

Die Erfindung beseitigt nun jede Kantenpressung ohne Anwendung einer Schwinge einfach dadurch, daß die Verstellung der Laufrollen um die Stützlinic als Achse erfolgt.The invention now simply eliminates any edge pressure without using a rocker in that the adjustment of the rollers takes place around the support line as an axis.

Die Erfindung besteht also im wesentlichen darin, daß die Ebene, in welcher die Laufrollenachse verdreht wird, senkrecht zur Stützlinie liegt. Dadurch wird der bisher fehlende innere Zusammenhang der Stützrollenebene mit der auftretenden Kraftrichtung .hergestellt.The invention consists essentially in the fact that the plane in which the roller axis is rotated, is perpendicular to the support line. This eliminates the previously missing internal relationship between the support roller level with the direction of force occurring.

Auf der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise dargestellt, und zwar istIn the drawing, the invention is shown in one embodiment, for example, and although is

Fig. ι eine Seitenansicht, und ,40Fig. Ι a side view, and, 40

Fig. 2 ein Grundriß.Fig. 2 is a plan view.

Wie Fig. ι zeigt, ist im Gegensatz zu den bekannten Konstruktionen die Stützlinie α der Drehtrommel 1 zvir Achse gemacht, um die die Laufrollen 2 beim Verstellen gemäß Fig. 2 gedreht werden. Demgemäß steht die Stützlinie α senkrecht auf der Ebene b, in der die Verdrehung der Laufrollenachscn stattfindet. Eine Kantenpressung kann bei dieser Anordnungsweise nicht auftreten, vielmehr wird jede Rolle den Druck in der Mitte erhalten. As Fig. Ι shows, in contrast to the known constructions, the support line α of the rotary drum 1 is made about the axis around which the rollers 2 are rotated when adjusting according to FIG. Accordingly, the support line α is perpendicular to the plane b in which the rotation of the Laufrolleachscn takes place. Edge pressure cannot occur with this type of arrangement, rather each roller will receive the pressure in the middle.
