Zusatz zum Patente 186314 vom 6. April 1905.Addendum to patent 186314 from April 6, 1905.
Patentiert im Deutschen Reiche vom 1. Februar 1906 ab. Längste Dauer: 5.April 1920. Patented in the German Empire on February 1, 1906 . Longest duration: April 5, 1920.
Gegenstand der Erfindung ist eine weitere Ausbildung der durch Patent 186314 geschützten Antriebsvorrichtung für das Rührwerk in mechanischen Röstöfen, bei welcher die lotrechte, hohle Rührwelle ihre Drehung durch ein auf ihr oberes Ende wirkendes Getriebe erhält, das der infolge der im Ofen herrschenden hohen Temperatur auftretenden Längenausdehnung der Welle Rechnung trägt.The subject of the invention is a further embodiment of that protected by patent 186314 Drive device for the agitator in mechanical roasting ovens, in which the vertical, hollow agitator shaft rotates by a gear acting on its upper end, which is obtained as a result of the in the furnace The high temperature that occurs takes account of the linear expansion of the shaft.
ίο _, Während nun bei den Ausführungen des t|auptpatentes die erstrebte Wirkung durch ein eine achsiale Bewegung des auf der Rührwelle befestigten getriebenen Teiles gestattendes Getriebe bewirkt wird, ist nach vorliegender Erfindung das Getriebe unverrückbar auf der Ofendecke gelagert, und es ist dafür zur Ermöglichung der Längenausdehnung der Rührwelle diese durch Feder und Nut oder andere ähnliche Mitnehmer so mit dem unmittelbar auf sie einwirkenden Getriebeteil verbunden, daß die Drehung des letzteren zwar auf die Rührwelle übertragen wird, diese sich aber dem Getriebe gegenüber in achsialer Richtung bewegen kann. Diese Neuerung hat gegenüber den Ausführungen des Hauptpatentes den wesentlichen Vorteil, daß das dort vorgesehene Stirnräderpaar vermieden bezw. das Schneckengetriebe die gebräuchliche Gestalt erhalten kann.ίο _, While now with the remarks of the t | auptpatentes the desired effect through an axial movement of the on the Stirring shaft attached driven part permitting gear is effected is after In the present invention, the gearbox is immovably mounted on the furnace roof, and it is to enable the length expansion of the agitator shaft by means of a spring and groove or other similar drivers with the one acting directly on them Gear part connected that the rotation of the latter is indeed transmitted to the agitator shaft is, but this can move in the axial direction opposite the transmission. These The innovation has the main advantage over the main patent, that the pair of spur gears provided there avoided respectively. the worm gear is the usual one Can get shape.
Auf der Zeichnung ist der Erfindungsgegenstand in zwei Ausführungsbeispielen veranschaulicht. Es zeigt Fig. 1 die erste Ausführung in lotrechtem, mittlerem Schnitt und Fig. 2 in Draufsicht. Die Fig. 3 und 4 zeigen entsprechende Darstellungen der zweiten Ausführung.The subject of the invention is shown in two exemplary embodiments in the drawing illustrated. 1 shows the first embodiment in a vertical, central section and FIG. 2 in plan view. 3 and 4 show corresponding representations of the second Execution.
Bei dem ersten Ausführungsbeispiele nach Fig. ι und 2 ist 1 die Rührwelle, welche durch ein Schneckengetriebe angetrieben wird. Das Schneckenrad 2 ist in einem auf der Ofendecke befestigten Gehäuse 3 drehbar, aber gegen achsiale Bewegung gesichert, konzentrisch zur Rührwelle I gelagert und steht mit der Schnecke 4 in Eingriff, deren Welle 5 ebenfalls im Gehäuse 3 gelagert ist und beispielsweise durch Vermittelung eines Riementriebes in Drehung versetzt wird. Die unter entsprechender Abdichtung durch den Boden des Gehäuses 3 hindurchreichende Rührwelle ist an ihrem oberen Ende mit einem nach außen und abwärts gerichteten, glockenförmigen Ansätze 6 versehen, der in die entsprechend weit ausgebohrte Nabe des Schneckenrades eingreift und mit achsial verlaufenden Nuten 7 ausgerüstet, in die in der Nabenbohrung angebrachten Federn oder Flachkeile 8 eingreifen. Infolge dieser Einrichtung wird die Drehung des Schneckenrades 2 durch Vermittlung der Keile auf die Rührwelle übertragen, wobei diese sich aber ungehindert in dem Schneckenrade achsial verschieben, also ihrer Längenausdehnung folgen kann.In the first exemplary embodiment according to FIGS. 1 and 2, 1 is the agitator shaft, which is driven by a worm gear. The worm wheel 2 is in one on the Housing 3 attached to the furnace roof can be rotated, but secured against axial movement, concentrically mounted to the agitator shaft I and is in engagement with the screw 4, the shaft 5 is also stored in the housing 3 and, for example, by means of a belt drive is set in rotation. The under appropriate sealing through the floor of the housing 3 reaching through agitator shaft is at its upper end with a outwardly and downwardly directed, bell-shaped lugs 6 provided, which in the corresponding The hub of the worm wheel, which is bored out, engages and is equipped with axially extending grooves 7, into which in springs or flat wedges 8 attached to the hub bore. As a result of this establishment the rotation of the worm wheel 2 is transmitted to the agitator shaft by means of the wedges, but this shifts unhindered move axially in the worm wheel, that is, their linear expansion can follow.
Die zweite Ausführung unterscheidet sich von der beschriebenen nur durch die Art der Verbindung zwischen Rührwelle 1 undThe second version differs from the one described only in the type the connection between agitator shaft 1 and

Schneckenrad 2. In der Nabe des letzteren sind nämlich ein oder mehrere Augen 9 angegossen, in welchen aufrecht stehende Mitnehmerbolzen 10 gehalten werden, welche mit ihrem oberen Ende in Löcher 11 entsprechend an der Rührwelle vorgesehener Ohren 12 eingreifen. Diese Mitnehmerbolzen 10 übertragen ebenfalls wieder die Drehung des Schneckenrades 2 auf die Rührwelie 1, ohne deren Längenausdehnung zu behindern.Worm wheel 2. In the hub of the latter one or more eyes 9 are cast on, in which upright driving pins 10 are held, which with their upper end engage in holes 11 corresponding to ears 12 provided on the agitator shaft. These driving pins 10 also transmit the rotation of the Worm wheel 2 on the agitator shaft 1, without hindering its linear expansion.
