Description

Es ist eine bekannte Erfahrungsregel, daß alle bisher angewendeten Konstruktionen von in der Querrichtung geteilten Laufringen für Drehrohröfen zur Wärmebehandlung von Gut, Trockentrommeln od. dgl. bereits nach verhältnismäßig kurzer Zeit zum sogenannten »Kauen« neigen. Das Problem der vorliegenden Erfindung .besteht demzufolge darin, dieses Kauen zu verhindern, d. h. die Schläge, die durch nicht genaues Aneinanderpassen der Laufflächen der Scheibenteile in der Umfangsrichtung entstehen, herabzumindern, bzw. ganz zu vermeiden.It is a well-known rule of experience that all have been applied so far Constructions of races split in the transverse direction for rotary kilns for Heat treatment of goods, drying drums or the like after a relatively short time Tend to so-called "chew" at the time. The problem with the present invention exists consequently, in preventing this chewing, i.e. H. the blows that don't go through precise matching of the running surfaces of the disc parts in the circumferential direction arise, to diminish, or to avoid entirely.

Es hat in der Praxis nicht an Versuchen und Vorschlägen gefehlt, die durch diese Bewegungen ausgelösten erheblichen Nachteile zu beseitigen. So ist beispielsweise von Riemenscheiben her bekannt, das Rad in einer senkrechten Ebene zur Achse zu unterteilen und die so entstehenden Ringscheiben dann nochmals wieder quer zu teilen. Auf diese Weise können die Querfugen gegeneinander versetzt werden.In practice there has been no lack of attempts and suggestions that to eliminate the considerable disadvantages caused by these movements. So is for example known from pulleys, the wheel in a plane perpendicular to the axis subdivide and then divide the resulting ring disks crosswise again. In this way, the transverse joints can be offset against each other.

Ebenso ist bei zweiteiligen hölzernen Riemenscheiben die Anordnung von Nut und Feder zur Sicherung der Lage der Radscheibenteile gegeneinander nicht mehr neu.The arrangement is the same for two-part wooden pulleys of tongue and groove to secure the position of the wheel disc parts against each other more new.

Gegenüber diesen Ausführungen besteht das Merkmal vorliegender Erfindung in der Vereinigung und in dem Zusammenwirken dreier an sich bekannter Maßnahmen, -und .zwar soll a) der Laufring in senkrechten Ebenen zur Achse in zwei oder mehr Ringscheiben und jede der Scheiben weiterhin quer unterteilt sein, b) jede Ringscheibe in ihrer Lage zur benachbarten Scheibe durch Vor- und Rücksprünge oder Feder und Nut gesichert sein, c) jede Querfuge der einen Scheibe zu der Querfuge der Nachbarscheibe versetzt sein.Compared to these statements, there is the feature of the present invention in the union and in the interaction of three known measures, -und .zwar should a) the raceway in planes perpendicular to the axis in two or more Ring disks and each of the disks continue to be divided transversely, b) each ring disk in their position to the adjacent disc by projections and recesses or springs and Groove be secured, c) each transverse joint of one disc to the transverse joint of the neighboring disc be offset.

Dabei kann die an der Ringscheibe vorgesehene Feder als durchgehende Leiste ausgebildet sein, die in eine entsprechende Vertiefung der benachbarten Scheibe eingreift. Die Leiste selbst kann auch aus einzelnen Ringstücken bestehen.The spring provided on the annular disk can be used as a continuous spring Be formed bar that in a corresponding recess of the adjacent disc intervenes. The bar itself can also consist of individual ring pieces.

Bei dieser erfindungsgemäßen Ausbildung des Laufringes ist es besonders vorteilhaft, daß eine Auswechselung erfolgen kann, ohne ein Auseinandernieten der Trommel vornehmen zu müssen. Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes. Es zeigt Abb. i den Ring im Grundriß, Abb. z einen Querschnitt und Abb. 3 und 4 Querschnitte in veränderter Ausführungsform.It is special in this embodiment of the raceway according to the invention advantageous that a replacement can be made without riveting the To have to make drum. The drawing illustrates an embodiment of the subject matter of the invention. Fig. I shows the ring in plan, Fig. Z shows a cross-section and Figs. 3 and 4 cross-sections in a modified embodiment.

Der Laufring ist in senkrechten Ebenen zur Achse in zwei oder mehrere Scheiben a und b unterteilt, die in beliebiger Weise durch Schrauben oder Niete c zusammengehalten werden. Zur weiteren Sicherung und zur Vermeidung irgendwelcher Bewegung der Ringscheiben gegeneinander ist in der einen Ringscheibe b ein in Abb. z dargestellter Vorsprung d vorgesehen, der in eine entsprechende Vertiefung.der anderen Scheibe a eingreift.The raceway is in planes perpendicular to the axis in two or more Washers a and b divided in any way by screws or rivets c to be held together. For further security and to avoid any Movement of the annular disks against each other is evident in one of the annular disks b a in Fig. z projection d shown is provided, which is in a corresponding recess.der engages other disk a.

Abb. 3 " zeigt drei Ringscheiben, die mit Nuten und Federn gegeneinander gesichert sind; Abb. 4 zeigt zwei Ringscheiben a, b mit Nuten, in welche als Feder eine Leiste e eingelegt ist.Fig. 3 "shows three ring disks which are secured against one another with grooves and tongues; Fig. 4 shows two ring disks a, b with grooves in which a bar e is inserted as a tongue.

Diese Leiste e kann als geschlossener Kreis ausgebildet sein, sie kann aber auch aus mehreren einzelnen Ringteilen g bestehen.This bar e can be designed as a closed circle, they but can also consist of several individual ring parts g.
