Description

Antriebstrommel. Den Gegenstand vorliegender Erfindung bildet eine Antriebstrommel für Werkzeug-und andere Arbeitsmaschinen, deren Wesen darin besteht, daß -dieselbe aus einzelnen kalt gezogenen Schüssen zusammengesetzt ist, wobei der Boden jedes Schusses als Querversteifung der Trommel dient.Drive drum. The subject of the present invention is one Drive drum for machine tools and other working machines, the essence of which is that it is composed of individual cold-drawn shots, the The bottom of each shot serves as a transverse stiffener for the drum.

Bisher wurden die einzelnen Schüsse .der Antriebstrommel aus rechteckigen, zylindrisch aufgerollten Blechstücken hergestellt, die der Länge nach verlötet wurden. Die Längsnaht brachte den Nachteil mit sich, daß sie häufig Risse bekam, was umständliche und teure Instandsetzungsarbeiten erforderlich machte. In die einzelnen Schüsse waren ferner tellerförmige Böden zur Versteifung der ganzen Trommel eingelötet, deren Ausführung und Anbringung ebenfalls kostspielig und zeitraubend war.So far, the individual sections of the drive drum were made of rectangular, Cylindrical rolled pieces of sheet metal produced, which were soldered lengthwise. The longitudinal seam had the disadvantage that it often cracked, which was cumbersome and required expensive repairs. In the individual shots plate-shaped bottoms were also soldered in to stiffen the entire drum, which were also costly and time consuming to implement and install.

Nach dem neuen Verfahren werden diese Mängel vermieden und unter Herbeiführung der größtmöglichsten Widerstandsfähigkeit der Antriebstrommel eine verbilligte Herstellungsweise gewährleistet, indem der Boden mit jedem Schuß der Trommel zusammen kalt gezogen wird. Dabei wird der Schuß am Bodenende so verengt, daß der benachbarte Schuß Barübergezogen und dann in bekannter Weise mit dem ersten Schuß durch Vernieten oder Verlöten verbunden werden kann.According to the new method, these deficiencies are avoided and brought about the greatest possible resistance of the drive drum a cheaper production method ensured by cold pulling the bottom together with each shot of the drum will. The shot is narrowed at the bottom end so that the adjacent shot is pulled over and then connected in a known manner to the first shot by riveting or soldering can be.

In der beiliegenden Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt.In the accompanying drawing is an exemplary embodiment of the invention shown.

a ist einer der mit dem Boden b aus einem Stück kalt gezogenen Trommelschüsse, der bei e so verengt ist, daß der benachbarte Schuß f Barübergezogen werden kann, worauf beide Schüsse durch Vernieten oder Verlöten miteinander verbunden werden. Um das Widerstandsmoment des Bodens b möglichst groß zu machen und damit die Haltbarkeit der aus den einzelnen Schüssen zusainmengesetzten ganzen Trommel zu verbessern, ist jeder Boden bei c nach innen und bei d wieder nach außen ausgebuchtet.a is one of the barrel sections cold drawn from one piece with the bottom b , which is so narrowed at e that the adjacent section f can be pulled over, whereupon the two sections are connected to one another by riveting or soldering. In order to make the section modulus of the base b as large as possible and thus improve the durability of the entire drum assembled from the individual shots, each base is bulged inwards at c and outwards again at d.
