Druckschulter, auch Füllstück genannt, für Meißel von KohlenhobelPressure shoulder, also called filler piece, for chisels from coal planers
Die Neuerung betrifft eine Druckschulter, auch Füllstück ge nannt, für Meißel von Kohlenhobel, die in eine Tasche eingesetztThe innovation concerns a pressure shoulder, also called a filler piece, for chisels from coal planers inserted into a pocket
Meißel von Kohlenhobel wurden bisher in den Aufnahmetaschen des Kohlenhobels durch Druckschultern oder sogenannte Füllstücke gehalten, die ihrerseits durch Schwerspannstifte gesichert waren.Chisels from coal planers were previously in the receiving pockets of the coal planer by pressure shoulders or so-called filler pieces held, which in turn were secured by dowel pins.
Im Rahmen des Energieforschungsprogrammes der Bundesrepublik Deutschland wurden u.a. auch auf der Schachtanlage Rossenray am Niederrhein Versuche mit verschiedenen Kohlenmeißeln gefahren. Hierbei stellte sich heraus, daß ein Meißeltyp, und zwar ein Wendemeißel, der einen festen Siez in der Tasche aufwieß, die besten Ergebnisse brachte.As part of the energy research program of the Federal Republic of Germany, the Rossenray Tests carried out with various coal chisels on the Lower Rhine. It turned out that a chisel type, namely a Reversible chisel that had a firm Siez in the pocket gave the best results.

Aufgabe der Neuerung ist es daher, eine Druckschulter für Kohlenhobel-Meißel zu schaffen, die neben der leichten Lösbarkeit, dem Meißel in der Tasche einen festen Sitz ver schafft. The task of the innovation is therefore to create a pressure shoulder for coal planing chisels that, in addition to being easy to remove, the chisel in the pocket provides a secure fit.
Zur Erreichung dieses Zieles schlägt die Neuerung vor, daß die Druckschulter aus mehreren, gegeneinander verschieb baren Teilen besteht, die durch eine Schraube mit Mutter gegeneinander verspannt werden. Die Druckschulter besteht aus zwei gleichen Konussen und Backen.To achieve this goal, the innovation suggests that the pressure shoulder consists of several, mutually displaceable ble There are parts that are braced against each other by a screw with a nut. The pressure shoulder exists from two identical cones and jaws.
Der Vorteil der neuerungsgemäßen Druckschulter ist darin zu sehen, daß die spannbare Druckschulter Ungenauigkeiten in der Fertigung sowie natürlichen Verschleiß durch Abrieb aufhebt, in dem sie den Raum zwischen Meißel und Tasche immer voll ausfüllt. The advantage of the pressure shoulder according to the innovation is in it see that the tensionable pressure shoulder inaccuracies in the Manufacturing as well as natural wear and tear due to abrasion, in which it always completely fills the space between the chisel and the pocket.
In der Zeichnung ist der Gegenstand der Neuerung in einem Ausführungsbeispiel dargestellt.In the drawing, the subject of the innovation is shown in one embodiment.
Die Figur zeigt einen Längsschnitt durch den Meißel mit Tasche und Druckschulter.The figure shows a longitudinal section through the chisel with a pocket and pressure shoulder.
Der Meißel 17, der sich in der Tasche l8 befindet, ist als sogenannter Wendemeißel mit drei Schneiden dargestellt. Gehalten wird der Meißel durch seitlich in der Tasche angebrachte Nocken 19, die die Verdichtungen 2o, des Meißels untergreifen.The chisel 17, which is located in the pocket 18, is shown as a so-called reversible chisel with three cutting edges. Held the chisel is secured by cams 19 attached to the side in the pocket, which compress the chisel 2o reach under.
Um ein Herausschieben des Meißels 17 aus der Tasche l8 zu verhindern, ist hinter dem Meißel eine Druckschulter Io eingesetzt, die sich, an der Taschenrückwand l8* und dem Meißel 17 abstützt. Die spannbare Druckschulter Io, auch Füllstück genannt, besteht aus zwei gleichen Konussen 11 und 12 und Backen 13 und lk, sowie einer Schraube 15 mit Vierkantmutter l6.In order to prevent the chisel 17 from being pushed out of the pocket 18, a pressure shoulder Io is inserted behind the chisel, which is supported on the rear wall of the pocket 18 * and the chisel 17. The tensionable pressure shoulder Io, also called a filler piece, consists of two identical cones 11 and 12 and jaws 13 and lk, as well as a screw 15 with square nut l6.
Durch Drehen der Schraube 15 nähern sich die Konusse 11 und aufeinander zu, wobei die Backen 13 und 1^t gegen MeißelBy turning the screw 15, the cones 11 and approach one another, with the jaws 13 and 1 ^ t against the chisel

und Tasche l8* gedruckt, d.h. verspannt werden.and pocket 18 * printed, i.e. clamped.
Die Schraube ist als Innensechskantschraube, und die Mutter als Vierkantmutter dargestellt.The screw is shown as a hexagon socket screw and the nut as a square nut.
