Description
Befestigung derclägr von Kohlemühlen Zusatz zurrt ']Patent 653 80; Die Erfindung betrifft eine Verbesserung der Befestigung für Schläger von Kohlemühlen. Nach Patent 653807 ragt ein Bolzen in die Nut hinein, welche der den Schlagerarm aufnehmenden Nut benachbart ist, und ist dort mittels einer von außen lösbaren Befestigung ;gegen Verschieben gesichert. Die Erfindung stellt eine weitere Ausbildung der durch dieses Patent geschützten Erfindung dar: Sie besteht darin, däß die von außen lösbare Sicherung des Bolzens gegen Verschieben, die in der der Nut des zugehörigem Schlägers benachbarten Nut sitzt, als Widerhager für die Schläger dieser Nut ausgebildet ist, in das eine Stiftschraube ,eingeschraubt ist, deren Ende m eine Eindrehung des Befestigungsbolzens eingreift.Attachment of the coal mills addendum to '] Patent 653 80; The invention relates to an improvement in the attachment for coal mill beaters. According to patent 653807, a bolt protrudes into the groove, which is adjacent to the groove receiving the striker arm , and is secured there against displacement by means of an externally releasable fastening. The invention represents a further development of the invention protected by this patent: It consists in the fact that the externally releasable securing of the bolt against displacement, which sits in the groove adjacent to the groove of the associated club, is designed as an abutment for the club of this groove , into which a stud screw is screwed, the end of which engages a recess in the fastening bolt.
In der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform dargestellt.In the drawing, the subject matter of the invention is in one embodiment shown.
Abb. i zeigt einen Längsschnitt durch den Läufer der Schlägermühle, und Abb. z :gibt einen Querschnitt durch den Läufer wieder.Fig. I shows a longitudinal section through the rotor of the beater mill, and Fig. z: shows a cross-section through the rotor.
Auf dem Läufer i befinden sich die Scheiben a mit den dazwischenliegenden Nuten 3, In den Scheiben z sind eine Anzahl Löcher q, vorhanden, die zur Aufnahme der Befestigungsbolzen 9 für die Schläger d dienen. Nach dem Hauptpatent ragen die Bolzen 9 in die Nut hinein, welche der den Schlägerarm aufnehmenden Nut benachbart ist. Die Sicherung des Bolzens 9 erfolgt nun gemäß der Erfindung durch das als Widerlager ausgebildete Werkstück 14 und eine Stiftschraube 15, die in das Widerlager 14 eingeschraubt ist und mit ihrem Ende in eine Eindrehung 16 des Bolzens 9 eingreift. Das Ende der Schraube i5 kann hierbei entweder spitz oder in einem kurzen, dünnen Zapfen auslaufen. Zwischen dem Kopf der Schraube 15 und dem Widerlager 1q. befindet sich die Sicherungsscheibe 17. Die Sicherung des Befestigungsbolzens 9 durch eine Stiftschraube ist wesentlich besser als die in dem Ausführungsbeispiel des Hauptpatents behandelte Sicherung mittels eines Splintes. Der Ein- und Ausbau der Schläger wird durch die neue Sicherungseinrichtung erheblich beschleunigt, demi die Stiftschrauben lassen sich leicht einschrauben und wieder lösen. Dagegen ist das Einführen und Entfernen eines Splintes häufig sehr schwierig und langwierig.On the rotor i are the disks a with the intermediate ones Grooves 3, in the disks z there are a number of holes q, which are for receiving the fastening bolt 9 for the racket d serve. After the main patent, the Bolt 9 into the groove which is adjacent to the groove receiving the club arm is. The bolt 9 is now secured according to the invention by acting as an abutment formed workpiece 14 and a stud screw 15 which is screwed into the abutment 14 is and engages with its end in a recess 16 of the bolt 9. The end of Screw i5 can either be pointed or tapered into a short, thin pin. Between the head of the screw 15 and the abutment 1q. is the lock washer 17. Securing the fastening bolt 9 by means of a stud is essential better than the fuse treated in the embodiment of the main patent by means of a split pin. The installation and removal of the clubs is made possible by the new safety device significantly accelerated, as the stud bolts can be screwed in easily and solve again. In contrast, the insertion and removal of a split pin is common very difficult and tedious.
In Abb. ä kann man an dem strichpunktiert eingezeichneten Schläger 6',erken:nen, wie .sich die Schlägerarme beim Stillstand der Mühle gegen das Widerlager 14 -legen. Das Widerlager 14 stützt sich hierbei auf dem Läufer t ab.In Fig. Ä you can see the dash-dotted racket 6 ', recognize how the beater arms move against the abutment when the mill is at a standstill 14 - lay. The abutment 14 is supported here on the rotor t.
