EMI1.1
grosser Drehmomente von einer Antriebsspindel auf Werkzeuge, wie Gewinde- und Lochbolirer (1. dgl.
Die Erfindung betrifft eine Einrichtung, um die zwischen die Antrieb : ; spindel und die eigentliche Werkzeugeinspanvorrichtung eingeschaltete bekannte Reibscheibenkupplung auf ein vorbestimmtes Drehmoment genau einzustellen. bei dessen Überschreiten die Kupplung gleitet, so dass ein Brechen des Werkzeuges durch eine übermässige Drehbeanspruchung verhindert wird.
In der Zeichnung ist eines Ausführungsform einer Einspannvorrichtung mit Einstell-

beispielsweise wiedergegeben.
Die Antriebsspindel 1 endet in einen Flansch : 2. Auf diesem liegt eine ringförmige Reibscheibe 3 aus elastischen Werkstoff. wie z. B. Vulkanfiber, und zwischen dem Flansch

mutter 8 aufgeschraubt, in deren Gewinde 11 ein gekordelter Stellring 12 eingeschraubt ist.
Dieser endet in eine Kegelfläche 13, die sich gegen die Kugeln 14 anlegt.
Wird der Stellring 12 ans der in der linken Hälfte der Zeichnung ersichtlichen Stellung in das Gewinde 11 eingeschraubt, so drängt er durch die Kegelfläche 13 die Kugeln 14 radial nach aussen, vobei durch den Ring 5 der Flaiisch 2 gegen das Futter 7 gedruckt wird (rechte Hälfte der Zeichnung). Der hiebei erzeugte Druck in der Reibscheibenkupplung hängt lediglich von der mehr oder weniger tiefen Einstellung der Kegelfläche 13 ab. Durch die Zwischenschaltung der Kugeln 14 ist der Druck zum Einstellen der Kuppelung ein ganz geringer, und es kann die Einstellung mittels des Hinges 12 von Hand genau ausgeführt werden. Die Einstellvorrichtung kann bei Kupplungen an Werkzeugmaschinen verschiedenster Art sowie auch an Antriebsvorriechtungen, wie z. B. Vorgelegen.
Anwendung finden.

EMI1.1
large torques from a drive spindle to tools, such as thread and hole bolts (1st.
The invention relates to a device to between the drive:; Spindle and the actual tool clamping device switched on known friction disc clutch to set exactly to a predetermined torque. if this is exceeded, the coupling slides so that the tool is prevented from breaking due to excessive torsional stress.
In the drawing is an embodiment of a clamping device with adjustment

for example reproduced.
The drive spindle 1 ends in a flange: 2. An annular friction disk 3 made of elastic material lies on this. such as B. vulcanized fiber, and between the flange
EMI1.3
screwed nut 8, into the thread 11 of which a corded adjusting ring 12 is screwed.
This ends in a conical surface 13 which rests against the balls 14.
If the adjusting ring 12 is screwed into the thread 11 in the position shown in the left half of the drawing, it pushes the balls 14 radially outwards through the conical surface 13, whereby the ring 5 presses the flaiisch 2 against the chuck 7 (right Half of the drawing). The pressure generated in the friction disk clutch depends only on the more or less deep setting of the conical surface 13. The interposition of the balls 14 means that the pressure for setting the coupling is very low, and the setting can be carried out precisely by hand by means of the hinge 12. The adjustment device can be used in clutches on machine tools of various types and also on drive devices, such as. B. Present.
Find application.
