Reibscheibengetriebef insbesondere für Spindslpressen,wurden früher derart gesteuert * daß die Seitenscheiben von Hand angepreßt und abgehoben wtirucn» Seit Jahrzehnten ist es üblich, die Hand durch einen Servomotor zu ersetzen. Üblicherweise wird der Servomotor duarteb !/.ruekruft gesteuert, die durchweg d*m Dr\ickiuftnetz des Betriebe« entnommen wird· Die Zuführung der Druckluft geschieht auf dem Umwege über Elektromagnetventile. Diese sind teuer, außerdem geht dabei Zeit verloren· Die vorliegende Erfindung stellt sich die Aufgabe, die Steuerung der Reibscheiben zu verbilligen und den Steuervorgang abzukürzen. Die Lösung wird in der Anwendung eines Elektromagneten gesehen, der unmittelbar auf die Reibscheibenwelle einwirkt.Friction disc gears especially for screw presses previously controlled in such a way * that the side windows are pressed on by hand and lifted wtirucn »For decades it has been common practice to use the Replace hand with a servo motor. The servomotor is usually controlled by dual calls, which are consistently controlled by the pressure air network des Betriebs «is taken · The supply of compressed air happens indirectly via solenoid valves. These are expensive, moreover time is lost. The object of the present invention is to control the to make the friction disks cheaper and to shorten the control process. The solution is seen in the application of an electromagnet, which acts directly on the friction disk shaft.
Die Abbildung stellt ein Aueführungsbeispiel des Erfindungsgegenstandes
dar. Die Seitenscheibe 1 ist auf der Welle 2 angeordnet^ die axial verschiebbar ist. Sie ist in einem Lagerbock 3 gelagert
und kann gegen die Mittelscheibe 4 angepreßt werden. Dazu dient ein Elektromagnet, bestehend aus der Magnetspule 5 und der ruf
der kurzen Achse 6 festsitzenden Magnetscheibe 7, di®, wenn die
Spule 5 unter Strom steht, angezogen wird, wodurch die Seiten-•cheibe
1 gegen die Mittelscheibe k gepreßt wird. Nach Ausschalten
des Stromu· drückt die Feder 8 die Magnetscheibe 7 und damit die
Seitenscheibe 1 in die Ausgangsstellung zurück. Zwischen der um»,-laufenden
Welle 2 und der nur axial bewegten Achse 6 ist ein Kugellager zwischflngaschaatet. Zur Einstellung des Megnetspaltee
^ kann die Magnetscheibe 7 gegen den Wideretand von Tellerfedern
to durch eine Mutter 9 verschoben
OThe figure shows an exemplary embodiment of the subject matter of the invention. The side disk 1 is arranged on the shaft 2, which is axially displaceable. It is mounted in a bearing block 3 and can be pressed against the center disk 4. An electromagnet is used for this, consisting of the magnetic coil 5 and the magnetic disk 7, which is fixed on the short axis 6 and which is attracted when the coil 5 is energized, whereby the side disk 1 is pressed against the central disk k. After switching off the power, the spring 8 pushes the magnetic disk 7 and thus the side disk 1 back into the starting position. Between the rotating shaft 2 and the axis 6, which is only moved axially, there is a ball bearing interposed. To adjust the Megnetspaltee ^ the magnetic disk 7 can be moved against the resistance of disc springs to by a nut 9
