Description

Die- Erfindung bezieht sich auf eine Vorrichtung -zum wechselweisen, Arbeiten zweier Motoren auf eine gemeinsame Triebwelle. Vorrichtungen dieser Art finden in der Technik ein weites Anwendungsgebiet; sie können z. B. bei Arbeitsmaschinen Verwendung finden, bei denen es auf einen genauen Vorschub, eine genaue Einstellung eines Maschinenelementes und eines Werkzeuges u. dgl. ankommt. In diesem Fall dient der eine Motor zur Grobeinstellung, während der zweite Motor die Genaueinstellung herbeiführt.The invention relates to a device for changing Two motors work on a common drive shaft. Devices of this type find a wide field of application in technology; you can z. B. in working machines Use where there is an exact feed, an exact setting of a machine element and a tool and the like. In this case it serves one motor for coarse adjustment, while the second motor for precise adjustment brings about.

Erfindungsgemäß soll die Vorrichtung in erster Linie bei aus dem Stand schneidenden Scheren benutzt werden, wie sie in Feinwalzwerken Anwendung finden, und zwar zur Unterteilung laufenden' Walzgutes. Bei diesen Scheren kommt es darauf an, die rotierenden Messer kurzzeitig und auf einem kurzen Drehausschlag in die Ausgangsstellung nach jedem Schnitt zurückzubringen. Praktisch stößt dies bei der hohen Umlaufgeschwindigkeit auf Schwierigkeiten, da eine derart genaue Abbremsung der Messerträger nicht möglich ist.According to the invention, the device is primarily intended for from the state cutting shears are used, as they are used in fine rolling mills, namely for the subdivision of rolling stock. With these scissors, it depends on, the rotating knives briefly and with a short rotary stroke in the Bring back the starting position after each cut. In practice, this happens with the high rotational speed on difficulties, since such an accurate braking the knife carrier is not possible.

Bei Anwendung der neuen Vorrichtung werden diese Schwierigkeiten behoben. Die Vorrichtung, die mit zwei Motoren ausgerüstet ist, die wechselweise zur Anwendung kommen, kennzeichnet sich dadurch, daß-mit dem drehbar gelagerten und mit dem die Triebwelle antreibenden zugehörigen Rotor kuppelbaren Stator des einen Motors der zweite Motor durch ein Getriebe verbunden ist. Der erstgenannte Motor dient bei dem hier betrachteten Anwendungsfall dazu, kurzzeitig den größten Teil des Rücklaufes der Messerträger 'herbeizuführen, während daran anschließend bei inzwischen erfolgter Kupplung des Stators mit dem Rotor mit Hilfe des zweiten Motors die Genaueinstellung der Triebwellen und damit der Messerträger bzw. der Messer auf einer kurzen Wegstrecke erfolgt.Using the new device eliminates these difficulties. The device, which is equipped with two motors, which are used alternately come, is characterized in that -with the rotatably mounted and with the Drive shaft driving associated rotor of the detachable stator of a motor second motor is connected by a gearbox. The former engine is used the application considered here, briefly the largest part of the return the knife bearer 'to bring about, while then afterwards in the meantime Coupling of the stator with the rotor with the help of the second motor enables the precise adjustment the drive shafts and thus the knife carrier or knife over a short distance he follows.

In der Zeichnung ist die neue Vorrichtung schematisch dargestellt.In the drawing, the new device is shown schematically.

. _ Aus der Abbildung ist ersichtlich, daß der Stator 'i des aus diesem und dem Rotor 2 bestehenden Elektromotors in Lagern 3 und q. drehbar gelagert ist. Durch den Schneckentrieb, der aus dem Schneckenrad 5 am Stator i und der Sc'hnec'ke 6 gebildet ist, wird,das Motorgehäuse in seiner Lage festgelegt. Die Bremsscheibe 7 auf der Motorwelle g bildet mit der Magnetwicklung 8 eine Bremskupplung. Wird diese zum Ansprechen gebracht, so findet mit der Abbremsung des Motors gleichzeitig eine Kupplung des Rotors 2 bzw. seiner Welle g mit dem Stator i statt. Mit Hilfe des nicht gezeichneten, die Schnecke 6 treibenden Motors kann nunmehr über den Stator i die Motorwelle weiter angetrieben werden.. _ From the figure it can be seen that the stator 'i der from this and the rotor 2 existing electric motor in bearings 3 and q. is rotatably mounted. By the worm drive, which consists of the worm wheel 5 on the stator i and the Sc'hnec'ke 6 is formed, the motor housing is set in its position. The brake disc 7 on the motor shaft g forms a brake clutch with the magnet winding 8. Will this is brought to response, takes place with the braking of the motor at the same time a coupling of the rotor 2 or its shaft g to the stator i instead. With help the motor, not shown, driving the worm 6 can now be via the stator i the motor shaft can continue to be driven.
