Abstract

The invention relates to a winder for winding and unwinding metal strips with strip tensioning forces between 10 kN and 1000 kN. The winder consists of an expandable winding drum (1) supported on a hollow shaft (2) which is mounted in a stator (3). A driving rod (5) for actuating the expandable winding drum (1) passes through the hollow shaft (2). The driving rod (5) is the piston rod of a control cylinder (4) mounted on the opposite end of the hollow shaft (2) to the winding drum (1). To reduce the moment of inertia of the winder, to prevent play in the drive and to simplify the structure of the drum, the drive for the winder consists of a motor mounted in the stator (3) between the bearings (10, 11) of the hollow shaft (2), the rotor (13) of the motor being seated on the hollow shaft (2).

Die Erfindung bezieht sich auf einen Haspel zum Auf- und/oder Abwickeln von Metallbändern mit Bandzugkräften zwischen 10kN und 1000kN, bestehend aus einer spreizbaren Wickeltrommel, die von einer in einem Ständer zweifach gelagerten Hohlwelle getragen und über eine durch die The invention relates to a reel for winding and / or unwinding metal strips with strip tensile forces between 10kN and 1000kN, consisting of an expandable winding drum, which is supported by a hollow shaft which is mounted twice in a stand and via a through which

Hollow shaft arranged actuating cylinder can be actuated, and from a rotary drive coupled to the hollow shaft, which has a motor consisting of a stator and a rotor.

Ständers übertragen werden. Bei einer axialen Anordnung von Wickeltrommel, Hohlwelle und Antrieb müßten diese Stand are transferred. With an axial arrangement of the winding drum, hollow shaft and drive, these would have to

Deshalb ist es in der Praxis üblich, die Welle nicht mit einem axial angeordneten Antrieb, sondern mit einem neben der Welle angeordneten Antrieb, in der Regel unter  It is therefore common in practice not to have the shaft with an axially arranged drive, but with a drive arranged next to the shaft, usually under

Um einen großen Stellbereich zu haben, ist es üblich, als Antrieb eine Motorkombination von im Tandem betriebenen, einzeln zuschaltbaren Motoren und/oder ein Schaltgetriebe  Interposition of a transmission to be arranged. In order to have a large adjustment range, it is customary to drive a combination of motors operated in tandem, individually switchable motors and / or a manual transmission

Wegen der Vielzahl der am Antrieb beteiligten Bauteile hat der Haspel ein hohes Drive motor on the winding drum can not be realized practically. Because of the large number of components involved in the drive, the reel has a high height

Der Erfindung liegt die Aufgabe zugrunde, einen Haspel der eingangs genannten Art zu schaffen, der bei einem kleinen Massenträgheitsmoment konstruktiv einfacher als der bekannte Haspel ist. The invention has for its object to provide a reel of the type mentioned, which is structurally simpler than the known reel with a small moment of inertia.
Diese Aufgabe wird bei einem Haspel der eingangs genannten Art dadurch gelöst, daß der Motor im Ständer zwischen den beiden Lagern der Hohlwelle angeordnet ist, wobei sein This object is achieved in a reel of the type mentioned in that the motor is arranged in the stator between the two bearings of the hollow shaft
Läufer drehfest auf der Hohlwelle sitzt. The rotor is fixed on the hollow shaft.
Als Motor kommt vorzugsweise ein Elektromotor, insbesondere ein Drehstrommotor in Frage. An electric motor, in particular a three-phase motor, is preferably used as the motor.
Die erfindungsgemäße Integration des Antriebsmotors in den eigentlichen Haspel führt zu einem geringen Massenträgheitsmoment, weil der Motor keine eigene Welle und keine eigene Lagerung braucht, und zu einem spielfreien Antrieb, weil der Läufer unmittelbar auf der Hohlwelle der Wickeltrommel sitzt. Das Regelverhalten des Antriebes ist deshalb optimal. Insbesondere mit einem Drehstrommotor läßt sich ein Regelbereich im Zug von 1:30 bis 1 : 40 und im The inventive integration of the drive motor in the actual reel leads to a low level Mass moment of inertia because the motor does not need its own shaft and bearing, and for a backlash-free drive because the rotor sits directly on the hollow shaft of the winding drum. The control behavior of the drive is therefore optimal. In particular with a three-phase motor, a control range in the train from 1:30 to 1:40 and in
