Abstract

Die Erfindung betrifft eine Walzenmühle mit zwei gegenläufig angetriebenen Walzen (1,2), wobei die beiden Getriebegehäuse (3,4) direkt durch eine ein elastisches Glied (27) enthaltende Drehmomentenabstützung miteinander verbunden sind.The invention relates to a roller mill with two rollers (1, 2) driven in opposite directions, the two gear housings (3, 4) being connected directly to one another by a torque support containing an elastic member (27).

Description

Die Erfindung betrifft eine Walzenmühle entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a roller mill according to the preamble of claim 1.

Bei den bisher bekannten Walzenmühlen der im Ober­begriff des Anspruches 1 vorausgesetzten Art sind die Getriebegehäuse der beiden Walzen über je eine Drehmomentenstütze am Maschinenrahmen abgestützt. Im Hinblick auf die auftretenden hohen Drehmomente erfordern diese Drehmomentenstützen einen beträcht­lichen konstruktiven Aufwand.In the previously known roller mills of the type required in the preamble of claim 1, the gearboxes of the two rollers are each supported on the machine frame via a torque arm. In view of the high torques that occur, these torque supports require considerable design effort.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Walzenmühle der im Oberbegriff des Anspruches 1 vorausgesetzten Art so auszubilden, daß der kon­struktive Aufwand für die Drehmomentenabstützung wesentlich verringert ist.The invention is therefore based on the object of designing a roller mill of the type required in the preamble of claim 1 in such a way that the structural outlay for the torque support is substantially reduced.

Diese Aufgabe wird erfindungsgemäß durch die kenn­zeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Zweckmäßige Ausgestaltungen der Erfindung sind Ge­genstand der Unteransprüche.Appropriate embodiments of the invention are the subject of the dependent claims.

Bei der erfindungsgemäßen Lösung werden die Dreh­momente fast vollständig zwischen den Getriebege­häusen der beiden Walzen gegeneinander abgestützt. Nur ein eventuelles Restdrehmoment, das aus einer möglichen Differenz beider Drehmomente resultiert, wird durch eine einfache Drehmomentstütze am Maschinenrahmen abgestützt. Auf diese Weise ergeben sich in der Maschinenkonstruktion erhebliche Er­sparnisse.In the solution according to the invention, the torques are almost completely supported against one another between the gear housings of the two rollers. Only a possible residual torque that from a possible difference between the two torques is supported by a simple torque arm on the machine frame. This results in considerable savings in machine construction.

  • Fig.1 eine Längsansicht der Walzenmühle,
  • Fig.2 eine teilweise geschnittene bzw. aufgebrochene Querschnitt,
  • Fig.3 eine Aufsicht auf die für das Ver­ständnis der Erfindung wesentlichen Teile der Walzenmühle.
An embodiment of the invention is shown in the drawing. Show it
  • 1 shows a longitudinal view of the roller mill,
  • 2 shows a partially cut or broken cross section,
  • 3 shows a top view of the parts of the roller mill that are essential for understanding the invention.

Die dargestellte Walzenmühle, die beispielsweise zur Zerkleinerung von sprödem Gut, wie Zement­klinker, bestimmt ist, enthält zwei Walzen 1, 2, die über Getriebe 3, 4 gegenläufig angetrieben und durch Hydraulikzylinder 5, 6 mit großer Anpreß­kraft gegeneinander gedrückt werden. Dabei ist die Walze 1 als Festwalze ausgebildet und in einem Festlagerstein 7 angeordnet, während die Walze 2 als Loslagerwalze ausgebildet und in einem Loslager­stein 8 angeordnet ist. Der von den Hydraulik­zylindern 5, 6 beaufschlagte Loslagerstein 8 ist in einem Verschiebelager 9 in Richtung des Pfeiles 10 verschiebbar.The roller mill shown, which is intended, for example, for comminuting brittle material, such as cement clinker, contains two rollers 1, 2, which are driven in opposite directions via gears 3, 4 and are pressed against one another by hydraulic cylinders 5, 6 with great contact pressure. The roller 1 is designed as a fixed roller and arranged in a fixed bearing block 7, while the roller 2 is designed as a floating bearing roller and is arranged in a floating bearing block 8. The floating bearing block 8 acted upon by the hydraulic cylinders 5, 6 is in a displacement bearing 9 in the direction of the arrow 10 slidable.

Der Maschinenrahmen ist mit 11 und der Aufgabe­schacht für den Walzenspalt mit 12 bezeichnet.The machine frame is designated 11 and the feed chute for the roll nip 12.

Fig.2 läßt die Einzelheiten der Lagerung der Los­walze 2 erkennen: In dem aus Oberrahmen 11a und Unterrahmen 11b bestehenden Maschinenrahmen sind zwei Verschiebelager 13, 14 für die äußeren Lager­ringe 15, 16 der Lager 17, 18 vorgesehen, die die Welle 2a der Loswalze 2 aufnehmen.2 shows the details of the mounting of the loose roller 2: In the machine frame consisting of the upper frame 11a and the lower frame 11b, two sliding bearings 13, 14 are provided for the outer bearing rings 15, 16 of the bearings 17, 18, which hold the shaft 2a of the loose roller 2 record, tape.

Zwischen den beiden Getrieben 3 und 4 ist eine Drehmomentenabstützung zur Aufnahme des auf die beiden Walzen 1, 2 ausgeübten, gegensinnigen Hauptdrehmomentes vorgesehen. Diese Drehmomenten­abstützung enthält zwei Koppeln 19, 20, die auf radial einander gegenüberliegenden Seiten der Los­walzenwelle über Achsen 21, 22 gelenkig mit An­sätzen 4a, 4b des Gehäuses des Getriebes 4 der Loswalze 2 verbunden sind.A torque support is provided between the two gears 3 and 4 for receiving the opposing main torque exerted on the two rollers 1, 2. This torque support contains two couplers 19, 20, which are articulated on axially opposite sides of the idler roller shaft via axles 21, 22 with lugs 4a, 4b of the housing of the gear 4 of the idler roller 2.

Die Koppeln 19, 20 sind an ihrem anderen, ge­schlitzten Ende über quer zu den Koppeln verlau­fende Achsen 23, 24 schwenkbar mit Koppelhebeln 25, 26 verbunden.The couplers 19, 20 are pivotally connected to coupling levers 25, 26 at their other, slotted end via axes 23, 24 extending transversely to the couplers.

Eine an ihren beiden Enden drehfest mit den Kop­pelhebeln 25, 26 verbundene Koppelachse 27 ist als Torsionswelle ausgebildet und in Koppelachsen­ lagern 28, 29 gelagert, die auf radial einander gegenüberliegenden Seiten der Festwalzenwelle mit Ansätzen 3a, 3b des Gehäuses des Getriebes 3 der Festwalze verbunden sind.A coupling axis 27 connected at both ends to the coupling levers 25, 26 in a rotationally fixed manner is designed as a torsion shaft and in coupling axes store 28, 29 mounted, which are connected on radially opposite sides of the fixed roller shaft with lugs 3a, 3b of the housing of the gear 3 of the fixed roller.

Durch die vorstehend beschriebene Drehmomentenab­stützung zwischen den Getrieben 3 und 4 wird das gegensinnige Hauptdrehmoment der beiden gegen­läufig angetriebenen Walzen 1 und 2 vollständig aufgenommen. Die als Torsionswelle ausgebildete Koppelachse 27 gestattet dabei Relativbewegungen der Loswalze 2 (in Richtung des Pfeiles 10) relativ zur Festwalze 1.The torque support between the gears 3 and 4 described above completely absorbs the opposite main torque of the two rollers 1 and 2 driven in opposite directions. The coupling axis 27 designed as a torsion shaft permits relative movements of the loose roller 2 (in the direction of arrow 10) relative to the fixed roller 1.

Nur ein aus einer etwaigen Drehmomentendifferenz resultierendes Differenzdrehmoment muß am Maschinenrahmen 11 abgestützt werden. Zu diesem Zweck ist der Ansatz 3b des Getriebes 3 der Fest­walze 1 nach unten verlängert und stützt sich über Abstützelemente 30, 31 am Maschinenrahmen 11 ab.Only a differential torque resulting from a possible torque difference has to be supported on the machine frame 11. For this purpose, the approach 3b of the gear 3 of the fixed roller 1 is extended downward and is supported on the machine frame 11 by means of support elements 30, 31.
