Description

Die Erfindung betrifft eine Mühlenantriebvorrichtung für Wälzmühlen gemäß dem Oberbegriff des Anspruchs 1, wie beispielsweise aus DE 3240222A1 bekannt.The invention relates to a mill drive device for rolling mills according to the preamble of claim 1, such as, for example DE 3240222A1 known.

Wälzmühlen, welche eine rotierende Mahlschüssel mit darauf abrollenden, federnd anpressbaren Mahlwalzen aufweisen, werden vor allem zur Zerkleinerung von mineralischem Mahlgut, beispielsweise Zement-Rohmaterialien, Zement-Klinker, Kohle und auch zur Zerkleinerung von Erzen eingesetzt. In der Regel wird die Antriebsleistung für die Zerkleinerungsarbeit der Wälzmühlen von einer einzigen Antriebseinrichtung mit Antriebsmotor und Getriebe für den Drehantrieb der Mahlschüssel erbracht. Bekannt sind auch Wälzmühlen, bei welchen zusätzlich zu der Mahlschüssel die Mahlwalzen mit Hilfe von zusätzlichen Einzelantrieben angetrieben werden.Roller mills, which have a rotating grinding bowl with rolling-on, resiliently compressible grinding rollers, are used primarily for comminuting mineral ground material, for example cement raw materials, cement clinker, coal and also for comminuting ores. In general, the drive power for the crushing work of Wälzmühlen is provided by a single drive device with drive motor and gear for the rotary drive of the grinding bowl. Roller mills are also known in which, in addition to the grinding bowl, the grinding rolls are driven by means of additional individual drives.

In der Regel weist die Antriebseinrichtung für die Mahlschüssel ein Kegelradgetriebe und wenigstens ein Planetengetriebe auf und ist unterhalb der Mahlschüssel und mit dieser verbunden angeordnet.In general, the drive means for the grinding bowl on a bevel gear and at least one planetary gear and is arranged below the grinding bowl and connected thereto.

An Wälzmühlen werden immer größere Anforderungen bezüglich Durchsatzleistung und Effizienz bei möglichst geringen Kosten und kurzen Lieferzeiten gestellt. Die mit hohen Durchsatzleistungen verbundene Vergrößerung der Wälzmühlen führt zu einem entsprechend großen Mühlengetriebe und zum Einsatz eines relativ großen Antriebsmotors. Handelsübliche Normmotoren können dann nicht mehr eingesetzt werden, sondern es müssen Sonderausführung gefertigt werden, was zu erhöhten Kosten und längeren Lieferzeiten führt.At rolling mills ever greater demands are made in terms of throughput and efficiency at the lowest possible cost and short delivery times. The associated with high throughput capacity enlargement of the Wälzmühlen leads to a correspondingly large mill gear and the use of a relatively large drive motor. Commercially available standard motors can then no longer be used, but special designs have to be manufactured, which leads to increased costs and longer delivery times.

Aus dem deutschen Gebrauchsmuster DE-U-7620223 ist eine Schwerlastwälzmühle mit vier Hydraulikmotoren bekannt, die gemeinsam einen Zahnkranz und darüber den Mahlteller antreiben. Die vier Hydraulikantriebe ersetzen den aus einem einzigen Elektromotor und einem Schwerlastuntersetzungsgetriebe bestehenden herkömmlichen Mahltellerantrieb, um eine Drehzahländerung des Mühlenantriebs zu ermöglichen.From the German utility model DE-U-7620223 is a heavy-duty roller mill with four hydraulic motors known that drive together a sprocket and about the grinding table. The four hydraulic drives replace the conventional grinding table drive consisting of a single electric motor and a heavy duty reduction gearbox to allow a speed change of the mill drive.

Ferner ist aus DE3931116A eine Antriebseinrichtung für eine Rollenmühle bekannt, bei der zwei sich diametral gegenüberliegende Vorsatzgetriebe vorgesehen sind, die über je zwei Ritzel mit einem Zahnkranz in Eingriff stehen. Der Zahnkranz ist als Zahnkranzdruckplatte ausgebildet und dient gleichzeitig als Lauffläche für das Axial-Drucklager der Mahltellerwelle.Furthermore, it is off DE3931116A a drive device for a roller mill is known in which two diametrically opposed attachment gears are provided, which are in each case via two pinions with a ring gear in engagement. The sprocket is designed as a sprocket pressure plate and also serves as a running surface for the thrust bearing of the Mahltellerwelle.

Die Erfindung liegt die Aufgabe zugrunde, eine Mühlenantriebseinrichtung für Wälzmühlen zu schaffen, welches für Wälzmühlen jeder Größe und Nennleistung eingesetzt werden kann und mit relativ geringen Kosten und relativ kurzen Lieferzeiten verbunden ist und gleichzeitig eine optimierte Lastaufteilung aufweist.The invention has for its object to provide a mill drive device for roller mills which any size and power rating can be used for roller mills, and is associated with relatively low cost and relatively short delivery times and at the same time has an optimized load distribution.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Zweckmäßige und vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen und in der Zeichnungsbeschreibung enthalten.According to the invention the object is achieved by the features of claim 1. Advantageous and advantageous embodiments are contained in the dependent claims and in the drawing description.

Die Mühlenantriebsvorrichtung für Wälzmühlen, welche eine Kegelradstufe für den Krafteintrieb und wenigstens eine Planetenradstufe für den mahlschüsselseitigen Kraftabtrieb aufweist, ist gemäß der Erfindung im Bereich der Kegelradstufe anstelle einer einzigen, entsprechend großen Antriebseinrichtung mit mehreren separaten Antriebseinrichtungen bzw. Antrieben versehen.The mill drive device for rolling mills, which has a bevel gear for the power input and at least one planetary gear for the grinding bowl side power takeoff is provided according to the invention in the region of the bevel gear instead of a single, correspondingly large drive means with a plurality of separate drive means or drives.

Die separaten Antriebseinrichtungen der Kegelradstufe, welche zweckmäßigerweise um das Getriebegehäuse bzw. um ein gemeinsames Kegelrad angeordnet sind, ermöglichen die Verwendung kleinerer und insbesondere auch handelsüblicher Bauteile, beispielsweise von Elektromotoren, so dass eine erhebliche Kosteneinsparung und kürzere Lieferzeiten erreicht werden können.The separate drive means of the bevel gear, which are conveniently arranged around the gear housing or a common bevel gear, allow the use of smaller and especially commercially available components, such as electric motors, so that a significant cost savings and shorter delivery times can be achieved.

Die separaten Antriebseinrichtungen der Kegelradstufe weisen jeweils separate Kegelritzel auf, welche mit einem gemeinsamen Kegelrad der Kegelradstufe kämmen und ebenfalls eine entsprechende Ausbildung aufweisen und zur Kostensenkung beitragen können.The separate drive means of the bevel gear each have separate bevel pinions, which mesh with a common bevel gear of the bevel gear and also have a corresponding training and can contribute to cost reduction.

Ein weiterer wesentliche Vorteil der vorzugsweise gleichmäßig um das gemeinsame Kegelrad bzw. das Getriebegehäuse angeordneten separaten Antriebseinrichtungen besteht darin, dass bei Ausfall eines der mehreren Antriebe, bzw. eines der mehreren Elektromotore, die Wälzmühle mit den übrigen Antrieben weiterbetrieben werden kann. Bei einem Mühlengetriebe, dessen Kegelradstufe einen großen Antriebsmotor aufweist, führt desen Ausfall zum Stillstand der gesamte Mühle und zu Produktionsausfällen. Bei Ausfall einer der mehreren separaten Antriebseinrichtungen des erfindungsgemäßen Mühlengetriebes kann die Wälzmühle mit reduzierter Leistung weiterbetrieben und der defekte Antrieb ausgetauscht werden.Another essential advantage of the preferably uniformly arranged around the common bevel gear or the gear housing separate drive means is that in case of failure of one of the plurality of drives, or one of the plurality of electric motors, the roller mill can be operated with the other drives. In a mill gear, the bevel gear stage has a large drive motor, desen failure leads to a standstill of the entire mill and production losses. In case of failure of one of the several separate drive means of the mill gear according to the invention, the roller mill can continue to operate with reduced power and the defective drive to be replaced.

Es ist von Vorteil, dass Anzahl und/oder Leistung der separaten Antriebseinrichtungen variabel gestaltet und entsprechend der jeweils erforderlichen Leistung der Wälzmühle bestimmt werden könnenIt is advantageous that the number and / or power of the separate drive means can be made variable and can be determined according to the respective required power of the roller mill

Für die separaten Antriebseinrichtungen der Kegelradstufe können Horizontalmotoren eingesetzt werden. Jedoch können auch Vertikalmotoren Anwendung finden, welche mit ihren Stirnradritzeln in ein gemeinsames, horizontal liegendes Stirnrad eingreifen.For the separate drive means of the bevel gear horizontal motors can be used. However, vertical motors can be used, which engage with their Stirnradritzeln in a common, horizontally disposed spur gear.

Es ist zweckmäßig, eine elektrische Synchronisierung der separaten Antriebsmotoren vorzusehen, um eine optimierte Lastaufteilung zu unterstützen.It is expedient to provide an electrical synchronization of the separate drive motors in order to support an optimized load distribution.

Die Erfindung wird nachstehend anhand einer Zeichnung weiter beschrieben. Diese zeigt in einer einzigen Figur beispielhaft und in einer stark schematisierten Darstellung einen Vertikalschnitt durch ein erfindungsgemäßes Mühlengetriebe für eine Wälzmühle.The invention will be further described below with reference to a drawing. This shows in a single figure by way of example and in a highly schematic representation of a vertical section through an inventive mill gear for a roller mill.

Das Mühlengetriebe 2 ist in diesem Ausführungsbeispiel ein zweistufiges Wälzmühlengetriebe, welches in einem Getriebegehäuse 4 eine Kegelradstufe 10 und eine Planetenradstufe 5 aufweist.The mill gear 2 is in this embodiment, a two-stage Wälzmühlengetriebe, which has a bevel gear 10 and a planetary gear 5 in a gear housing 4.

Die Planetenradstufe 5 besteht aus einem Sonnenrad 6 im Zentrum, darum angeordneten Planetenrädern 7 und einem gemeinsamen Hohlrad 9 mit Innenverzahnung, in welchem sich die Planetenräder 7 abstützen. Abstand und Führung der Planetenräder 7 erfolgen durch einen Planetenradträger 8, welcher mit einem Abtriebsflansch 3 und einer darauf angeordneten Mahlschüssel (nicht dargestellt) über eine Abtriebswelle 19 drehfest verbunden ist.The planetary gear 5 consists of a sun gear 6 in the center, therefore arranged planetary gears 7 and a common ring gear 9 with internal toothing, in which the planet gears 7 are supported. Distance and guidance of the planetary gears 7 are effected by a planet carrier 8, which is connected to an output flange 3 and a grinding bowl (not shown) arranged thereon via an output shaft 19 in a rotationally fixed manner.

Das Sonnenrad 6 der Planetenradstufe 5 wird von der vorgeschalteten Kegelradstufe 10 über eine vertikale Antriebswelle 21 und eine Zahnkupplung 22 angetrieben, so dass die umlaufenden Planetenräder 7 gemeinsam den Planetenradträger 8 und damit den Abtriebsflansch 3 mit Mahlschüssel drehen.The sun gear 6 of the planetary gear 5 is driven by the upstream bevel gear 10 via a vertical drive shaft 21 and a toothed clutch 22, so that the rotating planetary gears 7 together rotate the planet 8 and thus the output flange 3 with grinding bowl.

Zur Optimierung der Lastübertragung im Bereich der Kegelradstufe 10 weist diese anstelle eines einzigen Hauptantriebs mehrere separate Antriebe auf, von denen in der Zeichnungsfigur nur zwei separate Antriebe 11, 12 gezeigt sind.To optimize the load transfer in the region of the bevel gear 10, this has several separate drives instead of a single main drive, of which only two separate drives 11, 12 are shown in the drawing figure.

Diese separaten Antriebe 11, 12 liegen einander gegenüber, und es ist offensichtlich, dass neben diesen zwei separaten Antrieben 11, 12 weitere Antriebe, insbesondere gleichmäßig zueinander beabstandet, um das gemeinsame Kegelrad 20 bzw. um das oder auch in dem Getriebegehäuse 4 angeordnet werden können. Beispielsweise können insgesamt vier separate Antriebe oder mehr als vier Antriebe, gegebenenfalls in Übereinstimmung mit der Anzahl der auf der Mahlschüssel abrollenden Mahlwalzen, angeordnet sein.These separate drives 11, 12 are opposite to each other, and it is obvious that in addition to these two separate drives 11, 12 further drives, in particular evenly spaced from each other, around the common bevel gear 20 or around or in the transmission housing 4 can be arranged , For example, a total of four separate drives or more than four drives, possibly in accordance with the number of rolling on the grinding bowl grinding rollers, may be arranged.

Jeder separate Antrieb 11, 12 weist ein separates Kegelritzel 15, 16 auf, welches jeweils über eine horizontale, separate Antriebswelle 13, 14 mit einem separaten Antriebsmotor (nicht dargestellt) verbunden ist.Each separate drive 11, 12 has a separate bevel pinion 15, 16, which in each case via a horizontal, separate drive shaft 13, 14 with a separate drive motor (not shown) is connected.

Die einzelnen Kegelritzel 15, 16 kämmen mit dem gemeinsamen Kegelrad 20 und treiben damit die vertikale Antriebswelle 21 und über die Planetenradstufe 5 die Abtriebswelle 19 und damit die Mahlschüssel an.The individual bevel pinions 15, 16 mesh with the common bevel gear 20 and thus drive the vertical drive shaft 21 and via the planetary gear 5, the output shaft 19 and thus the grinding bowl.

Das erfindungsgemäße Mühlengetriebe 2, welches nicht auf das dargestellte zweistufige Mühlengetriebe beschränkt ist, weist somit eine optimierte Lastaufteilung nicht nur in der Planetenradstufe 5, sondern auch in der darunter liegenden Kegelradstufe 10 auf.The mill gear 2 according to the invention, which is not limited to the illustrated two-stage mill gear, thus has an optimized load distribution not only in the planetary gear 5, but also in the underlying bevel gear stage 10.

Der Einsatz mehrerer separater Antriebseinrichtungen, welche entsprechend kleiner ausgebildet sind, ermöglicht die Verwendung handelsüblicher Bauteile, insbesondere von Elektromotoren, so dass aufwendige Sonderanfertigungen entfallen und Kostenvorteile und Lieferzeitvorteile entstehen.The use of a plurality of separate drive means, which are designed to be smaller, allows the use of commercially available components, in particular of electric motors, so that expensive special designs omitted and cost advantages and delivery advantages arise.

Die separaten, kleineren Antriebsmotoren (nicht dargestellt) können Horizontalmotoren oder auch Vertikalmotoren sein. Die separaten Elektromotoren der separaten Antriebseinrichtungen werden zudem zweckmäßigerweise über Kupplungen (nicht dargestellt) und damit lösbar und austauschbar mit den jeweiligen Antriebswellen verbunden, so dass erforderlichenfalls ein rascher Austausch erfolgen kann.The separate, smaller drive motors (not shown) may be horizontal motors or vertical motors. The separate electric motors of the separate drive devices are also conveniently connected via couplings (not shown) and thus releasably and replaceably connected to the respective drive shafts, so that if necessary, a rapid exchange can take place.
