In der Zeichnung ist die erfindungsgemässe Drehtrommel in Form einer Rohrmühle 1 veranschaulicht. Gemäss Fig. 1 kann diese Rohrmühle 1 weitgehend in an sich bekannter Weise ausgeführt und aufgebaut sein. Sie besitzt einen Drehtrommelmantel 2 und - im veranschaulichten Ausführungsbeispiel - an einem Stirnende, nämlich dem Einlaufstirnende, einen in einen Hohlzapfen 3 führenden Mahlguteinlauf 4 sowie am anderen Stirnende (Auslaufstirnende) einen weiteren Hohlzapfen 5, aus dem genügend zerkleinertes Mahlgut (Pfeil 6) aus der Mühle austritt.The rotary drum according to the invention is illustrated in the drawing in the form of a tube mill 1. 1, this tube mill 1 can be largely constructed and constructed in a manner known per se. It has a rotating drum jacket 2 and - in the illustrated embodiment - at one end, namely the inlet end, a grist inlet 4 leading into a hollow spigot 3 and at the other end (outlet end) another hollow spigot 5, from which sufficiently ground material (arrow 6) from the Mill emerges.

An der Aussenumfangsseite des Drehtrommelmantels 2 dieser in Fig. 1 veranschaulichten Drehtrommelmühle 1 ist koaxial dazu ein erster Laufring 7 im Bereich des Einlaufstirnendes befestigt, wobei dieser erste Laufring 7 auf üblichen Lagerelementen abgestützt sein kann, d. h. entweder auf Laufrollen oder - wie in Fig. 1 angedeutet - auf hydrostatischen oder hydrodynamischen Gleitlagerschuhen 8. Im Bereich des anderen Stirnendes ist an der Aussenumfangsseite des Drehtrommelmantels 2 koaxial ein zweiter Laufring 9 befestigt, der in gleichartiger Weise wie der erste Laufring 7 auf an sich bekannten Lagerelemente, insbesondere auf hydrostatischen oder hydrodynamischen Gleitlagerschuhen 10 drehbeweglich abgestützt ist.On the outer circumferential side of the rotating drum jacket 2 of this rotating drum mill 1 illustrated in FIG. 1, a first race 7 is fastened coaxially to it in the region of the inlet end, whereby this first race 7 can be supported on conventional bearing elements, i. H. either on rollers or - as indicated in Fig. 1 - on hydrostatic or hydrodynamic plain bearing shoes 8. In the area of the other front end on the outer circumferential side of the rotating drum shell 2, a second race 9 is fastened coaxially, in a manner similar to the first race 7 itself known bearing elements, in particular on hydrostatic or hydrodynamic plain bearing shoes 10 is rotatably supported.

Ebenfalls koaxial an der Aussenumfangsseite des Drehtrommelmantels 2 ist ein Zahnkranz 11 drehfest angeordnet, der - wie im folgenden noch näher erläutert wird - direkt am zweiten Laufring 9 befestigt ist und damit eine Baueinheit bildet. Dieser Zahnkranz 11 steht mit wenigstens einem Antriebszahnritzel 12 (vgl. Fig. 3, rechte Hälfte) in Zahneingriff, das Teil eines noch zu erläuternden Drehtrommelantriebes 13 ist.Also coaxially on the outer circumferential side of the rotating drum jacket 2, a ring gear 11 is arranged in a rotationally fixed manner, which - as will be explained in more detail below - is fastened directly to the second race 9 and thus forms a structural unit. This ring gear 11 is in mesh with at least one drive pinion 12 (see FIG. 3, right half), which is part of a rotary drum drive 13 to be explained.

Anhand der Fig. 2 sei insbesondere eine Ausführungsform der Baueinheit aus Zahnkranz 11 und zweitem Laufring näher erläutert.An embodiment of the assembly consisting of ring gear 11 and second race is to be explained in more detail with reference to FIG. 2.

In diesem Beispiel ist der zweite Laufring 9 an seinen beiden axialen Stirnenden mit je einem radial verlaufenden Ringflansch 9a und 9b versehen, die - gemäss Fig. 2 - beide radial nach aussen vorstehen. Durch den ersten Ringflansch 9a ist der Laufring 9 mit einem stirnseitigen Endflansch 2a des Drehtrommmelmantels 2 verschraubt (wie durch strichpunktierte Linie angedeutet), so dass der zweite Laufring 9 eine unmittelbare axiale Verlängerung des Drehtrommelmantels 2 darstellt, jedoch eine grössere Materialdicke als der Trommelmantel 2 aufweist (vgl. Fig.2).In this example, the second race 9 is provided at its two axial ends with a radially extending ring flange 9a and 9b, which - according to FIG. 2 - both protrude radially outwards. Through the first ring flange 9a, the race 9 is screwed to an end flange 2a of the rotating drum casing 2 (as indicated by a dash-dotted line), so that the second race 9 represents an immediate axial extension of the rotating drum casing 2, but has a greater material thickness than the drum casing 2 (see Fig. 2).

An der zweiten Ringflansch 9b dieses Laufringes 9 ist der Zahnkranz 11 fest angeschraubt (vgl. strichpunktiert angedeutete Mittellinie 14 der Schrauben), der in seinem Aussendurchmesser etwas grösser gehalten ist als der Laufring 9. Der Zahnkranz 11 weist zweckmässig einen T-förmigen Querschnitt auf, dessen radial nach innen verlaufender Steg 11 gleichzeitig eine Art Befestigungsflansch bildet und als Gegenflansch zum Laufringflansch 9b dient, während auf der Aussenumfangsseite des T-förmigen Flansches die Zähne 11 b vorgesehen sind.On the second ring flange 9b of this race 9, the ring gear 11 is firmly screwed on (see dash-dot center line 14 of the screws), the outer diameter of which is kept somewhat larger than that of the race ring 9. The ring gear 11 expediently has a T-shaped cross section, whose radially inwardly extending web 11 simultaneously forms a type of fastening flange and serves as a counter flange to the race flange 9b, while the teeth 11b are provided on the outer peripheral side of the T-shaped flange.

In vorteilhafter Weise ist somit der Zahnkranz 11 axial von aussen her fest und doch leicht montierbar und auswechselbar am äusseren Ende des zweiten Laufringes 9 und damit am axial äusseren Ende des Drehtrommelmantels 2 angebracht. Aufgrund dieser Anordnung kann der Zahnkranz 11 zweckmässig in Form eines ungeteilten (einteiligen) Ringes ausgeführt sein, der sich durch eine geringe Bauhöhe auszeichnet. Gleichzeitig sind vorzugsweise die axialen Stirnseiten dieses Zahnkranzes 11 und insbesondere von dessen T-Flansch 11c c so ausgebildet, dass sie als axiale Führungsflächen 15, 15a dienen können.Advantageously, the ring gear 11 is thus fixed axially from the outside and yet is easy to install and replace on the outer end of the second race 9 and thus on the axially outer end of the rotating drum shell 2. Because of this arrangement, the ring gear 11 can expediently be designed in the form of an undivided (one-piece) ring which is distinguished by a low overall height. At the same time, the axial end faces of this ring gear 11 and in particular of its T-flange 11c c are preferably designed such that they can serve as axial guide surfaces 15, 15a.

Zumindest im unteren Umfangsbereich der Rohrmühle 1 bzw. des Drehtrommelmantels 2 sind ortsfest (z. B. am Fundament 16) zwei Halterungen 17, 17a angeordnet, die nach Art von Teil-Ringflanschen ausgebildet sein können und auf ihren gegeneinanderweisenden Seiten jeweils Gleitklötze 18, 18a aus reibungsgünstigem Material tragen, die mit den axialen Führungsflächen 15,15a des Zahnkranzes 11 in Gleiteingriff stehen. Auf diese Weise bilden die axialen Führungsflächen 15, 15a mit den ortsfest gehalterten Gleitklötzen 18, 18a eine Axialführung für die Baueinheit aus Zahnkranz 11 und Laufring 9.At least in the lower circumferential area of the tube mill 1 or the rotating drum casing 2, two brackets 17, 17a are arranged in a fixed position (e.g. on the foundation 16), which can be designed in the manner of partial ring flanges and have sliding blocks 18, 18a on their mutually opposing sides wear from low-friction material, which are in sliding engagement with the axial guide surfaces 15, 15a of the ring gear 11. In this way, the axial guide surfaces 15, 15a, together with the stationary sliding blocks 18, 18a, form an axial guide for the assembly comprising the toothed ring 11 and the raceway 9.

Auf dem Fundament 16, auf dem sich die Gleitlagerschuhe 10 des zweiten Laufringes 9 und der Drehtrommelantrieb 13 abstützen (vgl. Fig. 2 und 3), ist ferner ortsfest ein gemeinsames Gehäuse 19 für diese Gleitlagerschuhe 10 und den Dreh-. trommelantrieb 13 vorgesehen. Wie sich besonders aus Fig. 3 ersehen lässt, ist dieses Gehäuse 19 aus einer Anzahl von segmentartigen Gehäuseteilen 19a leicht montierbar und demontierbar zusammengesetzt, und zwar in der Weise, dass das gemeinsame Gehäuse 19 auch gleichzeitig die Baueinheit aus zweitem Laufring 9 und Zahnkranz 11 schützend umgibt.On the foundation 16, on which the slide bearing shoes 10 of the second race 9 and the rotary drum drive 13 are supported (see FIGS. 2 and 3), there is also a common housing 19 for these slide bearing shoes 10 and the rotary bearing. drum drive 13 provided. As can be seen particularly from FIG. 3, this housing 19 is easily assembled and disassembled from a number of segment-like housing parts 19a, in such a way that the common housing 19 also protects the assembly of the second race 9 and ring gear 11 at the same time surrounds.

Dieses gemeinsame Gehäuse 19 bzw. dessen Gehäuseteile 19a ist bzw. sind dabei mit axialen Stirnwänden 19b und 19c versehen, an deren radial inneren Rändern geeignete Dichtungselemente 20 gehaltert sind, die mit der Aussenumfangsseite des Laufringes 9 bzw. einer am Zahnkranz 11 entsprechend vorgesehenen axialen, ringförmigen Verlängerung 21 in Reibungs- bzw. Dichtungseingriff stehen.This common housing 19 or its housing parts 19a is or are provided with axial end walls 19b and 19c, on the radially inner edges of which suitable sealing elements 20 are held, which are connected to the outer circumferential side of the race 9 or a correspondingly provided on the ring gear 11, annular extension 21 are in frictional or sealing engagement.

Die zuvor geschilderte Ausbildung und Anordnung des Gehäuses 19 ist eine besonders günstige Voraussetzung dafür, dass der Zahnkranz 11 und dessen Antriebsritzel 12 sowie der zweite Laufring 9 und dessen Lagerelemente (Gleitlagerschuhe 10) eine gemeinsame Ölumlaufschmierung besitzen können, die üblicher Ausführung sein kann und daher nicht näher veranschaulicht ist. Innerhalb dieses gemeinsamen Gehäuses 19 befinden sich auch die stationären Gleitklötze 18,18a der weiter oben beschriebenen Axialführung für die Baueinheit aus Laufring 9 und Zahnkranz 11.The previously described design and arrangement of the housing 19 is a particularly favorable prerequisite for the gear rim 11 and its drive pinion 12, as well as the second race 9 and its bearing elements (slide bearing shoes 10), to be able to have common oil circulation lubrication, which can be of the customary design and therefore not is illustrated in more detail. Within this common housing 19 are also the stationary sliding blocks 18, 18a of the axial guide described above for the assembly consisting of the race 9 and ring gear 11.

Es kann ferner zweckmässig sein, wenn zumindest der Drehtrommelantrieb 13 gegenüber dem Zahnkranz 11 sowie ggf. ausserdem die Lagerschuhe 10 des Laufringes 9 mit dem gemeinsamen Gehäuse 19 gegenüber der Baueinheit aus Laufring 9 und Zahnkranz 11 nachstellbar angeordnet sind, was sich insbesondere für die Montage, aber auch für eine spätere Nachrichtmöglichkeit günstig auswirkt.It may also be expedient if at least the rotary drum drive 13 is arranged to be adjustable with respect to the ring gear 11 and possibly also the bearing shoes 10 of the race 9 with the common housing 19 with respect to the assembly of the race 9 and ring gear 11, which is particularly useful for assembly, but also has a favorable effect for a later message possibility.

In Fig. 3 (rechte Hälfte) ist der angedeutete Drehtrommelantrieb 13 so ausgebildet und angeordnet, dass er ein Abtriebszahnritzel aufweist, das gleichzeitig das Antriebsritzel 12 für den Zahnkranz 11 bildet. Dies bedeutet neben einer beträchtlichen Platzeinsparung auch, dass zwischengeordnete Antriebselemente, wie z. B. Kupplungen, Wellen, separate Lager usw., entfallen können. Das Drehmoment des Getriebeabtriebsritzels wird somit direkt auf den Zahnkranz 11 der Rohrmühle 1 übertragen.3 (right half), the indicated rotary drum drive 13 is designed and arranged in such a way that it has an output pinion, which at the same time forms the drive pinion 12 for the ring gear 11. In addition to a considerable saving of space, this also means that intermediate drive elements, such as. B. couplings, shafts, separate bearings, etc. can be omitted. The torque of the transmission output pinion is thus transmitted directly to the ring gear 11 of the tube mill 1.

In Fig. 3 sind ferner die beiden Hauptausbildungsmöglichkeiten für die unterhalb der Rohrmühle 1 stationär angeordneten Lagerelemente für den Laufring 9 angedeutet. Danach ist in der rechten Hälfte der Fig. 3 der Laufring 9 auf mehreren (insgesamt vorzugsweise vier) Gleitlagerschuhen 10 gleitend und drehbeweglich abgestützt, während nach der linken Zeichnungshälfte (Fig. 3) vorzugsweise zwei symmetrisch zur vertikalen Längsmittelebene 1a der Rohrmühle 1 angeordnete Laufrollen 22 für eine drehbewegliche Abstützung der Rohrmühle 1 über den Laufring sorgen.In Fig. 3, the two main training options for the bearing elements arranged stationary below the tube mill 1 for the race 9 are also indicated. Thereafter, in the right half of FIG. 3, the race 9 is slidably and rotatably supported on several (preferably four in total) slide bearing shoes 10, while according to the left half of the drawing (FIG. 3) preferably two rollers 22 arranged symmetrically to the vertical longitudinal center plane 1 a of the tube mill 1 ensure rotatable support of the tube mill 1 via the race.

Der Teilquerschnitt gemäss Fig. 4 zeigt eine Ausführungsvariante des Drehtrommelantriebes 13', deren Unterschied zu der vorhergehenden Beschreibung in der Hauptsache darin besteht, dass der Drehtrommelantrieb 13' zwei Abtriebszahnritzel besitzt, die gleichzeitig je ein Antriebszahnritzel 12' für den Zahnkranz 11 bilden. In vorteilhafter und platzsparender Weise können diese beiden Antriebszahnritzel 12' vertikal übereinander angeordnet sein. Ansonsten unterscheidet sich diese Ausführungsvariante gemäss Fig. 4 nicht von der vorher beschriebenen Ausführungsform.The partial cross section according to FIG. 4 shows a variant of the rotary drum drive 13 ', the main difference from the previous description is that the rotary drum drive 13' has two driven pinions, each of which simultaneously forms a drive pinion 12 ' for the ring gear 11. In an advantageous and space-saving manner, these two drive pinions 12 'can be arranged vertically one above the other. Otherwise, this embodiment variant according to FIG. 4 does not differ from the previously described embodiment.

Zur Ausbildung und Anordnung jedes Antriebszahnritzels 12 bzw. 12' sei noch bemerkt, dass es vorgezogen wird, dieses mit der zugehörigen Abtriebswelle des Drehtrommelantriebes 13 bzw. 13' selbsteinstellend auszuführen. Auf diese Weise können gelegentlich auftretende geringe axiale Verlagerungen oder Verschiebungen des Drehtrommelmantels 2 ausgeglichen werden.Regarding the design and arrangement of each drive pinion 12 or 12 ', it should also be noted that it is preferred to do this self-adjusting with the associated output shaft of the rotary drum drive 13 or 13'. In this way, occasional minor axial displacements or displacements of the rotating drum shell 2 can be compensated for.

Im Rahmen der Erfindung sind seblstverständlich noch zahlreiche Abwandlungen und Modifikationen möglich. So kann beispielsweise - wie in Fig. 2 gezeigt - der Laufring 9 an seiner Innenumfangseite einen etwa radial nach innen verlaufenden, stegartigen Flansch 23 zwecks weiterer Versteifung des Laufringes aufweisen. Ferner kann dieser Laufring 9 - anstelle der Flanschverbindung mit den Flanschen 2a und 9a - direkt axial gegen das ihm zugewandte Stirnende des Drehtrommelmantels 2 geschweisst sein (wie es an sich bekannt ist), wobei jedoch an der anderen Stirnseite des Laufringes 9 in jedem Falle ein Ringflansch (z. B. 9b) für die Befestigung des Zahnkranzes 11 vorhanden ist.Numerous modifications and modifications are of course still possible within the scope of the invention. For example, as shown in FIG. 2, the race 9 can have a web-like flange 23 running approximately radially inwards on its inner circumferential side for the purpose of further stiffening the race. Furthermore, this race 9 - instead of the flange connection with the flanges 2a and 9a - directly axially welded against the end face of the rotating drum jacket 2 facing it (as is known per se), but in any case on the other end face of the race 9 Ring flange (z. B. 9b) for the attachment of the ring gear 11 is available.

Eine weitere Ausführungsvariante ist in Fig. 1 strichpunktiert angedeutet. Danach muss die Baueinheit aus Zahnkranz und Laufring nicht unbedingt im Bereich der Aussenumfangsseite des Trommelmantels 2 angebracht sein, sondern diese Baueinheit kann - wie bei 24 strichpunktiert angedeutet - auch auf der Aussenumfangsseite des einen Lager- bzw. Hohlzapfens, im dargestellten Falle des Hohlzapfens 5 am Auslauf, befestigt sein. Die Ausbildung und Zusammenordnung kann in diesem Falle jedoch - bei entsprechender Anpassung - gleichartig wie in den zuvor geschilderten Fällen sein.A further embodiment variant is indicated by dash-dotted lines in FIG. 1. Thereafter, the assembly of the ring gear and the race does not necessarily have to be attached in the area of the outer circumferential side of the drum shell 2, but this structural unit can - as indicated by dash-dotted lines at 24 - also on the outer circumferential side of the one bearing or hollow journal, in the case of the hollow journal 5 shown Spout, be attached. In this case, however, the training and arrangement can - with appropriate adaptation - be the same as in the previously described cases.

Schliesslich versteht es sich von selbst, dass die zuvor beschriebenen Ausführungsformen nicht nur auf Rohrmühlen beschränkt sind, sondern dass alle Drehtrommeln (wie eingangs erwähnt) in der erläuterten Weise ausgebildet sein können.Finally, it goes without saying that the above-described embodiments are not only limited to tube mills, but that all rotary drums (as mentioned at the beginning) can be designed in the manner explained.
