Description

Die Erfindung betrifft eine Fräswalze nach dem Oberbegriff des Anspruchs 1, bzw. eine Baumaschine nach Anspruch 24, sowie eine Getriebeeinheit für eine Fräswalze nach Anspruch 25.The invention relates to a milling drum according to the preamble of claim 1, or a construction machine according to claim 24, and a gear unit for a milling drum according to claim 25.

Häufig ist es nötig, aufgrund unterschiedlicher Baustellensituationen und Fräsarbeiten, das Fräswerkzeug einer Straßenfräsmaschine den spezifischen Aufgaben anzupassen. Beispielsweise, wenn eine bestimmte Oberflächenrauhigkeit erreicht werden soll, ist eine Fräswalze mit einem bestimmten Linienabstand der Fräswerkzeuge, oder eine andere Werkzeugausrüstung erforderlich. In einem anderen Anwendungsfall sollen nur bestimmte Fahrbahnbreiten ausgebaut werden, so dass eine Fräswalze mit einer bestimmten Arbeitsbreite benötigt wird.Often it is necessary, due to different construction site situations and milling, to adapt the milling tool of a road milling machine to the specific tasks. For example, if a certain surface roughness is to be achieved, a milling drum with a certain line spacing of the milling tools or other tooling is required. In another application, only certain roadway widths are to be expanded, so that a milling drum with a certain working width is needed.

In der Regel muss in solchen Situationen eine spezielle Fräsmaschine eingesetzt werden, oder die Maschine muss mit einer der Aufgabe angepassten Fräswalze ausgerüstet werden. Gegenwärtig ist der Austausch der Fräswalzen aber sehr aufwändig und erfordert spezielle Hilfsmittel zur Montage bzw. Demontage der Fräswalze.As a rule, a special milling machine must be used in such situations or the machine must be equipped with a milling drum adapted to the task. At the moment, however, the replacement of the milling drums is very complicated and requires special aids for mounting or dismounting the milling drum.

Aus der EP 1194651 B und der EP 1520076 B sind Fräswalzen für Straßenfräsen oder Recycler bekannt, bei denen die Fräswalze ein auswechselbares Fräsrohr aufweist, wobei die Achse des Fräsrohrs, mit Hilfe eines Stützrings, auf einer Stützringaufnahme eines drehbar gelagerten, mit einem Fräswalzenantrieb gekoppelten Körpers abgestützt ist. Der Stützring sitzt mit einem vorbestimmten Spiel auf der Stützringaufnahme, wobei in den Spalt zwischen Stützring und Stützringaufnahme Schmutzwasser, Staub und feinkörnige Teile der Straßenoberfläche eindringen können, insbesondere aufgrund von Relativbewegungen zwischen dem Stützring und der Stützringaufnahme, die aus dem Fräsprozess herrühren. Die Kapillarwirkung der Spielpassung verstärkt diesen Effekt, so dass verschmutztes Wasser und feinkörnige Partikel in die Passung eindringen.From the EP 1194651 B and the EP 1520076 B are known milling wheels for road milling or recycler, wherein the milling drum has a replaceable milling tube, wherein the axis of the milling tube, supported by a support ring on a support ring receptacle of a rotatably mounted, coupled with a milling drum drive body. The support ring is seated with a predetermined play on the support ring receptacle, wherein in the gap between the support ring and support ring receiving dirty water, dust and fine-grained parts of the road surface can penetrate, in particular due to relative movements between the support ring and the support ring receiving, resulting from the milling process. The capillary action of the clearance increases this effect, so that contaminated water and fine particles penetrate into the fit.

Wenn zu Demontagezwecken das Fräsrohr mit dem Stützring von der Stützringaufnahme abgezogen werden soll, ist dies oft nur sehr schwer oder gar nicht möglich.If, for disassembly purposes, the milling tube with the support ring is to be removed from the support ring receptacle, this is often very difficult or even impossible.

Bei den gegebenen Abmessungen, nämlich bei einem im Verhältnis zum Fräswalzendurchmesser in Axialrichtung kurzen Stützring, ist die Demontage nicht einfach, wobei sich allerdings auch die Montage im gereinigten Zustand durch Verkanten schwierig gestalten kann.With the given dimensions, namely at a short in relation to the Fräswalzendurchmesser in the axial direction support ring disassembly is not easy, but also the assembly in the cleaned state by tilting can make difficult.

Auch konisch gestaltete Stützflächen haben sich nicht als praktikabel erwiesen, weil sie sich einerseits zu stark festsetzen können und andererseits ein zu großes radiales Spiel aufweisen, wenn die aufzuschiebende Fräswalze zu kurz ist. Bei einer konischen Stützfläche wäre daher eine Genauigkeit der Positionierung des konischen Stützringes und der Stützringaufnahme in einem Bereich von +/- 1 mm erforderlich, um eine Funktion überhaupt zu ermöglichen, wobei das Problem, dass sich eine Konusverbindung festfressen kann, bestehen bleibt.Also, conically shaped support surfaces have not proven to be practical, because on the one hand they can set too strong and on the other hand have too much radial play when the aufzuschiebende milling roller is too short. Therefore, with a conical support surface, accuracy of positioning the conical support ring and the support ring receptacle in a range of +/- 1 mm would be required to enable operation at all, while still maintaining the problem that a cone joint may seize.

Der Erfindung liegt daher die Aufgabe zugrunde, bei Fräswalzen mit auswechselbaren Fräsrohren, bei Baumaschinen mit Fräswalzen und bei Getriebeeinheiten, die eine Fräswalze antreiben, die Montage und Demontage des Fräsrohrs zu vereinfachen.The invention is therefore based on the object of simplifying the assembly and disassembly of the milling tube in milling drums with replaceable milling tubes, in construction machines with milling drums and gear units that drive a milling drum.

Zur Lösung dieser Aufgabe dienen die Merkmale der Ansprüche 1, 24 und 25.To achieve this object, the features of claims 1, 24 and 25 serve.

Die Erfindung sieht in vorteilhafter Weise vor, dass der Stützring und die Stützringaufnahme des drehbar gelagerten Körpers mehrere zur Fräswalzenachse konzentrisch verlaufende, einander komplementäre Stützflächen mit unterschiedlichen Stützkreisdurchmessern aufweisen, die axial hintereinander mit in Abzugsrichtung abnehmenden Durchmessern gestuft angeordnet sind.The invention provides in an advantageous manner that the support ring and the support ring receptacle of the rotatably mounted body a plurality of Fräswalzenachse concentrically extending, complementary support surfaces having different Stützkreisdurchmessern which are arranged axially one after another with decreasing diameters in the withdrawal direction.

Durch die treppenförmige Gestaltung der Stützflächen des Stützrings und der Stützringaufnahme kann ohne Reduzierung der Gesamtfläche der Stützfläche erreicht werden, dass das Fräsrohr nur um den Betrag der Breite einer Stufe abgezogen werden muss, um den Stützring außer Eingriff mit der Stützringaufnahme zu bringen. Beispielsweise kann bei einer fünffachen Abstufung der Weg der erforderlich ist um die Stützflächen voneinander zu trennen, auf ein Fünftel der gesamten axialen Länge der Stützfläche reduziert werden.Due to the step-shaped design of the support surfaces of the support ring and the support ring receiving can be achieved without reducing the total surface area of the support surface, that the milling tube must be deducted only by the amount of width of a step to bring the support ring out of engagement with the support ring receptacle. For example, with a five-fold gradation, the distance required to separate the support surfaces from each other can be reduced to one-fifth of the total axial length of the support surface.

Besonders vorteilhaft ist dabei, dass die wirksame Stützfläche für das Fräsrohr nahezu unverändert bleibt.It is particularly advantageous that the effective support surface for the milling tube remains virtually unchanged.

Bei einem bevorzugten Ausführungsbeispiel sind mindestens drei, vorzugsweise fünf Stützflächen axial hintereinander angeordnet.In a preferred embodiment, at least three, preferably five support surfaces are arranged axially one behind the other.

Die Länge der axial hintereinander angeordneten Stützflächen beträgt 5 bis 40 mm, vorzugsweise 10 bis 20 mm. Auf diese Weise wird eine tragfähige Stützfläche für ein Fräsrohr einer Fräswalze geschaffen.The length of the axially successively arranged support surfaces is 5 to 40 mm, preferably 10 to 20 mm. In this way, a load bearing support surface for a milling tube of a milling drum is created.

Die Länge einer Stützfläche kann in Axialrichtung gleich sein. Dies hat den Vorteil, dass beim Abziehen alle Stützflächen gleichzeitig außer Eingriff sind.The length of a support surface may be the same in the axial direction. This has the advantage that when removing all support surfaces are simultaneously disengaged.

Alternativ kann auch die Länge der Stützflächen in Axialrichtung unterschiedlich sein und zwar vorzugsweise derart, dass die Länge der Stützflächen mit abnehmenden Stützkreisdurchmesser abnimmt. Dies hat den Vorteil, dass die Stützflächen, insbesondere bei der Montage, nicht alle gleichzeitig im Eingriff sind, wodurch die Montage erleichtert werden kann.Alternatively, the length of the support surfaces in the axial direction may be different, and preferably such that the length of the support surfaces decreases with decreasing support circle diameter. This has the advantage that the support surfaces, in particular during assembly, are not all engaged at the same time, whereby the assembly can be facilitated.

Nach einem weiteren vorteilhaften Ausführungsbeispiel ist vorgesehen, dass die Stützflächen des Stützringes gegenüber der Stützflächen der Stützringaufnahme axial in Abzugsrichtung des Fräsrohres versetzt sind, derart, dass an den Stufenübergängen Ringkammern gebildet sind.According to a further advantageous embodiment, it is provided that the support surfaces of the support ring relative to the support surfaces of the support ring receiving axially offset in the withdrawal direction of the milling tube, such that annular chambers are formed at the step transitions.

Die Ringkammern können in vorteilhafter Weise dazu benutzt werden, mit einem Korrosionsschutzmittel oder einem Schmiermittel gefüllt zu werden.The annular chambers can be used advantageously to be filled with a corrosion inhibitor or a lubricant.

Hierzu können die Ringkammern mit einem Einspritzkanal verbunden sein, über den ein Korrosionsschutzmittel und/oder ein Schmiermittel einspritzbar ist. Beispielsweise kann der Einspritzkanal einen Nippel zum Einspritzen von Fett aufweisen.For this purpose, the annular chambers may be connected to an injection channel, via which a corrosion protection agent and / or a lubricant can be injected. For example, the injection channel may have a nipple for injecting grease.

Die Stützflächen können mit einer Gleitschicht beschichtet sein, um die Montage und Demontage zu erleichtern.The support surfaces may be coated with a sliding layer to facilitate assembly and disassembly.

Die Stützringaufnahme kann aus einem einteiligen Ring bestehen oder auch einstückig mit dem drehbar gelagerten Körper sein. Die einteilige Stützringaufnahme kann beispielsweise auf den drehbar gelagerten Körper aufgeschoben werden und dort axial fixiert werden.The support ring receptacle may consist of a one-piece ring or be integral with the rotatably mounted body. The one-piece support ring receptacle can be pushed, for example, on the rotatably mounted body and fixed there axially.

Alternativ kann die Stützringaufnahme einstückig mit dem drehbar gelagerten Körper sein, wodurch die Anzahl der Bauteile reduziert werden kann.Alternatively, the support ring receiver can be integral with the rotatably mounted body, whereby the number of components can be reduced.

Nach einer Alternative ist vorgesehen, dass die Stützringaufnahme aus einem mehrteiligen, vorzugsweise zweiteiligen Ring besteht, der auf dem drehbar gelagerten Körper montierbar ist. Eine derartige Stützringaufnahme ist vorteilhaft, wenn eine Stützringaufnahme nicht auf den drehbar gelagerten Körper aufschiebbar ist.According to an alternative, it is provided that the support ring receptacle consists of a multi-part, preferably two-part ring which can be mounted on the rotatably mounted body. Such a support ring receptacle is advantageous if a support ring receptacle is not pushed onto the rotatably mounted body.

Die Stützringaufnahme ist axial unbeweglich auf dem drehbar gelagerten Körper montiert und bildet ein Los-Lager. Die Stützringaufnahme kann axial an unterschiedlichen Stellen auf dem drehbar gelagerten Körper fixiert sein.The support ring receptacle is axially immovably mounted on the rotatably mounted body and forms a loose bearing. The support ring receptacle can be fixed axially at different locations on the rotatably mounted body.

Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der drehbar gelagerte Körper ein Walzengrundkörper zum Abstützen des Fräsrohres und/oder ein Abtriebsgehäuse einer Getriebeeinheit des Fräswalzenantriebs ist.According to an advantageous embodiment of the invention, it is provided that the rotatably mounted body is a roller base body for supporting the milling tube and / or a driven housing of a gear unit of the milling roller drive.

Die Achse des Fräsrohres kann bei einer zweiseitigen Lagerung einerseits in einer entfernbaren Seitenwand gelagert sein und andererseits sich mit Hilfe des Stützrings auf der Stützringaufnahme des drehbar gelagerten Körpers abstützen, wobei das Fräsrohr nach dem Entfernen der Seitenwand von der Stützringaufnahme des drehbar gelagerten Körpers in Abzugsrichtung abziehbar ist.The axis of the milling tube can be stored in a two-sided storage on the one hand in a removable side wall and on the other hand supported by means of the support ring on the support ring receptacle of the rotatably mounted body, wherein the milling tube after removal of the side wall of the support ring receptacle of the rotatably mounted body in the withdrawal direction deductible is.

Bei einer vorteilhaften Weiterbildung ist vorgesehen, dass der Walzengrundkörper mit dem Fräswalzenantrieb gekoppelt ist und das der Seitenwand zugewandte Ende des Fräsrohres abstützt.In an advantageous development, it is provided that the roller base body is coupled to the milling drum drive and supports the side wall facing the end of the milling tube.

Bei einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass an dem Fräsrohr oder an dem drehbar gelagerten Körper eine Abdrückeinrichtung angreift, mit der das Fräsrohr in Abzugsrichtung von der gelagerten Position zur Demontage abziehbar ist. Dabei kann die Abdrückeinrichtung mechanisch oder hydraulisch vorgesehen sein.In a further advantageous embodiment of the invention it is provided that acts on the milling tube or on the rotatably mounted body a Abdrückeinrichtung with which the milling tube in the withdrawal direction from the stored position for disassembly is removable. In this case, the Abdrückeinrichtung can be provided mechanically or hydraulically.

Des Weiteren ist in besonders vorteilhafter Weise vorgesehen, dass die axialen hintereinander angeordneten Stützflächen mit unterschiedlichem Stützkreisdurchmesser an den Stufenübergängen eine beispielsweise unter 45° verlaufende Fase aufweisen. Diese Fase ermöglicht es, bei der Montage das Fräsrohr leichter zu zentrieren, wodurch die Montage vereinfacht wird. Vorzugsweise wird eine unter 45° verlaufende Fase verwendet.Furthermore, it is provided in a particularly advantageous manner that the axial support surfaces arranged one behind the other with different support circle diameter at the step transitions have a chamfer running, for example, at 45 °. This chamfer makes it easier to center the milling tube during assembly, which simplifies assembly. Preferably, a bevel running at 45 ° is used.

In Fig. 1 ist eine Straßenbaumaschine 1 dargestellt, in der ein Fräsrohr-Schnellwechselsystem eingesetzt werden kann.In Fig. 1 a road construction machine 1 is shown, in which a milling tube quick-change system can be used.

Die Straßenbaumaschine ist eine Straßenfräse, die im allgemeinen einen Maschinenrahmen aufweist, auf dem ein Verbrennungsmotor und ein Fahrstand montiert ist. Die selbstfahrende Straßenbaumaschine weist höhenverstellbare, an dem Maschinenrahmen befestigte Hubsäulen auf, an denen Stützräder oder Kettenlaufwerke montiert sind.The road construction machine is a road milling machine which generally has a machine frame on which an engine and a control station are mounted. The self-propelled road construction machine has height-adjustable, mounted on the machine frame lifting columns on which support wheels or crawler tracks are mounted.

Die Fräswalze 2 befindet sich unter dem Maschinenrahmen in einem Walzenkasten 9, der seitlich die Seitenwänden 13, 15 aufweist. Mit dem Bezugszeichen 7 ist die Schnittkontur der auf der Fräswalze 2 befindlichen Werkzeuge angedeutet. Das von der Fräswalze 2 abgearbeitete Material wird in an sich bekannter Weise auf ein erstes Förderband abgeworfen oder auf ein zweites, höhenverstellbares und schwenkbares Förderband weiterbefördert.The milling drum 2 is located under the machine frame in a roller box 9, which laterally has the side walls 13, 15. By the reference numeral 7, the sectional contour of the tools located on the milling drum 2 is indicated. The processed from the milling drum 2 material is dropped in a conventional manner on a first conveyor belt or conveyed to a second, height-adjustable and pivotable conveyor belt.

In Fig. 2 ist eine Fräswalze 2 drehbar zwischen orthogonal zur Achse 20 der Fräswalze 2 verlaufenden Seitenwänden 13, 15 des Walzenkastens 9 gelagert und wird über eine an der antriebsseitigen Seitenwand 13 gelagerte Antriebseinrichtung 16 und eine Getriebeeinheit 17, angetrieben. Die in Fig. 2 dargestellte Fräswalze 2 besteht aus einem einstückigen Fräsrohr 4, das auswechselbar an einem Walzengrundkörper 19 befestigt ist. Der Walzengrundkörper 19 ist seinerseits an dem Abtriebsgehäuse 21 der Getriebeeinheit 17 befestigt. Der Walzengrundkörper 19 ist axial neben dem Antriebsgehäuse 21 angeordnet und überträgt das Drehmoment der Getriebeeinheit 17 in der Art eines Untersetzungsgetriebes auf das jeweils eingesetzte Fräsrohr 4.In Fig. 2 is a milling drum 2 rotatably mounted between orthogonal to the axis 20 of the milling drum 2 extending side walls 13, 15 of the roller box 9 and is driven by a mounted on the drive side side wall 13 drive means 16 and a gear unit 17, driven. In the Fig. 2 illustrated milling drum 2 consists of a one-piece milling tube 4, which is removably attached to a roller body 19. The roller body 19 is in turn attached to the output housing 21 of the transmission unit 17. The roller main body 19 is arranged axially next to the drive housing 21 and transmits the torque of the gear unit 17 in the manner of a reduction gear to the respective inserted milling tube 4th

Der Fräswalzenantrieb 16 besteht vorzugsweise aus einem Riementrieb.The milling drum drive 16 preferably consists of a belt drive.

Das Fräsrohr ist in Fig. 2 über einen Ringflansch 23 an den Walzengrundkörper 19 angeschraubt, der seinerseits drehbar in der entfernbaren Seitenwand 15 gelagert ist. Auf der dem Fräswalzenantrieb 16 zugewandten Seite des Fräsrohrs 4 ist ein drehfest mit dem Fräsrohr 4 verbundener Stützring 8 angeordnet, der mit einer auf dem Abtriebsgehäuse 21 sitzende Stützringaufnahme 12 kooperiert.The milling tube is in Fig. 2 screwed via an annular flange 23 to the roller body 19, which in turn is rotatably mounted in the removable side wall 15. On the milling drum drive 16 facing side of the milling tube 4 a rotatably connected to the milling tube 4 support ring 8 is arranged, which cooperates with a seated on the output housing 21 support ring receptacle 12.

Der Stützring 8 und die Stützringaufnahme 12 weisen mehrere zur Fräswalzenachse 20 konzentrisch verlaufende einander komplementäre Stützflächen 22, 24 mit unterschiedlichen Stützkreisdurchmessern auf, die axial hintereinander mit in Richtung der Seitenwand 15 abnehmenden Durchmesser gestuft angeordnet sind. In dem Ausführungsbeispielen sind beispielsweise fünf Stützflächen axial hintereinander angeordnet. Die axiale Länge der Stützflächen 22, 24 beträgt in den dargestellten Ausführungsbeispielen 15 mm, kann allerdings je nach Durchmesser der Fräswalze 2 zwischen 5 und 40 mm, vorzugsweise zwischen 10 und 20 mm variieren.The support ring 8 and the support ring receptacle 12 have a plurality of mutually complementary to Fräswalzenachse 20 mutually complementary support surfaces 22, 24 with different Stützkreisdurchmessern, which are arranged axially one after another with decreasing in the direction of the side wall 15 diameter. In the exemplary embodiments, for example, five support surfaces are arranged axially one behind the other. The axial length of the support surfaces 22, 24 is 15 mm in the illustrated embodiments, but may vary depending on the diameter of the milling drum 2 between 5 and 40 mm, preferably between 10 and 20 mm.

Die Ausführungsbeispiele zeigen, dass die axiale Länge aller Stützflächen 22, 24 gleich ist. Sie können allerdings auch eine unterschiedliche Länge aufweisen, und zwar vorzugsweise derart, dass die Länge der Stützflächen 22, 24 mit abnehmendem Stützkreisdurchmesser abnimmt.The exemplary embodiments show that the axial length of all supporting surfaces 22, 24 is the same. However, they may also have a different length, and preferably such that the length of the support surfaces 22, 24 decreases with decreasing Stützkreisdurchmesser.

Wie am besten aus den Fign. 3 und 4 ersichtlich wird, sind die Stützflächen 22 des Stützringes 8 gegenüber den Stützflächen 24 der Stützringaufnahme 12 axial in Richtung der Seitenwand 15 versetzt, derart, dass an den Stufenübergängen Ringkammern 25 gebildet sind. Die Ringkammern 25 können mit einem Korrosionsschutzmittel und/oder einem Schmiermittel gefüllt werden. Wie aus Fig. 4 ersichtlich, kann ein Einspritzkanal 26 vorgesehen sein, über den, wie aus Fig. 3 ersichtlich, mindestens drei Ringkammern 25 z.B. mit Fett über einen Schmiernippel 28 versorgen werden können.How best of the FIGS. 3 and 4 it can be seen, the support surfaces 22 of the support ring 8 relative to the support surfaces 24 of the support ring receptacle 12 axially offset in the direction of the side wall 15, such that annular chambers 25 are formed at the step transitions. The annular chambers 25 may be filled with a corrosion inhibitor and / or a lubricant. How out Fig. 4 As can be seen, an injection channel 26 may be provided over which, as shown Fig. 3 it can be seen, at least three annular chambers 25 can be supplied with grease via a grease nipple 28, for example.

Die Stützflächen 22, 24 können mit einer Gleitschicht zur Erleichterung der Montage und Demontage des Fräsrohrs 4 beschichtet sein.The support surfaces 22, 24 may be coated with a sliding layer to facilitate the assembly and disassembly of the milling tube 4.

Die Stützringaufnahme 12 kann aus einem einteiligen Ring, wie aus Fig. 2 ersichtlich bestehen, oder kann auch einstückig mit dem Abtriebsgehäuse 21 der Getriebeeinheit 17 sein, wie aus den Ausführungsbeispielen der Fign. 9 und 10 hervorgeht.The support ring receptacle 12 may consist of a one-piece ring, as shown Fig. 2 be seen, or may also be integral with the output housing 21 of the gear unit 17, as from the embodiments of FIGS. 9 and 10 evident.

Alternativ kann, wie aus den Fign. 5 und 6 ersichtlich ist, die Stützringaufnahme 12 aus einem mehrteiligen, in den Figuren 5 und 6 zweiteiligen Ring bestehen, der auf einem drehbar gelagerten Körper, z.B. das Abtriebsgehäuse 21 der Getriebeeinheit 17 montierbar ist.Alternatively, as from the FIGS. 5 and 6 it can be seen, the support ring receptacle 12 of a multi-part, in the FIGS. 5 and 6 consist of two-part ring, which is mounted on a rotatably mounted body, such as the output housing 21 of the transmission unit 17.

Dabei kann die Stützringaufnahme 12 auch axial beweglich auf einen drehbar gelagerten Körper montiert sein, wie es in den Ausführungsbeispielen der Fign. 2 bis 4 möglich ist, oder axial unbeweglich auf dem drehbar gelagerten Körper montiert sein, wie aus den Ausführungsbeispielen der Fign. 9 und 10 hervorgeht.In this case, the support ring receptacle 12 may also be axially movably mounted on a rotatably mounted body, as in the embodiments of the FIGS. 2 to 4 is possible, or axially immovably mounted on the rotatably mounted body, as from the embodiments of FIGS. 9 and 10 evident.

In Fig. 5 sind Befestigungsschrauben 14 ersichtlich, mit denen die Stützringaufnahme 12 auf einen drehbar gelagerten Körper montierbar ist. Es versteht sich, dass der drehbare Körper auch aus einem Ring- oder Anschlussflansch bestehen kann und nicht zwingend ein Abtriebsgehäuse 21 oder ein Walzengrundkörper 19 sein muss.In Fig. 5 are fastening screws 14 can be seen, with which the support ring receptacle 12 is mounted on a rotatably mounted body. It is understood that the rotatable body can also consist of a ring or connection flange and not necessarily an output housing 21 or a roller base 19 must be.

Fig. 6 ist ein Schnitt entlang der Linie VI-VI in Fig. 5, wobei der Schnittverlauf durch den Einspritzkanal 26 verläuft. Fig. 6 is a section along the line VI-VI in Fig. 5 , wherein the cutting path passes through the injection channel 26.

Fig. 8 zeigt eine Seitenansicht der Stützringaufnahme 12, entlang der Linie VIII-VIII in Fig. 5. Fig. 8 shows a side view of the support ring receptacle 12, taken along the line VIII-VIII in Fig. 5 ,

In Fig. 7 ist eine mechanische Abdrückeinrichtung 29 gezeigt, bei der mit Hilfe von Schrauben 30 das Fräsrohr 4 von seiner Lagerung auf der Stützringaufnahme abgezogen werden kann.In Fig. 7 a mechanical Abdrückeinrichtung 29 is shown in which by means of screws 30, the milling tube 4 can be deducted from its storage on the support ring receptacle.

Hierzu werden die Schrauben 30 gegen den Befestigungsflansch 23 geschraubt, wodurch das Fräsrohr 4 der Fräswalze 2 abgezogen werden kann.For this purpose, the screws 30 are screwed against the mounting flange 23, whereby the milling tube 4 of the milling drum 2 can be deducted.

Aus Fig. 8 ist auch ersichtlich, dass zwischen den Stützflächen 24 der Stützringaufnahme 12 an den Stufenübergängen jeweils eine unter 45° verlaufende Fase 32 vorgesehen ist, die das Montieren und Zentrieren des Fräsrohres 4 erleichtert. Entsprechende Fasen 32 sind zwischen den Stützflächen 22 des Stützrings 8 ebenfalls vorgesehen.Out Fig. 8 It can also be seen that between the support surfaces 24 of the support ring receptacle 12 at the step transitions in each case a 45 ° extending chamfer 32 is provided which facilitates the mounting and centering of the milling tube 4. Corresponding chamfers 32 are also provided between the support surfaces 22 of the support ring 8.

Die Stützflächen 22, 24 verlaufen konzentrisch zu der Fräswalzenachse 20, vorzugsweise koaxial. Die Höhe einer Stufe zwischen den Stützflächen 22, 24 beträgt beispielsweise 1 bis 4 mm, wobei ein Stufensprung von 2 mm sich als besonders vorteilhaft erwiesen hat.The support surfaces 22, 24 are concentric with the Fräswalzenachse 20, preferably coaxially. The height of a step between the support surfaces 22, 24 is for example 1 to 4 mm, wherein a step jump of 2 mm has proven to be particularly advantageous.
