Description
Die vorliegende Erfindung betrifft ein Vertikalmühlengetriebe, wie diese beispielsweise aus
Vertikalmühlen sind im Stand der Technik in verschiedenen Ausgestaltungen bekannt. Sie dienen zur Zerkleinerung unterschiedlicher Materialien, wie beispielsweise Mineralien, Kalkstein, Braun- und Steinkohle, Zementrohmaterial oder dergleichen. Sie umfassen normalerweise einen rotierenden horizontalen Mahlteller, auf den die in einer Mahlschüssel aufgenommenen Mahlwerkzeuge angepresst werden, und ein unterhalb des Mahltellers angeordnetes Vertikalmühlengetriebe. Die Hauptaufgaben des Vertikalmühlengetriebes bestehen in der Leistungsübertragung, der Übersetzung des erforderlichen Drehmomentes und der erforderlichen Drehzahl, der Lagerung der Mahlschüssel und der Aufnahme der Mahlkräfte.Vertical mills are known in the art in various embodiments. They serve for the comminution of different materials, such as minerals, limestone, brown and hard coal, cement raw material or the like. They usually comprise a rotating horizontal grinding table, on which the grinders received in a grinding bowl are pressed, and a vertical mill gear arranged below the grinding plate. The main tasks of the vertical mill gearbox are the power transmission, the translation of the required torque and the required speed, the storage of the grinding bowl and the recording of grinding forces.
Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, ein Vertikalmühlengetriebe der eingangs genannten Art mit optimiertem Aufbau zu schaffen, das sich insbesondere einfach fertigen und leicht montieren und warten lässt.Starting from this prior art, it is an object of the present invention to provide a vertical mill gear of the type mentioned above with optimized design, especially easy to manufacture and easy to assemble and maintain.
Zur Lösung dieser Aufgabe schafft die vorliegende Erfindung ein Vertikalmühlengetriebe mit einem Gehäuse, das einen lösbar befestigten und im Wesentlichen ringförmig ausgebildeten Gehäusehalteabschnitt aufweist; einem Sonnenrad, das an einer am Gehäuse gelagerten, über einen Motor antreibbaren Sonnenradwelle vorgesehen ist; einem drehbar an dem Gehäusehalteabschnitt gelagerten Planetenträger, an dem zumindest ein Planetenrad drehbar gehalten ist, wobei das Planetenrad mit dem Sonnenrad in Eingriff ist; einem drehfest an dem Gehäuse gehaltenen, eine Innenverzahnung aufweisenden Hohlrad, mit dem das zumindest eine Planetenrad in Eingriff ist, und einem drehfest mit dem Planetenträger verbundenen und an dem Gehäuse gelagerten Abtriebsflansch.To achieve this object, the present invention provides a vertical mill gear with a housing having a releasably secured and substantially annular housing housing portion; a sun gear, which is provided on a housing mounted on the, driven by a motor sun gear shaft; a planetary carrier rotatably mounted on the housing holding portion, on which at least one planetary gear is rotatably supported, wherein the planet gear is in engagement with the sun gear; a rotatably held on the housing, having an internal gear ring gear, with which the at least one planet gear is engaged, and a rotatably connected to the planet carrier and mounted on the housing output flange.
Mit anderen Worten wird die bekannte Drehmomentübertragung zwischen dem Planetenträger und dem Abtriebsflansch mittels Kegelsitz und Kupplungsring erfindungsgemäß durch eine Drehmomentübertragung mittels einer Schraub-Stift-Verbindung ersetzt. Diese konstruktive Änderung zieht mehrere Vorteile nach sich. Zum einen wird die Fertigung sowohl des Abtriebsflansches als auch des Planetenträgers erheblich vereinfacht, da der aufwendig herzustellende Kegelsitz entfällt. Auch die Ausbildung einer Kurzverzahnung am Planetenträger zur Aufnahme des Kupplungsrings entfällt, wodurch bei der Produktion Arbeitsgänge eingespart werden können. Darüber hinaus wird die Anzahl von Bauteilen reduziert, was zu einem einfachen und preiswerten Aufbau beiträgt, der sich leicht montieren lässt.In other words, the known torque transmission between the planetary carrier and the output flange is replaced by means of conical seat and coupling ring according to the invention by a torque transmission by means of a screw-pin connection. This structural change has several advantages. On the one hand, the production of both the output flange and the planet carrier is considerably simplified, since the cost-effectively manufactured conical seat is eliminated. The formation of a short toothing on the planet carrier for receiving the coupling ring is eliminated, which can be saved during production operations. In addition, the number of components is reduced, which contributes to a simple and inexpensive construction that is easy to assemble.
Gemäß einer Ausgestaltung der vorliegenden Erfindung ist der Planetenträger über ein radiales Gleitlager an dem Gehäuse gelagert. Aufgrund der Tatsache, dass erfindungsgemäß die Drehmomentübertragung zwischen dem Planetenträger und dem Abtriebsflansch über eine Schraub-Stift-Verbindung erfolgt, ist es vorteilhaft, den Lochkreisdurchmesser, entlang dem die Schrauben und Stifte zur Erzeugung der Schraub-Stift-Verbindung angeordnet sind, möglichst groß zu wählen. Ein großer Lochkreisdurchmesser ist allerdings dahingehend von Nachteil, dass in radialer Richtung viel Bauraum benötigt wird. Durch die Anordnung eines Gleitlagers anstelle eines Wälzlagers zur Lagerung des Planetenträgers am Gehäuse wird entsprechender Bauraum eingespart, wodurch der durch die Schraub-Stift-Verbindung verursachte zusätzliche Bauraumbedarf in radialer Richtung zumindest teilweise kompensiert wird.According to one embodiment of the present invention, the planet carrier is mounted on the housing via a radial slide bearing. Due to the fact that according to the invention the torque transmission between the planet carrier and the output flange via a screw-pin connection, It is advantageous to choose the pitch circle diameter along which the screws and pins are arranged to produce the screw-pin connection as large as possible. However, a large pitch circle diameter is disadvantageous in that much space is required in the radial direction. By arranging a sliding bearing instead of a rolling bearing for supporting the planet carrier on the housing corresponding space is saved, whereby the caused by the screw-pin connection additional space requirements in the radial direction is at least partially compensated.
Zwischen dem Abtriebsflansch und dem Gehäuse, insbesondere dem Gehäusehalteabschnitt, ist bevorzugt ein Gleitlager vorgesehen, wodurch ein einfacher Aufbau erzielt wird.Between the output flange and the housing, in particular the housing holding portion, a sliding bearing is preferably provided, whereby a simple construction is achieved.
Vorteilhaft weisen der Planetenträger und der Abtriebsflansch miteinander fluchtende Durchgangsöffnungen auf, wobei zumindest ein Deckel zum Verschließen der Durchgangsöffnung des Planetenträgers vorgesehen ist. Mit anderen Worten ist der Planetenträger nach Art einer Hohlwelle ausgebildet. Hierdurch wird zum einen der Vorteil erzielt, dass in Bezug auf den Planetenträger viel Material eingespart werden kann. Zum anderen kann dank der am Abtriebsflansch und am Planetenträger vorgesehenen Durchgangsöffnungen die Sonnenradanordnung nach Öffnen des Deckels inspiziert werden. Dies erlaubt eine sehr einfache Wartung, da hierzu der Abtriebsflansch, der Gehäusehalteabschnitt und der Planetenträger nicht wie bei der eingangs beschriebenen bekannten Konstruktion demontiert werden müssen. Darüber hinaus lässt sich der als Hohlwelle ausgebildete Planetenträger einfach gießen.Advantageously, the planet carrier and the output flange have mutually aligned through openings, wherein at least one cover is provided for closing the passage opening of the planet carrier. In other words, the planet carrier is designed in the manner of a hollow shaft. As a result, on the one hand, the advantage is achieved that with respect to the planet carrier a lot of material can be saved. On the other hand, thanks to the through-openings provided on the output flange and on the planet carrier, the sun gear arrangement can be inspected after the lid has been opened. This allows a very simple maintenance, since this the output flange, the housing holding portion and the planet carrier does not need to be dismantled as in the known structure described above. In addition, the trained as a hollow shaft planet carrier can be easily cast.
Vorteilhaft weisen die Durchgangsöffnungen des Planetenträgers und des Abtriebsflansches einen Öffnungsquerschnitt auf, der derart dimensioniert ist, dass zumindest das Sonnenrad durch diese entnehmbar ist. Entsprechend kann das Sonnenrad in einfacher Art und Weise ausgebaut und repariert bzw. erneuert sowie das Kupplungselement inspiziert werden, ohne dass hierfür aufwendige Demontagearbeiten am Getriebe erforderlich sind.Advantageously, the passage openings of the planet carrier and the output flange have an opening cross-section which is dimensioned such that at least the sun gear can be removed therefrom. Accordingly, the sun gear in a simple manner removed and repaired or renewed and the coupling element to be inspected, without the need for costly disassembly work on the gearbox are required.
Gemäß einer Ausgestaltung der vorliegenden Erfindung ist die Sonnenradwelle über ein Kupplungselement lösbar und drehfest aber einstellbeweglich mit einer Zwischenwelle verbunden, insbesondere über eine Kupplungshülse. Durch diese Anordnung erhält das Sonnenrad das erforderliche Speilt. Darüber hinaus wird die Demontage des Sonnenrads erleichtert.According to one embodiment of the present invention, the sun gear is releasably connected via a coupling element and rotatably but adjustably connected to an intermediate shaft, in particular via a coupling sleeve. By this arrangement, the sun gear receives the required Speilt. In addition, the disassembly of the sun gear is facilitated.
Vorteilhaft ist der Gehäusehalteabschnitt mit Ölrücklaufbohrungen versehen, wodurch eine ordnungsgemäße Schmierung und Kühlung sichergestellt wird.Advantageously, the housing holding portion is provided with oil return holes, whereby a proper lubrication and cooling is ensured.
Vorteilhaft ist der Planetenträger mit Schmiermittelbohrungen zur Versorgung der Planetenradlagerung versehen, was zu einer konstruktiv einfachen und direkten Kühlung und Schmierung der Planetenradlagerung führt.Advantageously, the planet carrier is provided with lubricant bores for supplying the Planetenradlagerung, resulting in a structurally simple and direct cooling and lubrication of Planetenradlagerung.
