Description
Die Erfindung betrifft ein Planetengetriebe, insbesondere für einen Pitch- oder Azimutantrieb einer Windenergieanlage, gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a planetary gear, in particular for a Pitch or Azimutantrieb a wind turbine, according to the preamble of claim 1
Azimutantriebe werden für eine Windnachführung einer Gondel und Pitchantriebe werden zur Verstellung von Rotorblättern der Windenergieanlage eingesetzt.Yaw drives be for a wind tracking A gondola and pitch drives are used to adjust the rotor blades of the Wind turbine used.
In dem Merkblatt RD 76111 der Anmelderin sind derartige Planetengetriebe offenbart. Dieses hat eine von einem Elektromotor angetriebene Antriebswelle und eine mit einem Abtriebsritzel verbundene Abtriebswelle. Die An- und Abtriebswellen stehen über mehrere Planetenstufen in Wirkverbindung, wobei jede Planetenstufe mehrere Planetenräder aufweist. Diese sind zwischen einem feststehenden Gehäuse, das als Hohlrad dient, und jeweils einem Sonnenrad angeordnet. Die Lagerung der Planetenräder erfolgt über Wälzlager, die an einem Lagerzapfen fixiert sind, wobei ein jeweiliger Lagerzapfen in einen Planetenradträger eingeschraubt oder eingepresst ist.In the leaflet RD 76111 the applicant are such planetary gear disclosed. This has a driven by an electric motor drive shaft and an output shaft connected to an output pinion. The Input and output shafts are over several planetary stages in operative connection, each planetary stage several planet wheels having. These are between a fixed housing, the serves as a ring gear, and each arranged a sun gear. Warehousing the planetary gears take place via rolling bearings, which are fixed to a journal, wherein a respective journal in a planet carrier screwed or pressed.
Nachteilig bei dieser Lösung ist, dass durch die hohen in einer Windenergieanlage auftretenden wechselnden Belastungen die Lagerzapfen für die Lagerung der Planetenräder vom Planetenradträger ausgeschlagen werden können. Dies führt dann im Normalfall zum Ausfall des Planetengetriebes.adversely in this solution is that changing due to the high occurring in a wind turbine Load the journals for the bearing of the planet gears knocked out by the planet carrier can be. this leads to then normally the failure of the planetary gear.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein Planetengetriebe zu schaffen, das eine hohe Robustheit aufweist.In contrast, lies The invention has for its object to provide a planetary gear, the has a high robustness.
Diese Aufgabe wird gelöst durch ein Planetengetriebe mit den Merkmalen des Patentanspruchs 1.These Task is solved by a planetary gear with the features of claim 1.
Erfindungsgemäß hat ein Planetengetriebe, insbesondere für einen Pitch- oder Azimutantrieb einer Windenergieanlage, eine Antriebs- und eine Abtriebswelle. Diese stehen über zumindest eine Planetenstufe miteinander in Wirkverbindung. Die Planetenstufe weist eine Mehrzahl von Planetenrädern auf, die zwischen einem fixierten Hohlrad und einem von der Antriebswelle angetriebenen Sonnenrad angeordnet sind. Gelagert sind die Planetenräder jeweils auf einem Lagerzapfen eines auf der Abtriebswelle mechanisch fixierten Planetenradträgers. Vorteilhafterweise sind die Lagerzapfen einstückig mit dem Planetenradträger ausgebildet.According to the invention has a Planetary gear, especially for a pitch or azimuth drive of a wind energy plant, a drive and an output shaft. These are about at least one planetary stage in operative connection with each other. The planetary stage has a plurality of planet wheels on, between a fixed ring gear and one of the drive shaft driven sun gear are arranged. The planet wheels are stored on each a journal of a mechanically fixed on the output shaft Planet carrier. Advantageously, the bearing pins are integrally formed with the planet carrier.
Diese Lösung hat den Vorteil, dass ein Lösen der Lagerzapfen, wie im eingangs erläuterten Stand der Technik, durch die einstückige Ausbildung mit dem Planetenradträger in jedem Fall vermieden ist, wodurch ein derartiges Planetengetriebe eine höhere Lebensdauer und eine höhere Robustheit aufweist. Des Weiteren ist ein derartiger Lagerzapfen zusammen mit dem Planetenradträger äußerst kostengünstig herstellbar, da diese aus einem Werkstück geschmiedet werden können und weitere Zusatzbauteile nicht benötigt werden.These solution has the advantage that a release of the Bearing journals, as explained in the introduction State of the art, through the one-piece design with the planet carrier in each Case is avoided, whereby such a planetary gear a longer life and a higher one Robustness. Furthermore, such a journal together with the planet carrier extremely inexpensive to produce, since these are made of a workpiece can be forged and additional components are not needed.
Mit Vorteil sind bei mehreren Planetenstufen alle weiteren Planetenradträger jeweils am Sonnenrad der jeweiligen im Kraftfluss abwärts liegenden, benachbarten Planetenstufe mechanisch fixiert.With Advantage of several planetary stages all other planetary gear respectively on the sun gear of the respective downstream in the power flow, adjacent Planet stage mechanically fixed.
Das eine oder die mehreren Sonnenräder können mit geringem vorrichtungstechnischem Aufwand über ihre Stirnflächen zwischen der An- und Abtriebswelle gleitend gelagert sein.The one or more sun gears can with low device technical effort over their faces between be slidably mounted on the input and output shafts.
Zur Gewichtsreduzierung ist ein jeweiliges Sonnenrad im Wesentlichen hohlzylindrisch ausgebildet.to Weight reduction is essentially a respective sun gear hollow cylindrical.
Bevorzugter Weise sind die Abtriebswelle und die Sonnenräder von dem zugeordneten Planetenradträger formschlüssig umgriffen und mit diesem verbunden. Die Verbindung erfolgt vorzugsweise durch eine Kerbzahnverbindung.preferred Way, the output shaft and the sun gears are positively embraced by the associated planet carrier and connected to it. The connection is preferably carried out by a serrated connection.
Zur Minimierung der Reibung sind die Planetenräder jeweils über ein am jeweiligen Lagerzapfen fixierten Wälzlager gelagert.to Minimizing friction, the planetary gears are each about one stored on each bearing pin fixed bearings.
Um eine hohe Getriebeübersetzung zu erreichen, die besonders feinfühlige Drehbewegungen einer Gondel einer Windenergieanlage ermöglicht, sind vier Planetenstufen bei dem Planetengetriebe vorgesehen.Around a high gear ratio to achieve the most sensitive rotational movements of a Gondola of a wind turbine allows four planetary stages provided at the planetary gear.
Die Planetenradträger und die dazugehörigen Lagerzapfen sind kostengünstig über Gesenkschmieden herstellbar.The planet and the associated ones Bearing journals are inexpensive via die forging produced.
Sonstige vorteilhafte Weiterbildungen der Erfindung sind Gegenstand weiterer Unteransprüche.other advantageous developments of the invention are the subject of further Dependent claims.
Im Folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand einer einzigen schematischen Zeichnung näher erläutert. Diese zeigt in einer Längsschnittansicht ein Planetengetriebe.in the The following will be a preferred embodiment of the invention explained in more detail with reference to a single schematic drawing.
