Description

Aufhängevorrichtung für ein Getriebe Suspension device for a transmission
Die Erfindung betrifft ein Getriebe nach dem Oberbegriff von Anspruch 1. The invention relates to a transmission according to the preamble of claim 1.
Großgetriebe, etwa Getriebe von Windkraftanlagen, müssen aufgrund ihrer Masse mit einem Kran bewegt werden. Dazu weisen aus dem Stand der Technik bekannte Getriebe Ösen auf, die in das Getriebegehäuse eingegossen sind. Die Ösen können entweder direkt an einen Kranhaken angehängt werden, oder es sind Haken zum Einschrauben in die Ösen vorgesehen. Derartige Lösungen sind von Nachteil, da sie den Guss des Getriebegehäuses verkomplizieren und entsprechend teuer machen. Large gears, such as gears for wind turbines, must be moved with a crane due to their mass. For this purpose, gearboxes known from the prior art have eyelets which are cast into the gearbox housing. The eyelets can either be attached directly to a crane hook or hooks can be screwed into the eyelets. Such solutions are disadvantageous because they complicate the casting of the transmission housing and make them correspondingly expensive.
Der Erfindung liegt die Aufgabe zugrunde, ein Getriebe verfügbar zu machen, das die den aus dem Stand der Technik bekannten Lösungen innewohnenden Nachteile nicht aufweist. Insbesondere soll die Fertigung eines Getriebes, das Vorrichtungen zur Handhabung mittels eines Krans aufweist, vereinfacht werden. The invention is based on the object of making available a transmission which does not have the disadvantages inherent in the solutions known from the prior art. In particular, the manufacture of a transmission which has devices for handling by means of a crane is to be simplified.
Diese Aufgabe wird gelöst durch ein Getriebe nach Anspruch 1 . Bevorzugte Weiter bildungen sind in den Unteransprüchen enthalten. This object is achieved by a transmission according to claim 1. Preferred further developments are contained in the subclaims.
Das Getriebe weist ein Gehäuse auf. Dieses ist mit einem ersten und einem zweiten Loch versehen. Das erste Loch weist eine erste Mündung auf, das zweite Loch ent sprechend eine zweite Mündung. Bevorzugt weisen das erste Loch und das zweite Loch jeweils genau eine Mündung auf. The gearbox has a housing. This is provided with a first and a second hole. The first hole has a first mouth, the second hole accordingly a second mouth. The first hole and the second hole preferably each have exactly one mouth.
Das erste Loch und das zweite Loch sind bevorzugt zylindrisch ausgestaltet. Vor zugseise handelt es sich bei dem ersten Loch und dem zweiten Loch um Bohrungen. Eine Bohrung ist ein durch Bohren hergestelltes Loch oder ein Loch, das abweichend hergestellt wurde, aber die gleiche Form hat. Demnach handelt es sich bei einer Boh rung um ein Loch mit der Grundform eines geraden Kreiszylinders. The first hole and the second hole are preferably cylindrical. The first hole and the second hole are holes before pulling. A hole is a hole made by drilling or a hole that is made differently but has the same shape. Accordingly, a hole is a hole with the basic shape of a straight circular cylinder.
Die erste Mündung und die zweite Mündung befinden sich außerhalb des Gehäuses. Das Gehäuse umschließt einen Hohlraum - das Innere des Gehäuses. Es kapselt das Innere gegenüber dem umgebenden Raum. Das erste Loch Loch mündet mit der ersten Mündung, das zweite Loch mit der zweiten Mündung in den umgebenden Raum. The first mouth and the second mouth are outside the housing. The housing encloses a cavity - the inside of the housing. It encapsulates the inside in relation to the surrounding space. The first hole opens with the first mouth, the second hole with the second mouth in the surrounding space.
Erfindungsgemäß ist ein Stab bzw. eine Stange vorgesehen, der durch die erste Mündung in das erste Loch und durch die zweite Mündung in das zweite Loch ein greift. Da die erste Mündung und die zweite Mündung sich außerhalb des Gehäuses befinden, befindet sich auch der Stab außerhalb des Gehäuses. According to the invention, a rod or a rod is provided which engages through the first mouth in the first hole and through the second mouth in the second hole. Since the first mouth and the second mouth are outside the housing, the rod is also outside the housing.
Mit dem Stab lässt sich das Getriebe an einen Kranhaken anhängen. Sowohl der Stab als auch die beiden Löcher lassen sich vergleichsweise einfach und kosten günstig fertigen. The gear can be attached to a crane hook using the rod. Both the rod and the two holes are comparatively simple and inexpensive to manufacture.
In einer bevorzugten Weiterbildung ist das Gehäuse mindestens zweistückig ausge führt, weist also ein erstes Stück und ein zweites Stück auf. Das erste Stück und das zweite Stück sind nicht einstückig miteinander verbunden. Es handelt sich also um Stücke, die physisch separat voneinander ausgeführt sind. In a preferred development, the housing is made at least in two pieces, ie has a first piece and a second piece. The first piece and the second piece are not connected to one another in one piece. These are pieces that are physically separate from each other.
Das erste Stück weist die das erste Loch auf, das zweite Stück das zweite Loch. The first piece has the first hole, the second piece the second hole.
Bei der Montage des Gehäuses wird der Stab in das erste Loch oder in das zweite Loch eingesetzt, bevor die Stücke des Gehäuses miteinander gefügt werden. Beim Fügen wird der Stab in das verbleibende Loch eingeführt. Anschließend ist der Stab formschlüssig in dem ersten Loch und in dem zweiten Loch fixiert. When assembling the housing, the rod is inserted into the first hole or the second hole before the pieces of the housing are joined together. When joining, the rod is inserted into the remaining hole. The rod is then positively fixed in the first hole and in the second hole.
Bevorzugt ist das Getriebe mit einem Hohlrad weitergebildet. Dieses ist Teil einer Planetenstufe, die darüber hinaus einen Planetenträger, Planetenräder und ein Son nenrad aufweist. Die Planetenräder sind drehbar in dem Planetenträger gelagert und kämmen mit dem Hohlrad und/oder dem Sonnenrad. The transmission is preferably developed with a ring gear. This is part of a planetary stage, which also has a planet carrier, planet gears and a sun gear. The planet gears are rotatably mounted in the planet carrier and mesh with the ring gear and / or the sun gear.
Ein Hohlrad bildet in einer bevorzugten Weiterbildung ein drittes Stück des Gehäu ses. Das Hohlrad ist zwischen dem ersten Stück und dem zweiten Stück angeordnet und verbindet die beiden Stücke entsprechend miteinander. Die Fügeverbindung zwi schen dem ersten Stück und dem zweiten Stück kommt über das Hohlrad zustande. So ist das Hohlrad einerseits mit dem ersten Stück gefügt und andererseits mit dem zweiten Stück. Da das erste Stück das erste Loch und das zweite Stück das zweite Loch aufweist, überspannt der Stab das Hohlrad. In a preferred development, a ring gear forms a third piece of the housing. The ring gear is arranged between the first piece and the second piece and connects the two pieces accordingly. The joint between the first piece and the second piece comes about via the ring gear. The ring gear is joined on the one hand to the first piece and on the other hand to the second piece. Since the first piece has the first hole and the second piece has the second hole, the rod spans the ring gear.
Zwischen den zwei Mündungen der Löcher verläuft in einer darüber hinaus bevor zugten Weiterbildung ein Spalt bzw. ein Zwischenraum. Die Mündungen sind ent sprechend voneinander beabstandet. Ist das weiterbildungsgemäße Hohlrad vorhan den, so befindet sich das Hohlrad in dem Zwischenraum. Der Zwischenraum ermög licht es, ein Mittel zum Anhängen des Getriebes, etwa einen Kranhaken oder ein Seil, einzuführen und an dem Stab zu befestigen. In a further preferred training, a gap or space runs between the two mouths of the holes. The mouths are spaced accordingly. If the ring gear in accordance with further training is present, the ring gear is located in the intermediate space. The space enables a means for attaching the gear, such as a crane hook or a rope, to be inserted and fastened to the rod.
Bevorzugt sind die Mündungen so weitergebildet, dass sie aufeinander zu gerichtet sind. Insbesondere können die Löcher fluchten. The orifices are preferably further developed such that they are directed towards one another. In particular, the holes can be aligned.
Der Stab weist in einer bevorzugten Weiterbildung drei Abschnitte auf. Die Abschnitte sind längs des Stabs angeordnet und durch Querschnittsflächen voneinander ge trennt. Ein erster Abschnitt greift in das erste Loch ein, ein zweiter Abschnitt in das zweite Loch. Der dritte Abschnitt verläuft zwischen dem ersten Abschnitt und dem zweiten Abschnitt und verbindet diese Abschnitte miteinander. In a preferred development, the rod has three sections. The sections are arranged along the rod and separated from one another by cross-sectional areas. A first section engages in the first hole, a second section in the second hole. The third section runs between the first section and the second section and connects these sections to one another.
Da der erste Abschnitt und der zweite Abschnitt jeweils in eins der Löcher eingreifen, sind diese Abschnitte bevorzugt zylindrisch ausgeführt. Der erste Abschnitt und der zweite Abschnitt haben also die Form geraden eines Zylinders, bevorzugt eines gera den Kreiszylinders. Since the first section and the second section each engage in one of the holes, these sections are preferably cylindrical. The first section and the second section thus have the shape of a straight cylinder, preferably a straight cylinder.
Der dritte Abschnitt kann gerade oder gebogen ausgeführt sein. Ein gebogener Ver lauf, bei dem eine Mittellinie des dritten Abschnitts den Verlauf einer gekrümmten Kurve beschreibt, schafft Platz zum Einführen des Mittels zum Anhängen des Getrie bes schafft. The third section can be straight or curved. A curved Ver course, in which a center line of the third section describes the course of a curved curve, creates space for introducing the means for attaching the gearbox bes.
Ein gerader Verlauf des dritten Abschnitts, bei dem der dritte Abschnitt und folglich der gesamte Stab zylindrisch ausgeführt sind, ermöglicht es, den Stab in dem Ge- häuse zu Verschieben. In diesem Fall sind das erste Loch und das zweite Loch be vorzugt durchgehend. Durch Verschieben des Stabs kann der Stab in eine geschlos sene Schlaufe eingefädelt werden. A straight course of the third section, in which the third section and consequently the entire rod are cylindrical, enables the rod to be Move house. In this case, the first hole and the second hole are preferably continuous. By moving the rod, the rod can be threaded into a closed loop.
