Gebiet der ErfindungField of the invention
Die vorliegende Erfindung betrifft einen Planetenträger für ein Planetengetriebe und ein Verfahren zur Herstellung eines Planetenträgers.The present invention relates to a planet carrier for a planetary gear and a method for producing a planet carrier.
Hintergrund der ErfindungBackground of the invention
Planetengetriebe sind im Stand der Technik allgemein bekannt. Zum einen kann durch sie eine Übersetzung und eine Momentenübertragung von einer Antriebswelle auf eine Abtriebswelle realisiert werden, zum anderen werden sie auch zur Energieverteilung, bspw. in einem Stirnraddifferentialgetriebe, ge- nutzt.Planetary gears are well known in the art. On the one hand, they can be used to realize a transmission and a torque transmission from a drive shaft to an output shaft; on the other hand, they are also used for power distribution, for example in a spur gear differential.
Als Planetenträger wird dabei das Bauelement bezeichnet, das die Wellen trägt, auf denen die Planetenräder gelagert sind und so um diese rotieren. Eine Planetenbewegung der Planetenräder bewirkt eine Rotation des Planetenträ- gers um seinen Mittelpunkt. In der Regel ist der Planetenträger mit einer Abtriebswelle verbunden und überträgt seine Drehbewegung direkt auf die Abtriebswelle.As a planet carrier while the component is referred to, which carries the waves on which the planetary gears are mounted and rotate about this. A planetary movement of the planet gears causes a rotation of the planet carrier around its center. In general, the planet carrier is connected to an output shaft and transmits its rotary motion directly to the output shaft.
Die Verbindung des Planetenträgers mit der zentral angeordneten Abtriebswel- Ie erfolgt bei Planetengetrieben des Standes der Technik mittels Verschwei- ßens. So beschreibt die Druckschrift DE 41 38 548 C1 einen Planetenträger, der zur drehfesten Verbindung mit einer als Hohlwelle ausgebildeten Getriebewelle angepasst ist. Die Getriebewelle weist dazu an ihrem einen Wellenende einen Flansch auf, mit welchem radial nach innen weisende Randabschnitte von Stegteilen des Planetenträgers durch Schweißen so verbunden sind, dass Planetenträger und Getriebewelle ein einziges starres Verbundteil bilden.The connection of the planet carrier with the centrally arranged output shaft is effected in planetary gears of the prior art by means of welding. Thus, the document DE 41 38 548 C1 describes a planet carrier, which is adapted to the rotationally fixed connection with a gear shaft designed as a hollow shaft. For this purpose, the gear shaft has at its one shaft end a flange, with which radially inwardly directed edge portions of web portions of the planet carrier are connected by welding so that planet carrier and gear shaft form a single rigid composite part.
Das Verschweißen der Getriebewelle mit dem Planetenträger stellt jedoch einen zusätzlichen Arbeitsschritt dar, der aufgrund des geringen vorhandenen Platzes an der Einbaustelle im Motorraum häufig schwierig oder vor dem Getriebeeinbau auszuführen ist. Darüber hinaus ist die Schweißverbindung nicht wieder lösbar, was den Ausbau des Getriebes unnötig kompliziert gestaltet. Letztlich kann es bei dem Verschweißen der Welle mit dem Planetenträger oder bei der Wartung der Schweißverbindung zu Fehlern kommen, die ein Ge- triebeversagen zur Folge haben können.However, the welding of the gear shaft with the planet carrier is an additional step, which is often difficult to perform or before the gear installation due to the small space available at the installation point in the engine compartment. In addition, the weld is not detachable again, which makes the expansion of the transmission unnecessarily complicated. Ultimately, when the shaft is welded to the planetary carrier or during the maintenance of the welded connection, errors can occur which can lead to a gearbox failure.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine alternative Verbindung des Planetenträgers mit einer Abtriebswelle bereitzustellen, die keine zusätzlichen Handgriffe bei der Montage erfordert und wieder lösbar ist.The invention has for its object to provide an alternative connection of the planet carrier with an output shaft that requires no additional handles during assembly and is releasable again.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird durch einen Planetenträger gemäß Anspruch 1 und ein Verfahren zur Herstellung eines Planetenträgers gemäß Anspruch 6 gelöst.This object is achieved by a planet carrier according to claim 1 and a method for producing a planet carrier according to claim 6.
Erfindungsgemäß wird ein Planetenträger für ein Planetengetriebe bereitgestellt, wobei der Planetenträger einen Planetenträgergrundkörper umfasst, der eine zentrale Ausnehmung zur Aufnahme einer Abtriebswelle aufweist, und dadurch gekennzeichnet ist, dass ein ringförmiges Zahnelement, das eine Innenverzahnung aufweist, drehfest in der zentralen Ausnehmung angeordnet ist. Erfindungsgemäß wird vorgesehen, den Planetenträger mit der Abtriebswelle über eine Steckverzahnung zu verbinden. Dabei wäre es zunächst möglich, die Innenverzahnung spannend direkt in dem Planetenträgergrundkörper auszubil- den.According to the invention, a planetary carrier is provided for a planetary gear, wherein the planet carrier comprises a planetary carrier main body having a central recess for receiving an output shaft, and characterized in that an annular toothed element having an internal toothing, rotatably disposed in the central recess. According to the invention it is provided to connect the planet carrier with the output shaft via a spline. In this case, it would be initially possible to form the internal toothing excitingly directly in the planetary carrier base body.
Bei den zu erwartenden Belastungen der Verzahnungsverbindung, wäre jedoch unbedingt eine Härtung der Verzahnung notwendig, um einem erhöhten Verschleiß an den Zähnen vorzubeugen.In the expected loads of the spline connection, however, a hardening of the teeth would necessarily be necessary to prevent increased wear on the teeth.
Dazu wäre allerdings der komplette Planetenträger wärme zu behandeln, was die Gefahr birgt, dass sich der Planetenträger verzieht.For this purpose, however, the entire planet carrier heat to treat, which carries the risk that the planet carrier warps.
Daher wird vorgesehen, die Innenverzahnung in einem ringförmigen Zahnele- ment vorzusehen, das wiederum mit dem Planetenträger verbunden wird.It is therefore provided to provide the internal toothing in an annular toothed element, which in turn is connected to the planetary carrier.
Auf diese Weise ist es möglich, das ringförmige Zahnelement wärmezubehan- deln und zu härten und es dann mit dem Planetenträger zu verbinden.In this way it is possible to heat treat the annular toothed element and harden and then connect it to the planet carrier.
Auf diese Weise wird vermieden, dass sich der Planetenträger aufgrund einer Wärmebehandlung verzieht und gleichzeitig wird der Verschleiß der Innenverzahnung durch die Härtung gesenkt.In this way it is avoided that the planet carrier warps due to a heat treatment and at the same time the wear of the internal toothing is lowered by the hardening.
Es kann vorgesehen sein, dass das Zahnelement in die zentrale Ausnehmung eingepresst ist. Auf diese Art wird auf einfache Weise eine kraftschlüssige Verbindung zwischen dem Planetenträger und dem Zahnelement bereitgestellt.It can be provided that the toothed element is pressed into the central recess. In this way, a frictional connection between the planet carrier and the tooth element is provided in a simple manner.
Eine Abtriebswelle, an deren einem Ende eine Außenverzahnung vorgesehen ist, kann dann einfach über eine Steckverbindung mit dem Planetenträger wie- der lösbar verbunden werden.An output shaft, at one end of which an external toothing is provided, can then be easily detachably connected to the planet carrier via a plug connection.
Das Zahnelement des Planetenträgers kann des weiteren dadurch gekennzeichnet sein, dass an dem Außenumfang des Zahnelements eine Profilierung vorgesehen ist, die mit einer an einem Umfang der zentralen Ausnehmung vorgesehenen komplementären Profilierung ineinander greift.The toothed element of the planetary carrier can furthermore be characterized in that a profiling on the outer circumference of the toothed element is provided, which engages with a provided on a circumference of the central recess complementary profiling.
Durch die entsprechenden Profilierungen des Außenumfangs des Zahnele- ments und des Umfangs der Ausnehmung des Planetenträgergrundkörpers kann eine formschlüssige Verbindung des Zahnelements mit dem Planetenträ- gergrundkörper bereitgestellt werden.By means of the corresponding profilings of the outer circumference of the toothed element and of the circumference of the recess of the planetary carrier main body, a positive connection of the toothed element to the planet carrier main body can be provided.
Selbstverständlich ist es möglich, auch im Falle einer Profilierung das Zahn- element in den Planetenträgergrundkörper einzupressen, so dass sowohl eine formschlüssige wie auch kraftschlüssige Verbindung bereitgestellt ist.Of course, it is also possible, in the case of a profiling, to press the toothed element into the planetary carrier base body, so that both a form-fitting and non-positive connection is provided.
Es kann vorgesehen sein, dass der Planetenträgergrundkörper zumindest teilweise mit dem Zahnelement verstemmt ist.It can be provided that the planet carrier base body is at least partially caulked with the toothed element.
Durch das Verstemmen des weichen bzw. ungehärteten Planetenträgergrundkörpers zu dem Zahnelement wird die Verbindung des Planetenträgergrundkörpers mit dem Zahnelement gestärkt und somit zuverlässig der axiale Sitz des Zahnelements sichergestellt.By caulking the soft or uncured Planetenträgergrundkörpers to the tooth element, the connection of the planet carrier main body is strengthened with the tooth element and thus reliably ensures the axial fit of the tooth element.
Es kann vorgesehen sein, dass das Zahnelement gehärtet ist. Wie bereits geschrieben wurde, kann mittels eines gehärteten Zahnelements einem hohen Verschleiß der Zähne der Innenverzahnung vorgebeugt werden.It can be provided that the toothed element is hardened. As has already been described, by means of a hardened tooth element a high wear of the teeth of the internal toothing can be prevented.
Ein erfindungsgemäßes Verfahren zur Herstellung eines Planetenträgers um- fasst die Schritte des Bereitstellens eines ringförmigen gehärteten Zahnelements mit einem profilierten Außenumfang und einer Innenverzahnung, des Bereitstellens eines Planetenträgergrundkörpers mit einer zentralen, komplementär zu dem Außenumfang des Zahnelements profilierten Ausnehmung und ist gekennzeichnet durch die Schritte des Einpressens des Zahnelements in den Planetenträgergrundkörper und des zumindest teilweisen Verstemmens des Planetenträgergrundkörpers zu dem Zahnelement. Durch das erfindungsgemäße Verfahren ist es auf besonders einfache Weise möglich einen Planetenträger herzustellen, der eine einfache, wieder lösbare Verbindung mittels einer Steckverzahnung mit einer Abtriebswelle ermöglicht, wobei der Verschleiß der Verzahnung aufgrund des gehärteten Zahnelements minimiert ist. Durch die Profilierung des Außenumfangs des Zahnelements sowie durch das Einpressen und das Verstemmen wird der feste Sitz des Zahnelements in dem Planetenträgergrundkörper sichergestellt.A method according to the invention for producing a planetary carrier comprises the steps of providing an annular hardened toothed element with a profiled outer circumference and an internal toothing, providing a planetary carrier main body with a central recess profiled in a complementary manner to the outer circumference of the toothed element and characterized by the steps of pressing in of the toothed element in the planet carrier base body and the at least partial caulking of the planet carrier main body to the toothed element. The inventive method, it is possible in a particularly simple manner to produce a planet carrier, which allows a simple, re-releasable connection by means of splines with an output shaft, wherein the wear of the toothing is minimized due to the hardened toothed element. By profiling the outer periphery of the toothed element as well as by pressing in and caulking, the tight fit of the toothed element in the planetary carrier base body is ensured.

Der erfindungsgemäße Planetenträger 100 besteht aus einem Planetenträger- grundkörper 10, der eine zentrale Ausnehmung 20 zur Aufnahme einer Antriebswelle aufweist. Der Planetenträger 100 umfasst des weiteren ein ringförmiges Zahnelement 30, das eine Innenverzahnung 32 aufweist und drehfest in der zentralen Ausnehmung 20 angeordnet ist.The planet carrier 100 according to the invention consists of a planet carrier basic body 10 having a central recess 20 for receiving a drive shaft. The planet carrier 100 further comprises an annular toothed element 30, which has an internal toothing 32 and is arranged rotationally fixed in the central recess 20.
Das ringförmige Zahnelement 30 weist an seinem Außenumfang eine Profilierung 34 auf und der Umfang der Ausnehmung 20 weist eine komplementäre Profilierung 22 zur Ausbildung einer formschlüssigen Verbindung auf.The annular toothed element 30 has on its outer circumference a profiling 34 and the circumference of the recess 20 has a complementary profiling 22 for forming a positive connection.
Auf diese Weise ist es möglich, durch Einpressen des Zahnelements 30 in den Planetengrundkörper 10 eine sowohl kraft- als auch formschlüssige Verbindung zwischen dem Zahnelement 30 und dem Planetengrundkörper 10 bereitzustellen.In this way, it is possible to provide by pressing the toothed element 30 into the planetary basic body 10 both a positive and positive connection between the toothed element 30 and the planetary basic body 10.
In der dargestellten Ausführungsform sind drei Planetenräder 12 vorgesehen, die auf dem Planetenträger 100 auf mit dem Planetenträgergrundkörper 10 verbundenen Wellenelementen 16 gelagert sind. Die Planetenräder 12 sind axial durch eine Scheibe 14 gesichert. Darüber hinaus weisen die Planetenräder 12 eine Schrägverzahnung zur Geräuschreduzierung auf.In the illustrated embodiment, three planetary gears 12 are provided, which are mounted on the planet carrier 100 connected to the planet carrier base body 10 shaft members 16.
