Abstract
Description
Die Erfindung betrifft ein Planetengetriebe nach dem Patentanspruch 1 und nach dem Gegenstand der älteren Patentanmeldung der Anmelderin mit dem Aktenzeichen 101 44 805.8.The invention relates to a planetary gear claim 1 and according to the subject of the earlier patent application the applicant with the file number 101 44 805.8.
Bei dem Planetengetriebe nach der älteren Anmeldung ist der Planetenträger über zwei Lager, welche beiderseits eines Hohlrades angeordnet und als Schräglager ausgebildet sind, gelagert. Derartige Kegelrollenlager sind kostenaufwendig und beanspruchen eine relativ große axiale Bautiefe und darüber hinaus auch radialen Bauraum wegen der Innen- und Außenringe der Kegelrollenlager.With the planetary gear after the older registration is the planet carrier over two Bearing, which is arranged on both sides of a ring gear and designed as an angular bearing are stored. Such tapered roller bearings are expensive and claim a relatively large axial depth and beyond also radial installation space due to the inner and outer rings of the tapered roller bearings.
Es ist Aufgabe der vorliegenden Erfindung, eine verbesserte Lagerung des Planetenträgers des eingangs genannten Planetengetriebes zu schaffen, welches weniger Bauraum beansprucht und eine Kostenreduzierung für das gesamte Getriebe ermöglicht.It is an object of the present invention improved storage of the planet carrier of the aforementioned To create planetary gear, which takes up less space and a cost reduction for the entire transmission enables.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Patentanspruches 1. Als Vorteil wird dabei erreicht, dass der Planetenträger nur noch über ein Lager, welches radiale und axiale Kräfte aufnimmt, gegenüber dem Gehäuse gelagert ist. Dieses Lager ist als Kreuzrollenlager ausgebildet und läuft auf einem geteilten Lagerinnenring, während die äußeren Laufbahnen des Kreuzrollenlagers in das Gehäuse eingearbeitet sind. Der Planetenträger kann daher aus einem Material gefertigt werden, welches nicht für die Rollenkörper des Lagers gehärtet werden muss.The solution to this problem results itself from the features of claim 1. As an advantage thereby achieved that the planet carrier only has one Bearing, which absorbs radial and axial forces, against the casing is stored. This bearing is designed as a crossed roller bearing and runs on a split bearing inner ring, while the outer raceways of the crossed roller bearing in the housing are incorporated. The planet carrier can therefore be made of one material are manufactured, which is not for the reel body of the Bearing hardened must become.

In vorteilhafter Ausgestaltung der Erfindung ist das Kreuzrollenlager in einer Radialebene angeordnet, die – in axialer Richtung – zwischen den beiden Planeten liegt. Damit ergibt sich eine günstige Lagerbelastung und eine axial verkürzte Bauweise für das gesamte Planetengetriebe.In an advantageous embodiment of the Invention, the crossed roller bearing is arranged in a radial plane, in the axial direction - between the two planets. This results in a favorable bearing load and an axially shortened one Construction for the entire planetary gear.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist der geteilte Innenring durch Spannmittel axial auf dem Planetenträger fixiert. Damit kann das Lager einfach montiert und eingestellt werden.In a further advantageous embodiment the invention is the divided inner ring by clamping means axially on the planet carrier fixed. This means that the bearing can be easily assembled and adjusted.
In vorteilhafter Weiterbildung der Erfindung sind die Spannmittel als schräg angeordnete Schraubelemente bzw. Gewindestifte ausgebildet, wobei vorteilhafter Weise auch eine senkrecht zur Stützrichtung angeordnete Fase am Innenring des Lagers vorgesehen ist. Dadurch ergibt sich eine optimale Stützwirkung auf das Kreuzrollenlager. Die einzelnen Stütz- oder Spannelemente, die am Planetenträger befestigt sind, greifen dabei zwischen den Planetenrädern hindurch. Auch dadurch ergibt sich eine kompakte Bauweise.In an advantageous development of the Invention are the clamping means as obliquely arranged screw elements or set screws, advantageously also one perpendicular to the direction of support arranged chamfer is provided on the inner ring of the bearing. Thereby there is an optimal support effect on the crossed roller bearing. The individual support or tensioning elements that attached to the planet carrier are reaching between the planet gears. That too the result is a compact design.
