Insbesondere bei der Lagerung von Planetenrädern in Planetengetrieben kommen häufig Zylinderrollenlager oder Pendelrollenlager zum Einsatz, deren Außenring in einer Bohrung im Planetenrad eingesetzt ist. Dabei ist vorgesehen, dass der Außenring des Lagers mit Presspassung in die Bohrung im Planetenrad platziert wird, um eine axiale Bewegung des Lageraußenrings relativ zum Planentenrad zu unterbinden. Allerdings kommt es dennoch häufig zu axialen Bewegungen des Außenrings relativ zum Rad. Dabei können hohe axiale Kräfte auftreten, die im Falle der Verwendung von Zylinderrollenlager zu einer sehr ungünstigen Belastung der Borde und im Falle der Verwendung von Pendelrollenlager zu einer ungleichmäßigen Lastverteilung führen.Especially in the storage of planetary gears in planetary gears come frequently Cylindrical roller bearings or spherical roller bearings are used, their outer ring is inserted in a hole in the planetary gear. It is intended that the outer ring of the bearing with a press fit placed in the hole in the planetary gear is an axial movement of the bearing outer ring relative to the planetary gear to prevent. However, it often comes to axial movements of the outer ring relative to the wheel high axial forces occur in the case of using cylindrical roller bearings to a very unfavorable Loading of the shelves and in case of using spherical roller bearings to an uneven load distribution to lead.
Ist eine axiale Verschiebung des Lageraußenrings relativ zum Planetenrad erfolgt, ist aufgrund der Presspassung zwischen den beiden Bauteilen ein Zurückgelangen in die ursprüngliche Relativposition sehr schwierig, so dass die Spannungen im Lager erhalten bleiben.is an axial displacement of the bearing outer ring relative to the planet gear is due to the interference fit between the two components back Get in the original one Relative position very difficult, so that the stresses in the bearing remain.
Die WO 94/24446 A1 offenbart ein Wälzlager, in dessen Außenring eine wendelförmig verlaufende Nut am Außenumfang eingearbeitet ist. Damit soll ein Pumpeffekt erzeugt werden, der zur Versorgung der Lageranordnung mit Schmieröl genutzt wird.The WO 94/24446 A1 discloses a roller bearing, in its outer ring a helical one extending groove on the outer circumference is incorporated. This is to create a pumping effect that is used to supply the bearing assembly with lubricating oil.

Die Adaption einer solchen Lösung bei der Lagerung insbesondere eines Planetenrades mittels einer Wälzlagerung ist nicht von Vorteil, da hier bei der Anordnung des Lager-Außenrings in der Bohrung des Planetenrades mittels Übergangspassung infolge der wendelförmigen Nut im Außenring ein unerwünschtes axiales Wandern des Lagerrings entsteht.The Adaptation of such a solution in the storage of a particular planetary gear by means of a roller bearing is not advantageous because here in the arrangement of the bearing outer ring in the bore of the planet gear by means of transitional fit due to helical Groove in the outer ring an undesirable axial migration of the bearing ring arises.
Bei zu großer Presspassung zwischen Lageraußenring und Bauteil ist auch häufig beobachtet worden, dass in unerwünschter Weise Passungsrost entsteht bzw. eine Fressneigung zwischen den beiden gepaarten Bauteilen vorliegt.at too big Press fit between bearing outer ring and component is also common been observed to be in undesirable Sage Frustration arises or a predatory tendency between the two paired components is present.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Lageranordnung der eingangs genannten Art zu schaffen, bei der eine spannungsfreie Lagerung insbesondere eines Planetenrads in einem Planetengetriebe ermöglicht wird, ohne dass es zu hohen Kräften zwischen Lagerung und Bauteil kommt. Damit sollen ungünstige Bordbelastungen, im Falle des Einsatzes von Zylinderrollenlagern, verhindert und eine ungünstige Lastverteilung, vor allem beim Einsatz von Pendelrollenlagern, ausgeschlossen werden. Es soll auch insbesondere sichergestellt sein, dass es zu keinen Problemen mit Passungsrost kommt.Of the Invention is therefore the object of a bearing assembly of the type mentioned above, in which a tension-free Storage in particular of a planetary gear in a planetary gear allows will, without it being too high forces between storage and component comes. This should be unfavorable on-board loads, in the Case of using cylindrical roller bearings, prevents and one unfavorable Load distribution, especially when using spherical roller bearings, excluded become. It should also be ensured in particular that it is too no problems with fretting comes.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass am Außenumfang des Außenrings und/oder in der Bohrung des Planetenrades mindestens eine wendelförmig verlaufende Nut eingearbeitet ist, wobei mindestens zwei axiale Abschnitte am Außenring und/oder am Planetenrad vorhanden sind, in denen die Nut gegensinnig verläuft.The solution this object by the invention is characterized in that on the outer circumference of the outer ring and / or in the bore of the planetary gear at least one helically extending Groove is incorporated, wherein at least two axial sections on outer ring and / or on the planet gear are present, in which the groove in opposite directions runs.
Dabei sind bevorzugt zwei axiale Abschnitte vorhanden. Diese können gleich groß ausgeführt sein.there Preferably, two axial sections are present. These can be the same be executed large.
Die wendelförmig verlaufende Nut ist bevorzugt in den Außenumfang des Außenrings eingearbeitet, wenngleich grundsätzlich auch ein Einarbeiten in die Bohrung des Planetenrades in Frage kommt.The helically extending groove is preferably in the outer periphery of the outer ring incorporated, albeit basically also an incorporation into the bore of the planetary gear in question.
Die wendelförmig verlaufende Nut kann eine Steigung aufweisen, die zwischen 5 % und 15 % des Außendurchmessers des Außenrings beträgt. Sie kann im Radialschnitt ausgerundet ausgebildet sein, insbesondere kreisförmig. Die Nut hat mit Vorteil eine maximale Tiefe, die zwischen 0,5 mm und 2,0 mm beträgt.The helically extending groove may have a slope between 5% and 15% of the outside diameter of the outer ring is. It can be rounded in radial section, in particular circular. The groove advantageously has a maximum depth of between 0.5 mm and 2.0 mm.
Der Außenring kann zumindest in einem axialen Endbereich mindestens eine stirnseitig angeordnete und sich radial erstreckende Nut aufweisen, wodurch der Fluss von Öl durch die Anordnung erleichtert wird.Of the outer ring can at least one end face in at least one axial end region arranged and radially extending groove, whereby the flow of oil is facilitated by the arrangement.
Zwischen dem Außenring und dem Planetenrad wird bevorzugt eine Übergangspassung vorgesehen.Between the outer ring and the tarpaulin tenrad is preferably provided a transition fit.
Das Wälzlager kann insbesondere ein Zylinderrollenlager sein, wobei dieses zweireihig ausgebildet sein kann. Weiterhin kann der Lagerinnenring Borde für die axiale Führung der Zylinderrollen aufweisen. Alternativ kann das Wälzlager auch als Pendelrollenlager ausgebildet sein.The roller bearing may in particular be a cylindrical roller bearing, this two-row can be trained. Furthermore, the bearing inner ring shelves for the axial guide having the cylindrical rollers. Alternatively, the rolling bearing also be designed as spherical roller bearings.
Mit dem Erfindungsvorschlag wird erreicht, dass eine spannungsfreie Lagerung des Bauteils mittels des Wälzlagers erfolgt. Insbesondere kann ein Planetenrad mittels eines Zylinderrollenlagers oder eines Pendelrollenlagers ohne ungünstige Bordbelastungen und ohne eine ungünstige Lastverteilung gelagert werden.With the invention proposal is achieved that a tension-free Storage of the component takes place by means of the rolling bearing. Especially can a planetary gear by means of a cylindrical roller bearing or a Spherical roller bearing without unfavorable On-board loads and stored without an unfavorable load distribution become.
Es ist eine Passung zwischen Lager und Bauteil möglich, die keine hohe Pressung benötigt. Damit sind auch die Bildung von Passungsrost und die Fressneigung stark reduziert.It is a fit between bearing and component possible, which does not require high pressure needed. In order to the formation of fretting and the tendency to eat are also strong reduced.
Die Aufnahmebohrung im Planetenrad kann in einfacherer Weise hergestellt werden, was deshalb von besonderem Vorteil ist, da häufig Planetenräder einen geringen Stahlreinheitsgrad aufweisen.The Mounting hole in the planet gear can be made in a simpler way be, which is why of particular advantage, as often planetary one have low steel purity.
Die Montage und Demontage des Planenterades ist wesentlich vereinfacht. Weiterhin ist auch eine Beschädigung des Lagers weniger leicht möglich.The Assembly and disassembly of the planetary wheel is considerably simplified. Furthermore, there is also damage of the camp less easily possible.
