Abstract
Description
Die vorliegende Erfindung betrifft eine Vorspannmutter für eine axiale Vorspannung zweier spielfrei gegeneinander angestellter Wälzlager, mittels denen eine Ritzelwelle gelagert ist. Die Vorspannmutter ist über ein Innengewinde mit der Ritzelwelle verschraubt, so dass Innenringe zusammen mit den Wälzlagern gegenüber einem Träger und der Ritzelwelle vorgespannt sind.The present invention relates to a preload nut for an axial preload of two play against each other employed bearings, by means of which a pinion shaft is mounted. The preload nut is screwed through an internal thread with the pinion shaft, so that inner rings are biased together with the bearings relative to a carrier and the pinion shaft.
Hintergrund der ErfindungBackground of the invention
Im Stand der Technik ist es allseits bekannt und gebräuchlich mehrreihige Wälzlager mit einer Vorspannmutter auf einer Welle zu befestigen, so dass beispielsweise ein Vorspannwert eines mehrreihigen vorgespannten Wälzlagers dauerhaft gewährleistet ist oder zu befestigende Wälzlager zuverlässig und dauerhaft positioniert sind, insbesondere für den Fall bedeutender Axialkräfte im Betrieb.In the prior art, it is well known and customary to fasten multi-row roller bearings with a preload nut on a shaft, so that, for example, a preload value of a multi-row prestressed rolling bearing is permanently ensured or mounted bearings are reliably and permanently positioned, especially in the case of significant axial forces in Business.
So offenbaren die deutschen Offenlegungsschriften
Die aus dem Stand der Technik bekannten Vorspannmuttern weisen durch ihre Gewindegänge keine abdichtende Funktion auf. Somit kann dann beispielsweise Öl von einem mit der Ritzelwelle mechanisch gekoppelten (Differenzial-)Getriebe in weitere nicht mit diesem Öl verträgliche Lagerkomponenten gelangen. Die Folge können dann Beschädigungen an diesen Lagerkomponenten sein. Problematisch ist dabei, dass bei einem Lager mit einer Vorspannmutter, der axiale Bauraum begrenzt ist, so dass eine hinter einer Vorspannmutter angeordnete axiale Dichtung nicht denkbar ist.The known from the prior art preload nuts have by their threads on no sealing function. Thus, for example, oil from a mechanically coupled to the pinion shaft (differential) gear can get into further not compatible with this oil bearing components. The result may then be damage to these bearing components. The problem is that in a bearing with a preload nut, the axial space is limited, so that an arranged behind a preload nut axial seal is not conceivable.
Die Aufgabe der Erfindung ist daher, eine Vorspannmutter zu schaffen, die gleichzeitig eine Dichtfunktion erfüllt.The object of the invention is therefore to provide a preload nut which simultaneously fulfills a sealing function.
Die Aufgabe wird durch eine Vorspannmutter gelöst, die die Merkmale des Anspruchs 1 umfasst.The object is achieved by a biasing nut comprising the features of claim 1.
Die erfindungsgemäße Vorspannmutter dient für eine axiale Vorspannung zweier spielfrei gegeneinander angestellter Wälzlager, mittels denen eine Ritzelwelle gelagert ist. Die beiden Wälzlager sitzen mit jeweils einem Innenring auf der Ritzelwelle. Die Vorspannmutter ist dabei über ein Innengewinde mit der Ritzelwelle verschraubt, so dass die Innenringe zusammen mit den Wälzlagern gegenüber einem Träger und der Ritzelwelle vorgespannt sind.The preload nut according to the invention serves for an axial prestressing of two antifriction roller bearings which are free of play against each other by means of which a pinion shaft is mounted. The two rolling bearings each sit with an inner ring on the pinion shaft. The preload nut is screwed via an internal thread with the pinion shaft, so that the inner rings are biased together with the bearings relative to a carrier and the pinion shaft.
Erfindungsgemäß ist eine Nut in der Vorspannmutter ausgebildet, in der ein O-Ring angeordnet ist. Ferner bildet erfindungsgemäß eine Außenfläche der Vorspannmutter eine Laufbahn für zwei Radialwellendichtringe.According to the invention, a groove is formed in the preload nut, in which an O-ring is arranged. Further, according to the invention, an outer surface of the preload nut forms a raceway for two radial shaft seals.
Ein Vorteil der erfindungsgemäßen Vorspannmutter besteht darin, dass durch die Anordnung des O-Rings in der Nut die Vorspannmutter gegen die Ritzelwelle statisch abgedichtet ist, so dass dadurch kein Öl, beispielsweise von einem mit der Ritzelwelle mechanisch gekoppelten (Differenzial-)Getriebe, in weitere nicht dafür vorgesehene Lagerkomponenten gelangt.An advantage of the biasing nut according to the invention is that the biasing nut is statically sealed against the pinion shaft by the arrangement of the O-ring in the groove, so that thereby no oil, for example, from a mechanically coupled to the pinion shaft (differential) gear, in more not provided for bearing components passes.
Ein weiterer Vorteil der erfindungsgemäßen Vorspannmutter ist, dass durch die Anordnung der zwei Radialwellendichtringe auf der Außenfläche der Vorspannmutter eine Abdichtung von zwei Getrieben gewährleistet ist. Dies ist dann der Fall, wenn die Vorspannmutter beispielsweise in einer Antriebsvorrichtung mit mindestens einer elektrischen Maschine angeordnet ist. Die elektrische Maschine ist dann mit einem Getriebe verbunden. Das Getriebe ist wiederum mit der durch eine Rotorwelle der elektrischen Maschine hindurchgeführten Ritzelwelle mit dem (Differenzial-)Getriebe mechanisch gekoppelt. Aufgrund unterschiedlicher Anforderungen der beiden Getriebe, werden auch zwei nach verschiedenen Kriterien ausgewählte Öle zur Schmierung der Getriebe genutzt, wobei die Radialwellendichtringe eine Abdichtung der beiden Getrieberäume übernehmen.Another advantage of the biasing nut according to the invention is that a seal of two gears is ensured by the arrangement of the two radial shaft seals on the outer surface of the preload nut. This is the case when the preload nut is arranged for example in a drive device with at least one electric machine. The electric machine is then connected to a transmission. The transmission is in turn mechanically coupled to the pinion shaft guided through a rotor shaft of the electric machine with the (differential) gear. Due to different requirements of the two gearboxes, two oils selected according to different criteria are also used to lubricate the gearboxes, with the radial shaft sealing rings sealing off the two gearboxes.
In einer ersten Ausführungsform ist ein Luftraum zwischen den beiden Radialwellendichtringen ausgebildet. Dieser hat den Vorteil, dass ein Vermischen des Öls vom Getriebe der elektrischen Maschine mit dem Öl vom (Differenzial-)Getriebe verhindert ist.In a first embodiment, an air space is formed between the two radial shaft sealing rings. This has the advantage that a mixing of the oil from the transmission of the electric machine with the oil from the (differential) gearbox is prevented.
In einer weiteren Ausführungsform ist an einem Bund der Vorspannmutter eine Mehrzahl von Aussparungen ausgebildet. Diese Aussparungen dienen zur Aufnahme eines Schlüssels, welcher zum Anziehen der Vorspannmutter, d. h. zum Befestigen der Vorspannmutter mit der Ritzelwelle, verwendet wird.In a further embodiment, a plurality of recesses is formed on a collar of the preload nut. These recesses serve to receive a key which is used to tighten the preload nut, d. H. for attaching the preload nut with the pinion shaft is used.
In einer weiteren Ausführungsform stützt sich eine Mehrzahl von Wälzkörpern der beiden Wälzlager am Träger ab, so dass deren äußere Wälzkörperlaufbahnen direkt am Träger ausgebildet sind. Dadurch, dass die äußeren Wälzkörperbahnen direkt am Träger ausgebildet sind, ist der Träger für die Mehrzahl der Wälzkörper der beiden Wälzlager ein gemeinsamer als Außenring ausgeführter Lagerring.In a further embodiment, a plurality of rolling elements of the two rolling bearings are supported on the carrier, so that their outer rolling body raceways are formed directly on the carrier. Characterized in that the outer Wälzkörperbahnen are formed directly on the carrier, the carrier for the plurality of rolling elements of the two rolling bearings is a common executed as an outer ring bearing ring.
In einer weiteren Ausführungsform ist ein Freistich am Innengewinde und/oder an der Außenfläche der Vorspannmutter ausgebildet. Ganz allgemein dienen Freistiche an Absätzen von Drehteilen, die geschliffen werden sollen, dazu, dass das ein Schleifwerkzeug bis in eine Ecke des Absatzes schleifen kann und keine Rundung im Werkzeug hinterlässt, die einen festen und genauen Sitz bei der Montage der Bauteile verhindern würde. Freistiche verhindern außerdem die sonst an scharfen Übergängen auftretende Kerbwirkung.In another embodiment, an undercut on the internal thread and / or on the outer surface of the preload nut is formed. Generally, undercuts to heels of turned parts that are to be ground serve to allow a grinding tool to grind into a corner of the heel and leave no rounding in the tool that would prevent a firm and accurate fit during assembly of the components. Undercuts also prevent the otherwise occurring at sharp transitions notch effect.
Bei der vorliegenden Erfindung bedeutet dies, dass der Freistich am Innengewinde der Vorspannmutter, einen festen und genauen Sitz der Vorspannmutter auf der Ritzelwelle und der Freistich an der Außenfläche einen ebenso festen und genauen Sitz von einem der beiden Radialwelldichtringen auf der Vorspannmutter zulässt.In the present invention, this means that the undercut on the female thread of the preload nut, a tight and accurate fit of the preload nut on the pinion shaft, and the undercut on the outer surface allow for a tight and accurate fit of one of the two radial corrugated seal rings on the preload nut.
Insbesondere sind die in den Ausführungsformen beschriebenen zwei Wälzlager Kegelrollenlager, die vorzugsweise in einer „O”-Anordnung axial vorgespannt sind. Denkbar ist aber auch, dass Zylinderrollenlager für beide Wälzlager zum Einsatz kommen.In particular, the two roller bearings described in the embodiments are tapered roller bearings, which are preferably axially biased in an "O" configuration. It is also conceivable that cylindrical roller bearings are used for both rolling bearings.
