Description

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft die Lagerung einer Welle in einem Getriebe für ein Kraftfahrzeug, die über aus zwei einem Innenring und einem Außenring bestehende, von einander beabstandete Wälzlager in einem Getriebegehäuse aufgenommen ist, wobei jedes der Lager unterschiedlich ausgebildet ist und wobei das erste Lager als ein Kugellager ausgebildet ist und das zweite Lager eine Kombination eines Zylinderrollenlagers mit einem Kugellager ist.The invention relates to the mounting of a shaft in a transmission for a motor vehicle, which is received over two of an inner ring and an outer ring, spaced from each other rolling bearings in a transmission housing, wherein each of the bearings is formed differently and wherein the first bearing as a ball bearing is formed and the second bearing is a combination of a cylindrical roller bearing with a ball bearing.

Hintergrund der ErfindungBackground of the invention

Derartige Wellen, die im Getriebebau für Kraftfahrzeuge verwendet werden, werden über zwei von einander beabstandete Wälzlager gelagert, die gleichartig ausgebildet sind. So ist beispielsweise in dem Fachbuch „Wälzlagerungen-Berechnung und Gestaltung” von W. Hampp, Springer-Verlag Berlin/Heidelberg/New York in ein Ausgleichsgetriebe dargestellt. Die Kegelritzelwelle ist dabei über zwei voneinander beabstandete Kegelrollenlager gelagert, die in axialer Richtung vorgespannt sind. Die Vorspannung erfolgt derart, dass diese Kegelrollenlager mit Hilfe einer Schraubverbindung in axialer Richtung aufeinander zu bewegt werden.Such shafts, which are used in gearbox construction for motor vehicles, are mounted on two spaced-apart bearings, which are of similar design. For example, in the textbook "Rolling Bearings Calculation and Design" by W. Hampp, Springer-Verlag Berlin / Heidelberg / New York in a differential gear shown. The bevel pinion shaft is mounted on two spaced apart tapered roller bearings, which are biased in the axial direction. The bias is such that these tapered roller bearings are moved towards each other by means of a screw in the axial direction.

Aus der DE 21 32 891 A ist ein Antriebskegelradgetriebe bekannt geworden, dessen Kegelritzelwelle über zwei voneinander beabstandete Kugellager gehalten ist, die zueinander in O-Anordnung angestellt sind. Ein andere Art der Lagerung einer Kegelritzelwelle geht aus der DE 198 39 481 A1 hervor. In diesen Fall ist die Kegelritzelwelle über zwei einseitig belastbare zweireihige Tandem-Schrägkugellager gehalten, die wiederum zueinander in O-Anordnung angestellt sind. Schließlich geht aus US 2,147,144 eine weitere Art einer Kegelritzelwellenlagerung hervor. Diese erfolgt derart, dass die Kegelritzelwelle über zwei voneinander beabstandete doppelreihige Kugellager gehalten ist.From the DE 21 32 891 A a Antriebskegelradgetriebe has become known, the bevel pinion shaft is held by two spaced ball bearings, which are employed to each other in O arrangement. Another type of storage of a bevel pinion shaft goes out of the DE 198 39 481 A1 out. In this case, the bevel pinion shaft is held on two single-sided double-row tandem angular contact ball bearings, which are in turn made to each other in O arrangement. Finally, go out US 2,147,144 another type of bevel pinion shaft bearing forth. This takes place in such a way that the bevel pinion shaft is held over two spaced double-row ball bearings.

EP 1 443 228 A1 zeigt ein Achsgetriebe, in dem eine Ritzelwelle mit nur einem mehrreihigen kompakten Lager gelagert ist. Zwei Reihen des mehrreihigen Lagers weisen Kugeln mit und eine Reihe Kegelrollen auf. Das kompakte Lager ist ein in sich vorgespanntes Schräglager in O-Anordnung, in dem die beiden Kugelreihen auf der einen Seite gegen die Kegelrollen auf der anderen Seite angestellt sind. EP 1 443 228 A1 shows an axle, in which a pinion shaft is mounted with only a multi-row compact bearing. Two rows of multi-row bearing have balls with and a series of tapered rollers. The compact bearing is a self-prestressed angular contact bearing in O arrangement, in which the two rows of balls are set on one side against the tapered rollers on the other side.

JP 2000 002 239 A zeigt die Lagerung einer Getriebe- bzw. Ritzelwelle mit zwei axial voneinander beabstandet sind. Ritzelkopfseitig ist ein zweireihiges Kegelrollenlager angeordnet, dessen Außenring einen radial nach außen gerichteten Flansch aufweist, und das vom Ritzelkopf ferne Lager ist ein einreihiges Kugellager. JP 2000 002 239 A shows the storage of a gear or pinion shaft with two axially spaced apart. Pinion head side, a double row tapered roller bearing is arranged, whose outer ring has a radially outwardly directed flange, and the pinion head remote bearing is a single row ball bearing.

Der Nachteil derartiger Lagerungen ist zum Teil eine erhöhte Reibung, welche zu einer erhöhten Lagertemperatur führt. Ein weiterer Nachteil ist eine schwer einstellbare und nicht über die gesamte Laufzeit haltbare Vorspannungskraft.The disadvantage of such bearings is in part an increased friction, which leads to an elevated storage temperature. Another disadvantage is a difficult to adjust and not durable over the entire term biasing force.

In JP2003166627A ist deshalb eine Ritzelwellenlagerung beschrieben, die seitens des Ritzelkopfes mit einem zweireihigen Lager und an der vom Ritzel fernen Seite durch ein Schrägkugellager gebildet ist. Das zweireihige Lager ist mit einer Reihe Zylinderrollen und einer Reihe Kugeln bestückt. Die Lagerungen der Ritzelwelle sind spielfrei gehalten, in dem das Schrägkugellager auf der einen Seite und die in Schräglageranordnung ausgebildete Reihe Kugeln des zweireihigen Lagers gegeneinander angestellt sind.In JP2003166627A Therefore, a pinion shaft bearing is described, which is formed on the part of the pinion head with a double-row bearing and on the side remote from the pinion through an angular contact ball bearing. The double row bearing is equipped with a series of cylindrical rollers and a series of balls. The bearings of the pinion shaft are held without play, in which the angular contact ball bearings on the one hand and trained in angular contact arrangement row of balls of the double row bearing are employed against each other.

Das zweite Wälzlager 4 nimmt neben radialen Kräften auch axiale Kräfte auf, die auf die Welle 1 von rechts nach links einwirken und durch den Pfeil F1 dargestellt sind. Der Figur ist weiter entnehmbar, dass das als doppelreihiges Schrägkugellager ausgebildete erste Lager 3 und das Schrägkugellager 15 der zweiten Lagerkombination 4 zu einander in O-Anordnung angestellt sind, d. h., die zugehörigen Kugeldrucklinien verlaufen schräg in radialer Richtung von außen nach innen.The second rolling bearing 4 is as one of an angular contact ball bearing 15 and a cylindrical roller bearing 16 existing bearing combination of the prior art formed. The common inner ring 17 has a shoulder 18 and a board 19 on while the common outer ring 20 with the shoulder 21 is provided. Between both bearing rings 17 . 20 roll in a cage 22 guided bearing balls 23 and in a cage 24 guided cylindrical rollers 25 from. The second rolling bearing 4 In addition to radial forces also absorbs axial forces acting on the shaft 1 act from right to left and are represented by the arrow F1. The figure is further removed that designed as a double row angular contact ball bearing first bearing 3 and the angular contact ball bearing 15 the second camp combination 4 are set to each other in O arrangement, ie, the associated ball pressure lines are inclined in the radial direction from outside to inside.
