Description

Verwendung von Rollenlagern mit elastischen Wälzkörpern (Federrollen) für die Lagerung der Umlaufräder bei Planetenrädergetrieben Es ist bekannt, daß bei Planetenrädergetrieben ein guter Eingriff sämtlicher Getrieberäder von großer Bedeutung ist, wenn ein einwandfreier, geräuschfreier Lauf des Getriebes sowie ein guter Wirkungsgrad erreicht werden soll.Use of roller bearings with elastic rolling elements (spring rollers) for the storage of the planetary gears in planetary gears It is known that in the case of planetary gears, good meshing of all large gears It is important if the gearbox runs properly and quietly as well as a good efficiency is to be achieved.

Ferner ist es bekannt, die Eingriffsverhältnisse bei Planetenrädern dadurch zu verbessern, daß die Planetenräder in Lagern abgestützt werden, die in radialer Richtung von Federn gehalten sind. Derartige Anordnungen sind insofern unvollkommen, als eine Nachgiebigkeit der Planetenräder nur in einer Richtung, nicht dagegen allseitig vorhanden ist. Bei einer anderen bekanntgewordenen Anordnung wird eine allseitige Nachgiebigkeit der Planetenräder dadurch erreicht, daß zwischen die Planetenräder und die zur Lagerung dienenden Zapfen Federbuchsen eingeschaltet sind, welche eine geringfügige Nachgiebigkeit der Planetenräder in jeder Richtung ermöglichen.It is also known that the meshing conditions in planetary gears to improve in that the planet gears are supported in bearings that are in are held in the radial direction by springs. Such arrangements are insofar imperfect, as a flexibility of the planet gears only in one direction, not on the other hand is present on all sides. Another known arrangement is an all-round resilience of the planetary gears achieved in that between the planetary gears and the journals used for storage are switched on are showing a slight sag of the planet gears in any direction enable.

Gemäß der Erfindung wird gegenüber diesen bekannten Anordnungen eine Verbesserung dadurch erreicht, daß für die Lagerung der Planetenräder auf den zur Abstützung dienenden Zapfen Rollenlager mit elastischen Wälzkörpern, sog. Federrollenlager, verwendet werden. Ein Getriebe gemäß der Erfindung zeichnet sich dadurch aus, daß einerseits für die Planetenlagerung Wälzlager verwendet werden, was bekanntlich für den Wirkungsgrad von Vorteil ist, und daß andererseits besondere Teile zur Erzielung einer allseitigen Nachgiebigkeit der Planetenräder vermieden werden. Diese Anordnung ermöglicht eine derartige Einstellbarkeit der Planetenräder, daß eine gleichmäßige Zahndruckverteilung auf sämtliche Planetenräder vorhanden ist.According to the invention is compared to these known arrangements Improvement achieved in that for the storage of the planetary gears on the Supporting trunnions Roller bearings with elastic rolling elements, so-called spring roller bearings, be used. A transmission according to the invention is characterized in that on the one hand roller bearings are used for the planetary bearing, which is known for the efficiency is advantageous, and that on the other hand, special parts to achieve an all-round resilience of the planetary gears can be avoided. This arrangement allows such adjustability of the planetary gears that a uniform Tooth pressure distribution is present on all planetary gears.

Im folgenden soll die Erfindung an Hand eines Ausführungsbeispiels erläutert werden. In Fig. i bedeutet i das Getriebegehäuse, 2 die treibende und 3 die getriebene Welle. Das Ritzel 4. der treibenden Welle steht mit den Planetenrädern 5 in Eingriff, die sich an dem im Gehäuse befestigten Zahnkranz 6 abwälzen. Die Planetenräder 5 sind auf Zapfen 7 abgestützt, die starr mit dem mit der abgetriebenen Welle 3 verbundenen Käfig 8 verbunden sind. Die Lagerung der Planetenräder 6 an dem Zapfen 7 erfolgt mit Hilfe von Federrollenlagern 9, wie sie in Fig. 2 gezeigt sind. Die Federrollenlager gewährleisten bei dieser Anordnung eine solche Nachgiebigkeit, daß unter allen Umständen ein guter Eingriff der Getrieberäder gesichert ist. An sich sind nachgiebige Wälzlager (Federrollenlager) bereits bekannt.In the following, the invention will be explained using an exemplary embodiment. In Fig. I i means the gear housing, 2 the driving and 3 the driven shaft. The pinion 4 of the driving shaft meshes with the planetary gears 5, which roll on the ring gear 6 fastened in the housing. The planet gears 5 are supported on pins 7 which are rigidly connected to the cage 8 connected to the driven shaft 3. The planet gears 6 are mounted on the journal 7 with the aid of spring roller bearings 9, as shown in FIG. In this arrangement, the spring roller bearings ensure such flexibility that good engagement of the gear wheels is ensured under all circumstances. Resilient roller bearings (spring roller bearings) are already known per se.
