Description

Bei Umlaufrädergetrieben ist es infolge der unvermeidlichen Fehler in den Lagerungen und in der Verzahnung, besonders im innenverzahnten Radkranz, nicht möglich, bei starrer Lagerung aller umlaufenden Teile eine gleichmäßige Verteilung der Umfangskraft auf alle Umlaufräder zu erreichen.In epicyclic gears it is due to the inevitable errors in the bearings and in the toothing, especially in the internally toothed wheel rim, not possible with rigid mounting of all rotating parts an even distribution of the circumferential force to reach all planetary gears.

Es ist bereits vorgeschlagen worden, zur Behebung dieses Mangels die Umlaufräder federnd zwischen zwei gemeinsamen Trägern zu lagern. Dabei ist die Federung dadurch erreicht, daß über die starre Achse jedes Umlaufrades eine Buchse geschoben ist und in dem Raum zwischen dieser Achse und der Buchse Federkörper angeordnet sind. Die Federung ist hier also zwischen zwei Teilen (Achse und Buchse) angeordnet, die, zwecks Verhinderung der Drehung gegeneinander, miteinander durch einen Stift verbunden sein müssen. Dies hat zur Folge, daß die Federung sich nicht so auswirken kann, wie es für die angestrebte Wirkung erforderlich ist. Gemäß der Erfindung ist die Aufgabe unter Vermeidung dieses Mangels in der Weise gelöst worden, daß die Achsen der Umlaufräder, z. B. durch Verjüngung nach ihren Enden hin, federnd ausgebildet und nur in der Mitte zwischen beiden Trägern an je einer Hülse befestigt sind, die die Achse mit Spiel umschließt und auf der das zugehörige Umlaufrad, zweckmäßig mittels Wälzlager, abgestützt ist.It has already been proposed to remedy this deficiency using the planetary gears to be stored resiliently between two common carriers. The suspension is thereby achieved that a bushing is pushed over the rigid axis of each planetary gear and spring bodies are arranged in the space between this axis and the bushing. the Suspension is arranged here between two parts (axle and bushing), the purpose of Preventing rotation against each other, be connected to each other by a pin have to. As a result, the suspension cannot act as it does is necessary for the desired effect. According to the invention the task is been solved while avoiding this deficiency in such a way that the axes of the planetary gears, z. B. by tapering towards their ends, resilient and only in the middle between the two supports are each attached to a sleeve that encloses the axis with play and on the the associated planetary gear is expediently supported by means of roller bearings.

In der Zeichnung ist die Erfindung beispielsweise dargestellt. Die Zapfen 1 der Umlauf räder sind an den Enden in Tragkörpern z, 3 befestigt, 'die durch zwischen den Umlaufrädern liegende Bolzen unter Zwischenschaltung von Stützkörpern (nicht dargestellt) miteinander verbunden sind. Der Tragkörper 2 sitzt an der im Gehäuse 9 gelagerten Welle 8, während der Tragkörper 3 direkt im Gehäuse gelagert ist. In der Mitte ist jeder Zapfen an einem Hohlkörper 4 befestigt, der im übrigen den Zapfen lose umschließt und auf dem das als Hohlzylinder ausgebildete Umlaufrad 5 mittels Rollen 6, 7 gelagert ist. Der Zapfen ist nach den Enden hin verjüngt und 'dadurch federnd ausgebildet. Durch entsprechende Wahl des Querschnitts kann die Federung sowohl der Stärke als auch der Richtung nach beeinflußt werden. Wenn der Zapfen überall Kreisquerschnitt hat (Schnitt A-B), so ist der Bolzen allseitig federnd. Vorzugsweise wird der Querschnitt des Zapfens nach den Enden zu in Form eines stehenden Rechtecks ausgeführt (Schnitt C-D), so daß die Feder als Blattfeder wirkt, die in der Umlaufrichtung der Räder federt.In the drawing, the invention is shown by way of example. The pins 1 of the rotating wheels are attached at the ends in supporting bodies z, 3, 'which are connected to one another by bolts located between the rotating gears with the interposition of support bodies (not shown). The support body 2 sits on the shaft 8 mounted in the housing 9, while the support body 3 is mounted directly in the housing. In the middle, each pin is fastened to a hollow body 4 which, moreover, loosely encloses the pin and on which the rotating wheel 5, designed as a hollow cylinder, is mounted by means of rollers 6, 7. The pin is tapered towards the ends and is thus designed to be resilient. By appropriate choice of the cross section, the suspension can be influenced both in terms of strength and direction. If the pin has a circular cross-section (section AB), the bolt is resilient on all sides. The cross section of the pin is preferably designed in the form of a standing rectangle towards the ends (section CD), so that the spring acts as a leaf spring which springs in the direction of rotation of the wheels.
