Description

Zahnradplanetengetriebe Planetengetriebe werden vielfach als übersetzungs- und Ausgleichgetriebe vorgeschlagen. Bei größeren zu übertragenden Kräften und hohen Geschwindigkeiten mußte man bisher jedoch von der Verwendung solcher Getriebe, insbesondere Stirnradplanetengetriebe, Abstand nehmen, weil in solchen Fällen die Planetenräder praktisch nie genau laufen, sondern ecken und zwängen. Es ist dies in der Eigenart der Herstellung der Einzelteile begründet, durch die es sich nicht erreichen läßt, daß die Drehachsen des Sonnenrads der Planetenräder und des Außenrades genau parallel verlaufen.Planetary gears Planetary gears are often used as translation and differential gear proposed. With larger forces to be transmitted and high Up to now, however, one had to avoid speeds from the use of such gear units, in particular Spur gears, refrain, because in such cases the planet gears practically never run exactly, but corners and squeeze. It is so in the nature the production of the individual parts by which it cannot be achieved, that the axes of rotation of the sun gear of the planetary gears and the outer gear are exactly parallel get lost.

Diesem Mangel hilft nun die Erfindung ab und erschließt damit ein neues Anwendungsgebiet für die Planetengetriebe. Die Planetenräder werden nämlich derart ausgebildet, daß sie zwischen den verschiedenen Ungenauigkeiten vermitteln und sich an diese anpassen können. Zu diesem Zweck wird das Planetenrad zwischen den mit ihm in Eingriff stehenden Zahnrädern frei einstellbar angeordnet und mit Pendellagern auf seiner Achse befestigt.The invention now remedies this deficiency and thus taps into it new field of application for the planetary gears. The planet gears are namely designed in such a way that they mediate between the various inaccuracies and can adapt to them. For this purpose, the planetary gear is between the gears in engagement with it are arranged freely adjustable and with Self-aligning bearings attached to its axis.

Planetengetriebe mit pendelnd auf der Achse gelagerten Planetenzahnrädern sind schon früher vorgeschlagen worden, die Planetenräder sind bei dieser Bauart aber nicht zwischen den Verzahnungen frei einstellbar, sondern ihre Lage wird durch seitlich ihrer Verzahnung angeordnete Laufringe bestimmt, welche bei Verlagerung der Achsen infolge von Herstellungsungenauigkeiten, Durchbiegungen u. dgl. durch Reibungsschluß das Drehmoment allein übertragen. Ferner treten pendelnde Planetenräder noch bei Reibradgetrieben mit verschieblicher Achse auf. Die Pendelung hat dabei den Zweck, die Ausnutzung der Axialdruckkomponente der verschiebbaren Welle zu ermöglichen, die Planetenräder laufen schräg zur Getriebeachse.Planetary gear with pendulum planetary gears on the axle have been suggested earlier, the planet gears are of this type but not freely adjustable between the teeth, but their position is through Races arranged to the side of their toothing determine which of them are displaced of the axes as a result of manufacturing inaccuracies, deflections and the like Frictional engagement transmit the torque alone. There are also oscillating planet gears still with friction gears with a movable axis. The pendulum has it the purpose of making it possible to utilize the axial pressure component of the displaceable shaft, the planet gears run at an angle to the gear axis.

In der Zeichnung ist ein neues Stirnradplanetengetriebe als Beispiel dargestellt.In the drawing is a new spur planetary gear as an example shown.

Die Kraft wird von einer der drei Wellen, etwa der Welle i, zugeleitet. Am Vorderende dieser Welle sitzt ein Ritzel 2, in welches die Planetenräder 3 eingreifen. Diese sind durch Verschraubungen 4. mit den Pendelrollenlagern 5 verbunden, die auf dem Bolzen G sitzen. Die Bolzen sind ihrerseits im Planetenradträger 7 gelagert, der in einen Zapfen 8 ausläuft.The force is supplied by one of the three waves, e.g. wave i. At the front end of this shaft there is a pinion 2, in which the planet gears 3 engage. These are connected by screw connections 4. with the spherical roller bearings 5, the sit on bolt G. The bolts are in turn mounted in the planet carrier 7, which runs out into a pin 8.

Das Außenrad io mit der Innenverzahnung i i umschließt das ganze Getriebe.The outer wheel io with the internal toothing i i encloses the entire gear unit.

Die neue Lagerung der Planetenräder kann auch bei Kegelradplanetengetrieben Verwendung finden.The new bearing of the planetary gears can also be used with bevel planetary gears Find use.
