Description
Die Erfindung betrifft ein Zweigang-Planetengetriebe nach dem Oberbegriff des Anspruchs 1. Derartige Schaltgetriebe werden beispielsweise in Werkzeugmaschinen eingesetzt, in denen mittels einer Schalteinrichtung, deren Stellglied ein Elektromotor mit Getriebe sein kann, eine Umschaltung aus einem direkten Gang (i = 1) in eine Übersetzung mit i ≠ 1, meistens ins Langsame, durchgeführt wird. Die Umschaltung erfolgt dabei über eine axial verschiebbare Schaltmuffe, die auch als gefangene Schiebemuffe bezeichnet wird und über eine Innenverzahnung das Hohlrad mit dem Gehäuse des Planetengetriebes oder mit der Nabe verbindet.The invention relates to a two-speed planetary gear according to the preamble of claim 1. Such transmissions are used for example in machine tools, in which by means of a switching device whose actuator may be an electric motor with gear, switching from a direct gear (i = 1) in one Translation with i ≠ 1, mostly slow. The switching takes place via an axially displaceable sliding sleeve, which is also referred to as trapped sliding sleeve and connects via an internal toothing of the ring gear with the housing of the planetary gear or with the hub.
In modernen Werkzeugmaschinen, beispielsweise Drehmaschinen oder Fräsmaschinen, sind die Anforderungen hinsichtlich Drehzahl, Schwingungen und Genauigkeit sehr groß. Aus diesem Grund ist es unerlässlich, in den Planetengetrieben Unwuchten auf ein Mindestmaß zu beschränken, um die Bearbeitung der Werkstückoberflächen so exakt wie möglich durchführen zu können.In modern machine tools, such as lathes or milling machines, the requirements in terms of speed, vibration and accuracy are very large. For this reason, it is essential to minimize imbalances in the planetary gearboxes in order to be able to carry out the machining of the workpiece surfaces as precisely as possible.
Gegenstand der
Der Erfindung liegt die Aufgabe zugrunde, ein Planetengetriebe der eingangs erläuterten Gattung so auszubilden, dass bei der Herstellung der Aussenverzahnung der Nabe der Fräsvorgang in axialer Richtung nicht behindert wird, ohne dass dabei die Zentriereigenschaften zwischen Nabe und Schaltmuffe beeinträchtigt werden.The invention has the object of providing a planetary gear of the type described above in such a way that in the manufacture of the external teeth of the hub milling in the axial direction is not hindered, without affecting the centering between the hub and the shift sleeve.
Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, das die Mittel zur Zentrierung der verschiebbaren Schaltmuffe auf der Nabe aus einem Spielpassungs-Zentrierspalt zwischen den Zahnköpfen der Nabe und den Zahnfüßen der Schaltmuffe bestehen, die weniger als 0,1 mm betragen, vorzugsweise zwischen 0,05 und 0,07 mm.To achieve this object is provided according to the invention, which consist of the means for centering the sliding shift sleeve on the hub of a Spielpassungs Zentrierspalt between the tooth tips of the hub and the tooth roots of the shift sleeve, which are less than 0.1 mm, preferably between 0 , 05 and 0.07 mm.
Diese Lösung hat gegenüber dem Stand der Technik den Vorteil, dass ein Zentrierbund nicht mehr erforderlich ist, weil die Zentrierung nun unmittelbar über die Verzahnung zwischen dem Kopfkreis der Nabe und dem Fußkreis der Schaltmuffe erfolgt. Die Verzahnung kann so exakt hergestellt werden, dass auch bei hohen Drehzahlen keine nennenswerten Schwingungen auftreten, die eine genaue Oberflächenbearbeitung beeinträchtigen würden.This solution has the advantage over the prior art that a centering collar is no longer necessary, because the centering is now done directly on the teeth between the tip circle of the hub and the Fußkreis the shift sleeve. The teeth can be made so accurately that even at high speeds no appreciable vibrations occur that would affect a precise surface finish.
In vorteilhafter Weiterbildung der Erfindung haben die Kopfkreisverzahnung der Nabe und die Fußkreisverzahnung der Schaltmuffe in Schieberichtung der Schaltmuffe eine Einführungsschräge, die zur achsparallelen Horizontalrichtung einen Winkel von 10° haben kann.In an advantageous embodiment of the invention, the head circle toothing of the hub and the Fußkreisverzahnung the shift sleeve in the sliding direction of the shift sleeve an insertion bevel, which may have an angle of 10 ° to the axis-parallel horizontal direction.
Die Erfindung ist nachstehend an einem Ausführungsbeispiels erläutert, das in der Zeichnung dargestellt ist. Es zeigen:The invention is explained below with reference to an embodiment which is shown in the drawing. Show it:
