Aus der
Am inneren Umfang des Verstellrings befinden sich Aussparungen, in denen Verstellhebel mit einem kugelförmigen Ende schwenkbar gelagert sind. Die Verstellhebel sitzen mit ihrem anderen Ende drehfest auf einer Lagerachse der Leitschaufeln. Beim Verschwenken des Verstellrings werden somit alle Leitschaufeln in gleicher Weise verstellt.

Der Erfindung liegt die Aufgabe zugrunde, eine kurz bauende, leichtgängige Stelleinrichtung zu schaffen. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention has for its object to provide a short-built, smooth adjusting device. It is achieved according to the invention by the features of claim 1. Further advantageous embodiments will be apparent from the dependent claims.
Der Verstellring der Stelleinrichtung ist mittels Lagerkugeln am äußeren Umfang der Lagerplatte gelagert, wobei die Lagerkugeln in einem Kugelkäfig geführt sind. Die Lagerkugeln, die in Kugellaufbahnen der Lagerplatte und des Verstellrings laufen, werden durch den Kugelkäfig auf Distanz gehalten und verursachen minimale Reibungsverluste. Außerdem wird der Bauraum sowohl in radialer als auch in axialer Richtung optimal genutzt, zumal wenn gemäß der Erfindung die Verstellhebel in Nischen der Lagerplatte angeordnet sind, die stirnseitig und zum Umfang hin offen sind und eine Schwenkbewegung der Verstellhebel zulassen. Die Lagerkugeln sind dabei in den Bereichen zwischen den Nischen vorgesehen und werden durch den Kugelkäfig in Position gehalten, der mittels eines in den Käfig integrierten Anschlagelements an die Bewegung der Verstellhebel gekoppelt ist und Aussparungen für die Hebel besitzt. Dadurch kann der axiale Bauraum ohne Vergrößerung des radialen Bauraums verkleinert werden. Hinzu kommt, dass der axiale Abstand zwischen dem Mittelpunkt der Lagerkugel und dem Angriffspunkt der Hebel sehr gering ist, wodurch sich nur sehr kleine, vernachlässigbare Momente ergeben, die das Reibverhalten der Stelleinrichtung kaum beeinträchtigen.The adjusting ring of the adjusting device is mounted by means of bearing balls on the outer circumference of the bearing plate, wherein the bearing balls are guided in a ball cage. The bearing balls, which run in ball raceways of the bearing plate and the adjusting ring are held by the ball cage at a distance and cause minimal friction losses. In addition, the space is used optimally both in the radial and in the axial direction, especially if according to the invention, the adjusting levers are arranged in niches of the bearing plate, the front side and the periphery are open and allow pivotal movement of the lever. The bearing balls are provided in the areas between the niches and are held by the ball cage in position, which is coupled by means of a built-in cage stop member to the movement of the adjusting lever and has recesses for the lever. As a result, the axial space can be reduced without increasing the radial space. In addition, the axial distance between the center of the bearing ball and the point of application of the lever is very low, resulting in only very small, negligible moments, which hardly affect the friction behavior of the actuator.
Zur guten, reibungsarmen Führung der Lagerkugeln ist es zweckmäßig, dass der Kugelkäfig eingeprägte Kugelkalotten aufweist. Dadurch kann sich an den Kontaktflächen zwischen den Lagerkugeln und den Kugelkalotten bei der Bewegung ein Schmierfilm aufbauen.For good, low-friction guidance of the bearing balls, it is expedient that the ball cage has embossed spherical caps. As a result, a lubricant film can build up on the contact surfaces between the bearing balls and the spherical caps during the movement.
Nach einer Ausgestaltung der Erfindung sitzt ein Antriebshebel drehfest auf einer Antriebswelle, die ebenfalls in der Lagerplatte drehbar gelagert ist. Er greift mit seinem freien Ende in eine Aussparung des Verstellrings ein. Der Antriebshebel kann somit in der gleichen Ebene angeordnet werden wie die Verstellhebel, sodass er keinen zusätzlichen axialen oder radialen Bauraum beansprucht.According to one embodiment of the invention, a drive lever is non-rotatably mounted on a drive shaft, which is also rotatably mounted in the bearing plate. He engages with its free end in a recess of the adjusting ring. The drive lever can thus be arranged in the same plane as the adjusting lever, so that it does not require additional axial or radial space.

Eine Stelleinrichtung 10 umfasst im Wesentlichen einen Verstellring 11, mehrere Verstellhebel 14 und einen Antriebshebel 28. Der Verstellring 11 ist mittels mehrerer Lagerkugeln 20 am äußeren Umfang einer Lagerplatte 18 gelagert. Die Lagerkugeln 20 laufen einerseits in einer Kugellaufbahn 25 der Lagerplatte 18 und in einer Kugellaufbahn 26 des Verstellrings 11. Sie werden durch einen Kugelkäfig 21 geführt und auf Abstand gehalten. Dieser besitzt im Bereich der Lagerkugeln 20 einprägte Kugelkalotten 22.An adjusting
Der Verstellring 11 wird über den Antriebshebel 28 angetrieben, der mit einem Ende auf einer Antriebswelle 29 drehfest sitzt, die in der Lagerplatte 18 drehbar gelagert ist. Die Antriebswelle 29 wird von einem nicht dargestellten Aktuator betätigt. Das andere Ende des Antriebshebels 28 greift mit einem Kopf 15 in eine entsprechende Aussparung 12 des Verstellrings 11. Bei einer Schwenkbewegung des Antriebshebels 28 um die Antriebswelle 29 wird der Verstellring 11 um einen begrenzten Drehwinkelbereich verstellt.The adjusting
Die Verstellhebel 14 sind über den Umfang der Lagerplatte 18 verteilt und sitzen mit einem Mitnahmeende 16 drehfest, z.B. über ein polygonales Mitnahmeprofil, auf einer Achse 17, die drehbar in der Lagerplatte 18 gelagert ist. An dem anderen Ende der Achse 17 ist eine Leitschaufel befestigt, die jedoch nicht sichtbar ist. Wird die Achse 17 durch den Verstellhebel 14 geschwenkt, dreht sich im gleichen Sinne die zugehörige Leitschaufel.The adjusting
Die freien Ende der Verstellhebel 14 besitzen Köpfe 15, die in entsprechende Aussparungen 12 des Verstellrings 11 eingreifen und so bei einer Verstellung des Verstellrings 11 mitgenommen werden und die Verstellbewegung auf die Achsen 17 übertragen.The free end of the adjusting
Die Verstellhebel 14 und der Antriebshebel 28 sind in Nischen 19 der Lagerplatte 18 untergebracht. Diese sind zur Stirnseite und zum Umfang hin offen und lassen eine ausreichende Schwenkbewegung der Hebel 14, 28 zu. Die Nischen 19 reichen axial bis in den Bereich der Kugellaufbahn 25, sodass der axiale Abstand 27 zwischen dem Mittelpunkt der Lagerkugel 20 und dem resultierenden Angriffspunkt der Köpfe 15 der Verstellhebel 14 und des Antriebshebels 28 sehr klein ist, wodurch die durch den Abstand 27 bedingten Momente ebenfalls sehr klein sind. Bei der Verstellung des Verstellrings 11 bewegen sich die Lagerkugeln 20 in Bereichen 24 jeweils zwischen zwei benachbarten Nischen 19. Sie werden in dieser Lage durch den Kugelkäfig 21 gehalten, der mittels eines in den Kugelkäfig 21 integrierten Anschlagelements 23 an die Bewegung der Verstellhebel 14 gekoppelt ist. Eine Ankoppelung des Kugelkäfigs 21 auf der Hälfte der wirksamen Länge der Verstellhebel 14 führt dazu, dass dem Kugelkäfig 21 über das Anschlagelement 23 genau die Umfangsgeschwindigkeit, nämlich die halbe Umfangsgeschwindigkeit des Verstellrings 11, mitgeteilt wird, die der Kugelkäfig 21 auch allein durch die Abwälzbewegung des Verstellrings 11 über die Lagerkugeln 20 auf der Lagerplatte 18 hätte. Dadurch wird die Reibung zwischen den Lagerkugeln 20 und dem Kugelkäfig 21 mit seinen Kugelkalotten 22 minimiert und es wird gewährleistet, dass zwischen dem Verstellring 11, den Lagerkugeln 20 und der Lagerplatte 18 ausschließlich Rollreibung auftritt. Bei der Montage können die Lagerkugeln 20 von den Nischen 19 aus in ihre Position gebracht werden, bevor das Anschlagelement 23 und damit der Kugelkäfig 21 durch die Montage der Verstellhebel 14 auf den Achsen 17 in seiner Lage bestimmt wird. Damit der Kugelkäfig 21 den Bewegungsfreiraum der Verstellhebel 14 und des Antriebshebels 28 nicht beeinträchtigt, besitzt er im Bereich der Nischen 19 entsprechende Aussparungen 30 (Fig. 4). Um die bei der Verstellung zu bewegenden Massen gering zu halten, ist der äußere Umfang 13 des Verstellrings 11 zwischen den Aussparungen 12 zumindest teilweise im Durchmesser reduziert. Dies ist jedoch nicht zweckmäßig in dem Bereich des Antriebshebels 28 und der benachbarten Verstellhebel 14, in dem die Aussparungen 12 sehr eng beieinander liegen.The adjusting
