Description
Die vorliegende Erfindung betrifft eine variable Turbinen- und/oder Verdichtergeometrie mit einem Schaufellagerring und drehbar daran bzw. darin gelagerten Leitschaufeln gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem eine mit einer derartigen variablen Turbinen- und/oder Verdichtergeometrie ausgestattete Ladeeinrichtung sowie ein Verfahren zur Montage einer derartigen variablen Turbinen- und/oder Verdichtergeometrie.The present invention relates to a variable turbine and / or compressor geometry with a vane ring and rotatably mounted therein or therein vanes according to the preamble of
Aus der
Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für eine gattungsgemäße variable Turbinen- und/oder Verdichtergeometrie eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die sich insbesondere durch eine einfache Montage sowie einen geringen Arbeitswiderstand auszeichnet.The present invention therefore deals with the problem of providing for a generic variable turbine and / or compressor geometry an improved or at least one alternative embodiment, which is characterized in particular by a simple assembly and a low resistance to working.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine Führungsrolle zum Führen eines Verstellrings an einem Schaufellagerring drehbar am Schaufellagerring zu lagern und an zumindest einer Führungsrolle eine Verliersicherung vorzusehen, die die Führungsrolle drehbar am Schaufellagerring fixiert. Durch die drehbare Lagerung der Führungsrolle am Schaufellagerring kann ein Verstellwiderstand zum Verstellen der variablen Turbinen- und/oder Verdichtergeometrie deutlich reduziert werden, da ein Rollwiderstand üblicherweise deutlich geringer ist als ein vergleichbarer Gleitwiderstand bei drehfest angeordneten Führungsrollen. Durch die zumindest eine Verliersicherung kann zudem die jeweils zugehörige Führungsrolle verliersicher am Schaufellagerring angeordnet werden und zwar insbesondere vor oder während der Montage des Verstellrings, wodurch die Montage der variablen Turbinen- und/oder Verdichtergeometrie und die weiteren Montageschritte insgesamt vereinfacht werden kann. Generell muss dabei nicht an jeder Führungsrolle eine zugehörige Verliersicherung vorgesehen sein, sondern üblicherweise lediglich an zumindest einer oder zwei, wobei die anderen Führungsrollen nach erfolgter Montage des Verstellringes über diesen in Axialrichtung fixiert sind.The present invention is based on the general idea of supporting a guide roller for guiding an adjusting ring on a blade bearing ring rotatably on the blade bearing ring and providing on at least one guide roller a captive securing device which rotatably fixes the guide roller on the blade bearing ring. Due to the rotatable mounting of the guide roller on the blade bearing ring, an adjusting resistor for adjusting the variable turbine and / or compressor geometry can be significantly reduced, since a rolling resistance is usually significantly lower than a comparable sliding resistance at non-rotatably arranged guide rollers. Due to the at least one captive securing device, the respectively associated guide roller can moreover be arranged captively on the blade bearing ring, in particular before or during assembly of the adjusting ring, whereby the assembly of the variable turbine and / or compressor geometry and the further assembly steps can be simplified as a whole. In general, it must not be provided on each guide roller an associated captive, but usually only at least one or two, the other guide rollers are fixed after the assembly of the adjusting ring on this in the axial direction.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, weist der Verstellring an seinem Innenumfang Ausnehmungen auf, die derart zu den Führungsrollen angeordnet sind, dass der Verstellring in Axialrichtung auf den Schaufellagerring aufsetzbar und in der Art eines Bajonettverschlusses an diesem fixierbar ist. Dies ermöglicht es, die Führungsrollen samt der zugehörigen Verliersicherungen vor dem Verstellring am Schaufellagerring zu montieren, wobei der Verstellring anschließend mit seinen Ausnehmungen derart zu den Führungsrollen positioniert werden kann, dass er axial über diese geschoben und anschließend verdreht werden kann, die Führungsrollen mit nicht ausgenommenen Innenumfangsbereichen des Verstellrings zusammenwirken und dadurch der Verstellring sowohl in Axial- als auch in Radialrichtung geführt ist. Anschließend können noch die Leitschaufeln am Schaufellagerring montiert und mit ihren Verstellhebeln in Eingriff mit dem Verstellring gebracht werden. Generell kann durch die erfindungsgemäßen am Innenumfang des Verstellrings vorgesehenen Ausnehmungen die Montage des Verstellrings am Schaufellagerring in der Art eines Bajonettverschlusses ausgestaltet und dadurch die Montage deutlich vereinfacht werden.In an advantageous development of the solution according to the invention, the adjusting ring on its inner circumference recesses, which are arranged in such a way to the guide rollers, that the adjusting ring in the axial direction on the blade bearing ring can be placed and fixed in the manner of a bayonet lock on this. This makes it possible to mount the guide rollers together with the associated Verliersicherungen before the adjusting ring on the blade bearing ring, the adjusting ring can then be positioned with its recesses to the guide rollers so that it can be pushed over this axially and then rotated, the guide rollers with not recessed Inner circumference regions of the adjusting cooperate and thereby the adjusting ring is guided both in the axial and in the radial direction. Subsequently, the vanes can still be mounted on the blade bearing ring and brought with their adjusting levers into engagement with the adjusting ring. In general, the mounting of the adjusting ring on the blade bearing ring in the manner of a bayonet closure can be configured by the invention provided on the inner circumference of the adjusting ring recesses and thus the assembly can be significantly simplified.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
