Description

Die Erfindung bezieht sich auf eine Einstellvorrichtung gemäß Oberbegriff des Anspruchs 1; eine derartige Einstellvorrichtung ist aus der EP-A1-0 169 450, insbes. FIG 1, bekannt.The invention relates to an adjusting device according to the preamble of claim 1; such an adjustment device is known from EP-A1-0 169 450, in particular FIG. 1.

Bei der bekannten, die Verstellung eines Drallreglers eines Ventilators betreffenden Einstellvorrichtung sind die zu ver­stellenden Leitschaufeln des Drallregers mit einem radial innen vorstehenden Lagerzapfen in Lageraufnahmen einer Nabe drehbar gelagert. Auf der Nabe ist konzentrisch zu dieser ein Verstellring zwischen zwei Gleitscheiben drehbar gelagert. Die zentrale Verstellung sämtlicher über den Umfang der Nabe verteilt angeordneten Leitschaufeln erfolgt durch Verdrehen des Verstellringes mittels eines Bowdenzuges, der in einem Halte­blech abgestützt und über ein Kugelgelenk am Verstellring angelenkt ist. Zur Übertragung der Verstellbewegung des Verstellringes auf die Leitschaufeln weisen diese an ihrem radial inneren Ende einen axial abgebogenen Mitnahmerahmen mit einem mittig radial abstehenden Stellstift auf, der zwischen zwei axial vorstehende, an dem Verstellring befestigte Führungsstifte greift.In the known adjustment device relating to the adjustment of a swirl controller of a fan, the guide vanes of the swirl controller to be adjusted are rotatably mounted in bearing receptacles of a hub with a radially projecting bearing journal. An adjusting ring is rotatably mounted on the hub between two sliding disks. The central adjustment of all guide vanes distributed over the circumference of the hub takes place by turning the adjustment ring by means of a Bowden cable which is supported in a holding plate and is articulated on the adjustment ring via a ball joint. To transmit the adjusting movement of the adjusting ring to the guide vanes, they have an axially bent driving frame at their radially inner end with a centrally radially protruding adjusting pin which engages between two axially projecting guide pins attached to the adjusting ring.

Gemäß Aufgabe vorliegender Erfindung soll auf einfache Weise von einer gut zugänglichen Stelle eine zentrale Verstellung der örtlich entfernten Verstellorgane und die Fixierung der jeweils erreichten Einstellage ermöglicht werden.According to the object of the present invention, a central adjustment of the locally removed adjustment members and the fixing of the respectively achieved adjustment position are to be made possible in a simple manner from an easily accessible location.

Die Lösung dieser Aufgabe gelingt bei einer Einstellvorrichtung der eingangs genannten Art erfindungsgemäß durch die Lehre des Anspruchs 1; vorteilhafte Ausgestaltungen der Erfindung sind jeweils Gegenstand der Unteransprüche.This object is achieved in an adjusting device of the type mentioned in the invention by the teaching of claim 1; advantageous embodiments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Einstellvorrichtung erlaubt durch ledig­lich einfaches Verdrehen der Einstellschraube und damit axiales Bewegen des Verstellschlittens eine Übertragung der Einstellbewegung auf die Verstellorgane, insbesondere den Verstellring und die Leitschaufeln eines Drallreglers, wobei nach Beendigung der Einstellbewegung die Einstellage ohne gesonderte weitere Hilfsmittel fixierbar ist.The adjustment device according to the invention allows the adjustment movement to be transferred to the adjustment elements, in particular the adjustment ring and the guide vanes of a swirl regulator, by simply simply turning the adjustment screw and thus axially moving the adjustment slide, the adjustment position being fixable without separate additional aids after the adjustment movement has ended.

Nach einer Ausgestaltung der Erfindung ist als vorteilhaftes Übertragungsmittel ein Seilzug, insbesondere ein Bowdenzug vorgesehen, dessen einstellseitiges Ende des Seilzuges bzw. des in einem umgebenden Schlauch verschiebbaren Drahtes des Bowden­zuges mit dem Einstellschlitten verbunden ist. Bei einem soge­nannten doppelseitigen Radialventilator werden in vorteilhafter Weise unter Verwendung nur eines einzigen Verstellschlittens beide zu je einem der beiden Drallregler führenden Bowdenzüge an dem Verstellschlitten befestigt, wobei zweckmäßigerweise die Einstellschraube zwischen den Enden der beiden Bowdenzüge, vorzugsweise mittig zwischen diesen Enden, am Einstellschlitten befestigt ist. Zur weiteren Vereinfachung der Einstellung ist nach einer Ausgestaltung der Erfindung vorgesehen, daß die jeweilige Einstellage des Einstellschlittens an einer, insbe­sondere mit einer Winkelmarkierung entsprechend dem Schließ­bzw. Öffnungswinkel der Leitschaufeln versehenen, Einstellskala am Abstützteil ablesbar ist.According to one embodiment of the invention, a cable, in particular a Bowden cable, is provided as an advantageous transmission means, the setting-side end of the cable or the wire of the Bowden cable which is displaceable in a surrounding hose is connected to the setting slide. In a so-called double-sided centrifugal fan, both Bowden cables leading to one of the two swirl regulators each are advantageously attached to the adjustment slide using only a single adjustment slide, the adjustment screw advantageously being attached to the adjustment slide between the ends of the two Bowden cables, preferably centrally between these ends . To further simplify the setting, it is provided according to one embodiment of the invention that the respective setting position of the setting slide on one, in particular with an angle mark corresponding to the closing or. Opening angle of the guide vanes provided, setting scale can be read on the support part.
