Description

Die Erfindung bezieht sich auf eine Lagerung für die Wellenstümpfe bei Absperrklappen. Bei den bekannten Absperrklappen werden die Wellenstümpfe der Klappenscheibe auf beiden Seiten des Gehäuses zusammen mit ihren Lagern, z. B. Nadellagern, und ihren Abdichtungen, z. B. Nutringmanschetten, in einer Nabe des Gehäuses untergebracht. Es gehört auch schon zum Stand der Technik, jeden Wellenstumpf mit Lager und Abdichtung in einer besonderen Flanschnabe unterzubringen, die in die Nabe des Klappengehäuses genau passend eingesetzt ist.The invention relates to a storage for the stub shafts with butterfly valves. In the known butterfly valves, the stub shafts are the Valve disc on both sides of the housing together with their bearings, e.g. B. needle roller bearings, and their seals, e.g. B. U-ring seals, housed in a hub of the housing. It is also part of the state of the art, every shaft stub with bearings and seals to be accommodated in a special flange hub, which is in the hub of the valve body is used exactly.

Bei diesen bekannten Konstruktionen besteht jedoch der Nachteil, daß ein guter Abschluß der Klappenscheibe auf ihrem Sitz nicht gewährleistet ist, da diese von der genauen Einhaltung des Abstandes der Drehachse der Klappe vom Klappensitz abhängig ist. Die Einhaltung dieser Bedingung erfordert aber eine überaus genaue und lohnintensive Bearbeitung des Klappensitzes und der Nabenbohrung.In these known constructions, however, there is the disadvantage that a good closure of the valve disc on its seat is not guaranteed because this depends on the exact observance of the distance between the axis of rotation of the valve and the valve seat is dependent. However, compliance with this condition requires a very precise one and labor-intensive machining of the valve seat and the hub bore.

Die Erfindung hat sich die Aufgabe gestellt, eine Lagerung für die Wellenstümpfe zu schaffen, bei der Herstellungsungenauigkeiten ausgeglichen werden können und ein sicherer Abschluß der Klappenscheibe auf dem Klappensitz erzielt wird. Die Erfindung besteht darin, daß die Flanschnabe mit radialem Spiel in die Gehäusenabe eingesetzt und durch Paßstifte zentriert und mittels Schrauben am Gehäuseflansch befestigt wird. Auf diese Weise kann bei der Endmontage infolge des radialen Spiels der Flanschnabe in der Gehäusenabe die Klappenscheibe mit den Wellenstümpfen und den Flanschnaben bis zum dichten Abschluß der Scheibe an ihrem Gehäusesitz tierangeschoben werden, worauf dann die beiden Flansche durch Paßstifte zentriert und dann gemeinsam für die Halteschrauben gebohrt werden. Die Montage wird dadurch wesentlich vereinfacht.The invention has the task of providing a storage for To create shaft stubs, in which manufacturing inaccuracies are compensated can and achieved a secure closure of the valve disc on the valve seat will. The invention consists in that the flange hub with radial play in the Housing hub inserted and centered by dowel pins and on the housing flange by means of screws is attached. In this way, during final assembly as a result of the radial play the flange hub in the housing hub the valve disc with the stub shaft and the flange hubs animal pushed up to the tight seal of the disc on its housing seat whereupon the two flanges are centered by dowel pins and then together for the retaining screws to be drilled. The assembly is thereby considerably simplified.

In der Zeichnung ist eine Wellenstumpflagerung gemäß der Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing is a shaft stub bearing according to the invention shown in one embodiment.

Das Gehäuse der Absperrklappe ist mit 1 bezeichnet. Dieses ist auf jeder Seite mit einer Gehäusenabe 2 versehen, die durch Rippen 3 gegen das Gehäuse 1 abgestützt ist. Der Wellenstumpf 4 trägt an seinem inneren Ende die Klappenscheibe 5; sein äußeres Ende ragt durch die Nabe 2 hindurch nach außen. Dieses Ende des Wellenstumpfes 4 ist mittels des Lagers 6 und der Dichtung 7 in der Flanschnabe 8 gelagert. Der innere Teil der Flanschnabe 8 greift mit radialem Spiel in die Bohrung der Gehäusenabe 2 ein; seine Außenfläche kann leicht konisch gestaltet sein. Die Flanschnabe 8 wird durch Paßstifte 9 im Flansch der Gehäusenabe 2 zentriert und dann durch Flanschschrauben 10 daran befestigt.The housing of the butterfly valve is denoted by 1. This is on each side provided with a housing hub 2, which by ribs 3 against the housing 1 is supported. The stub shaft 4 carries the valve disc at its inner end 5; its outer end protrudes through the hub 2 to the outside. This end of the The stub shaft 4 is in the flange hub by means of the bearing 6 and the seal 7 8 stored. The inner part of the flange hub 8 engages in the bore with radial play the housing hub 2 a; its outer surface can be designed to be slightly conical. the Flange hub 8 is centered by dowel pins 9 in the flange of the housing hub 2 and then attached to it by flange screws 10.
