Description
Die Erfindung betrifft eine Verbindung zweier Teile einer Turbine miteinander mittels eines Gewindes. The invention relates to a connection between two parts of a turbine by means of a thread.
Solche Schraubverbindung läßt sich, vor allem wenn der Gewindedurchmesser groß ist, nur schwer spannen und schwer lösen, und zwar dies besonders, wenn das Gewinde in längerer Betriebszeit verkrustet ist.Such a screw connection is difficult, especially when the thread diameter is large tension and difficult to loosen, especially if the thread becomes encrusted after a long period of operation is.
Die Erfindung will das erleichtern. Sie will ermöglichen, die Verbindung zu spannen und zu lösen mittels Keilen, die in Umfangsrichtung zwischen Außengewindeteil und Innengewindeteil der Verbindung getrieben werden.The invention aims to make this easier. It wants to make it possible to tighten and loosen the connection by means of wedges, which are placed in the circumferential direction between the external thread part and the internal thread part of the connection to be driven.
Die Erfindung besteht darin, daß in der die Gewindegänge aufweisenden Fläche jedes der beiden Teile wenigstens zwei parallel zur Gewindeachse verlaufende Keilnuten vorgesehen sind und daß in der Kraftschlußstellung der Schraubverbindung jede Nut des Außengewindeteils mit je einer Nut des Innengewindeteils sich in Drehrichtung so teilweise deckt, daß in einer Drehrichtung das Außengewindeteil, in der anderen Drehrichtung das Innengewindeteil vor dem anderen Teil hervorsteht und daher ein in dieses Nutpaar eingetriebener Keil die Teile gegeneinander verdreht, und zwar ein in das eine Nutpaar eingetriebener Keil die Teile gegeneinanderspannt, aber ein ins andere Nutpaar getriebener Keil die Teile voneinander löst.The invention consists in that in the surface having the threads, each of the two Parts are provided at least two parallel to the thread axis extending keyways and that in the Non-positive position of the screw connection each groove of the external thread part with one groove of the internal thread part so partially coincides in the direction of rotation that in one direction of rotation the male thread part, in the other direction of rotation protrudes the internal thread part in front of the other part and therefore one in this Groove pair driven wedge rotates the parts against each other, namely one driven into the one groove pair Wedge clamps the parts against each other, but a wedge driven into the other pair of grooves clamps the parts separates from each other.
Spannen und Lösen der Verbindung kann noch durch reichliches Spiel des Gewindes, was an sich bekannt ist, erleichtert werden.Tensioning and loosening the connection can still be achieved by ample play of the thread, which is known per se is to be relieved.
Montage und Demontage lassen sich ferner dadurch erleichtern, daß die Nuten in Umfangsrichtung breiter als die Gewindesegmente sind, also das Gewinde ein an sich bekanntes Steckgewinde ist.Assembly and disassembly can also be facilitated in that the grooves are wider in the circumferential direction than the thread segments, so the thread is a plug-in thread known per se.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung in Fig. 1 im Schrägbild und in Fig. 2 und 3 in Mantelschnitten durch das Gewinde. Darin sind 9 ein Turbinengehäuseteil, 14 ein darin einzuschraubender Spannring, 17 und 17a Keilnuten; darin sind ferner G Gewindegänge des einen Teils, M Gewindegänge des anderen Teils, K ein Keil, S das Spiel zwischen den Gewindegängen. Fig. 2 zeigt das Spannen, Fig. 3 das Lösen der Verbindung.The drawing shows an embodiment of the invention in Fig. 1 in an oblique view and in Fig. 2 and 3 in shell sections through the thread. In it are 9 a turbine housing part, 14 a clamping ring to be screwed into it, 17 and 17a keyways; This also includes G threads of one part, M threads of the other part, K a wedge, S the play between the threads. Fig. 2 shows the tensioning, Fig. 3 the loosening of the connection.
