Description

Formteile aus Kunstkohle, z.. B. Ringsegmente, hat man bisher dadurch zu vollständigen Ringen zusammengefügt, -daß man die Stoßstellen miteinander verklebt hat. Diese Verbindung ist jedoch nicht genügend temperatürbeständig,'weil sich alle organischen Klebstoffe bei etwa 2,50° zersetzen. -Aus dem gleichen Grunde (irrangelnde Temperaturfestigkeit) versagen auch Weichlötungen..Molded parts made of charcoal, for example ring segments, have so far been used as a result put together to form complete rings -that the joints are glued together Has. However, this connection is not sufficiently temperature-resistant, 'because all organic adhesives decompose at about 2.50 °. - For the same reason (inaccurate Temperature resistance), even soft soldering fails.

Erfindungsgemäß wird eine sehr gute und tempe.-raturIestähdige Verbindung der Formteile durch gezahnte Schrägflächen erreicht, deren Zähn ineinan.dergreifen. und die durch eine zusätzliche Querverbindung, z. B. eine Schraube oder einen Niet, gegeneinandergedrückt werden. Diese Querverbindung wird dabei nur auf Zug beansprucht, während die Verzahnung die Querkrä'fte aufnimmt.According to the invention, a very good and temperature-resistant compound is obtained of the molded parts achieved by toothed inclined surfaces, the teeth of which interlock. and by an additional cross connection, e.g. B. a screw or a rivet, are pressed against each other. This cross connection is only subjected to tension, while the gearing absorbs the transverse forces.

Fertigungstechnisch besonders vorteilhaft ist eine Ausbildung beider Stoßstellen nach dem gleichen Umriß, - so daß sieh die Verzahnungen mit dem gleichen Werkzeug und daher genau ineinanderpassend herstellen lassen.An embodiment of both is particularly advantageous in terms of production technology Joints according to the same outline - so that you can see the toothing with the same Tool and therefore can be made to fit exactly into one another.

Bin Ausführungsbeispiel zeigt das Bild.The picture shows an exemplary embodiment.

i ist ein Formteil, in diesem Fall' ein Ringsegment, in perspektivischer Darstellung mit gezahnten Schrägflächen. Zwei solche Stücke i und 2 werden-arneinandergelegt -und mit der Schraube 3 in ihrer gegenseitigen Lage gehalten.i is a molded part, in this case 'a ring segment, in perspective Representation with toothed bevels. Two such pieces i and 2 are placed one on top of the other -and held in their mutual position with the screw 3.

Es wäre an sich auch möglich, mit einer senkrecht zur Schraubenachse liegenden gezahnten Fläche zu arbeiten. Die Anwendung der schrägen Fläche hat aber den Vorteil, daß der auf Abbrechen beanspruchte gezahnte Lappen einen stärkeren gefährdeten Querschnitt erhält, also weniger leicht bricht. Den' Grad der' Scihräge wird man also von Fall zu Fall bestimmen können oder unter Umständen auch ganz darauf verzichten. Die Zähnflanken sind gegen' die Achsrichtung der Schraube derart .geneigt, daß die Verzähnurng sich nicht lösen kann, ohne daß gleichzeitig die Schraube gelockert wird.It would also be possible per se, with one perpendicular to the screw axis lying toothed surface to work. However, the use of the inclined surface has the advantage that the toothed flap stressed to break off has a stronger one endangered cross-section receives, so breaks less easily. The 'degree of' skew one can therefore determine from case to case or, under certain circumstances, entirely on it waive. The tooth flanks are inclined towards the axial direction of the screw in such a way that that the Zahnurng cannot loosen without loosening the screw at the same time will.
