   Fig. 2 stellt eine Ausführungsform dar, bei der die Ringe   9   nicht zwischen den Innenteilen und dem Turbinengehäuse, sondern zwischen dem letzteren und dem Ständer der seitlich zum Turbinengehäuse verlegten, miteinander verbundenen Turbogeneratoren k angeordnet sind. 



   Bei Turbinen, bei denen das Turbinengehäuse a mit den durch die Verbände l vereinigten Turbogeneratoren k verbunden ist, und wo ferner der Abdampf, beispielsweise bei Gegendruckturbinen, von höherer Temperatur als wie die Ständer der Turbogeneratoren bzw. der Verbände   I   ist, dehnt sich das   Turbinengehäuse   a mehr als wie die Verbände l aus, so dass dasselbe zweckmässig durch konische   Verhäng     J   mit den Ständern der Turbogeneratoren verbunden wird, die eine freie Ausdehnung gestatten. 



   Bei dieser Ausführungsform muss die Konizität der Ringe   9   eine derartige sein, dass die rechtwinkeligen Linien   l'sich   in demselben in der Mittellinie gelegenen Punkte   h   kreuzen. 



   Es ist klar, dass die Verbände g anstatt gelenkig fest und federnd mit den Teilen a und b verbunden sein können. 



   Die Ringe können auch in abweichender Weise gestaltet sein. Bedingung ist nur, dass ihre Festpunkte in den beiden Teilen auf verschiedenen Radien liegen. 



   PATENT-ANSPRÜCHE :
1. Vorrichtung an radialen Dampf-oder Gasturbinen zum Ausgleich der zufolge der Erwärmung entstehenden axialen Ausdehnung der mit dem Turbinengehäuse verbundenen inneren oder äusseren Teile, dadurch gekennzeichnet, dass diese Teile mittels eines konisch gestalteten Ringes mit dem Turbinengehäuse verbunden sind.

 EMI2.1
 



   2 shows an embodiment in which the rings 9 are not arranged between the inner parts and the turbine housing, but between the latter and the stator of the interconnected turbo-generators k which are laid laterally to the turbine housing.



   In the case of turbines in which the turbine housing a is connected to the turbo-generators k united by the associations l, and where furthermore the exhaust steam, for example in the case of back pressure turbines, is at a higher temperature than the stator of the turbo-generators or the associations I, the turbine housing expands a more than that of the associations l, so that it is expediently connected by conical curtains J to the stands of the turbo-generators, which allow free expansion.



   In this embodiment, the conicity of the rings 9 must be such that the right-angled lines l 'cross at the same point h located in the center line.



   It is clear that the associations g, instead of being articulated, can be firmly and resiliently connected to the parts a and b.



   The rings can also be designed in a different way. The only condition is that their fixed points in the two parts lie on different radii.



   PATENT CLAIMS:
1. Device on radial steam or gas turbines to compensate for the axial expansion of the inner or outer parts connected to the turbine housing, which occurs as a result of the heating, characterized in that these parts are connected to the turbine housing by means of a conically shaped ring.
