 in gleichem Abstand voneinander festgehalten werden. Die festen Schaufeln A sind in ähnlicher Weise mit dem Gehäuse k verbunden. Gegenüber den Schaufeln g sind gezackte Abnutzstreifen   m   aus weichem Metall am Gehäuse leicht auswechselbar befestigt,   wählend   gegenüber den Schaufeln   h   ebensolche Abnutzatreifen p auf der Turbinentrommel oder-welle angeordnet sind. Beide Streifen können gleicher Gestalt sein. Der auf der Trommel sitzende Streifen p kann auch-breiter gehalten sein und kann dann durch Überstauchen der Zwischenstücke s befestigt werden. 



   Die Rippen liegen gewöhnlich in der Richtung des Umfanges senkrecht zur Wellenachse oder sie können in einer Spirale angeordnet sein, wobei die Spirale in der Richtung steigt, nach welcher der Abgang des Wassers erfolgt. Die Rippen können ununterbrochen oder auch mit mehr oder weniger Unterbrechungen angeordnet sein. 



   Wenn die Streifen abgenutzt sind, können dieselben leicht ausgewechselt werden. 



   Die Erfindung eignet sich sowohl für Turbinen als Turbokompressoren. 



    PATENT-ANSPRÜCHE:     l. Schaufeldichtung   für Turbinen und   Turbokompressoren, dadurch gekennzeichnet,   dass die äusseren Enden der Schaufeln gegenüber dem Gehäuse oder der Trommel durch auf einer oder beiden Seiten   smuindende Abschrägung   oder dgl. derart verschwächt sind, dass sie messerartige Kanten bilden, um die Gefahr des Abbrechens der Schaufeln zu vermeiden und Flächenreibung zu vermindern.

 be held at the same distance from each other. The fixed blades A are connected to the casing k in a similar manner. Opposite the blades g, serrated wear strips m made of soft metal are fastened to the housing in an easily replaceable manner, while opposite the blades h such wear strips p are arranged on the turbine drum or shaft. Both strips can be of the same shape. The strip p sitting on the drum can also be made wider and can then be fastened by upsetting the intermediate pieces s.



   The ribs are usually in the direction of the circumference perpendicular to the shaft axis or they can be arranged in a spiral, the spiral rising in the direction in which the water is discharged. The ribs can be arranged without interruption or with more or less interruptions.



   When the strips are worn, they can easily be replaced.



   The invention is suitable for both turbines and turbo compressors.



    PATENT CLAIMS: l. Blade seal for turbines and turbo compressors, characterized in that the outer ends of the blades opposite the housing or the drum are weakened by bevelling or the like on one or both sides in such a way that they form knife-like edges to avoid the risk of the blades breaking off avoid and reduce surface friction.

Claims (1)

2. Schaufeldichtung für Turbinen und Turbokompressoren mit im Anspruch 1 gekennzeichneten Schaufeln und diesen gegenüber angeordneten auswechselbaren Abnützstreifen, dadurch gekennzeichnet, dass der Streifen an seiner breiten Vorderfläche gegenüber den Schaufel- enden viele enge umlaufende Wellen bzw. Rippen besitzt, so dass der Streifen neben der Abnützfähigkeit und der Auswechselbarkeit eine stete Steifigkeit bewahrt. EMI2.1 2. Blade seal for turbines and turbo compressors with blades characterized in claim 1 and these oppositely arranged replaceable wear strips, characterized in that the strip has many narrow circumferential waves or ribs on its wide front surface opposite the blade ends, so that the strip next to the Ability to wear and interchangeability maintains constant rigidity.
