Description
<Desc/Clms Page number 1>
Die Erfindung betrifft eine Befestigung von Turbinenlauf-nnd-leitradschaufelo, welche gemeinsam, gegebenenfalls gruppenweise, durch ein Schaufelshloss in ontencbnittenen Nuten festgehalten werden.
Es ist üblich, die von einem gezogenen Profilstreifen abgeschnittenen und an ihrem Fusse entsprechend abgefrästen Schaufeln in eingefräste Nuten einer Radscheibe einzusetzen und an einer oder mehreren Stellen durch ein 8chlussstf1ck zusammenzuhalten.
Da nun die Wandstärke gering und bei sämtlichen Schaufeln für die gesamte Schaufel- länge die gleiche ist, kommt es vor, wenn das Verschlussstück nicht ganz genau eingepasst ist und die einzelnen Schaufeln daher nur lose anoinanderliegen, dass die Fusse der dem Verfschlussstück anliegenden Schaufeln Oberhaupt nicht in die unterschnittene Nute der Radscheibe hineinragen und die Schlussschaufeln während der Betriebes durch die Zentrifugal- kraft hinausgeschleudert werden.
Dieser Übelstand wird nun gemäss vorliegender Erfindung dadurch vermieden, dass man die Fusse der dem Schaufelschloss unmittelbar benachbarten Schaufeln an der dem

Die Füsse der beiden Schlussschaufeln c, f sind an ihrer dem Schaufelschloss abgekehrten Seite nut Ansätzen @ versehen. welche weit in die unterschnittene Nut hinonragen. so dass ein Herausfallen der Schlussschaufein unter allen Umständen verhütet wird.

The invention relates to a fastening of turbine running and stator blades, which are held together, optionally in groups, by a blade lock in cut-out grooves.
It is customary to insert the blades cut from a drawn profile strip and milled off at their feet into milled grooves in a wheel disk and to hold them together at one or more points by means of a connecting piece.
Since the wall thickness is now small and the same for the entire length of the blade for all blades, it happens when the closure piece is not fitted exactly and the individual blades are therefore only loosely attached to one another that the roots of the blades that are in contact with the closure piece are not at all protrude into the undercut groove of the wheel disc and the closing blades are thrown out by the centrifugal force during operation.
This inconvenience is avoided according to the present invention in that the feet of the blades immediately adjacent to the blade lock are attached to the

The subject matter of the invention is illustrated in an exemplary embodiment in the drawing.

The feet of the two closing blades c, f are provided with grooves @ on their side facing away from the blade lock. which protrude far into the undercut groove. so that falling out of the final window is prevented under all circumstances. Due to the approaches g are still on the Schaofelkranz for greater security
