Abstract

Rotor einer Turbomaschine, mit einem Rotorgrundkörper und mehreren Laufschaufeln, wobei jede Laufschaufel ein Schaufelblatt (11) und ein Koppelelementsegment(10, 10', 10") aufweist, Erfindungsgemäß ist das Koppelelementsegment (10, 10', 10") einer jeden Laufschaufel an einer ersten Seite (16) und an einer gegenüberliegenden zweiten Seite (17) derart konturiert ist, dass an der ersten Seite und an der zweiten Seite eine sich im wesentlichen in Axialrichtung erstreckende radial äußere Kante (18, 19) und eine sich im wesentlichen in Axialrichtung erstreckende radial innere Kante (20, 21) des jeweiligen Koppelelementsegments jeweils zwei durch eine Trennlinie (26, 27) voneinander getrennte Flächen begrenzen, wobei an mindestens einer Umfangsposition des Rotors zwischen zwei unmittelbar benachbarten Laufschaufeln die an unmittelbar benachbarten Seiten (16, 17) der Koppelelementsegmente (10', 10") ausgebildeten Trennlinien (26, 27) in etwa annähernd parallel zu der über die Schaufelfüße definierten Montagerichtung der Laufschaufeln am Rotorgrundkörper verlaufen, wohingegen an jeder anderen Umfangsposition zwischen zwei unmittelbar benachbarten Laufschaufeln die an unmittelbar benachbarten Seiten der Koppelelementsegmente (10, 10', 10") ausgebildeten Trennlinien (26, 27) zur Montagerichtung schräggestellt sind. (Fig. 1)
