Assembly for securing a function position of a side plate on a rotor disk arranged relative to a rotor blade assembled on the rotor disk

摘要

The invention relates to an arrangement for securing a functional position of a arranged on an outer circumference of a rotor of a rotor of a gas turbine cover plate (2) of the rotor relative to a arranged on the outer circumference of the rotor disc rotor blade (1) of the rotor, wherein between the cover plate located in its functional position and one of the cover plate facing side of a blade root (4) of the blade (1) a channel portion of an annular cooling channel is formed, comprising a arranged on the cover plate side facing the blade root web, which is arranged on the blade root (4) that the The web (5) extends radially with respect to the rotor disk when the rotor disk is arranged on the rotor disk, a guide portion formed by a thickening formed on the cover plate and a guide opening formed by a through hole arranged on the cover plate, wherein the guide Gsabschnitt the guide opening at least partially surrounds a continuous longitudinal bore having a safety pin whose outer diameter corresponds to the inner diameter of the guide hole and which has two diametrically arranged at one end, open towards this end and equally spaced recesses, which are parallel from this end of the locking bolt extend to the longitudinal axis of the securing bolt over part of the length of the securing bolt, wherein the width b A of the recesses is greater than or equal to the width b S of the web (5), and a securing device for securing a functional position of the securing bolt on the cover plate and the Blade (1).
