Abstract

Disclosed is an axial rotor section for a rotor of a turbine, on which a sealing element, which is provided on an end side surface, is secured by means of a bolt against movement in the circumferential direction, with the bolt being reliably secured against becoming loose by means of a securing plate. One particular advantage of the invention is the comparatively simple and low-cost design, comprising a securing plate, a bolt, holes and grooves. Furthermore, these components can be fitted and removed quickly, because of their simple geometry.
