Patent ID: 8226366

Claim:
An axial rotor section for a rotor of a turbine, comprising: an outer circumferential surface adjacent to two end first side surfaces in which rotor blade holding grooves for rotor blades of the turbine are distributed over the circumference and extend in an axial direction of the turbine; a further circumferential surface arranged radially further inwards relative to the outer circumferential surface and is adjacent to one of the two first side surfaces, wherein at least one sealing groove is provided with the further circumferential surface is open radially outwards, extends in the circumferential direction and has a plurality of sealing elements which are inserted therein and at least partially cover the end openings of the rotor blade holding grooves, wherein each sealing grove has associated side walls; a second side surface arranged adjacent to the further circumferential surface and with a hole for each sealing element being provided in the second side surface and passing through at least one of the side walls of the sealing groove, extending in the axial direction, with each sealing element being secured against movement in the circumferential direction by a bolt seated in the hole; a bolt securing device that secures each bolt against movement along the hole wherein the bolt securing device comprises a securing plate having at least one hole aligned with one of the holes in the side walls of the sealing groove such that the bolt inserted into the respectively aligned holes secures the securing plate against loosening; and a securing groove arranged in the further circumferential surface and is adjacent to the sealing groove and in which the securing plates are inserted.
