Axial rotor section for a rotor in a turbine, sealing element for a turbine rotor equipped with rotor blades and rotor for a turbine

摘要

The section (12) has an outer peripheral surface adjacent to side surfaces (14), where rotor blade retaining grooves (18) are provided in the peripheral surface. An inner peripheral surface has a sealing groove (24) for holding sealing elements (32) and including an interruption-less contact surface (46). A front side projection (28) is provided in an opening of the sealing elements, where the projection is circular in an endless manner. The opening partially covers the groove in a circumferential direction and in an axial direction under the formation of an undercut. An independent claim is also included for a sealing element for a rotor of a turbine.
