Rotor for low-pressure thermal gas turbine, has rotor blade segments fastened with two clips that are engaged at opposite outer sides of blade segments at radial outer edge of rotor disk or rotor ring

摘要

The rotor (10) has a rotor blade rim (14) arranged at a rotor ring, where the rim comprises a rotor blade segment (16) and another rotor blade segment with a rotor blade (20) arranged at the segments. The segments are fastened with two clips (26, 28) that are engaged at opposite outer sides of the segments at a radial outer edge (30) of a rotor disk (12) or the ring. The clips are designed in a u-shaped manner, and short side pieces (32-38) of the clips engage into recesses (42, 44) e.g. grooves, in a floor area (40) of the segments and other recesses (46, 48) in the outer edge.
