Abstract

PURPOSE: To improve rigidity of turbine rotor blades and prevent decrease of its performance by combining a cover with a combination member which is provided on the inner periphery of the cover in every space between adjucent turbine rotor blades.
CONSTITUTION: A combination member 9 is formed of a plate portion 10 having end surfaces 10aW10d, and a similar configuration to the outer periphery of fluid passage 12, and a protrusion 11 projected radially outwardly at the central portion of the plate portion 10. A notch 13, step 17 and a through hole 15 are provided on cover of turbine rotor blade 1, and a plate shaped protrusion 14 is disposed on the end surface 10d of a combination member 9. The combination member 9 is arranged within a fluid passage 12 formed between blades 1, and the protrusion 11 is inserted in the through hole 15 of the cover 2 and also the plate shaped protrusion 14 is closely attached to the notch 13. Furthermore, the end portion 10c and step 17 are placed closely, and after the top of the protrusion 11 is caulked into a counter bore 16, each combined surface is formed by grinding along the grinding lines 18, 19.
