Abstract

PURPOSE: In a turbine blade integrated with the disc, to increase the vibration attenuating effect with simple structure.
CONSTITUTION: The turbine rotor is equipped with a turbine disc 1 and integrated turbine blade 2. In order to attenuate the vibration of said blade 2, a hole 3 having tapered section 3c and extending from the tip toward the base is made in the power blade 2, then an attenuation absorving rod 4 is inserted into said hole 3 and supported by pressure insertion of fork piece 5 having inner tapered hole 5b and a plurality of notches 5d and ring groove 5c at the perimeter. When pressure inserting the fork piece 5 into small hole 3a, the tapered tip of attenuation absorving rod 4 enlarge the lower section of said piece 5 conically and pressure contacts with the tapered hole 3c to support the attenuation absorving rod 4.
