Abstract

PURPOSE: In turbine blade integrated with the disc, to increase the vibration attenuating effect with simple structure.
CONSTITUTION: In order to attenuate the vibration of turbine blade 1 integrated with the disc 2, a hole 3 is made in the balde 1 from the tip toward the center while another hole 4 extending axially is made in the outer circumference of disc 2 where both holes cross perpendicularly to provide T-shape in the disc. Split pin 5 having hooks 7, 7 formed such that the max. Width is approximately same with the diameter of hole 3 when inserting the foot 9, 9 into said hole 3 is inserted while closing the foot 9, 9 to project the hook 7 into the hole 4. Then a set pin 6 having a groove 8 at one side is inserted from one end of hole 4, and said hook 7 is fitted in said groove 8 to hold the split pin 5.
