Abstract

PURPOSE: To facilitate the pulling out of dovetail pins by covering dovetail pins which fix a turbine movable vane on a rotor disc by means of porous covering material which are impregnated with penetrant oil.
CONSTITUTION: On the dovetail 12 at the end part of a turbine movable vane 10, the grooves in fork shape are cut, and on the rotor disc 11 which fits with the dovetail 12, the grooves in fork shape are cut each of which corresponds to each groove on the dovetail 12. Dovetail pins 20 are inserted into common pin holes 14 to fix the turbine movable vane 10 and the disc 11. As the dovetail pin 20, is used the pin element 21 of which outer peripheral part is covered with porous covering mateiral 22 impregnated with penetant oil.
