Abstract

PURPOSE: To decrease deformation and wear of a linkage of a turbine blade and to increase an oscillation damping effect by improving the shape of holes formed at bosses which foace each other on two sides of the blade face of a rotary blade and the shape of connector inlaid in these holes.
CONSTITUTION: A belly side boss 14 which runs along a belly side and a back side boss 15 which runs along a back side are formed at a blade face 4 of an adjoining rotary blade 2, and a connector 23 is inserted in to a hole 17 formed at each boss 14, 15. The hole 17 of the belly side boss 14 is made of an oblong 19 and a semi-circle 26 of a larger diameter and a jaw 21 which connects both parts 19 and 20, while the semi-circle 20 is situated at the exit side of a flow passage between blades. While the hole 17 of the back side boss 15 is similarly shaped, the semi-circle 20 is situated at the entry side of the flow passage between blades in this case. The connector 23 consists of a pillar-shaped part 35 having more or less the same section as that of the above-mentioned hole 17 and of a blade 28 with a semi-circule section; a tapered face 29 set at the blade 28 of each connector 23 links bosses 14, 15.
