摘要： PROBLEM TO BE SOLVED: To prevent a loss due to high temperature oxidation by suppressing the temperature of the divided ring, and to reduce the strains of the divided ring due to thermal deformation.
SOLUTION: Adjacent divided elements 39 are doubly joined by a sealing plate 53 and joining surfaces 54, 55. On the divided elements 39, cooling passages 59, 60 penetrating side edges 50, 51 facing from an outer peripheral surface 33 to the adjacent divided element 39 and blowing off air toward the side edges 50, 51 of the adjacent divided elements 39 are formed. Furthermore, on the divided elements 39, a first cooling passage penetrating an end surface in an upstream side from the outer peripheral surface 33, and a second cooling passage penetrating an end surface in a downstream side from the outer peripheral surface 33 are formed. Chamfering portions 56, 57 are respectively provided between an inner peripheral surface 55 and the side edges 50, 51. A protrusion (an undulation) 45 and a reinforcing rib are provided on the outer peripheral surface 33.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of a crack by suppressing a thermal stress.
SOLUTION: Ribs 15 are provided on surfaces of inner walls of passages 12b, 12c at positions after a cooling medium makes the first turn. A relative cooling difference between the passages 12a, 12b and 12c is reduced. A cooling fluid after a blade part 5 is cooled, is made to flow to a shank side. The fluid uniformly cools the blade part 5 and reduces in a temperature difference between the blade part 5 and the shank 3 via a platform 3. Thus, the occurrence of the crack is prevented by suppressing the thermal stress.

摘要： A gas turbine shroud segment (1) has an outer surface (1b) with radial (10b) and axial (10a) reinforcing ribs (10), forming a waffle grid where the axial ribs (10a) are higher than the radial ribs (10b) to reduce heat deformation of the shroud segment (1) which can influence tip clearance.

摘要： In the gas turbine split ring, on an outer peripheral surface 1b between two cabin attachment flanges, a circumferential rib which extends in the circumferential direction and an axial rib which extends in the axial direction and has a height taller than that of the circumferential rib are, respectively, formed in plural lines, so that it is possible to suppress heat deformation in the axial direction which largely contributes to reduction of the tip clearance compared to head deformation in the circumferential direction more efficiently.
