TURBINE NOZZLE SUPPORTING DEVICE

摘要

PROBLEM TO BE SOLVED: To inhibit the vibration of a turbine nozzle in operating an engine and to prevent the generation of fretting between end faces of segments in advance. SOLUTION: A front flange 14 of an outer band 12 forming the turbine nozzle 11 is engaged with a hook part 16a of an inner peripheral face of an outer turbine case 16. A plate spring 20 curved to allow the load of the spring to act in the radial direction is mounted on a rear end part of a back plate 19 of a chip shroud 18 positioned on a front end of the turbine nozzle 11. The plate spring 20 is fitted in a space between the hook part 16a of the turbine case 16 and an outer band front end part 12a of the turbine nozzle 11 to support the turbine nozzle 11.
