Nozzle and shroud mounting structure

摘要

The present nozzle and shroud assembly (34) mounting structure (38) configuration increases component life and reduces maintenance by reducing internal stress between the mounting structure (38) having a preestablished rate of thermal expansion and the nozzle and shroud assembly having a preestablished rate of thermal expansion being less than that of the mounting structure (38). The mounting structure (38) includes an outer sealing portion (40) forming a cradling member (102) in which an annular ring member (46) is slidably positioned. The mounting structure (38) further includes an inner mounting portion (42) to which a hooked end (74) of the nozzle and shroud assembly (34) is attached. As the inner mounting portion (42) expands and contracts, the nozzle and shroud assembly (34) slidably moves within the outer sealing portion (40).
