Rotary machines and methods of assembling

摘要

A nozzle assembly is provided. The nozzle assembly includes at least one stationary nozzle. An outer ring having a predefined shape includes at least one groove defined therein and the groove is configured to receive at least a portion of the stationary nozzle therein. A coupling portion is formed integrally with the stationary nozzle or the outer ring such that the coupling portion extends outwardly therefrom. An attachment member is coupled to the coupling portion to facilitate substantially restricting movement of the stationary nozzle when the outer ring is substantially distorted.
