Retainer segment for swirler assembly

摘要

A retainer segment is provided for a swirler assembly having first and second members, such as a primary and secondary swirler or a swirler body and floating ferrule, disposed in sliding engagement with each other. The two members are maintained in sliding engagement by two of the retainer segments which are joined to the second member and engage the first member. Each retainer segment is an arcuate member defining inner and outer curved edges and first and second ends. Each end has a concave cutout formed therein to reduce weld joint and bending stresses that occur from the forced vibration of the retainer segments.
