Abstract:
A support system for attaching the aft end of a gas turbine transition duct to a turbine inlet housing to provide three degrees of freedom of relative movement between the duct and the turbine inlet comprising:a) a base member contoured to an outer wall of the transition duct member and rigidly attachable thereto; b) said base member further including rigidly attached fingers; c) a support assembly including: a central bracket having a central spherical ball mount at one end connected within said base member fingers, providing three degrees of freedom of movement between the base member and the central bracket and a mounting surface at the other end for mating the transition duct to said turbine inlet; a pair of contoured washers sized to mate to said central spherical ball mount and constructed of such material as to absorb wear from said spherical ball mount due to vibrations; a pair of contoured ring mounts to accept said contoured washers and spherical ball mount sized to fit between said contoured washers and said fingers; an interconnecting fastener fitted through said fingers, contoured ring mounts, contoured washers, and central spherical ball mount for retaining said central spherical ball mount with three degrees of freedom; said interconnecting fastener configured such that a force maybe applied to said fingers and contoured ring mounts to resist said motion of said central spherical ball mount with three degrees of freedom.
