Abstract
A turbine nozzle assembly includes an outer casing having first and second spaced apart support flanges for supporting a nozzle segment including a plurality of nozzle vanes extending between inner and outer bands. The outer band includes first and second spaced apart retention hooks, with the first hook being configured to axially engage the first support flange. And, the second support flange is sized for axially receiving the second hook without tilting of the nozzle segment. An annular retainer radially engages the second support flange and axially abuts the second hook for axially retaining the second hook. And, a clip axially engages the second hook and support flange around the retainer for radially supporting the nozzle segment to the outer casing.
Claims10
A retainer for axially retaining a gas turbine engine nozzle segment in an outer casing having a radially inwardly facing slot, and comprising a ring being L-shaped in section and including integral radial and axial stems, and with said radial stem being sized to engage said slot.
A retainer for axially retaining a gas turbine engine nozzle segment in an outer casing which includes axially spaced apart first and second support flanges for engaging corresponding first and second retention hooks of said nozzle segment, said retainer comprising:
- a ring being L-shaped in section and including integral radial and axial stems;
- and
- said retainer stem extends radially outwardly from said axial stem for engaging a complementary radial slot of said second support flange.
A retainer for retaining a turbine nozzle segment in an outer casing comprising a ring including:
- first means for radially engaging a radial slot in said casing and axially abutting said nozzle segment;
- and
- second means integrally joined with said first means for radially abutting said casing for reacting moment carried through said retainer from said nozzle segment.
A turbine nozzle retainer for permitting axial assembly of a turbine nozzle segment in an outer casing without tilting, comprising:
- a ring having a radial stem for radially engaging said casing and for axially abutting said nozzle segment, and an integral axial stem for radially abutting said casing for reacting moment carried through said retainer from said nozzle segment.
