Abstract:
A turbine comprising:a rotor and a non-rotatable component about said rotor; a brush seal carried by the non-rotatable component; an arcuate sealing platform interposed between said brush seal and said rotor and having an arcuate seal surface; a locking device carried by said rotor; said locking device and said sealing platform having interengagable elements responsive to circumferential movement of said locking device and said platform relative to one another for locking said platform against radial outward movement relative to said rotor; and said brush seal being engagable with said arcuate seal surface to seal between said rotor and said non-rotatable component; said locking device and said platform including a plurality of teeth separated by a plurality of slots, the teeth of one of said locking device and said plaform being receivable through the slots of another of said locking device and said platform, said teeth being engageable with one another in response to movement of said platform relative to said locking device in a circumferential direction to preclude radial outward movement of said platform relative to said rotor; a stop carried by a tooth of one of said locking device and said platform engagable against a tooth of another of said locking device and said platform to preclude relative rotation of said rotor and said platform in one direction.
