Abstract:
PROBLEM TO BE SOLVED: To provide a shaft assembly that can reduce manufacturing time and waste material relative to forging and machining a typical nut lock.SOLUTION: The shaft assembly 10 includes a shaft 12, a nut 40, a nut lock ring 42 and a tubular nut support ring 44. The shaft 12 includes a nut base 46 mounted on the shaft 12, and a plurality of protrusions 48 that extend radially outward from the base 46. Adjacent protrusions 48 are circumferentially separated apart from each other by a gap 58. The ring 42 includes a tubular ring base 60 connected axially between a plurality of first lock tabs 62 and a plurality of second lock tabs 64. The base 60 is disposed on the base 46. Each tab 62 extends radially inward through one of the respective notches 32. Each tab 64 extends axially through one of the respective gaps 58. The ring 44 is disposed on the base 60.
Abstract:
A rotary seal for sealing a bladed rotor of a gas turbine engine to a stator thereof comprises a sealing element and a sealing element support comprising a radially outer edge portion on which the sealing element is fixed, a radially inner mounting portion adapted to be attached to a supported rotor hub, and a flexible, medial web portion extending between the radially outer edge portion and the radially inner mounting portion.
Abstract:
A fan section for a gas turbine engine includes a fan hub having blade slots for receiving a root of a fan blade. A lock ring is configured to move rotatably from an unlocked position to a locked position for securing the blade root in the blade slot. A nose cone is secured to the lock ring, and thereby secured to the fan section.
