Patent ID: 6929215

Claim:
An aircraft rotor system comprising a tail boom made of a deformable material and formed to include an interior region containing a rotatable drive shaft, a gear box associated with the tail boom, the gear box including a housing formed to include a tail boom receiver and a retainer aperture opening into the tail boom receiver, a rotatable bevel gear mounted for rotation in an interior region of the housing and in spaced-apart relation to the tail boom and adapted to rotate tail rotor blades associated with the rotatable bevel gear, and a bushing arranged to support the drive shaft for rotation inside the tail boom receiver, a portion of the tail boom being located to lie between the bushing and the tail boom to confront the opening of the retainer aperture, and a housing retainer configured to move in the retainer aperture in a direction toward the bushing located in the tail boom receiver, the housing retainer including a force receiver adapted to mate with a force-producer tool and means for engaging an exterior surface of the tail boom and deforming the tail boom to move a deformed portion of the tail boom toward the bushing into a bushing channel formed in the bushing in response to movement of the housing retainer in the retainer aperture toward the bushing so that the housing is retained in a fixed position on the tail boom without hindering rotation of the drive shaft, and bevel gear within the housing.
