Preventing rotation of a fixed ring of a swashplate

摘要

According to one embodiment, a rotor system (200) includes an anti-rotation sleeve (215) featuring an outer recess portion and a tilt sleeve (260) positioned about the anti-rotation sleeve (215) and having an opening therethrough. A first swashplate ring (116a, 240a) is positioned about the tilt sleeve (260) and features an inner recess portion. An anti-rotation mechanism is disposed through the opening and at least partially in the outer recess portion and the inner recess portion. The anti-rotation mechanism is operable to prevent the first swashplate ring from rotating about the anti-rotation sleeve. A second swashplate ring (116b, 240b) is positioned about the first swashplate ring (116a, 240b) and rotatable about the anti-rotation sleeve (215).
