Preventing rotation of a fixed ring of a swashplate

摘要

According to one embodiment, a rotor system, comprise a mating element, a sleeve, a first swashplate ring, a locking element, and a second swashplate ring. The mating element having a first plurality of grooves a first plurality of ridges. The sleeve is positioned inside the mating element such that the sleeve prevents rotation of the mating element about the sleeve while allowing the mating element to translate along the sleeve. The sleeve has a second plurality of grooves mating with the first plurality of ridges and a second plurality of ridges mating with the first plurality of grooves. The first swashplate ring is positioned around the mating element, and the locking element prevents. the first swashplate ring from rotating about the sleeve. The second swashplate ring is rotatable about the sleeve.
