Rotor system anti-rotation wear protector

摘要

A rotating control system includes a member having at least one clevis (46) defined by a pair of clevis arms (46a) disposed in a clevis plane, the at least one clevis (46) having an axis of symmetry disposed in the clevis plane midway between the pair of clevis arms, a shaft member (51) pivotally coupled between the pair of clevis arms, the shaft member (51) having a shaft axis, the shaft axis disposed axially along the shaft member (51), and an anti-rotation device (12, 65) for limiting a rotation of the shaft member (51) about the shaft axis, the anti-rotation device (12, 65) having a plurality of flanges (83) configured to couple to the clevis arms (46a) of the member, the flanges (83) extending from a surface (75) of a base member, the anti-rotation device (12, 65) having at least one restraining member (97) that protrudes toward the shaft member (51) for limiting the axial rotation of the shaft member (51).
