Abstract: A self-retaining anti-rotation clip for a spherical-bearing rod end has two opposing spacer plates, each spacer plate having a curved edge portion for surrounding at least a portion of a ball of the rod end. A connector plate connects the spacer plates, such that the spacer plates are spaced from each other and generally parallel to each other. Retaining means are carried on the clip and adapted for retaining each spacer plate in a position generally adjacent one side of a body of the rod end, such that the spacer plates are free from interference with the ball of the rod end.

Abstract: The anti-rotation device is composed of an anti-rotation fastener which restrains the rotation of the rod of a rotating star activator. The fastener comprises wall portion and a retaining element (97) which projects inside from the wall portion. The fastener is located between the arms of a clevis (119) so that the retaining elements limit the rotation of the rod between the clevis arms. Independent claims are also included for (a) rotary control system, and (b) method for limiting rotation of axle.

Abstract: The present invention is for an improved rotating control system for use on tilt rotor aircraft and helicopters. Existing rotating control systems usually include a non-rotating swashplate and a rotating swashplate, both swashplates having a plurality of clevises, each clevis formed by at least two clevis arms. The clevis arms are disposed in a clevis plane, and an axis of symmetry is located in the clevis plane between the clevis arms. The devises on the non-rotating swashplate are adapted to pivotally receive an actuator rod which has a rod axis defined by the actuator rod. The apparatus of the present invention includes an anti-rotation clip that is disposed between the clevis arms of each clevis of the non-rotating swashplate. The anti-rotation clip is either of unitary or multi-piece construction. The anti-rotation clip includes a wall portion and at least one restraining member that protrudes inwardly from the wall portion. The restraining members limit the rotation of the actuator rod about the rod axis. This feature prevents wear and structural damage to both the actuator rod and the non-rotating swashplate.
