Abstract: A laminated elastomeric bearing has layers of elastomeric material and layers of metal. A tab is located on a periphery of one of the layers of metal and protrudes from the bearing. A thermoelectric device is coupled to the tab, and heat generated within the bearing during use is conducted to the tab and to the thermoelectric device, allowing for measurement of the heat.

Abstract: According to one embodiment, a pitch link includes a first link, a second link coupled to a first end of the first link, a third link coupled to a second end of the first link opposite the first end, and a first bearing housing having a first bearing and a second bearing housing having a second bearing. The first bearing housing is removably coupled to the second link. The second link separates the first bearing housing from the first link. The second bearing housing is removably coupled to the third link. The third link separates the second bearing housing from the first link.

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

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 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.
