Abstract
A linear electro-mechanical actuator assembly includes a linear actuator having an output rod end, and a bell crank assembly having a bell crank that is rotatable around a central axis and that has a rod connection opening for receiving the rod end. The bell crank further includes a tube opening along the central axis for receiving a torque tube. First and second bearing plates are positioned on opposite sides of the bell crank, whereby the bank crank rotates relative to the first and second bearing plates. A connection pin provides a hinge connection of the rod end to the bell crank such that linear motion of the rod end imparts rotational motion to the bell crank. The bell crank includes bearing supports positioned on opposite sides of the bell crank body. Circular bearings are positioned within the bearing plates, and around the bearing supports, to support the rotational motion of the bell crank.
