ABSTRACT:
A mechanical power transmission apparatus, of the differential gear type, for actuating an airplane control surface requiring two independent actuator inputs to a single control surface. Asymmetric loading to the control surface is accommodated by a mechanical fuse link. The fuse link is provided by employing a shear pin to attach the pinion gear to the pinion shaft, designed to fail at a predetermined differential torque between the two driven bevel gears. Positive disengagement of the gears is provided following fuse link release.
