A torque limiter limits transmission of torque between an input shaft an output shaft. The torque limiter may be incorporated in a geared rotary actuator for actuating an aircraft control surface. The torque limiter is responsive to output torque associated with the output shaft instead of input torque associated with the input shaft. The torque limiter includes a structural ground and a gear assembly for transmitting rotational motion of the input shaft to the output shaft. The gear assembly includes a reference gear coupled to the structural ground such that movement of the reference gear relative to the structural ground is dependent upon an output torque at the output shaft. The reference gear is stationary relative to the structural ground when the output torque is below an output torque limit, and the reference gear moves relative the structural ground when the output torque exceeds the output torque limit. |
