Abstract
An integrated torque limiter/no-back device for use in an actuator with an input shaft, an output, and a gear reduction. The device includes an input ramp, an output ramp coupled to the gear reduction, a combined ramp disposed between the input ramp and the output ramp, a first plurality of balls arranged between the input ramp and the combined ramp, a second plurality of balls arranged between the combined ramp and the output ramp, a pin, and a brake. The pin extends from the input ramp to the combined ramp and coupled to the input shaft. The combined ramp, the output ramp, and the second plurality of balls therebetween are configured to operate as a torque limiter by causing the combined ramp and the output ramp to separate and the output ramp to engage the brake when the torque from the input shaft exceeds a torque threshold.
