Abstract:
An integrated torque limiter/no-back device for use in an actuator with an input shaft, an output and gear reduction. The device includes an input ramp to receive torque from the input shaft; a combined ramp to transfer torque; an output ramp to transfer torque to the gear reduction; one or more balls between the input ramp and the combined ramp and between the combined ramp and the output ramp to transfer torque; and a brake for causing torque to be grounded and for preventing backdriving of the input shaft by preventing movement of one or more of the input ramp, the combined ramp and the output ramp when a torque threshold has been met. The input ramp and the output ramp are a no-back ramp and a torque limiter ramp, respectively, and the device also includes a pin between the combined ramp and one or more of the no-back ramp and the gear reduction for transferring torque.
