Abstract: A linear actuator comprising a shaft and a nut that translates within a linear range of motion in response to relative rotation between the nut and shaft, a stop positioned at a travel limiting position and having an inner portion connected to the shaft, a radially compliant outer portion axially overlapping the inner portion and configured to rotate relative to the inner portion, and a cam roller portion disposed radially between the inner and outer portions and configured to move relative to a neutral orientation in response to relative rotation between the inner and outer portions, and the outer portion configured to radially bias the cam roller portion towards the neutral orientation; wherein rotation of the outer portion caused by the nut rotating into the outer portion provides an outward radial load at the cam roller portion on the outer portion that is absorbed by the outer portion.

Abstract: An actuator comprising first and second motors, first and second drive linkages, and a pivot mount configured to pivot about a pivot axis, the pivot mount connected to the first and second drive linkages at first and second mount connections offset first and second offset distances from the pivot axis, the motors and first and second drive linkages configured to provide first and second load paths between a drive housing and the pivot mount so that in a first operation state the pivot mount is in a force-balanced orientation about the pivot axis, and a proximity detector positioned to detect when the pivot mount rotates about the pivot axis above a threshold out of the force-balanced orientation, wherein a force imbalance on the pivot mount caused by a fault in one of the first or second drive linkages above a threshold is detected by the proximity detector.

Abstract: A linear actuator comprising a shaft and a nut in engagement with the shaft such that the nut translates within a linear range of motion axially on a center axis relative to the shaft in response to relative rotation between the nut and the shaft, a stop positioned at a travel limiting position and having a rotational input portion and an axial output portion, the rotational input portion configured to rotate about the center axis relative to the shaft, the axial output portion constrained from rotating about the center axis relative to the shaft and configured to translate axially on the center axis relative to the rotational input portion in response to relative rotation between the axial output portion and the rotational input portion, and an axially compliant member configured to bias the axial output portion towards the travel limiting position.
