摘要： A hydraulic actuator is disclosed that comprises a first, fixed portion and a second portion movable relative to the first portion. The second portion comprises a hydraulic actuating device for actuating a component, and the actuator further comprises an intermediate member configured to interconnect the first portion with the second portion and permit movement of the second portion relative to the first portion. The intermediate member is configured to convey hydraulic fluid to the hydraulic actuating device of the second portion through a body of the intermediate member.

摘要： A joint for an actuator of a rotorcraft includes a housing configured to be coupled to an input lever of the actuator; and a rotary bearing coupled to the housing, the rotary bearing comprising an inner race and an outer race and configured to be coupled to a control rod, wherein the inner race and outer race are rotationally fixed relative to each other until a torque applied to the joint exceeds a threshold torque value, upon which there is a relative rotatability between the inner race and the outer race.

摘要： A linear actuator arranged to convert rotary motion to linear motion. The linear actuator includes a linear shaft arrangement, having a first shaft portion and a second shaft portion and extends along a longitudinal axis (A) of the linear actuator. At least one of the first shaft portion and the second shaft portion of the linear shaft arrangement can be translated linearly along the longitudinal axis upon actuation. A first drive system has a first rotary component extending at least partially around the longitudinal axis. A second drive system has a second rotary component extending at least partially around the longitudinal axis at a different axial position to the first drive system. The linear actuator, when the first drive system fails, allows rotation of the second rotary component so that the second shaft portion moves relative to the first shaft portion.

摘要： A bearing assembly includes a housing, a spherical bearing located within the housing, and two outer races positioned between the spherical bearing and the housing. The outer races are configured in sliding engagement with the spherical bearing to allow the spherical bearing to rotate relative to the housing. The assembly also includes a tightening element configured to engage a first of the two outer races and tighten the outer races against the spherical bearing. The assembly is configured to provide a primary load path from the tightening element to the housing, wherein the primary load path leads from the tightening element to the housing via the outer races whilst bypassing the spherical bearing.
