摘要： An electromechanical actuator comprises: a motor; a gearbox; an anti-extension device mounted between the motor and the gearbox. The motor and anti-extension device are mounted on a housing of the actuator. The actuator further comprises a screw shaft; a nut mounted on the screw shaft; an output rod connected to the nut, the output rod having a linear range of motion defined between full extension of the output rod at a first end point (A) and full retraction of the output rod at a second end point (C). The screw shaft, nut, and output rod are located in a cavity of the housing. The output rod and nut are held against rotation relative to the housing, such that rotation of the screw shaft drives the output rod to move linearly within the housing.

摘要： An actuator system includes a motor and an actuator positioning member to be driven by the motor from a start position to an actuated position. The system also includes a harmonic drive assembly between the motor and the actuator positioning member arranged to transfer torque from the motor to the actuator positioning member at a gear ratio of greater than 1:1. The system further includes means for disconnecting the harmonic drive assembly in response to failure of the motor and/or torque transfer such as to allow the positioning member to return to the start position.

摘要： A method of manufacturing a gear includes: providing a shaft; forming a groove into the shaft; and inserting a tooth into the groove such that the tooth is retained in the groove by an interference fit. A retainer can also be fixed to the shaft such that the tooth is retained in the groove by the retainer in addition to the interference fit.

摘要： A wing panel actuator assembly includes: an actuator housing; an actuator piston arranged in the actuator housing and axially movable relative to the actuator housing; a connecting rod attached, at one end, to an end of the piston extending from the actuator housing; the actuator housing and piston arranged to be accommodated inside a movable panel of an aircraft wing. The connecting rod is arranged to be attached, in use, at its end opposite the one end attached to the piston, to a wing structure of the aircraft wing, the panel being pivotable about a pivot point P relative to the wing structure by means of the actuator piston.

摘要： A gear device for a gear system for an aircraft includes: an input stage epicyclic gear comprising an input stage sun, an input stage carrier and an input stage ring; and an output stage epicyclic gear comprising an output stage sun, an output stage carrier and an output stage ring. A first input stage component of the input stage sun, the input stage carrier and the input stage ring is fixed to a corresponding first output stage component of the output stage sun, the output stage carrier and the output stage ring, wherein a second input stage component of the input stage sun, the input stage carrier and the input stage ring is fixed to a corresponding second output stage component of the output stage sun, the output stage carrier and the output stage ring. The second input stage component is different from the first input stage component.

摘要： An electromechanical actuator (EMA) includes a plurality of modes and includes an electrical motor having a motor shaft extending along an axis (A) and that drives the shaft to rotate about the axis and a gear assembly mounted around, and in geared connection with the shaft, to rotate with the shaft. The EMA output is connected to the gear assembly such that rotation of the motor shaft causes rotation of the output via the gear assembly, the output rotating at a speed which is a predetermined fraction of the speed of rotation of the motor shaft based on the gear ratio of the gear assembly. The EMA also includes a synchroniser comprising a first conical portion connected to an end of the motor shaft, and a second conical portion connected to a ratchet. The synchroniser has an engaged position and a disengaged position.

摘要： A flight control surface actuation system includes a rotary actuator having an output part configured to rotate about an axis (R-R), a connecting rod for connecting a flight control surface to the rotary actuator, and a connection mechanism connecting a first end of the connecting rod to the output part such that rotation of the output part about the axis causes at least part of the connection rod to rotate about the axis. The connection mechanism comprises a connection structure fixed to the output part and an engagement part mounted for rotation about a longitudinal axis. The engagement part extends through the connecting rod and is fixed to it. A position sensor is arranged to measure the angular displacement of the first end of the connecting rod about the axis.

摘要： An asymmetric torque limiter having an axis of rotation including a first annular friction disk, a second annular friction disk a skewed roller disk a first resilient member and a second resilient member. The second annular friction disk is concentrically arranged with the first annular friction disk. The skewed roller disk is in contact with the second annular friction disk. The skewed roller disk includes a plurality of skewed rollers mounted in an annular retainer. The plurality of skewed rollers are about a respective roller axis, each roller axis being skewed to a radial direction passing through the skewed roller from the axis of rotation. The first resilient member is attached to the first annular friction disk and is configured to bias the first annular friction disk toward an input shaft. The second resilient member is configured to bias the skewed roller disk toward the second annular friction disk.
