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 damping arrangement for an electromechanical actuator including an actuator member and a lubricant fluid for lubricating the actuator member during movement of the actuator member. The damping arrangement comprises a constrained passage, the constrained passage configured to restrict a flow of the lubricant fluid in order to provide a damping force to resist a movement of the actuator member during a failure event.

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 connector for adjustably connecting an RVDT (rotary variable differential transformer) and a reductor shaft. The connector includes a body defining a bore configured to receive the reductor shaft. The bore has an inner wall and a threaded tightening member which is substantially parallel to a main axis (AA, BB) of the bore. A portion of the body is configured to deform upon tightening of the tightening member such that, when the reductor shaft is received by the bore, the reductor shaft is gripped by at least a portion of the inner wall.

摘要： There is provided an actuator comprising screw shaft and a nut assembly. The nut assembly comprises a primary nut for transmitting load through the actuator along a primary load path, and a secondary nut for transmitting load through the actuator along a secondary load path. The secondary nut comprises first and second portions movable relative to one another. As load is transmitted through the actuator along the primary load path the secondary nut does not transmit load through the actuator, wherein upon failure of the primary load path the first and second portions move relative to each other, such relative movement causing the first and second portions to engage the screw shaft and enable transmittal of load through the secondary nut of the actuator along the secondary load path.

摘要： An attachment assembly for connecting an actuator to a frame, a method for manufacturing this attachment assembly and a method for reducing backlash in an attachment assembly. The attachment assembly comprises: an outer yoke having a first end and an opposite second end and defining an internal cavity at said second end. The outer yoke has an aperture provided at its second end connected to the cavity; and an inner yoke located within the cavity. A tie bar having a ball shaped end extends through said aperture such that the ball shaped end is positioned within the cavity and cannot pass through the aperture. A spring is provided at said first end of said outer yoke that is configured to bias the inner yoke in the direction of the aperture. The attachment also includes shearable means for holding the inner yoke.
