A mechanical transmission device having a planet carrier and at least two planets mounted on the planet carrier by means of respective rotation shafts. The device includes a stop for stopping movement of the various rotation shafts in axial translation.

Mechanical transmission device

The invention relates to a flight control device for an aircraft, the device comprising a mount, a lever pivotally mounted on the mount, and mechanical means for generating a return force for the lever, said means including a spring and a first motor member that are arranged so that a first end of the spring is constrained to move in rotation with the lever and a second end of the spring is constrained to move in rotation with an outlet shaft of the first motor member. According to the invention, the flight control device includes an electrical assistance system for assisting said mechanical means for generating a return force.

Flight control device for an aircraft

Device for transmitting movement to a toothed element forming an input of a position sensor, the transmission device including an output shaft, a first toothed sector rotatably linked to the output shaft and a second toothed sector mounted coaxially to the first toothed sector in order to have an angular displacement relative to the first toothed sector, a return member mounted between the toothed sectors returning the second toothed sector into a predetermined position, characterised in that the return member is arranged such as to magnetically generate a force tending to move the second toothed sector into the predetermined position.

Device for transmitting movement to a position senser and corresponding device for sensing position

An electromechanical actuator comprising a frame having mounted thereon a rotary motor and a gear train having an inlet shaft lying on the same axis as an outlet shaft of the motor and connected thereto, and an outlet ring coaxial with the outlet shaft of the motor and connected to a lever for operating a member that is to be driven. The gear train is carried by a casing mounted on the frame to pivot about the axis of the outlet shaft of the motor. An anti-blocking device is mounted on the frame and comprises a movable element that is movable between a blocking position for blocking the casing in rotation relative to the frame, and a release position for releasing the casing in rotation relative to the frame.
