Abstract: A torque transmission system having multiple torque transmission pathways from a driving shaft to a driven shaft. The driving shaft extends from a lower segment to an upper segment via an intermediate segment, the driven shaft extending from a first segment to a second segment. The transmission system includes a nominal spline coupling that is operational in a nominal operating mode, a backup spline coupling between the driving shaft and the driven shaft that is inactive in the nominal operating mode, and a backup radial guide device between the driving shaft and the driven shaft that is inactive in the nominal operating mode.

Abstract: A magnetic device for capturing metal wear particles in suspension in a lubrication fluid, the magnetic device being for inserting in a straight-line insertion direction of the magnetic device into a wall of a casing via a through orifice serving to put an inside volume of the casing containing the lubrication fluid into communication with an outside volume outside the casing, the magnetic device presenting a longitudinal axis X, the longitudinal axis X being for putting into coincidence with the direction for inserting the magnetic device into the casing, the magnetic device comprising a permanent magnet suitable for attracting the metal particles and a presence-detector member for detecting the metal particles attracted by the permanent magnet.

Abstract: A triple circuit lubrication device for lubricating a mechanical system, the lubrication device being provided with two independent lubrication circuits, a tank common to both lubrication circuits and containing a lubrication liquid, and a tertiary circuit in which a tertiary liquid flows. Each lubrication circuit comprises pipes, and respective pressure sensors, pumps, heat exchangers, spray nozzles, and suction points for sucking up the lubrication liquid situated in the tank. The second suction point is situated below the high first suction point. The tertiary circuit comprises a third pump, a third pressure sensor, the second heat exchanger, and a third heat exchanger, thus serving to cool the lubrication liquid flowing through the second lubrication circuit.
