  • Publication number: 20160319881
    Abstract: The present invention concerns a system for coupling a driving machine with a driven machine comprising a driving machine disk comprising first reliefs, and a driven machine disk comprising second reliefs. The second reliefs are arranged relative to the first reliefs to enable the coupling system to form a first configuration allowing axial separation according to the axis of rotation of the two discs and in which the two disks are in contact, the first reliefs being angularly offset relative to the second reliefs, and a second configuration in which the second reliefs engage with the first reliefs and oppose the axial movement of the two disks relative to each other. The shift from the first to the second configuration is made by a rotation of the two disks relative to each other about the axis of rotation.

  • Patent number: 9431943
    Abstract: The invention relates to electromechanical assemblies comprising an alternator, especially of high power, typically greater than or equal to IMW, and a converter, the alternator comprising a rotor driven in rotation, by a wind turbine for example, and more particularly to wound rotor synchronous alternators. The drive can also take place by means of a tide-driven, hydraulic or marine-current-driven generator. An alternator comprises in a manner known per se a field winding, generally at the rotor, supplied with DC current either by split rings and brushes, or by an exciter, so as to generate in an armature winding, generally at the stator, an AC voltage.
