  • Patent number: 11536324
    Abstract: A lubricated rotational connection system provided with a free-wheel having a driving part and a driven part as well as at least one rotational link member arranged in a linking space, the linking space being located radially between a driving linking section and a driven linking section. A lubrication device comprises a fluid circulation device constrained to rotate with a driven pumping section of the driven part. The fluid circulation device is set in rotation with respect to a driving pumping section when the driving speed of rotation of the driving pumping section is lower than the driven speed of rotation of the driven pumping section about the axis of rotation in order to generate a forced circulation of the lubricating fluid within the linking space.

  • Patent number: 11435029
    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.

  • Patent number: 10267367
    Abstract: A coupling means having a first member provided with a first diaphragm and a second member provided with a second diaphragm. The coupling means include an additional device having a plurality of protrusions circumferentially distributed on a first cylinder of the first member and a plurality of abutments distributed circumferentially on a second cylinder of the second member, each protrusion presenting at least one sliding face facing a first bearing face of an abutment, each protrusion presenting a blocking face facing a face of the second member referred to as a “second bearing” face.
