Abstract:
1. A coupling device for end-to-end coupling between a supercritical transmission shaft and link shafts between which the transmission shaft is interposed, the coupling device comprising: coupling means for flexible end-to-end coupling between the ends of the transmission shaft and respectively with one and the other of the link shafts, providing freedom to move in angular deflection (B) about centers of motion (C damper means for damping the movement in angular deflection (B) of the transmission shaft relative to the axes of the link shafts; and at least one bearing for mounting the transmission shaft at one of its ends on a carrier structure, the bearing comprising a cage that houses at least one rolling member interposed between the transmission shaft and the carrier structure, wherein for a given bearing, the geometrical center (C wherein the damper means comprise at least one pair of friction members having spherical bearing surfaces that are incorporated in the bearing and placed to press one towards the other via respective friction surfaces, a first friction member being securely engaged with the carrier structure and a second friction member being securely engaged with the cage, itself engaged on the transmission shaft to accompany it in its movement in angular deflection (B).
