ABSTRACT:
A device is disclosed for coupling two shafts for rotating in the prolongation of one another with respect to a casing. A dog clutch ensures that the two shafts are coupled. The device comprises a clutch release uncouple the dog clutch. The clutch release comprises a screw secured to one of the shafts, a nut secured to a flywheel and cooperating with the screw. The screw and nut have an axis coinciding substantially with the axis of rotation of the shafts, and a brake for braking the rotation of the flywheel with respect to the casing, and, in the clutch engagement position, the braking of the flywheel slackens the nut of the screw and drives one of the shafts in translational motion along said axis, so as to uncouple the dog clutch. The structure of the clutch release makes it possible to uncouple the shafts when these are in rotation.
