Patent abstract
The invention relates to a device for coupling two shafts intended to rotate in the continuation of one another about an axis. The device comprises a dog clutch allowing the driving shaft to drive the driven shaft, and declutching means allowing the dog clutch to be uncoupled from a clutch-engaged position to a declutched position. The declutching means comprise at least one first channel secured to a driving element of the dog clutch, the first channel having the shape of a portion of a torus about the axis, at least one second channel secured to the driving shaft, the second channel having a helical shape about the axis element intended to roll between the first and in the second channel.
