Abstract:
1. A system for uncoupling a first shaft of equipment from a second shaft, the system comprising: a claw coupling including first teeth and first splines so as to be displaced longitudinally along the first shaft by cooperation with second splines carried by the first shaft and to engage or disengage the first teeth on or from second teeth positioned on the second shaft; and an uncoupling device comprising a first fixed part acting on a longitudinally mobile part during uncoupling to displace the claw coupling between a coupled position and an uncoupled position, and an axial translation blocking device, wherein during uncoupling, the uncoupling device transmits a resultant force to the claw coupling, the force being oriented along the axis of rotation of the first shaft and having its point of application located along the axis, and during uncoupling the uncoupling device drives the claw coupling by cooperation of a second part fixed in rotation with a part connected to the claw coupling and driven in rotation therewith, wherein in the coupled position, the axial translation blocking device maintains the claw coupling at a first axial position without the uncoupling device transmitting the force, and a longitudinal clearance is maintained between the second part fixed in rotation and the part connected to the claw coupling and driven in rotation, and wherein in the uncoupled position, the axial translation blocking device maintains the claw coupling at a second axial position without the uncoupling device transmitting the force.
