Couplage curvique pour turbomachine d'aéronef
L'invention vise à maitriser les conséquences d'un désaccouplement sur un mécanisme (47) de couplage denté axial d'un assemblage d'éléments rotatifs (33,35) de turbomachine à gaz. En situation de début de désaccouplement axial on va, par l'intermédiaire d'une excroissan...

| description | L'invention vise à maitriser les conséquences d'un désaccouplement sur un mécanisme (47) de couplage denté axial d'un assemblage d'éléments rotatifs (33,35) de turbomachine à gaz. En situation de début de désaccouplement axial on va, par l'intermédiaire d'une excroissance (51) positionnée sur l'une des dents cannelées de l'assemblage, à l'écart de l'axe (X) d'accouplement, provoquer autour de ladite excroissance un pivotement relatif entre les deux moitiés de couplage. Figure à publier avec l'abrégé : Figure 6.
A toothed coupling mechanism for an assembly of rotating elements of an aircraft gas turbine engine includes a pair of coupling halves having an axial toothed coupling interface therebetween. Each coupling half has a plurality of splined teeth inter-engaged about an axis for transmitting torque therebetween. A protrusion is located on one of the splined teeth of one of the coupling halves. A splined tooth of the other coupling half comes into contact with the protrusion in a situation of uncoupling of said coupling halves. |
