ABSTRACT:
A device for connecting in rotation two substantially coaxial elements (10,12), of the type comprising a splined shaft (10,20), a splined hub (24) and clamping elements for achieving a relative axial immobilization between the splined shaft and splined hub. A first end portion of the splined shaft (20) is provided with a centering ring (30) having an outer surface (34) including an outer screw threading (36) having unsymmetrical flanks, which ring (30) is screw-threadedly mounted in a corresponding portion (42) of the splined hub (24) comprising a complementary tapping (44) having unsymmetrical flanks. The second end portion (46) of the splined shaft (20) comprises an outer screw threading (48) on which is screw-threadedly mounted an axial clamping nut (50) having a radial face (52) cooperating with a confronting radial face (54) on the splined hub (24). The invention is of utility in connecting in rotation a power shaft and a rotating element of a turbomachine.
