Abstract

The invention aims to prevent the blockage of air passages in the curvic couplings between drive parts and also to prevent the potential damage to said drive parts during weakening of protective elements. To this end, the invention envisages the formation of axial abutments by the ring gears of the curvic couplings. A coupling, according to the invention, comprises two rings (22, 24), each ring being on the end of one drive part (12,14) and engaged with the other so as to transmit to said drive part a rotation around a central axis (X'X) while allowing air (F2, F4) to pass between the male and female portions of the teeth of the rings behind a bearing area Za. The rings (22, 24) are extended in an at least partially radial manner relative to each other such as to form an outer ring extension (22e) and an inner ring extension (24i) respectively facing the elements (19,16) surrounding the drive part (14, 12) that is mounted onto the other ring (24, 22). The invention is of use in the rotor lines of turbine engines.
