Abstract

The invention relates to a device for coupling shafts, comprising a coupling part intended to be fitted concentrically into a complementary coupling part said coupling part, comprising two centring zones between which a plurality of splines extend, in which device the splines have a profile which is constant along a median zone, of the coupling part and which in a zone running in the continuation of said median zone, has a smaller thickness by comparison with that in the same spline in the median zone and in which device the splines of said coupling part continue, beyond the zone in which they have a smaller thickness as far as the centring zone which is on the same side of the median zone as said first zone said splines and the spline bottoms, having, in the coupling zone, a profile that continuously couples said splines and the spline bottom to the surface of said centring zone. The invention also relates to a shaft and to a turbo machine comprising such a coupling device.
