Abstract (en)
[origin: EP1862642A2] A rotor for traction engines, in particular of a first phase of a vapor turbine, comprising a series of blades (12) arranged circumferentially on the rotor by the interposition of a base portion (18) formed in a single piece with the blades (12), on the opposite portion of the blades (12) with respect to the base portion (18), one or more covering belts (24) also being envisaged which group the blades (12) of the rotor in packs. The blades (12) and the covering belts (24) are coupled by the riveting of pins (26) integrated with the blades (12), and the coupling between the base portion or foot (18) of the blades (12) and the main body or disk (22) of the rotor is effected by fork insertion in the radial direction of the rotor.
