ASSEMBLY OF FLANGES OF THE ROTOR OF A ROTARY ELECTRIC MACHINE COMPRISING AXIAL VENTILATION BLADES PROMOTING AN AXIAL AIR FLOW INSIDE THE ROTOR, AND RELATED ELECTRIC MACHINE ROTOR

摘要

The invention relates essentially to an assembly of flanges (55, 56) for supporting at least one bundle of sheets and coil chignons arranged on either side of the bundle of sheets of a rotor of a rotating electric machine, each supporting flange (55, 56) comprising: a radial wall (59) provided with a main opening (60) enabling a shaft (35) of the rotor to pass therethrough; an annular sill extending at the outer periphery of the radial wall (59) and extending axially towards the rotor, said annular sill having one surface resting on the relevant outer radial end surface of the bundle of sheets; at least one of the supporting flanges (55, 56) also comprising at least one axial ventilation blade (71) connected with a through opening (72) made in the radial wall (59), said axial ventilation blade being intended for ensuring an axial circulation of the air flow in the rotor.
