Document Type and Number:
WIPO Patent Application WO/2013/136020
Kind Code:
A3
Abstract:
The invention relates essentially to an assembly of flanges (55, 56) for supporting at least one bundle (36) of sheets and coil chignons (50) arranged axially on either side of the bundle (36) of sheets of a rotor of a rotary electric machine, each supporting flange (55, 56) comprising: - a radial wall (59) provided with a main opening enabling a shaft (35) of the rotor to pass therethrough; - an annular sill (75) extending at the outer periphery of the radial wall (59), axially towards the rotor, said annular sill (75) having one surface resting on the outer radial end surface of the bundle (36), at least one of the supporting flanges (55, 56) also comprising at least one heat-discharge and centring pin (77) positioned such as to engage with an axial opening (66) made in the bundle (36) of sheets, said heat-discharge and centring pin (77) being suitable for discharging the heat from the bundle (36) of sheets to the flange (55, 56). The rotor of the rotary electric machine comprises such an assembly.
