ABSTRACT:
A radially aerated disc rotor is manufactured in such a manner that the inner diameters of the annular discs (8) are greater than the outer diameter of the hub (1, 2) and that the hub (1, 2) is connected with the annular discs (8) which bear a rotor collar (9) by means of canted ribs (4, 5) only. The canted ribs (4,5) serve as bearing, guiding and ventilation elements. Preferably, the canted ribs (4,5) consist of inner (4) and outer (5) portions, their connection preferably being made by welding, preferably within zones of minimum mechanical stress where they are also easily accessible. The disc rotor is particularly suited for large machinery and provides sufficient cooling because of the large area provided for the ingress of cooling air.
