A flange (6) for coupling a cylindrical element (4) to be driven at a high rotational speed with an inner, and coaxial, rotating axle (2), comprising a first cylindrical inner part (26) connected with the axle, and connected via a connecting part (12), to a cylindrical radially outer part (20, 10) which bears the cylindrical part (4), with which it is intended to accomplish to retain a good contact, also at high rotational speeds, between this outer surface (10) and the rotor (4) carried on it. For this purpose the connecting part (6) in the invention is formed by two disc-shaped parts (14, 16) situated at a distance from one another in an axial and radial direction, the outermost (14) of which is connected to the outer part (20) via an essentially right-angled transition, the innermost (16) of which is connected to the inner part (26) via an essentially right-angled transition, and which are connected to one another via an intermediary part (24) via an essentially right-angled transition.
A coupling flange device for connecting a high rotational speed cylindrical element (4) to a coaxial rotating axle (2) comprising a first cylindrical inner part (8) for connection to the axle (2), a connecting part (12) interconnecting said first cylindrical inner part (8) to a cylindrical outer part (10), the cylindrical element (4) being disposed radially outwardly of said cylindrical outer part (10) and being attached thereto, said connecting part (12) comprising first and second disc-shaped parts (14,16) which are axially and radially spaced from each other such that said first part (14) is radially outwardly of said second part (16), an intermediate part (18) connecting said first and second disc-shaped parts and comprising a pair of first and second right-angle transition members (22,24), a third right angle transition member (20) connecting said first disc-shaped part (14) to said cylindrical outer part (10), a fourth right angle transition member (26) connecting said second disc-shaped part (16) to said first cylindrical inner part (8), said first disc-shaped part (14) being connected only to the cylindrical outer part (10) of said inner and outer cylindrical parts (8,10) and said second disc-shaped part (16) connected only to the first cylindrical inner part (8) of said inner and outer cylindrical parts (8,10), said first, second, third, and fourth right angle transition members and said first and second disc-shaped parts defining an S-shaped member connected only to said inner (8) and outer (10) cylindrical parts.
