Flange coupling with radial disc-shaped flange and axial hub

摘要

The coupling comprises a disc-shaped flange which extends radially to the coupling axis. It further comprises a hub (7) axially spaced from the central section, with cylindrical inner-surface (11) and conical outer-surface (16). The angle ( alpha ) between the conical outer-surface of the hub or conical inner-surface (31) of the clamping ring (8) on the one hand, and the coupling axis, on the other hand is between 1 to 3 deg.. The distance (A) of the part-circle (9) of the tensioning screws (10) is equal to the distance (A1) of part-circle of tensioning ring outer-surface (32).
