Abstract

Improvements in devices for the adjustable fixation of the axial fan blades of the type in which the blades, by action of elastic elements and centrifugal forces that occur in the service, as well as a blade foot constructed in the form of a the truncated cone with a correspondingly formed clamping part can be fixed in a predetermined position both during stopping and also during operation, characterized in that the angle of inclination of the truncated cone-shaped blade foot and of the clamping piece that it accommodates the latter and the coefficient of friction of the materials used for these as well as the clamping pressure of the blade foot to the clamping piece at the stop and in the service are selected in such a way that an individual regulation and in its blade angle to be made at the stop of the blade wheel, is performed without uncoupling the truncated cone-shaped blade foot from its clamping piece, while an undesired adjustment of the blades caused by torsion and replacement moments that occur in the service, is excluded.
