ABSTRACT:
To improve the reliability of a fan blade to provide forced cooling to automotive-type alternators, while retaining the advantages of compact construction and inexpensive manufacture, a disk-shaped element is formed with a central opening to receive the shaft of the alternator having fan blades at the periphery thereof, and which further is so shaped and formed that the central region is axially (with respect to the shaft) offset from the major plane of the disk-shaped fan blade, clamping washers being placed against the offset region, one washer spanning the concave portion of the offset portion and the other washer fitting within the concave portion of the offset.
