摘要

The cooling fan (3) consists of a propeller (4), mounted on a shaft (6) and driven in rotation around an axis (A). The propeller is mounted on the primary end (12) of the shaft, by means of a support collar (13), which is rigidly fixed to the primary end of the shaft, and a bolt (20). The support collar extends externally from the end of the shaft and forms an axial support bearing for the propeller.
