Abstract
Fan enclosure, characterized by comprising a number of pallets equal to each other, each of which are constituted by a piece of stamped metal plate, which is applied and fixed on a support also stamped metal plate, which conform a housing in which it fits a cylindrical shank, which is fixed rigidly in the assembly position, in which it protrudes from the base of the assembly, being able to adjust and be trapped between a pair of matching radial races provided on the facing faces of two corresponding plates that are applied against each other and are fixed to each other in this position, constituting the central core through which the assembly of the impeller on the motor shaft is carried out; with the characteristic that the fixation between these two plates is carried out by means of a series of screws that pass through them, each of which goes through a diametral perforation in the same one practiced for this purpose, the mounting rod of a of the referred pallets; so that the orientation adopted by this diametrical perforation with respect to the stem determines the orientation adopted by the corresponding pallet with respect to the core.
