SYSTEM FOR ATTACHING THE INTERNAL AIR DEFLECTOR TO A DEFLECTOR CAP FOR A ROTATING ELECTRICAL MACHINE

摘要

The invention consists of a system for attaching the internal air deflector (3) to a deflector cap (1) for a rotating electrical machine, in which this deflector is attached to the deflector cap (1) with attachment element (7) and nut (8) positioned through preferably elongate orifices (3.1) in the flanges (3.2) of the internal deflector (3) and in preferably elongate orifices (1.1) in the deflector cap (1), such that the attachment unit is tightened from the outside of the housing, thereby enabling adjustment of the space (6) between the outer extremity of the blades of the fan (2) and the inside surface of the internal air deflector (3), such as to minimize the effects of the formation of reverse air flows close to the space (6).
