Abstract

La ventola (1) รจ realizzata a partire da un foglio di lamiera mediante tranciatura e piegatura; essa presenta una porzione centrale anulare (100) ripartita in sei settori (2) da ciascuno dei quali si estendono una oppure due oppure tre alette (12, 12') ripiegate che fungono da palette.Nella periferia della porzione anulare centrale (100) sono ricavati intagli (5) equidistanti dall'asse e angolarmente equispaziati atti a consentire il passaggio di un utensile (15) orientato parallelamente all'asse della ventola (1) per l'asportazione di materiale dal rotore dell'alternatore al fine di realizzarne l'equilibratura.(Fig. 1).The fan (1) is made from a sheet of metal by cutting and folding; it has a central annular portion (100) divided into six sectors (2) from each of which extend one or two or three folded fins (12, 12 ') which act as pallets. In the periphery of the central annular portion (100) obtained notches (5) equidistant from the axis and angularly equally spaced to allow the passage of a tool (15) oriented parallel to the axis of the fan (1) for the removal of material from the rotor of the alternator in order to achieve its balancing. (Fig. 1).
