Title (EN) MANUFACTURING PROCESS OF A HEAD CYLINDER PROVIDED WITH COOLING OR REINFORCING CORRUGATIONS
(FR) PROCEDE DE FABRICATION D"UN CYLINDRE DE TETE MUNI D"ONDULATIONS DE REFROIDISSEMENT OU DE RENFORCEMENT
Abstract:
(EN) For the manufacturing of a stator body (4) of an air cooled electric machine, all the cooling and reinforcing radial ondulations which extend axially, are formed in a single pressing operation applied to sheet metal (43). This method is more rational than the conventional step by step method.
(FR) Pour la fabrication d"un corps de stator (4) d"une machine electrique refroidie a l"air, toutes les ondulations radiales de refroidissement et de renforcement qui s"etendent axialement, sont formees dans une unique operation de pressage appliquee a une tole (43). Ce procede est plus rationnel que le procede conventionnel pas-a-pas.
