Abstract
EL INVENTO OFRECE UN PROCEDIMIENTO Y UN DISPOSITIVO PARA PRODUCIR UNA VARIACION DE FLANCOS DENTADOS, ES DECIR, PARA VARIAR LA FORMA DE LOS FLANCOS DENTADOS DE LOS ELEMENTOS ACOPLADORES DE UN ENGRANAJE, FABRICADOS CON METALURGIA DE POLVO. EN EL ESTADO ACTUAL DE LA TECNICA, SE PROPONE QUE TALES MUTACIONES SE MECANICEN CON ARRANQUE DE VIRUTAS POR MEDIO DE UNA PIEZA SINTERIZADA, PORQUE ESTO NO ES FACTIBLE POR LA ACCION DEL POLVO DE LOS ELEMENTOS DE MOLDEO. ES COHERENTE QUE EL MODELO CONSIGA LA MUTACION DE LOS FLANCOS POR MEDIO DE CONFIGURACIONES DISTENSAS EN UN UTIL PARA PRENSAR, Y SEA MODIFICADO EN UNA HERRAMIENTA DE RECALIBRADO. LA VENTAJA DEL PROCEDIMIENTO RADICA EN SU ECONOMIA, TANTO RESPECTO A LOS ELEMENTOS DE ENGRANAJE OBTENIDOS PURAMENTE POR DESVIRUTADO, COMO A LOS OBTENIDOS POR MEDIO DE METALURGIA DE POLVO O A LOS RETOCADOS POR MEDIO DE VIRUTADO. UNA APLICACION PREFERENTE ES EL PERFECCIONAMIENTO DE LA RECTIFICAION DE LOS FLANCOS EN FLANCOS DENTADOS DE ANILLOS SINCRONIZADOS PARA CAMBIOSDE MARCHA-KFZ.
