Abstract

METODO PARA FABRICAR UN ENGRANAJE HELICOIDAL QUE PERMITE COLOCAR ESTRATEGICAMENTE UNA CAPA DE ELEVADA DUREZA Y RESISTENTE AL DESGASTE EN UNAS POSICIONES PREDETERMINADAS DEL ENGRANAJE. EL METODO INCLUYE LAS FASES DE FORMAR (24) UN NUCLEO DE ENGRANAJE PREMOLDEADO QUE TIENE UNA FORMA GENERAL DE ENGRANAJE HELICOIDAL Y SITUAR (26) EL NUCLEO DE ENGRANAJE PREMOLDEADO DENTRO DE UN MOLDE ELASTOMERICO QUE TIENE LA FORMA ESPECIFICA DE ENGRANAJE HELICOIDAL. EL METODO TAMBIEN INCLUYE LAS FASES DE RELLENAR (26) EL MOLDE EN LAS POSICIONES PREDETERMINADAS CON UN MATERIAL METALURGICO ENDURECIBLE Y CONDENSAR (28) EL NUCLEO DE ENGRANAJE PREMOLDEADO Y EL MATERIAL METALURGICO. FINALMENTE, EL METODO TAMBIEN INCLUYE LA FASE DE TRATAR AL CALOR (30) EL NUCLEO DE ENGRANAJE PREMOLDEADO Y EL MATERIAL METALURGICO, PARA OBTENER UN ENGRANAJE HELICOIDAL QUE TIENE UNA CAPA RESISTENTE AL DESGASTE EN POSICIONES PREDETERMINADAS. TAMBIEN SE PREVE UN ENGRANAJE HELICOIDAL (10) FORMADO DE ACUERDO CON ESTE METODO.
