Abstract

EN UN PROCEDIMIENTO DE FABRICACION PARA UNA LEVA DE CONTROL, ELABORADA DE FORMA ESPECIAL CON UN EJE DE LEVAS MONTADO, SE ELABORA UNA LEVA DE CONTROL CON UN CONTORNO PERIMETRICO CON CAPACIDAD DE FUNCIONAMIENTO A TRAVES DE LA ZONA DE LEVA Y DE CIRCULO BASICO CON PREFERENCIA MEDIANTE SINTERIZADO DE FORJA. PARA LA ELEVACION DE LA RESISTENCIA AL DESGASTE SE ENDURECE LA LEVA DE CONTROL. PARA APROVECHAR LAS CONFORMACIONES TERMICAS DE PROCESO, QUE APARECEN A CONTINUACION EN EL CONTORNO PERIMETRICO, SE ELABORA LA LEVA DE CONTROL CON UN CONTORNO PERIMETRICO CONFIGURADO "FALSO" DE TAL MODO QUE SE UTILIZA MEDIANTE LA DEFORMACION TERMICA DE PROCESO DE LA LEVA DE CONTROL, SIENDO CONFORMADO EL CONTORNO PERIMETRICO CON CAPACIDAD DE FUNCIONAMIENTO DE MANERA LIBRE DE MECANIZACION POSTERIOR.
