Abstract

COJINETE DE FRICCION QUE POSEE UNA CAPACIDAD DE CARGA Y UNA RESISTENCIA A FATIGA MEJORADAS, OBTENIDO POR MEDIO DE LA SINTERIZACION DE UN CUERPO MOLDEADO DE POLVO DE MEZCLA DE METALES CON BASE FERRICA Y,POSTERIORMENTE, LA UNION DEL MISMO A UNA LAMINA DE METAL CON BASE DE ACERO, EN LA CUAL ESTA IMPREGNADO UN ACEITE LUBRICANTE QUE POSEE CONDICIONES DE LUBRICACION OPTIMAS, Y A BASE DE PROPORCIONAR UN MANTENIMIENTO Y UNA GESTION CONVENIENTE DEL MISMO POR MEDIO DE UN PERIODO DE NO SUMINISTRO DE LUBRICANTE INCREMENTADO, Y METODO DE FABRICACION DEL MISMO. EL COJINETE DE FRICCION INCLUYE UNA CAPA DE METAL CON BASE DE ACERO Y UNA CAPA DE ALEACION SINTERIZADA CON BASE FERRICA COMPUESTA POR UN 10 A 30% DE COBRE EN PESO Y EL RESTO, HIERRO. LA CAPA DE ALEACION SINTERIZADA CON BASE FERRICA ES SINTERIZADA, Y, POSTERIORMENTE, UNIDA A LA CAPA DE METAL CON BASE DE ACERO. SE FORMA UN COJINETE DE FRICCION TIPO CASQUILLO INSERTANDO UNA CAPA METALICA CON BASE DE ACERO EN EL MOLDE DE UNA PRENSA QUE POSEE UNA CAVIDAD PARA LA INSTALACION DE UN NUCLEO EN LA ZONA CENTRAL DEL MOLDE Y UN ELEMENTO DE PRENSADO INFERIOR EN LA ZONA INFERIOR DEL MISMO; RELLENANDO CON UN POLVO DE MEZCLA METALICA COMPUESTO POR UN 10 A 30% EN PESO DE COBRE, UN 6,5%, O MENOS, EN PESO DE GRAFITO Y, EL RESTO, HIERRO, LA ZONA ENTRE EL NUCLEO Y LA CAPA METALICA CON BASE DE ACERO Y, A CONTINUACION, INSERTANDO UN ELEMENTO DE PRENSADO SUPERIOR EN LA ZONA SUPERIOR DEL MOLDE; CONFORMANDO EL POLVO DE MEZCLA METALICA EN UN CUERPO MOLDEADO APLICANDO, SELECTIVAMENTE, UNA PRESION DE 50-300 KGF/CM2 AL ELEMENTO DE PRENSADO SUPERIOR Y/O AL ELEMENTO DE PR ENSADO INFERIOR, RESPECTIVAMENTE; Y SINTERIZANDO EL CUERPO MOLDEADO EN UNA CAPA DE ALEACION SINTERIZADA MANTENIENDO EL CUERPO MOLDEADO, JUNTO CON LA CAPA METALICA CON BASE DE ACERO, BAJO UNA ATMOSFERA DE GAS PREDETERMINADA A UNA TEMPERATURA DE 1.065 (GRADOS) C A 1.095 (GRADOS) C DURANTE 3 A 25 MINUTOS Y, POSTERIORMENTE, UNIR LA CAPA DE ALEACION SINTERIZADA A LA CAPA METALICA CON BASE DE ACERO.
