Abstract

UNA MAQUINA DINAMOELECTRICA QUE TIENE UN ALOJAMIENTO ESTATORICO (12) O CARCASA HECHO POR UN PROCESO DE ESPONJA PERDIDA ES EL QUE SE UTILIZA UN MODELO VAPORIZABLE DE UNA SOLA PIEZA UNITARIO. EL ALOJAMIENTO ESTATORICO PUEDE ESTAR HECHO DE UN METAL FUNDIDO TAL COMO HIERRO O ALUMINIO FUNDIDO, Y TIENE UNA PARED EN FORMA DE ANILLO (14) QUE TIENE INTEGRADAS UNAS ALETAS DE REFRIGERACION LONGITUDINALES SOLIDARIAS EXTENDIDAS HACIA FUERA (24), UNOS ASIENTOS BASE DE MONTAJE (44) Y UN ASIENTO DE SOPORTE DE CAJA DE DERIVACION (60). EL PROCESO DE ESPONJA PERDIDA PERMITE QUE LAS ALETAS DE REFRIGERACION TENGAN UNA MAYOR ALTURA DE ALETA DE REFRIGERACION EFECTIVA EN RELACION AL DIAMETRO DEL ALOJAMIENTO Y UNA MAYOR ALTURA DE ALETA DE REFRIGERACION EFECTIVA EN RELACION AL GROSOR DE LA PARED ANULAR DEL ALOJAMIENTO QUE LA OBTENIDA EN PROCESOS ANTERIORES DE FUNDICION EN ARENA. ESTA MAYOR ALTURA DE LAS ALETAS PROPORCIONA UNA MAYOR RESISTENCIA Y RIGIDEZ A LA PARED ANULAR QUE RADIALMENTE PUEDE HACERSE MAS FINA QUE ALOJAMIENTOS ESTATORICOS O CARCASAS ANTERIORES DE TAMAÑO SIMILAR. SE AHORRA UNA CANTIDAD CONSIDERABLE DE MATERIAL Y DE TRABAJO CON EL ALOJAMIENTO ESTATORICO.
