Abstract

UN EMBRAGUE (36) ACCIONADO POR UN ELECTROIMAN FIJO (56), CON UNA PLACA DE NUCLEO PLANO (66) QUE TIENE UNA SERIE DE RANURAS ARQUEADAS (70, 72), TIENE UN ROTOR DE HIERRO FUNDIDO DE UNA SOLA PIEZA QUE TIENE PARTES CILINDRICAS INTERIOR Y EXTERIOR (12, 22) UNIDAS EN UN EXTREMO MEDIANTE UNA PARTE RADIAL DE EMBRAGUE (14) QUE TIENE UNA SERIE DE RANURAS ARQUEADAS (16, 18, 20) QUE SE ABREN EN LA SUPERFICIE DE ENGANCHE AL NUCLEO (26). EL ROTOR SE FABRICA EN UNA SOLA PIEZA FUNDIDA DE HIERRO FUNDIDO (10) QUE SE MAQUINA LIGERAMENTE PARA SUMINISTRAR LA SUPERFICIE DE ENGANCHE AL NUCLEO (26) Y LAS SUPERFICIES DE HUELGO (32, 34) DEL ELECTROIMAN. SE ESPECIFICA UNA COMPOSICION PREFERIDA DEL HIERRO FUNDIDO.
