Abstract

EN UN DISPOSITIVO DE FIJACION, UN MATERIAL CENTRAL DE UN MIEMBRO ROTATORIO DE FIJACION TIENE UNA PORCION DE DIAMETRO MAS AMPLIO ENTRE UNA PORCION CENTRAL Y CADA PORCION DEL EXTREMO EN UNA REGION DONDE UN MATERIAL DE GRABACION TRASPASA EL TAMAÑO MAS AMPLIO, Y EL DIAMETRO DEL MATERIAL CENTRAL ES GRADUALMENTE REDUCIDO DESDE LA PORCION DE DIAMETRO MAS AMPLIO HACIA EL INTERIOR Y EL EXTERIOR. LA FORMA EXTERIOR DEL MIEMBRO ROTATORIO DE FIJACION SE CONFORMA A LA HECHURA DEL MATERIAL CENTRAL. DE ACUERDO A ESTA CONFIGURACION, ES POSIBLE PREVENIR LA CORRUGACION Y RIZADO DEL MATERIAL DE GRABACION, Y PROPORCIONAR EXCELENTE ELEVABILIDAD DEL MATERIAL DE GRABACION.
