Abstract

UN DISPOSITIVO DE SOPORTE DE ROTACION DE UN ESPEJO POLIGONAL (33) QUE INCLUYE UN EJE ESTACIONARIO QUE CONSTA DE UNA MANGA DE EJE (27) ALREDEDOR DE SU CIRCUNFERENCIA, UN MONTAJE GIRATORIO (R) MONTADO ALREDEDOR DE LA CIRCUNFERENCIA DE LA MANGA DEL EJE Y CON UNA SUPERFICIE RADIAL DE CIRCUNFERENCIA DE UN POLIGONO FABRICADO PARA SERVIR DE SUPERFICIE DE ESPEJO (M) Y CON UN ELEMENTO DE IMAN (47), PLACAS DE PRESION (29/30) PARA SUPRIMIR EL MOVIMIENTO DE UN CONJUNTO ROTATIVO EN DIRECCION AXIAL. EL CONJUNTO ROTATIVO ESTA FORMADO POR UN PRIMER ROTOR (28) MONTADO EN LA CIRCUNFERENCIA EXTERIOR DE LA MANGA DEL EJE (27), UN SEGUNDO ROTOR (33) CON SUPERFICIE DE CIRCUNFERENCIA DE UN POLIGONO FABRICADO PARA SERVIR DE SUPERFICIE DE ESPEJO Y COLOCADO EN LA CIRCUNFERENCIA EXTERIOR DEL PRIMER ROTOR, Y UNA HORQUILLA (31) ASEGURADA EN LA CIRCUNFERENCIA EXTERIOR DEL PRIMER ROTOR. EL PRIMER ROTOR ESTA FABRICADO DE MATERIAL CERAMICO, EL SEGUNDO ROTOR ESTA FABRICADO DE ALUMINIO Y LA HORQUILLA ESTA FABRICADA DE ACERO.SE INCLUYE UN COJINETE RADIAL DE PRESION DINAMICA ENTRE LA CIRCUNFERENCIA EXTERIOR DE LA MANGA DEL EJE Y EL MONTAJE ROTATORIO. LOS COJINETES DE PRESION DINAMICA ESTAN INCLUIDOS ENTRE LAS SUPERFICIES DE LOS EXTREMOS DEL MONTAJE ROTATORIO Y LAS PLACAS DE PRESION.
