Abstract
PARA PODER ELIMINAR, POR EJEMPLO, EL JUEGO AXIAL DEL EJE (A) DEL MOTOR (M), DEL ACCIONAMIENTO DE UN REPRODUCTOR DE CD, SE HA PREVISTO UN DISCO (RM) SOBRE EL EJE (A), POR EJEMPLO UN IMAN ANULAR. EL MOTOR (M) ESTA FIJADO A UNA PIEZA DE FIJACION (P) DE METAL, DE FORMA QUE ENTRE EL IMAN ANULAR (RM) Y LA PIEZA DE FIJACION (P), ACTUE UNA FUERZA MAGNETICA, QUE ELIMINE EL JUEGO AXIAL DEL EJE (A). PARA SUPRIMIR TAMBIEN EL JUEGO RADIAL DEL EJE (A) SE HA COLOCADO, EN LA PIEZA DE FIJACION (P), CERCA DEL IMAN DE ANILLO (RM), UN SEGMENTO CIRCULAR (K). MEDIANTE LA FUERZA MAGNETICA QUE ACTUA ENTRE EL SEGMENTO CIRCULAR (K), QUE POR EJEMPLO, PUEDE SER TROQUELADO DE LA PIEZA DE SUJECION (P), Y EL IMAN ANULAR (RM) SE SUPRIME EL JUEGO RADIAL. EL DISPOSITIVO PARA LA SUPRESION DEL JUEGO AXIAL Y RADIAL DE UN EJE, POR EJEMPLO, EL EJE DEL MOTOR DEL GIRADISCOS DE UN REPRODUCTOR DE CD, REPRODUCTOR DE VIDEO, TOCADISCOS DRAW DISC O DE UN APARATO MAGNETO-OPTICO.
