Abstract
UNA LIMA DE DISCO INCLUYE UN ANILLO DE EXPANSION UNIDO A LA PARED DE LA CAMPANA (26) Y LO CUAL ESTA LOCALIZADO ENTRE EL DISCO MAS BAJO (22) DE LA PILA DE DISCOS Y EL REBORDE DE LA CAMPANA. UNA CUCHILLA CIRCULAR (52) CONCENTRICA CON LA CAMPANA ES FORMADA EN EL ANILLO Y ENGANCHA EL LADO DEBAJO DEL DISCO. EL ANILLO ESTA ADAPTADO DE FORMA QUE LA EXPANSION TERMAL DEL ANILLO ES SUSTANCIALMENTE IGUAL AL DISCO DE ALUMINIO EN LA POSICION DE CONTACTO ENTRE LOS DOS. UNA ARANDELA (51) INTERPUESTA ENTRE EL ANILLO Y EL REBORDE PERMITE AL ANILLO MOVERSE LIBREMENTE EN RELACION CON EL REBORDE. DURANTE EL CICLAJE TERMAL, EL ANILLO Y EL DISCO SE MUEVEN A LA MISMA RAZON EN EL PUNTO DE CONTACTO, EL ANILLO ASEGURA QUE LOS DISCOS PERMANEZCAN CONCENTRICOS CON LA CAMPANA A TRAVES DEL RANGO DE LAS TEMPERATURAS DE FUNCIONAMIENTO DE LA LIMA DE DISCO.
