Abstract
SE PRESENTA UNA TECNICA PARA PREVENIR QUE LOS COJINETES DE BOLAS DE UN DISPOSITIVO DE PEQUEÑO FACTOR DE FORMA SE DAÑEN, EN DONDE EL DISPOSITIVO TIENE AL MENOS UN ANILLO DE RETENCION CONTRA GOLPES DISPUESTO ALREDEDOR DEL EJE Y DENTRO DEL ROTOR DE UN DISPOSITIVO. EL ANILLO TIENE UN TAMAÑO TAL QUE SOLO PERMITE UNA PEQUEÑA CANTIDAD DE MOVIMIENTO DEL ROTOR RESPECTO AL EJE. EL MOVIMIENTO PERMITIDO ES MENOR QUE EL MOVIMIENTO MINIMO QUE PROVOCARIA EL DAÑO DE LOS ELEMENTOS DEL COJINETE DE BOLAS.
