Abstract

DISPOSITIVO DE BLOQUEO AUTOMATICO PARA ACOPLAMIENTOS SOMETIDOS A ESFUERZOS MECANICOS INDESEABLES.COMPRENDE UN TRANSDUCTOR (10) FIJADO RIGIDAMENTE A LAS ESTRUCTURAS MECANICAS EN LAS QUE SE DISPONE EL ACOPLAMIENTO, PARA EMITIR UNA SEN/AL ELECTRICA QUE ES UNA FUNCION DEL ESFUERZO MECANICO RECIBIDO, Y UNA BOBINA (13) ALIMENTADA POR DICHO TRANSDUCTOR PARA GENERAR UN CAMPO ELECTROMAGNETICO QUE OCASIONA EL BLOQUEO DEL ACOPLAMIENTO. DICHA BOBINA ESTA CONECTADA FUNCIONALMENTE CON EL ACOPLAMIENTO PARA PODER ACTUAR SOBRE EL, EN OPOSICION AL MOVIMIENTO DE ESTE ULTIMO.
