Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO ASI COMO A UN DISPOSITIVO PARA EL APRIETE O EL AFLOJAMIENTO --CONTROLADOS POR EL ANGULO DE GIRO-- DE LOS ATORNILLAMIENTOS REALIZADOS POR MEDIO DE UN ATORNILLADOR; EN ESTE CASO, ES MEDIDO EL ANGULO DE GIRO ABSOLUTO, QUE DURANTE EL ATORNILLAMIENTO ES SOBREPASADO CON RESPECTO A UN PUNTO FIJO, POR UN EJE DE GIRO QUE ES PARALELO RESPECTO A UN PUNTO FIJO, POR UN EJE DE GIRO QUE ES PARALELO AL EJE DE ROTACION DEL ATORNILLAMIENTO. UNA CONVENIENTE MEDICION ABSOLUTA --LIBRE DE UNA POSICION RELATIVA-- DEL ANGULO DE GIRO ES REALIZADA POR LA DETERMINACION DE LA BASE DE REFERENCIA PARA EL TRANSMISOR DE ANGULO MEDIANTE EL EMPLEO DE UN SENSOR DEL NUMERO DE GIROS DE UNA MEDICION ABSOLUTA. EN ESTE CASO, EL SENSOR DEL NUMERO DE GIRO PUEDE ESTAR REALIZADO COMO UN GIROSCOPIO MECANICO AL ESTILO DE COMPAS, COMO UN SENSOR DE ROTACION O BIEN EN LA FORMA DE UN SENSOR DE ACELERACION POR MEDIO DEL CUAL PUEDE SER REGISTRADO UN VALOR DE MEDICION QUE ESTA EN CORRELACION CON EL ANGULO DE GIRO ABSOLUTO.
