Abstract

SE DESCRIBE UN PERNO (2) DEL TIPO QUE POSEE UN EXTREMO FORMADO POR UN ORIFICIO ROSCADO Y UN SEGUNDO EXTREMO FORMADO POR UNA ROSCA EXTERNA (22), CONOCIDO COMO "PERNO HEMBRA", JUNTO CON UN METODO PARA FORMAR DICHO PERNO (2). EL METODO CONSISTE EN LOS PASOS DE HORADAR UN ORIFICIO ROSCADO A TRAVES DE LA LONGITUD DE UNA VARILLA PRIMERA (4), FORMAR UNA ROSCA EXTERNA (22) EN AL MENOS UN EXTREMO DE UNA SEGUNDA VARILLA (6), Y CONECTAR AMBAS VARILLAS ATORNILLANDO EL PRIMER EXTREMO DE LA SEGUNDA VARILLA (6) EN EL ORIFICIO ROSCADO INTERNO DE LA PRIMERA VARILLA (4). EL EXTREMO DEL ORIFICIO DE LA PRIMERA VARILLA (4) A LA QUE SE CONECTA LA SEGUNDA VARILLA (6) ESTA DOBLEMENTE AGUJEREADO PARA FORMAR EN SU INTERIOR UNA ROSCA (12) DE PASO MAS FINO SEGUNDO. LAS ROSCAS SE COLOCAN DE MODO QUE LA RETIRADA DEL PERNO DE UNA PARTE A LA QUE ESTA ATORNILLADO EL EXTREMO SEGUNDO LIBRE DE LA PRIMERA VARILLA PROVOCA LA TENSION DE LA CONEXION DE TORNILLO ENTRE LAS DOS VARILLAS.DESCRIBES A BOLT (2) OF THE TYPE THAT HAS AN END FORMED BY A THREADED HOLE AND A SECOND END FORMED BY AN EXTERNAL THREAD (22), KNOWN AS "FEMALE BOLT", TOGETHER WITH A METHOD FOR FORMING SUCH BOLT (2). THE METHOD CONSISTS OF THE STEPS OF BORING A THREADED HOLE THROUGH THE LENGTH OF A FIRST ROD (4), FORMING AN EXTERNAL THREAD (22) IN AT LEAST ONE END OF A SECOND ROD (6), AND CONNECTING BOTH RODS BY SCREWING THE FIRST END OF THE SECOND ROD (6) IN THE INTERNAL THREADED HOLE OF THE FIRST ROD (4). THE END OF THE HOLE OF THE FIRST ROD (4) TO WHICH THE SECOND ROD (6) IS CONNECTED IS DOUBLE HOLED TO FORM A THREAD (12) OF FINER SECOND PASS INSIDE. THE THREADS ARE PLACED SO THAT THE REMOVAL OF THE BOLT FROM A PART TO WHICH THE EXTREME SECOND FREE OF THE FIRST ROD IS SCREWED CAUSES THE TENSION OF THE SCREW CONNECTION BETWEEN THE TWO RODS.
