Abstract

SENSOR DE FUERZA (1) ADECUADO PARA SE USADO EN UN DISPOSITIVO DE PESADA, QUE CONSTA DE UN BLOQUE PARALELEPIPEDICO (2). HAY AL MENOS UN AGUJERO TRANSVERSAL (6) EN EL BLOQUE, QUE DEFINE UNA COLUMNA VERTICAL FIJA Y UNA COLUMNA VERTICAL MOVIL. HAY TAMBIEN UNOS TRAVESAÑOS HORIZONTALES (7 Y 8) DEFINIDOS POR EL AGUJERO, ACOPLANDOSE A LAS COLUMNAS MENCIONADAS Y FORMANDO CON ELLAS UN PRIMER PARALELOGRAMO DEFORMABLE VERTICAL. LOS SENSORES DE DEFORMACION SE FIJAN A AL MENOS UN PAR DE AREAS DE SECCION TRANSVERSAL REDUCIDA SOBRE DICHO TRAVESAÑO HORIZONTAL. LA COLUMNA VERTICAL FIJA ESTA FIJA RIGIDAMENTE A UNA BASE. SE ACOPLA UN PLATO RECEPTOR MEDIANTE UN SISTEMA AMORTIGUADOR (5) A LA COLUMNA VERTICAL MOVIL. DICHO SISTEMA CONSTA DE UN BASTIDOR VERTICAL QUE FORMA UN SEGUNDO PARALELOGRAMO DEFORMABLE ELASTICAMENTE EN EL PLANO VERTICAL. ES MENOS RESISTENTE QUE EL PRIMER PARALELOGRAMO DEFORMABLE E INCORPORA DOS LADOS VERTICALES (13 Y 27) FIJOS RESPECTIVAMENTE A LA COLUMNA VERTICAL MOVIL Y AL PLATO RECEPTOR,Y DOS HOJAS HORIZONTALES (23) QUE ACOPLAN DICHOS LADOS VERTICALES. EL LADO VERTICAL ACOPLADO AL PLATO RECEPTOR ES MOVIL SIN NINGUN CONTACTO DIRECTO CON EL BLOQUE, Y CONSTA DE DOS TRAVESAÑOS MOVILES VERTICALES (27) SOBRE CADA LADO DEL BLOQUE. LAS HOJAS TIENEN UN LADO MAS CORTO CONECTADO A LOS TRAVESAÑOS.
