Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA AMORTIGUAR LAS VIBRACIONES DE MAQUINAS CORTADORAS DE TALLA PARCIAL (1), QUE COMPRENDE UN BRAZO DE PROLONGACION (3), QUE GIRA ALREDEDOR DE DOS EJES (5, 9) CON HERRAMIENTAS CORTANTES (7) MONTADAS DE FORMA ROTATIVA SOBRE LOS MISMOS. DICHO DISPOSITIVO TIENE UN MECANISMO HIDRAULICO (6), PARA ACCIONAR LA REGULACION, ALIMENTADO CON FLUIDO A TRAVES DE UN DISPOSITIVO DE VALVULA. SE DISPONEN UNOS SENSORES (13 O 14) A FIN DE DETECTAR LAS VIBRACIONES, ACELERACIONES, CARGA Y/O POSICION DEL BRAZO CORTANTE (3), Y QUE DISPARA LA CORRESPONDIENTE COMPENSACION DEL MECANISMO DE ACCIONAMIENTO REGULADOR FORMADO POR LAS UNIDADES (6) DE PISTON DE CILINDRO HIDRAULICO, POR MEDIO DE UN DISPOSITIVO DE CONTROL (16). DE ESTE MODO, SE MANTIENE BASICAMENTE CONSTANTE LA POSICION DEL BRAZO DE PROLONGACION (3), ALREDEDOR DEL EJE DE ROTACION VERTICAL (9), CUANDO GIRA EL MECANISMO OSCILANTE.
