Abstract

UN SISTEMA PARA DETERMINAR EL DESPLAZAMIENTO AXIAL DE UNA BIELA (1) QUE FORMA PARTE DE UN DISPOSITIVO QUE CONSTA DE UN MIEMBRO (2) EN EL QUE SE FORMAN AL MENOS DOS CUERPOS (4, 5) QUE CONTIENEN FLUIDO DE ALTA PRESION Y CADA UNO VIENE DEFINIDO POR UNA PORCION DE SUPERFICIE RESPECTIVA DE LA BIELA (1). EL SISTEMA CONSISTE EN LA FORMACION DE UN ACOPLAMIENTO DESLIZANTE ENTRE LA PORCION DE LA BIELA (6) QUE SEPARA LOS DOS CUERPOS (4, 5) Y EL ASIENTO (3) EN QUE SE DESLIZA LA BIELA (1); EN FORMAR, SOBRE LA PORCION DE LA BIELA ANTES MENCIONADA (6), UN PAR DE MUESCAS ANULARES (7, 8) QUE DEFINEN UNA PORCION DE SUPERFICIE ANULAR (9); EN FORMAR AL MENOS UN ALOJAMIENTO (10) SOBRE EL MIEMBRO ANTES MENCIONADO (2); Y EN FIJAR DENTRO DEL ALOJAMIENTO (10) UN TRANSDUCTOR DE PROXIMIDAD (10) PARA DETERMINAR EL DESPLAZAMIENTO DE LA PORCION DE SUPERFICIE ANULAR (9) DE FORMA PARALELA A LA BIELA (1).
