Abstract

PERFECCIONAMIENTOS EN UN ACCIONADOR ELECTRICO.SE COMPONE DE UN DISPOSITIVO Y UN CIRCUITO ELECTRICO QUE MARCA AL DISPOSITIVO LA PRESION A EJERCER POR EL ACCIONADOR EN CADA MOMENTO. LA PRESION EN LOS EXTREMOS DEL ACCIONADOR (4) SE EJERCE POR DIFERENCIA DE FUERZAS ENTRE EL RESORTE MOTOR (1) Y EL RESORTE DE CONTROL (10), SIENDO VARIABLE MEDIANTE LA ROTACION DEL TORNILLO (11) DENTRO DE LA ROSCA (9) QUE EJERCE PRESION SOBRE EL RESORTE DE CONTROL, HASTA UN MINIMO, REGULADO EN FUNCION DE LA FRENADA MAXIMA, POR EL CIRCUITO ELECTRICO MEDIANTE EL MICROCONMUTADOR (48). EL CIRCUITO ELECTRICO DIRIGE EL SENTIDO DE GIRO DEL MOTOR (14) Y LA LIBERACION O NO DEL ENGRANAJE (13, 12) DE TRANSMISION, MEDIANTE EL TRINQUETE (45) MOVIDO POR EL SOLENOIDE (46) EN FUNCION DE QUE HAYA QUE FRENAR O NO Y DE QUE PRESION DE FRENADA ES LA ADECUADA EN CADA MOMENTO.
