Abstract

DISPOSITIVO ACTUADOR ELECTRICO ROBOTIZADO. CONSTA DE UN CARTER FIJO Y OTRO GIRATORIO, ACCIONADO POR UN MOTOR ELECTRICO QUE SE ALOJA DENTRO DE LOS MISMOS. UN TRANSFORMADOR DE COORDENADAS SE ALOJA EN UNA CAVIDAD REALIZADA EN EL ACTUADOR Y LA PARTE GIRATORIA DEL MISMO SE SUJETA EN EL CARTER GIRATORIO. COMO ELEMENTO DE DISIPACION DEL CALOR SE MONTA UN VENTILADOR EN EL ELEMENTO GIRATORIO DEL ACTUADOR Y SE DISPONE DE UN CIRCUITO CERRADO PARA EL PASO DEL AIRE ENTRE EL VENTILADOR Y UNA PLACA CONDUCTORA DEL CALOR QUE FORMA PARTE DEL CARTER FIJO. RODAMIENTOS DE BOLAS SOPORTAN UN EJE GIRATORIO QUE SE EXTIENDE A PARTIR DEL CARTER MOVIL, Y SE INCORPORA UN FRENO ELECTROMAGNETICO DE CONSTRUCCION LIGERA. ENTRE LA PARTE FIJA Y MOVIL SE INCLUYE UN ACOPLAMIENTO TIPO FUELLE PARA EL AISLAMIENTO ELASTICO DESTINADO A EVITAR LA DEFORMACION DE LOS ELEMENTOS PRODUCIDA POR LOS ESFUERZOS ENTRE LAS PARTES FIJA Y MOVIL.
