Abstract

ACCIONADOR LINEAL COMPACTO MOVIDO ELECTRICAMENTE QUE TIENE UN MOTOR ELECTRICO DISPUESTO EN UN ALOJAMIENTO. EL MOTOR ELECTRICO TIENE UN CONJUNTO DE ROTOR DE FORMA CILINDRICA ACOPLADO A UN EJE ROSCADO Y QUE LO RODEA. UNA PARTE DEL EJE ROSCADO SE INTRODUCE EN UN ORIFICIO AXIAL DE UN BRAZO EXTENSIBLE NO GIRATORIO. UNA TUERCA ACOPLADA A UN EXTREMO DEL BRAZO EXTENSIBLE NO GIRATORIO VA RECIBIDA A ROSCA EN EL EJE ROSCADO. LA ROTACION DEL EJE ROSCADO POR PARTE DEL MOTOR ELECTRICO DESPLAZA LINEALMENTE LA TUERCA Y EL BRAZO EXTENSIBLE NO GIRATORIO A LO LARGO DEL EJE ROSCADO. EN LA REALIZACION PREFERIDA, EL EJE ROSCADO TIENE UNA RANURA DE BOLA HELICOIDAL Y LA TUERCA ES UNA TUERCA DE BOLA COINCIDENTE.ELECTRICALLY MOVED COMPACT LINEAR ACTUATOR HAVING AN ELECTRIC MOTOR ARRANGED IN A HOUSING. THE ELECTRIC MOTOR HAS A CYLINDRICAL SHAPED ROTOR ASSEMBLY COUPLED TO A THREADED AXLE AND SURROUNDING IT. A PART OF THE THREADED SHAFT IS INTRODUCED IN AN AXIAL HOLE OF A NON-ROTATING EXTENSIBLE ARM. A NUT COUPLED TO AN END OF THE NON-ROTATING EXTENSIBLE ARM IS RECEIVED A THREAD ON THE THREADED SHAFT. ROTATION OF THE THREADED SHAFT BY THE ELECTRIC MOTOR MOVES THE NUT AND THE NON-ROTATING EXTENDABLE ARM ALONG THE THREADED SHAFT. IN THE PREFERRED EMBODIMENT, THE THREADED SHAFT HAS A HELICAL BALL SLOT AND THE NUT IS A MATCHING BALL NUT.
