Abstract

DISPOSITIVO EN EL QUE UNA TUERCA LOCA SE DESPLAZA SOBRE UNA VARILLA ROSCADA (10). UNO DE ESTOS ELEMENTOS ES ARRASTRADO EN ROTACION POR EL MOTOR A CONTROLAR Y LA TUERCA LOCA ACCIONA UN INTERRUPTOR (21) CUANDO LLEGA AL FINAL DE SU RECORRIDO DESPUES DE UN NUMERO DETERMINADO DE VUELTAS DEL MOTOR. LA TUERCA LOCA (8) ES SOLIDARIA EN ROTACION DE UNA SEGUNDA TUERCA (12) DESTINADA A COOPERAR CON UNA SEGUNDA PARTE ROSCADA (13) SITUADA EN EL EXTREMO DE LA PRIMERA PARTE ROSCADA (10), DE DIAMETRO SUPERIOR AL DIAMETRO DE LA PRIMERA PARTE ROSCADA, Y CUYO PASO DE ROSCA ES SENSIBLEMENTE MAYOR QUE EL PASO DE ROSCA DE LA PRIMERA PARTE ROSCADA (10), DE TAL MANERA QUE CUANDO LA SEGUNDA TUERCA (12) SE ENGRANA CON LA SEGUNDA PARTE ROSCADA (13), SE DESPLAZA MAS RAPIDAMENTE QUE LA PRIMERA TUERCA Y VA A ACCIONAR RAPIDAMENTE EL INTERRUPTOR. ESTE PERFECCIONAMIENTO PERMITE AUMENTAR LA PRECISION DE PARADA DEL MOTOR INDEPENDIENTEMENTE DEL TAMAÑO DEL PASO DE LA PRIMERA PARTE ROSCADA, ES DECIR, INDEPENDIENTEMENTE DE LA LONGITUD DE ESTA PARTE ROSCADA, ES DECIR DEL VOLUMEN DEL DISPOSITIVO.
