Abstract

UN TORNILLO DE FRICCION REDUCIDA (1). EL TORNILLO (1) REQUIERE UNA TORSION MENOR QUE UN TORNILLO CONVENCIONAL PARA DIRIGIRLO EN UNA PIEZA DE TRABAJO. EL EJE (2) DEL TORNILLO (1) POSEE UN ESTRIADO CON GROSOR REDUCIDO (5) QUE PRODUCE MENOR FRICCION DE DESLIZAMIENTO QUE UN TORNILLO CONVENCIONAL CON UN ESTRIADO DE LA MISMA PROFUNDIDAD Y ALTURA. ADEMAS, LA DEBILIDAD DE SUJECION DEL TORNILLO DE FRICCION REDUCIDA (1) ES SUSTANCIALMENTE QUE AL DE UN TORNILLO CONVENCIONAL CON UN ESTRIADO DE LA MISMA PROFUNDIDAD Y ALTURA. OTRA INCORPORACION CONTIENE UN EJE (2'') CON UN DIAMETRO REDUCIDO, PARA REDUCIR MAS AUN LA FRICCION DESLIZANTE. OTRA INCORPORACION CONTIENE UN ESTRIADO DE GROSOR REDUCIDO SEGMENTADO (41) QUE RESISTE A LA EXTRACCION Y EL AFLOJAMIENTO CUANDO LA PIEZA DE TRABAJO ES SOMETIDA A VIBRACIONES, RETORCIMIENTOS DOBLAMIENTOS, ETC. PARA EVITAR EL AFLOJAMIENTO DEL TORNILLO DE FRICCION REDUCIDA, LA BASE DE LA CABEZA DEL TORNILLO PUEDE CONTENER PROTUSIONES (7) PARA INCREMENTAR EL CONTACTO FRICCIONALDE LA CABEZA (3) CON LA PIEZA DE TRABAJO.
