Abstract

LA INVENCION SE REFIERE A UN TORNILLO QUE COMPRENDE UN VASTAGO QUE TIENE UNAS ROSCAS EXTERNAS Y UNA PARTE ENGRANABLE INTEGRAMENTE FORMADA EN UN EXTREMO DEL VASTAGO. LA PARTE ENGRANABLE TIENE UNA SUPERFICIE EXTERIOR FRUSTOEMISFERICA QUE COMPRENDE UNA PLURALIDAD DE CORTES CIRCUNFERENCIALMENTE SEPARADOS EN FORMA DE DIENTES. CADA UNO DE LOS DIENTES COMPRENDE UN DECLIVE QUE SE EXTIENDE HACIA EL EXTERIOR DESDE LA BASE HASTA LA PARTE SUPERIOR DEL MISMO, ESTANDO EL DECLIVE INCLINADO EN UNA DIRECCION QUE ES OPUESTA A LA DIRECCION DEL GIRO DE APRIETE DEL TORNILLO EN LA PIEZA. EN LA EXTREMIDAD EXTERIOR DE LA PARTE ENGRANABLE SE ENCUENTRA UNA CAVIDAD. LA CAVIDAD COOPERA CON LA SUPERFICIE EXTERIOR FRUSTOEMISFERICA PARA FORMAR ENTRE AMBAS UNA CUÑA ANULAR. LA PARTE ENGRANABLE PUEDE FABRICARSE FACILMENTE MEDIANTE UN PROCESO DE FORJA.
