Abstract

EN UN EJE DE CIGUEÑAL CON ESPIGAS HUECAS SE HAN COLOCADO EN LAS APERTURAS DE SALIDA DE LAS ESPIGAS PRINCIPALES Y DE LAS ESPIGAS DE CARRERA DE LAS MORDAZAS DEL CIGUEÑAL EXTENSORES DISTRIBUIDOS SOBRE SU SECCION QUE PRODUCEN UNA PRETENSION EN EL MATERIAL DE LAS MORDAZAS DEL CIGUEÑAL PARA ALCANZAR UNA MAYOR SOLIDEZ AL CURVADO Y LA TORSION Y EVITAR QUE SE FORMEN GRIETAS QUE PONGAN EN PELIGRO LA SECCION DEL EJE. TENSANDO MAS LAS ESPIGAS EN SU LONGITUD SE PUEDE ELEVAR LA FRECUENCIA PROPIA DEL EJE A CAMPOS NO CRITICOS.
