Abstract

UN ARBOL COMPUESTO, EN ESPECIAL UN ARBOL DE LEVAS, UN EJE DE TRANSMISION O UN CIGUEÑAL CON AL MENOS UN CUERPO TUBULAR Y CON VARIOS ELEMENTOS, TALES COMO LEVAS, ENGRANAJES, CASQUILLOS DE APOYO O GUALDERAS, MONTADOS EN EL POR ENSANCHAMIENTO DE TRAMOS LONGITUDINALES DEL ARBOL, POSEE UN CUERPO TUBULAR, QUE, CON UN GRUESO DE PARED APROXIMADAMENTE CONSTANTE, POSEE UN DIAMETRO REDUCIDO EN LA ZONA ENTRE DOS ELEMENTOS. CON ELLO ES POSIBLE OBTENER CON UNA PRESION INTERIOR APROPIADA EN LA TOTALIDAD DEL CUERPO TUBULAR UNA DEFORMACION PLASTICA DE LOS TRAMOS DE MAYOR DIAMETRO CON RELACION A LOS ELEMENTOS DE ACCIONAMIENTO A FIJAR, MIENTRAS QUE LA DEFORMACION DE LOS TRAMOS DE TUBO DE MENOR DIAMETRO SITUADOS ENTRE LOS ELEMENTOS DE ACCIONAMIENTO PERMANECE EN EL MARGEN ELASTICO. EN UNA CONFIGURACION VENTAJOSDA SE PREVEN ENTRE CADA DOS ELEMENTOS CASQUILLOS CON UN DIAMETRO MAYOR QUE EL DEL CUERPO TUBULAR, CUYOS EXTREMOS SE FIJAN ENTRE EL CUERPO TUBULAR Y LOS ELEMENTOS.
