Abstract

EL ARBOL DE LEVAS SIRVE PARA LA REGULACION DE VALVULAS EN MAQUINAS DE COMBUSTION INTERNA. POSEE UN EJE (1) Y AL MENOS UNA LEVA (2) COLOCADA SOBRE EL EJE Y UNIDO CON EL DE FORMA FIJA, QUE DISPONE DE UNA ESCOTADURA (4) PARA LA COLOCACION DEL EJE. EL EJE DISPONE EN CADA ZONA, EN LA QUE ESTA PREVISTA LA LEVA, DIAMETROS AGRANDADOS EN COMPARACION CON OTRAS ZONAS DEL EJE EN FORMA DE SECCIONES. ESTAS ZONAS SON FABRICADAS POR MEDIO DE RODILLOS O BOLAS, CON LO QUE SE GENERA UNA ABOMBAMIENTO O UN NERVIO QUE DISCURRE ALREDEDOR DEL EJE A TRAVES DE UN PROCESO DE ELIMINACION DE MATERIAL EN DIRECCION PERIMETRICA. LA LEVA (2) ESTA CONFORMADA A TRAVES DE UN PROCESO DE FORJA. LA ESCOTADURA (4) EN LA LEVA (2) PARA LA COLOCACION DEL EJE (1) ESTA AL MENOS SOBRE UNA CARA Y AL MENOS SOBRE UNA PARTE EN SU LONGITUD AXIAL ABOCARDADA EN FORMA DE EMBUDO. LA MEDIDA DE LA ABERTURA DEL ABOCARDAMIENTO (6) DE TIPO DE EMBUDO CORRESPONDE APROXIMADAMENTE CON LA ALTURA RADIAL DEL ABOMBAMIENTO O DEL NERVIO (7).
