Abstract

PISTON PARA MOTOR DE COMBUSTION INTERNA. SE DESCRIBEN PISTONES QUE TIENEN PERFILES POLARES O PERFILES AXIALES O PERFILES POLARES Y AXIALES, MECANIZADOS CON CURVATURAS ASIMETRICAS ALREDEDOR DEL PLANO QUE INCLUYE EL EJE GEOMETRICO DEL PISTON Y ELEJE MENOR AL MENOS SOBRE UNA PARTE DE LA LONGITUD DE LA FALDILLA. MECANIZANDO LOS PISTONES CON PERFILES ASIMETRICOS, LAS AREAS DE APOYO, POR EJEMPLO, DE LAS CARAS DE EMPUJE Y CONTRAEMPUJE DE LA FALDILLA DEL PISTON SE PUEDEN OPTIMIZAR CON MAYOR PRECISION. SE HA DEMOSTRADO QUE, DE ESTE MODO, SE CONSIGUEN EFECTOS BENEFICIOSOS EN LO QUE SE REFIERE AL RUIDO DEL PISTON,ROZAMIENTO Y DESGASTE, POR EJEMPLO, EN ALGUNAS APLICACIONES.
