Abstract

1/1 resumo “galerias de óleo de pistão forjadas de formato complexo” trata-se de um pistão de aço com uma galeria de óleo e de um processo para formar um canal de galeria de óleo de pistão de aço, que corresponde ao formato complexo do vaso de combustão na coroa de pistão. o canal de galeria de óleo é, primeiramente, forjado para ficar com o formato básico que corresponde ao formato das paredes do vaso de combustão. as superfícies de torneamento por máquina no canal de galeria de óleo podem ser arrematadas por máquina conforme desejado. as superfícies na galeria de óleo que não podem ser usinadas com operações de torneamento convencionais, tais como entalhes e protuberâncias no canal, são deixadas na condição forjada original.
