Abstract

1/1 resumo “galerias de óleo de pistão de formato complexo com coroas de pistão feitas por processos de metal fundido ou de metal em pó” 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. a coroa de pistão é feita por um processo de formação por metal fundido ou pó metálico. o canal de galeria de óleo é formado 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 somente formada original.
