Abstract

"DISCO DENTADO PARA MOTOSSERRA". A fundição em lote de discos dentados para motosserras, conforme particularmente aplicado a discos dentados maiores, experimenta uma taxa de refugo alta indesejada resultante da porosidade e da lascagem. A solução é garantir um fluxo de aço fundido por toda a solidificação do aço fundido no molde de disco dentado, enquanto se retêm entradas ou canais de alimentação de aço fundido de um tamanho que permita uma ruptura das hastes de entrada. Isso melhora a taxa de resfriamento do aço fundido no molde de disco dentado, o que mostrou ser benéfico. O objetivo da taxa de refugo reduzida é logrado, assim, pela manutenção de uma relação de massa para área superficial dos discos dentados sendo fundidos para não mais do que em torno de 4 gramas de material para cada para cada polegada quadrada (~ 6,45 cm ) de área superficial e, alternativamente, prover orifícios passantes através dos discos dentados, os quais adicionalmente ajudam na remoção de lasca de madeira. Este projeto também reduz a quantidade de material, o que reduz o custo e o peso do produto.
