Abstract

Patente de Invenção: <B>''MéTODO E APARELHO PARA PRODUZIR UMA RODA DENTADA''<D>. São descritos um método e um aparelho para produzir uma roda dentada a partir de um modelo de metal em pó (1) prensado e sinterizado com uma sobremedida na área do conjunto de dentes, cujo modelo de metal em pó é compactado, sob uma deformação plástica, nas vizinhanças da sobremedida por prensagem contra um contraconjunto de dentes (8) de pelo menos uma ferramenta de prensagem rotativa (3) pela sobremedida, cujo contraconjunto de dentes se acopla no conjunto de dentes (9) do modelo de metal em pó (1). Para criar condições construtivas vantajosas, propõe-se que o contraconjunto de dentes (8), projetado como o conjunto de dentes interno da ferramenta de prensagem anular (3), encerrando o modelo de metal pó (1), seja prensado no conjunto de dentes (9) do modelo de metal em pó (1), por meio de um rolamento de rolo de pressão sobre a periferia externa (10) da ferramenta de prensagem (3).
