Abstract

MéTODO E APARELHO PARA ADENSAR ENGRENAGENS DE METAL EM Pó. A invenção apresenta um método e um aparelho para adensar os dentes de uma engrenagem de uma pré-forma de metal em pá. A matriz inclui uma abertura para receber o corpo de uma engrenagem e uma pluralidade de ranhuras para receber os dentes da engrenagem. As ranhuras apresentam um comprimento e uma largura variável ao longo do comprimento. As ranhuras se estreitam tangencialmente com relação à abertura. A engrenagem da pré-forma de metal em pó é pressionada através da matriz e os dentes são plasticamente e elasticamente deformados em uma porção relativamente estreita da ranhura. Depois de passarem através da porção estreita da ranhura e serem comprimidos, os dentes podem ser recuperados pelo menos parcialmente. As ranhuras afinadas pela matriz podem ser helicoidais para formarem uma ranhura helicoidal.
