Abstract

PORTA FERRAMENTA ROTATIVO PARA RETER, DE MANEIRA SEPARáVEL, UMA FERRAMENTA ROTATIVA EM UM FURO CÈNICO DE UM EIXO Trata-se de um porta ferramenta rotativo (20) que inclui uma haste (58) que tem um flange (56), uma superfície externa cónica (64) e partes de contato frontal e traseira (60). A superfície externa cónica (64) corresponde ao furo cónico de um eixo e cantiléveres circulares flexíveis (70, 103) são proporcionados em uma ou ambas partes de contato tal que uma extremidade livre (76, 105) dos cantiléveres se expande radialmente devido à força centrífuga para manter contato com o furo cónico (53). A haste (58) pode ser formada a partir de um elemento interno (113) e uma camisa (115) disposta sobre ele, em que partes da camisa (115) formam os cantiléveres circulares. Os cantiléveres circulares (256) pode ser formados também por uma cavidade (260) criada na haste (253). Alternativamente, ao invés de cantiléveres circulares (256) a haste do porta ferramenta pode ter uma conicidade que seja otimizada para uma certa velocidade, em que a conicidade da haste (403) tem uma primeira conicidade em descanso e uma conicidade diferente a uma velocidade desejada.
