Abstract

sistema e método para ajustar de rolo de cone com perfil híbrido em bits. uma broca chata de perfuração de terra (11) projetada para um desempenho específico, dentro de uma tolerância do produto final, utilizando componentes construídos para uma perda da tolerância de fabricação. as brocas podem ser montadas através da seleção de uma perna (17) a partir de uma pluralidade de pernas pré-fabricadas: selecinando um corpo das brocas (13) a partir de uma pluralidade de corpos de bricas pré-fabricados, os corpos de brocas, tendo uma renhura (123) para receber a perna; colocação da perna no interior da ranhura; e fixação da perna no interior da ranhura dentro da tolerância do produto final ao colocar um ou mais placas metálicas de calçamento (200) entre a perna e a ranhura. as placas metálicas de calçamento podem ser utilizados para ajustar uma posição axial, de uma posição radial e/ou uma posição periférica de perna em relação à ranhura. a perna e o corpo da broca podem ser escolhidas, ou produzidas, para garantir que a broca não satisfaça a especificação, dada a tolerância de fabricação, sem as placas metálicas de calçamento.
