Abstract

uma broca de perfuração inclui um corpo de broca que possui uma ou mais lâminas que se estendem a partir do mesmo e uma pluralidade de cortadores fixados a uma ou mais lâminas. um ou mais elementos rotativos são posicionados no corpo de broca, cada elemento rotativo tendo um eixo de rotação, proporcionando uma ou mais porções de rolamento cilíndricas que podem rodar em torno do eixo de rotação. cada elemento de rolamento está acoplado rotativamente ao corpo da broca dentro de um compartimento que define uma ou mais superfícies de rolamento internas, que incluem parcialmente as uma ou mais porções de rolamento cilíndricas, mas que deixa um comprimento total do elemento rotativo exposto.
