Abstract

"JUNTA ROSQUEADA E UMA PORçãO MACHO". A presente invenção se refere a uma junta rosqueada com porção macho e porção fêmea para perfuração à percussão. A junta rosqueada inclui pelo menos uma rosca externa geralmente cilíndrica (14) e uma rosca interna geralmente cilíndrica (15). A dita rosca externa (14) é fornecida sobre um batoque (12), idealizado para se constituir em uma parte integral de um primeiro componente sequenciado de perfuração (10A, 10B). As roscas compreendem extremidades de roscas fornecidas em conexão com perfis inteiros de roscas associadas. As roscas (14, 15) compreendem áreas de extremidade onde cada rosca em uma seção longitudinal apresenta seu menor raio (R). A rosca externa geralmente cilíndrica (14) apresenta uma primeira extensão axial (L1) e a rosca interna geralmente cilíndrica (15) apresenta uma segunda extensão axial (L2), em que a primeira extensão axial (L1) é mais curta que a segunda extensão axial (L2), de modo que ambas áreas de extremidade (23, 24) da rosca interna cilíndrica (15) não entrem em contato com a rosca interna cilíndrica (14)."THREADED JOINT AND A MALE PORTION". The present invention relates to a threaded joint with male portion and female portion for percussion drilling. The threaded joint includes at least one generally cylindrical outer thread (14) and one generally cylindrical inner thread (15). Said external thread (14) is provided on a toggle (12), idealized to constitute an integral part of a first sequential drilling component (10A, 10B). The threads comprise thread ends supplied in connection with entire profiles of associated threads. The threads (14, 15) comprise end areas where each thread in a longitudinal section has its smallest radius (R). The generally cylindrical external thread (14) has a first axial extension (L1) and the generally cylindrical internal thread (15) has a second axial extension (L2), where the first axial extension (L1) is shorter than the second extension axial (L2), so that both end areas (23, 24) of the cylindrical internal thread (15) do not come into contact with the cylindrical internal thread (14).
