Abstract

a presente invenção se refere a uma disposição de mancal (1) para um cabeçote de perfuração por líquido de lavagem de um equipamento de perfuração profunda com vários anéis de mancal radialmente exteriores e radialmente interiores (6, 7), na qual os anéis de mancal radialmente exteriores (6) estão dispostos coaxialmente sobre os anéis de mancal radialmente interiores (7), na qual radialmente entre os anéis de mancal (6) estão dispostas esferas (8), as quais rolam em estrias de rolamento (6a, 7a) dos anéis de mancal (6, 7), e na qual as estrias de rolamento (6a, 7a) axialmente nos dois lados de ressaltos (6b, 7b) estão delimitadas com superfícies de ressalto (6c, 7c) situadas opostas uma à outra, que passam paralelas a um eixo longitudinal do mancal (11). a fim de executar uma disposição de mancal (1) desse tipo à qual se conecta o, pelo menos um, mancal plano na direção axial de acordo com o estado da técnica curta na extensão axial e a fim de simplificar a construção, o diâmetro interno (di) das superfícies de ressalto (6c, 7c) dos anéis de mancal radialmente exteriores (6) e o diâmetro externo (da) das superfícies de ressalto (7c) dos anéis de mancal radialmente interiores (7) é dimensionado de tal modo que essas superfícies de ressalto (6c, 7c) realizam a função de mancais planos radiais com uma folga radial (s).
