Abstract
"CONJUNTO DE MANCAL, UNIDADE DE MANCAL EFERRAMENTA OU APARELHO". é exposto um mancalaperfeiçoado e particularmente um conjunto de mancalaperfeiçoado (15, 15A), por exemplo, uma conjunto de mancalaxial, que pode ser usada em aplicações de furo de poço, tal comoaplicações de perfuração de furo de poço. Montagens de mancalaxial para uso em aplicações de furo de poço tem os requisitosconflitantes de uma conjunto de eixo grossa e capacidade demancal de carga axial alta em uma seção transversal pequena. Ainvenção, portanto, provê: uma conjunto de mancal (15, 15A)tendo pelo menos dois elementos de mancal (400, 400A)espaçados por um primeiro corpo (500, 500A), o primeiro corpo(500, 500A) tendo meio para flexionar. Assim, quando uma carga éaplicada à conjunto de mancal (15, 15A), o primeiro corpo (500,50OA) é causado flexionar. Em uma concretização, o meio deflexão inclui pelo menos um sulco circunferencial ou recorte (510,510A) formado no primeiro corpo (500. 500A).
