Abstract

"MéTODO PARA IMPOSIçãO DE UMA FORçA SUBSTANCIALMENTE CONSTANTE A UM OBJETO, ATUADOR DE FORçA SUBSTANCIALMENTE CONSTANTE E MECANISMO DE ATUADOR DE FORçA CONSTANTE". Trata-se de um atuador de força substancialmente constante que é aplicável em centralizadores, dispositivos de ancoragem e de tração para uso em poços e que é aplicável a dispositivos de içamento tais como macacos e dispositivos de suporte de carga. Um ou mais conjuntos de braços de articulação são passíveis de movimento angular mediante a força de um ou mais elementos de transmissão de força desde um ângulo mínimo com os elementos de transmissão de força num espaçamento máximo até um ângulo máximo com os elementos de transmissão de força num espaçamento mínimo para imposição de uma força substancialmente constante a um objeto ou a uma superfície, com a direção da força sendo substancialmente perpendicular à direção de movimento linear relativo dos elementos de transmissão de força. Com os braços de articulação nos seus ângulos mínimos, elementos de controle de movimento sobre pelo menos um dos elementos de transmissão de força reagem com superfícies de guia dos braços de articulação para obtenção de movimento angular da articulação e para desenvolvimento de uma força substancialmente constante durante o movimento angular da articulação.
