Abstract

"APARELHO INDICADOR DE CARGA DE PARAFUSO DE AMPLIFICAçãO VARIáVEL E MéTODO DE FABRICAçãO E UTILIZAçãO DO APARELHO". Um fixador indicando uma carga amplificada de forma variável inclui um fixador (100) preso de forma destacável a um indicador de carga através de um elemento base. O fixador (100) possui um apoio que é movido por uma alteração no comprimento sob uma carga aplicada. O indicador de carga inclui uma placa de mostrador (16), uma agulha (24) suportada de forma articulada pela placa (16), uma fenda de compensação (36), uma fenda de acionamento, um elemento em forma de U alongado (50) disposto na direção na qual a carga é aplicada quando o fixador (100) está em uso, e uma primeira marca de referência (40a). Um lado do U é fixado de forma rígida ao fixador. A extremidade fechada do U está perto de e é móvel pelo apoio. O outro lado do U se estende através da fenda de compensação (36) e fenda de acionamento (26). A agulha (24) é acoplada de forma operacional à extremidade externa do dito segundo lado. Uma manga com uma segunda marca de referência encaixa sobre a circunferência externa de ambos o indicador de carga e o elemento base.
