Abstract
DISPOSITIVO ANTI-AFROUXAMENTO. Um objeto da presente invenção é fornecer um dispositivo anti-afrouxamento que exibe seu efeito anti-afrouxamento por meio de um encaixe excêntrico entre uma saliência 12 de uma porca 10 e um recesso 22 em uma porca 20, em que a inclinação da porca 20 em relação à porca 10 quando eles foram apertados é minimizada. A superfície periférica externa da saliência 12 e a superfície periférica interna do recesso 22 são construídas de tal maneira que, com as porcas aparafusadas a um eixo rosqueado S e um encaixe excêntrico estabelecido entre a saliência 12 da porca 10 e o recesso 22 na porca 20, a porção de superfície periférica externa cônica 12a da saliência 12 interfere com a porção de superfície periférica interna cônica 22a do recesso 22 ao longo de parte da circunferência, enquanto uma lacuna é formada entre a porção de superfície periférica externa de extremidade distal 12b da saliência 12 e a porção de superfície periférica interna mais próxima de fundo 22b do recesso 22 ao longo de toda a circunferência.
