Abstract

tensionador com mola expansora para amortecimento assimétrico de atrito radial. a presente invenção refere-se a um tensionador que pode fazer parte de um sistema de potência onde o tensionador provê uma tensão para um elemento de transmissão de potência sem fim tal como uma coreeia, uma corrente, ou outro loop contínuo. o tensionador tem um braço que é rotativo ao redor de um primeiro eixo geométrico e inclui uma árvore de braço que tem uma fenda através da mesma, uma bucha que tem uma protuberância e sendo posicionada adjacente à árvore de braço com a protuberância recebida dentro da fenda da árvore de braço, e uma mola acoplada no braço que força o braço para girar ao redor do primeiro eixo geométrico em acoplamentgo de tensionamento com um elemento de transmissão de potência. a mola está posiiconada onde esta pode expandir radialmente em contato com a protuberância da bucvha conforme o braço é girado em uma direção oposta à direção de acoplamento de tensionamento de modo que a bucha é forçada radialmente para fora em relação à árvore de braço para prover o amortecimento por atrito.
