Abstract

"VEDAçãO PARA UM MANCAL DE ROLAMENTO". A invenção refere-se a uma polia de tensão (1) para um acionamento de mecanismo de tração que abrange um disco de rotação (2) apoiado podendo girar, bem como, um distanciador (4a). Entre o disco de rotação (2) e o distanciador (4a) está prevista uma tampa de vedação (13a) que possibilita uma disposição segura contra perda de todos componentes da polia de tensão.
