Abstract

TRAVA MECáNICA PARA MANCAL COM FILME DE óLEO PARA LAMINADOR. A presente invenção refere-se a um mancal com filme de óleo que é assentado no pescoço afunilado de um cilindro de laminador por meio de uma unidade de pistão/cilindro atuada hidraulicamente. A unidade de pistão/cilindro é axialmente confinada por braços de travamento rosqueados externamente assentados em uma ranhura no pescoço do cilindro. Uma porca de travamento é rosqueada sobre os braços de travamento.
