Abstract

Trattasi di un supporto perfezionato per cuscinetti evolventi, il quale comprende un cuscinetto evolvente, supportante un albero rotante e mantenuto posizionato da due settori semisferici, cooperanti con guarnizioni anulari di tenuta, applicati ad un corpo di supporto anulare, di maggiore diametro. I predetti due settori presentano una conformazione semisferica, con convessità rivolta verso il cuscinetto.
