Abstract

Tenditore per cinghie comprendente una struttura fissa (3), un braccio (4) rotante rispetto a un albero (7) della struttura fissa, una molla di torsione (6), una coppia di coni di smorzamento (8, 9), associati alla struttura fissa e al braccio, una molla di compressione (10) che agisce sui coni. Il raggio medio dei coni è minore della massima dimensione radiale della molla di torsione. Il valore "l" del braccio è correlato al raggio medio dei coni determinando uno smorzamento per attrito minore di quello fra albero e braccio rotante.
