Abstract

Elemento di tensionamento di cinghia avente un braccio di tensionamento collegato oscillabilmente ad un elemento stazionario attorno ad un albero oscillante e un elemento di impegno di cinghia per impegnare una cinghia e supportato girevolmente in corrispondenza del braccio di tensionamento. Un primo elemento di sollecitazione sollecita il braccio di tensionamento o tensionatore girevolmente attorno al braccio oscillante in modo tale che l'elemento di impegno della cinghia tensiona la cinghia. Un elemento di smorzamento è disposto fra l'elemento stazionario e il braccio tensionatore in modo tale che attrito viene prodotto fra l'elemento stazionario e l'elemento di smorzamento al fine di smorzare il movimento oscillatorio del braccio tensionatore quando il braccio tensionatore o di tensionamento oscillata. Un secondo elemento di sollecitazione sollecita; l'elemento di smorzamento verso l'elemento stazionario o viceversa al fine di produrre l'attrito.
