Abstract
L'invenzione concerne un azionamento rotante mosso da una cinghia con una cinghia chiusa a forma di anello, la quale è collegata in un corpo a tenuta di fluido sotto pressione, con formazione di camere sotto pressione mobili attorno a corpi e forma di rulli, con un albero girevole, portato dal corpo verso l'esterno e le camere sotto pressione mobili sono alimentabili da fluido sotto pressione. Per perfezionare un azionamento rotante mosso da una cinghia di questo genere in modo che l'effetto di tenuta e l'attrito da esso provocato siano sempre successivamente regolabili dall'esterno in modo semplice, viene proposto che la cinghia chiusa (1), con formazione di due camere sotto pressione a tenuta di fluido sotto pressione l'una rispetto l'altra, sia premibile l'una sull'altra su una parte della sua lunghezza da un elemento pressore (5), statico, agente in direzione di uno dei corpi (4, 4', 4") a forma di rulli, e che l'elemento pressore (5) si trova in collegamento efficace con un dispositivo di regolazione (6), regolabile dall'esterno, per la regolazione successiva della forza di pressione.
