Abstract

A belt-driven rotary drive having a belt closed upon itself which is connected, within a pressure fluid-tight housing over roller-shaped bodies with the formation of movable pressure chambers, to a rotatable shaft which is extended out of the housing and the movable pressure chambers can be acted on by pressure fluid. In order further to develop a belt-driven rotary drive of this type in such a manner that the sealing action and the friction caused thereby can always be adjusted in simple manner from the outside, it is proposed that the closed belt (1) be adapted to be pressed on itself over a part of its length, with the formation of two pressure chambers which are pressure fluid-tight from each other, by a static pressing member which acts in the direction towards one of the roller-shaped bodies and that the pressing member be functionally connected for the adjustment of the pressing force with an adjusting device which is adjustable from the outside.
