ABSTRACT:
A rotary clutch (1) for the drive of cleaning spirals (6) for the cleaning of pipelines has a set of clutch jaws (2), which can move radially with respect to the axis (A--A) of the clutch, each of these jaws having an inner friction surface for carrying along the cleaning spiral (6) and at least one first outer control surface (8), extending at an angle to the clutch axis (A--A). A drivable control sleeve (4 or 5) with at least one second inner control surface (9) can execute relative motion toward this control surface (8), the inner control surface having an inclination comparable to that of the outer control surfaces (8) of the clutch jaw (2). To reduce the actuating forces and to increase the drive torque, the clutch jaws (2) and the control sleeve (4 or 5), at least one of which is provided, are provided with positively engaging carrier elements (10, 11).
