ABSTRACT:
A slaving and blocking device for transmitting a torque from a driving part to a driven part and for stopping the driven part at a torque engaging the driven part has a slaving element fixable on the driving part and having slaving claws offset from one another in a circumferential direction, a roller star wheel connectable to the driven part and having points of a star offset from one another in the circumferential direction, and a stationary clamping ring located concentrically with the slaving element and the roller star wheel. A contact face on the points of the star is configured so that the clamping rollers, which when the slaving element is driven are pressed by the slaving claws against contact faces of the points of the star, are thrust inwards. The slaving faces on the slaving claws are configured such that when the slaving element is driven, they load the clamping rollers with a pressure force such that a tangential force component of the pressure force is substantially greater than a radial force component of the pressure force.
