FIELD: machine building. ^ SUBSTANCE: present invention pertains to a friction clutch for a distribution device with a correction ribbon. The friction clutch has first and second main elements as well as tension elements. The first and second main elements are held with possibility for executing relative rotational motion. The first main element has a cylindrical element, coaxially passing through a circular opening of the second main element. The second main element has coaxial tension elements for holding and pre-stretching the elastic ring, directed around the tension elements. The tension elements are geometrically arranged in such a way that, the ring can be seen from the central opening in form of secant line sections. These sections radially bend outwards, when the cylindrical element of the first main element is put into the central opening of the second element, so as to create friction force between the ring and the outer wall of the cylindrical element during their relative rotational motion. ^ EFFECT: creation of reliable friction force between surfaces. ^ 10 cl, 3 dwg |
