ABSTRACT:
An overload clutch for a winch or the like offering a rolling or compression resistance between the rope drum and the rope drum power axle.
The rope drum is connected at one flange to the power axle via an ancillary compensation member in the form of an inwardly running drum body or shaft. Placed between the rope drum and the ancillary compensation member are a plurality of rollers, made of an elastic material, and assembled together in the form of a roller cage. The rollers, which are oval in cross-section, are bonded to roller axles and are separated from each other by spacer rods. The interaction of the rollers with the rope drum and the ancillary compensation member is responsible for a non-positive driving connection between the rope drum and the power axle.
