Abstract:
1. A link module for connecting two coupling hubs to form a coupling that extends longitudinally around a central axis, where each coupling hub comprises a body with a cylindrical base and a plurality of projections spaced circumferentially around the base, the link module comprising: a hollow, semi-cylindrical linking element, the linking element formed by a plurality of circumferentially spaced linking bars extending parallel to the central axis, wherein opposing ends of each linking bar are connected to adjacent linking bars by bent connecting portions, and wherein each of the linking bars is adapted to be received between aligned pairs of projections on the coupling hubs, in a mounted state of the link module, grease between each of the plurality of linking bars for lubricating a connection between the plurality of linking bars and the two coupling hubs, and an envelope surrounding the linking bars and the grease, wherein the envelope comprises a frangible inner wall that must be broken by pressing the linking element onto the projections to connect the linking bars to the coupling hubs, wherein the envelope, in a first state not mounted on the two coupling hubs, contains the grease within the envelope.
