Universal coupling for shafts - has three double-ended, forked transmission components allowing shafts to be offset

摘要

The coupling comprises a driving flange (1) with three equi-spaced spigots (2,12,22) on it's face and a driven flange (1') with similar spigots (2',12',22'). The transmission components (5,15,25) are housed together between the two flanges. The transmission components each consist of a double-ended forked lever. All three are assembled together using the central spigot (7) of the first lever (5) with a retaining circlip. Each lever engages with one spigot of each disc via square guides (3,3'; 13,13'; 23,23').
