<p>A number of embodiments of flexible coupling for transmitting torque from one rotatable member to another, and in such a way as to compensate automatically for any small misalignments between the driving and driven ends of the coupling. In the embodiment of Fig. 1 and 2, the flexible coupling (10) comprises a hollow cylindrical body (11) having an annular wall, and a helical spring configuration (14) formed in the annular walls with the turns thereof extending radially outwardly from the hollow interior (13) of the cylindrical body to the outer periphery of the cylindrical body. The helical spring configuration (14) comprises at least two spring formations extending circumferentially and adjacent to each other around the axis (15) of the cylindrical body (11), each formation extending in a continuous spiral from a start at one end portion of the cylindrical body to a finish at the opposite end portion.</p> |
