<p>The cam has a hub (23) with a main section (23B) forming a central bore (23A) for mounting on a drive shaft, and a collar (23D) extending radially outwards from the hub's outer surface (23C). It also has two flanges (24, 25), each forming a roller track, with central holes (24A, 25A) for mounting on the outer radial surface of the main section on either side of the collar without projecting beyond the main section's sides (23B1, 23B2) in a direction parallel to the axis of the bore. The flanges are joined together by fixings (26) passing through holes (23E, 24E, 25E)) in the collar and flanges.</p> |
