Abstract
A method of constructing an integral coupling system containing a sun gear is disclosed. An integral sun gear is provided that has a sun gear component and a connection shaft. A first straight flat inner edge is machined on a first diaphragm to use as a datum point, and then the straight flat edge is fixtured. A tapered outer edge is machined on the first diaphragm, and the first diaphragm is welded to the integral sun gear. The flat inner edge is generally perpendicular to a central axis of the connection shaft.
