<p>A coupling system for connecting a sun gear (56) to a shaft (28) within a planetary gear train, includes a sun gear coupling (40) connecting the sun gear (56) to the shaft (28). The sun gear coupling (40) has at least one undulant flexible section (44) joined to an inflexible spindle (42) for accommodating misalignment between the sun gear (56) and the shaft (28). The flexible section (44) comprises a cylindrical ring (68) having a diameter greater than the diameter of the spindle (42), and joined to the spindle (42) by two longitudinally spaced apart diaphragms (70,72). The juncture between the diaphragms (70,72), the ring (68), and the spindle (42) is curved in cross section on an outer side to improve flexibility and minimize stress concentrations, and the inner sides (112,114) of the diaphragms (70,72) are straight edges which result in a non-symmetric contour of the diaphragm walls.</p> |
