Electric generator oil pump driven gear

摘要

A driven gear (30) includes a radially outwardly extending flange (60). The radially outwardly extending flange (60) extends along an axial distance defined along a center axis of the flange (60). The flange (60) merges into a generally conical portion (64) which, in turn, extends radially inwardly to a hub (26). The hub (26) extends to a remote end (42). A first distance defined between the remote end (42) of the hub (26) and an end of the flange (60) faces the remote end (42). A second distance is defined between ends of the flange (60), with gear teeth (32;132) formed at an outer periphery. A ratio of the first distance to the second distance is between 2.541 and 2.824. An oil pump, a rotating portion for an electrical generator (24), and a generator (24) are also disclosed.
