The ring gear according to claim 2 , wherein the 129 gear teeth include a root diameter of about 6.315-inch (16.04-cm). 4 . The ring gear according to claim 1 , wherein the 129 gear teeth include a pitch diameter of about 6.45-inch (16.38-cm). 5 . The ring gear according to claim 1 , wherein the inner diametric wall includes 63 gear teeth. 6 . The ring gear according to claim 5 , wherein the 63 gear teeth include a root diameter of between about 3.280-inch (8.33-cm) and about 3.293-inch (8.364-cm). 7 . The ring gear according to claim 5 , wherein the 63 gear teeth include a pitch diameter of about 3.150-inch (8.001-cm). 8 . The ring gear according to claim 1 , wherein the 129 gear teeth define an outer diameter of the ring gear body of between about 6.550-inch (16.637-cm) and about 6.555-inch (16.649-cm). 9 . The ring gear according to claim 8 , wherein the 129 gear teeth define an outer diameter of the ring gear body of about 6.550-inch (16.637-cm). 10 . An integrated drive generator (IDG) comprising: a housing; and a differential gear system arranged within the housing, the differential gear system including a ring gear having a ring gear body including an outer diametric edge and an inner diametric wall, the outer diametric edge including 129 gear teeth. 11 . The integrated drive generator according to claim 10 , wherein the 129 gear teeth include a root diameter of between about 6.315-inch (16.04-cm) and about 6.328-inch (16.07-cm). 12 . The integrated drive generator according to claim 10 , wherein the 129 gear teeth include a pitch diameter of about 6.45-inch (16.38-cm). 13 . The integrated drive member according to claim 10 , wherein the inner diametric wall includes 63 gear teeth. 14 .
