First claim
Opening claim text (preview).
What is claimed is: 1. A sun gear for an integrated drive generator (IDG) comprising: a sun gear body including an outer diametric edge and an inner diametric wall, the outer diametric edge including 33 gear teeth, wherein the inner diametric wall comprises a plurality of inner splines, wherein the plurality of inner splines are 18 in number, wherein each of the plurality of inner splines comprise a major diameter, a minor diameter, and a pitch diameter. 2. The sun gear according to claim 1 , wherein the 33 gear teeth include a root diameter of between about 1.497-inch (3.802-cm) and about 1.510-inch (3.835-cm). 3. The sun gear according to claim 2 , wherein the 33 gear teeth include a root diameter of about 1.510-inch (3.835-cm). 4. The sun gear according to claim 1 , wherein the 33 gear teeth include a pitch diameter of about 1.650-inch (4.191-cm). 5. The sun gear according to claim 1 , wherein the 18 splines include the major diameter of between about 0.825-inch (2.095-cm) and about 0.839-inch (2.131-cm). 6. The sun gear according to claim 1 , wherein the 18 splines include the minor diameter of between about 0.708-inch (1.798-cm) and about 0.713-inch (1.811-cm). 7. The sun gear according to claim 1 , wherein the 18 splines include the pitch diameter of about 0.75-inch (1.905-cm). 8. The sun gear according to claim 1 , wherein the 33 gear teeth define an outer diameter of the sun gear body of between about 1.742-inch (4.425-cm) and about 1.745-inch (4.432-cm). 9. An integrated drive generator (IDG) comprising: a housing; and a differential gear system arranged within the housing, the differential gear system including a sun gear having a sun gear body including an outer diametric edge and an inner diametric wall, the outer diametric edge including 33 gear teeth, wherein the inner diametric wall comprises a plurality of inner splines, wherein the plurality of inner splines are 18 in number, wherein each of the plurality of inner splines comprise a major diameter, a minor diameter, and a pitch diameter. 10. The integrated drive generator according to claim 9 , wherein the 33 gear teeth include a root diameter of between about 1.497-inch (3.802-cm) and about 1.510-inch (3.835-cm). 11. The integrated drive generator according to claim 9 , wherein the inner diametric wall includes 18 splines. 12. The integrated drive generator according to claim 11 wherein the 18 splines include a major diameter of between about 0.825-inch (2.095-cm) and about 0.839-inch (2.131-cm). 13. The integrated drive generator according to claim 11 , wherein the 18 splines include a minor diameter of between about 0.708-inch (1.798-cm) and about 0.713-inch (1.811-cm). 14. The integrated drive generator according to claim 9 , wherein the 33 gear teeth define an outer diameter of the sun gear body of between about 1.742-inch (4.425-cm) and about 1.745-inch (4.432-cm). 15. The integrated drive generator according to claim 9 , wherein the 18 splines include the major diameter of between about 0.825-inch (2.095-cm) and about 0.839-inch (2.131-cm). 16. The integrated drive generator according to claim 9 , wherein the 18 splines include the minor diameter of between about 0.708-inch (1.798-cm) and about 0.713-inch (1.811-cm). 17.
