1) Material of Internal Gear
40Cr alloy steel of AISI 4140 (42CrMo) Steel is widely used for internal gear
2) Applications of Internal Gear
Planetary drive system usually need internal gear ring.
Internal gear can also be used for other power transmission system.
3) Heat treatment of Internal Gear
Nitriding Heat treatment is suggested for internal gears, because the tooth profile will with large
deformation after the carburizing heat treament.
