Transmission Gears AISI 4140 External Spur Gear with Internal Ring Gear
1) Descripton of Internal Ring Gear
An internal gear can also be called a ring gear. Internal gears are used in planetary gear box applications,
but can also be applied in other situations. Advantages of the use of a planetary gear train are low vibration,
high speed reduction ratio, and the low cost for the entire train layout. Since the centers of the mating wheels
can be closer than those of external gears, internal spur gears are preferred in applications where space is a constraint.
2) Applications of Internal Ring Gear
The common uses for planetary gear transmissions are robotic arms, hybrid vehicle power transmissions and turbine generators.
