The planetary mechanism based on normal connection of spur gear or helical gear installed in planetary shape.
This type of connection between gears provide high reduction ration in small size of whole gearbox.
** Most used in automatic gear transmission application
The main components of Planetary gearbox
Sun Gear: the gear in the center of mechanism.
Carrier: the part that holds the planet gears.
Planet Gear: the gears which rotate around the sun gear.
Internal Ring Gear: the internal gear that contains all parts of mechanism.
This Model Calculations depends on The Sun Gear is Input and Carrier is Output
