Planetary Gear

Aim :- Designing a planetary gear with motion analysis

Planetary gear is also knows as epicyclic gear train consists of sun gear , planet gear and ring gear.A Carrier is mounted to the planetary gear as shown.The sun gear is mounted at the center around which planetary gear are mounter which revolve around them The planetary gear are meshing internally with the ring gear which is an internal gear.

Complex mechanical assemblies present in design challanges that require dynamics system level analysis with the motion study analysis

The Designing inputs of the planetary gear

• Ring Gear
  • Module = 2.5 (You must use the metric system in design modeler)
  • Number of teeth = 46
• Sun Gear
  • Number of teeth = 14
• Input Speed of the Gear = 200 rpm.
• Number of planet gears = 4

Sl.No	Input	Output	Fixed
1	Sun Gear	Carrier	Ring Gear
2	Ring Gear	Carrier	Sun Gear
3	Sun Gear	Ring Gear	Carrier

There are various components used :-

1) Sun gear

2) Planetary Gear

3) Ring gear

4) carrier

Condition 1

Input :- Sun Gear , Output :- Carrier , Fixed :- Ring Gear.

Condition 2

Input :- Ring Gear , Output :- Carrier , Fixed :- Sun Gear.

Conditon 3

Input :- Sun Gear , Output :- Ring Gear , Fixed :- Carrier.
