Planetary Gear
Aim:
To design and assemble Planetary gear arrangement and do motion study on it using solidworks.
Solution:
Planetary Gear (or) Epicyloic gear train:
An epicyclic gear train (also known as planetary gear) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates to carry one gear, called the planet gear or planet pinion, around the other, called the sun gear or sun wheel. The planet and sun gears mesh so that their pitch circle roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear.
Now we are going to find Pitch circle diameter for ring gear
d = zm
here based on the given inputs
d(r) = 115mm
pitch circle of sun gear
d(s) = 35mm
pitch circle dia of planet gear
d(p) = 40mm
Based on the above value all the gear are made and based on the center distance of gears carrier is designed and based on the below condition the following solutions are obtained.
Sun Gear
Planet Gear
Condition
Then based on the challenge i have made inputs and obtained outputs they are as follow
condition 1 :input = sun gear; output = Carrier ; fixed = Ring gear
For the above condition the plot is made
and motion study video is made and uploaded in youtube

condition 2 :input = Ring gear; output = Carrier ; fixed = Sun gear
For the above condition the plot is made
and motion study video is made and uploaded in youtube

condition 3 :input = Sun gear; output = Ring gear ; fixed = Carrier
For the above condition the plot is made
and motion study video is made and uploaded in youtube

Result:
Finally the have been designed and motion study on the gear have been done and their vedios are uploaded in the form of video in youtube and part models are uploaded via google drive.
