Planetary gear box [1:3]
3D
Published 2019-07-12T08:20:16+00:00
Simple planetary gear box with 1:3 reduction rate.
There are two handles that allows to rotate the sun gear (little one) or the carrier (big one).
Feel free to comment if you find any issue or suggestion! It's very important for me because this is my first design!
You need also:
-2x common bearings (8x22x7mm)
-1x empty Bic's pen tubes [you need to cut it in three parts of 24mm each or less, for the 3 planet gears axis]
-glue
You have to paste:
1) short axis to the sun gear
2) the two pieces of the carrier handle
3) the carrier handle with the carrier.
4) the sun gear handle with the axis.
5) the two Planet gear circumferential stops with the internal gear

Had to rework the two-part handle to get it to fit into the carriage (it was too big/profile didn't match), but no issues otherwise. Didn't have a Bic pen handy, so I just made some 2.55mm tubes (24mm long) in Tinkercad and printed them longways.
