Planetary Gear Set - easy to print, easy to assemble.
This design is meant to show how a planetary gear set works. Focus for the design was to make it as simple as possible to print and to assemble. Resulting in a design which is printable without support structures, big overhangs etc. To assemble the gear set there is no glue, silicon spray or tooling needed.
Some facts (skip if you just want to print):
-Stationary gear ratio, i0 = 1.88 (1.9)
-Module: 2
-Ring gear teeth: 51
-Sun gear teeth: 27
-Planet teeth: 12
-Number of planets: 3
The gears do have a real involute gearing. For the planet gears it was necessary to add a profile shift of 0.3 x m to avoid undercutting. In order to design the gears, a parametric CAD-File in which you can set all the parameters for the gear was created. The involute gears will then be generated automatically.
Printing:
The model which you can see on the pictures was printed with PETG (red and black) and PLA (blue). As mentioned befor
