This LEGO®-compatible planet gear carrier is a companion to my
40-teeth ring gear. It allows for many configurations of
epicyclic gearings:
- 8-teeth sun gear and 3x 16-teeth planet gears for a 1:6 ratio
- 16-teeth sun gear and 3x 12-teeth planet gears for a 2:7 ratio
- 24-teeth sun gear and 3x 8-teeth planet gears for a 3:8 ratio
Because of the 3D printing process, holes can be a little bit tight when you receive your print. Corners of the central hole in particular may require to be cleared with a utility knife or a file before an axle can be inserted. Rounded holes will eventually wear off but you can also help that by rotating an axle in them or using a file. The 3 cross holes for bearing 16-teeth planet gears are a bit lose. Sandwiching the gears with a
secondary planet carrier (that is, the one with a rounded central hole !) might help keeping the axles in place.
