You can actually get very similar behaviour using a standard differential. If you hold one "output" shaft, and turn the other, the crown wheel turns at half the input speed. The advantage of planetary gears is the output shaft is in line with the (...) (24 years ago, 4-Oct-00, to lugnet.technic)

Ah. Hm, I wonder if it could be used for a lego transmission. I cleaned up my first planetary gear, and I came up with a second implementation. It is bigger, and it is not obviously a planetary system, but I think it is topologically equivalent. It (...) (24 years ago, 4-Oct-00, to lugnet.technic)

That alternative implementation gives me an idea. What about putting gear wheels around on arms sticking out at various angles and held together by structural Technic parts, and having various combinations meshing with each other? The only problem (...) (24 years ago, 4-Oct-00, to lugnet.technic)

(...) Planetary gears are still being used as maintainance-free transmission systems for bycicles, build inside the back nave. They work very well, I own a bike that has 7 gears crammed inside a ±10 cm diameter hub. Greetings, M. Moolhuysen. (24 years ago, 4-Oct-00, to lugnet.technic)
