Sheepo's Lego Technic Planetary Gearbox w/ Instructions

[DLuders]

As noted by Parda on the Technic Delicatessen, Sheepo made this interesting Lego Technic Planetary Gearbox. . He wrote, "For more information please visit: http://www.sheepo.es/ . You can donwload instructions for both types here:

http://www.megaupload.com/?d=9BJAOEB8 . Using the planetary gearbox idea I have designed a version without planetary gears ;). It only uses standard gears (as z12, z16, z16 with clutch, z20...) and some axles and liftarms." The YouTube video shows it in action.

"TYPE 1 -- 3 SPEEDS IN THE SAME DIRECTION

- 1st speed: locking the first rotor the gear ratio is x0.8

- 2nd speed: without lock rotors, direct transmission x1

- 3rd speed: locking second rotor -> x1.6

Of course you can ger others gear ratio changing some gears"

"TYPE 2 -- FORWARD, NEUTRAL, AND REVERSE

Looks almost like the 3-speed type, but is very different.

- Neutral, without locking rotors

- Reverse, locking the first rotor

- Forward locking the second rotor

You can join some of this types to built a big gearbox with more speeds, reverse and neutral. now some examples."
