this is a model of differential which as a mechanism is commonly used in motor vehicles. This example is not a copy of any real thing. Its purpose is only to show how such things works on a basic level. Videos how to assemble all parts and how to operate it are here:
Note: this black example is made from polished plastic and its parts are too lose (you may see this on video). Parts made from ex. versatile white plastic will be fit well (checked). If you want this thing made from polished plastic, please leave a request and I'll prepare such version but be patient - it'll take some time for redesign holes and shafts and few days for checking parts manually.
Number of teeth in gears:
Warning: number of teeth, planets and shapes of parts aren't calculated for working load and forces so this thing cannot be used in real applications.
- planets: 3x10
- side gears: 2x18
- ring: 21
- pinion: 7
Model contains small parts which can choke children or be swallowed by them.
