Film: 1950s Army planetary gear demonstration model
Learning about planetary gears by trying to visualize how they work, and I came across this neat old training film. Seems I'm not alone in needing animation to understand!

I Love this stuff!!!
It amazes me how much advancements were made and discovered in the early 40's through the late 50's.:thumbup: I think planetary gears transmissions auto type transmission are just the perfect package. Compact and strong as Hell.:cool: |
I've never been a big fan of planetary gear sets. But it's possible that's because I associate them with automatic transmissions, which I strongly dislike...

Did you notice that explanation of the two-input planetary gearsets used in tanks? That's exactly how Toyota's groundbreaking Hybrid Synergy Drive works (specifically the "Power Split Device"). Toyota Prius - Power Split Device |
