Exploring a Planetary Gear Drive Pt 2

[hubzcaps]

look closely at the set at the very top middle is an audio phone for a modem of sorts heheheh acustic 300 baud pickup?

And by the way.. no - it's not a pump.

you should watch it till the end. he recognized it himself^^

It's called a cycloidal drive.

A common solution replacing regular planetary gears in applications demanding either a near backlash free drive and/or low maintenance.

It's used extensively in automation and robotics.

In this particular case it was most likely chosen for it's near zero backlash.

Shame you banged up the bearings, even a second hand high quality unit like that is worth a pretty chunk of cash. Now, thanks to improper handling - it's worthless.

Actually its called Hypocycloidal from what i´ve seen.

When a company donates expensive equipment to a not-for-profit like The Geek Group, they usually have a set of rules that go along with it. Most of the time that means they can't sell any sell it off, or sell any parts from it. The most they can use it for is to take it apart, and use its parts. It essentially legally became worthless the moment the company donated it to them.

could be a traction motor?

Excellent videos!. I love doing vidoes on taking things apart, and an industrial robot has to be the coolest one I have seen on youtube!

It looks like it uses resistance from the grease as well as the eccentric gears to create smooth low speed, high torque motion

Oh yeah, I'd give anything to dismantle something industrial that's as clean inside as that drive :D

IT'S SO WRONG
