Greetings all;
It looks like I am going to have to dis this $600 piece of junk and take
it to the car wash to clean out the manufacturing debris.
Which brings up a need to re-lube it as I put it back together.
It has oil ports, push the teeny ball types, but it seems like it really
should be
Pity this guy claims he's lost the cad files. Seems a pretty good 3D printed
harmonic drive.

And I know solidworks can do that too.
I would definitely want to mathematically calculate it. Seems a waste to
introduce error on the first step lol. Especially if I don't have to.
Might be a good idea to 3d print the first one and then make a big proper
one from
Pretty sure I read an article about harmonic drives and cycloidal drive from
local university.

There are two good tutorials on designing the gears. Both depend more on
geometric construction than math. They first generate some points then
fit a spine. I've read this is not-exact but the error can be as small as
you like. Just make more points and the spline gets better.
Going into the
Look for drawn cup needle roller bearings. They're made in a wide range of
sizes.

So do they use some needle roller bearings that run on the lobes or
something?
I could make that work I reckon. I already have the
