Ill check it out!
wait, you wanted to run chains on it?
I could work with this, though it would be nice to get some more info. ive been tinkering with it for a small bit.
that 6 hole bolt pattern I used has a bunch of belt and chain drive options from robotics suppliers, so that is why I wanted to use it.
Feel free to ask away.
also I modeled it for 22mm od bearings because thats what I had onhand but 28mm od would save a lot of print time.
The problems I saw with my current hub are that I didnāt want to put locating/interlocking features into the hub to make it as simple to print as possible. Then in order to make the super wide wheel fit on I offset it quite a bit like 20mm, that made the split hub wobble quite a bit under load. That also could be due to non press fit bearing clearances. I think precise bearing seats would be easier to print with 28mm od bearings.
So if Iām going to print a new one it would be a single part hub, with 28mm bearings. That I think could be ridable and not feel crappy.
Also the thing that should really be created here, hubs for the larger 12in wheeleez hasnāt been done yet. Those hubs would be a pretty significant print given the diameter. So for them maybe buying and adapting the stock hubs is extra advantageous.
A 12in wheel is possibly too large to use with a single cots gear drive reduction, needing a custom chain or belt setup.
I think the problem is that you put your bearing seats on two different parts yeah, that could lead to wobble.
see I modeled most of it in a single part, to check bearing bores and width easily without cleaning I then split the hub.
The pulley as well should bolt directly to the hub not using a spacer. Then if it uses 28mm od bearings I would feel safer using only two.
Thatās downright ridiculous.
I need some of those on a 30" shortboard. Front & back wheels would just about touch one another, eh?
if you used the 12in/30cm or larger ones yet just about. I am sure you could make some high steering angle board where they could touch at full lean.
to get that shortboard feel I think the TLT design is more ideal. Given the weight using 3 is quite desirable.
I forgot about lean. Yeah on a 15" wheelbase I bet you could 100% start getting some wheel-to-wheel-bite with 12" tires.
And probably fall off the board about 17 times before you figured out how to ride it.
Kneeboarding ftw
while I am throwing out non-skateboard like board designs that would possibly be a good fit for these wheels.
CURVA Board. Rocker and Edge Pneumatic wheeled unique board
bonus is like on the TLT board you could use a single motor setup. thats one less motor to service from salt exposure and one less esc at risk.
