looking to upgrade from lawnmower wheels ...

Threaded View
So far my new robot uses lawnmower wheels. But because I'd like to turn my
concept into a kit sometime, I just don't feel like the lawnmower wheels cut
it. (no pun intended!) They are kinda wobbly - not terribly so but they
don't give me a feeling of driving a straight and narrow course. I'd like
something that is about 6" in diameter, 1/4" to 1/2" inside where the axles
goes. Maybe a hard caster wheel or even aluminum with rubber coating for
traction ? Also need to support about 30lbs max weight.

Does anyone have suggestions for subsitutes ? I am of course looking for
cost effective solutions, but I will gladly look into anything anyone
suggests!

Thanks again, as always.

cut it ...

Well, as is quite often the case I found some suitable wheels at
McMaster-Carr web site.

But most of these have bearing inside where the axle goes, and I'd like to
connect the motor straight to the wheel somehow - so the motor axle turns
the wheel. Anyone have experience "locking the bearings" ? Is that even a
viable option ?

I guess the other option is to attach a pulley to the wheel and drive it
with a belt.

Thanks for any help!

A little beefy for my application, but still a cool site to browse through!
I had no idea GoKart wheels were so small!
Does "live axle" mean one connected to a drive wheel ?

Thanks again !

Yes, I believe so.

Cool. This link goes in my notes, for sure. Seems like a great place to shop
at for outdoor robot parts!



Re: looking to upgrade from lawnmower wheels ...


These guys have a good collection of tires and wheels. They also have
motors, gearboxes and chain/sprockets: http://www.surpluscenter.com/

I have been dealing with them for a while and had good results.

Excellent! I like their presentation of caster wheels better than
McMaster-Carr --- easier to browse !
Thanks!

This company that used to go by the name "Northern Handyman", I've
been to one of their retail stores around Atlanta, they have lots of
different kinds of wheels and tires:

There's this old standby for cheap imported, er, uh, "value" items:

http://harborfreight.com/

but if you expect to design a kit to sell as a business, you need a
supplier that's going to still have the same product available a year
or more down the road, so you don't have to redesign your bot for new
wheels while you have 10 orders from people wanting kits. For that,
one of the big industrial supply houses is surely a better bet.

http://www.mcmaster.com/
http://www.grainger.com

You already mentioned Mcmaster Carr (and I thought they had
everything). For others, Google or Yahoo for industrial supply.

If you really get big, you can order directly from the Chinese
manufacturers/distributors of these things.

   I was thinking of the one in Duluth, but there's one on your side
of town in Marietta:

While I'm doing the surfing for you, Harbor Freight has a retail store
in Kennesaw:

Re: looking to upgrade from lawnmower wheels ...


Fair enough ! :-) I will do the surfing for you sometime.

I just visited that one a couple of weekends ago. Definitely a cool store to
window shop in.
