Robot Wheels
The wheels in BattleKits are four or five inches in diameter and 1.5 inches
wide. We also offer 5, 6, 8, 10 and 12.5-inch wheels. All our wheels have
built-in sprockets or aluminum hubs with keyways.
| |
|
|
|
|
 |
We broach a 1/4" keyway into
the wheel. A steel key locks the wheel and sprocket together
so the torque on the sprocket gets transferred to the rubber tire. |
|
 |
| |
Our custom one-piece hub/sprockets are made from
chrome-moly steel and finished with black oxide. Our kits use sprockets
with 19 teeth. We also offer wheels with 28 and 42-tooth sprockets. |
 |
One bronze and one ball bearing go into
each wheel. The bore diameter on all bearings is 1/2-inch. Our sprockets are made to be used with #35 roller chain (3/8"
pitch)
|
|
 |
| |
This
drawing shows all five components in the assembly. The width of the
4 and 5-inch wheels is 2.24 inches. All other wheels are 2.34 inches wide. |
| |
|
|
|
|
All our kits have the 4-19 wheels included. Our 5-28 wheels can also be used on the kits,
(with some modifications). The ground clearance on our kits can be increased with the 5-inch
wheels with a little extra machining. Contact us and we will give you a
quote for the custom machining or we can provide detailed drawing if you
choose to make the change. If you already have a BattleKit, we offer this
conversion kit to switch to 5-inch wheels
and increase ground clearance.
High-Traction Wheels with Sprockets
High-traction rubber and light weight make these wheels ideal for
robots. Use with 1/2-inch axles and #35 roller chain (3/8" pitch).

Hard Plastic Wheels with Sprockets
The hard plastic wheel reduces
traction but also makes turning easier and reduces power consumption
while turning. In the BattleKits robots, Two 4-19HP wheels can be used in combination with two regular
high-traction 4-19 wheels. This will give a good combination of traction
and ease of turning in robots that do not require uncompromised traction. Educational
and experimental robots along with robots intended to operate on carpet may work
best with two, (or even four), hard plastic wheels.

High-Traction Drive Wheels with 3/4-inch Keyed Hubs
These wheels have a 3/4-inch aluminum hub with a 1/4-inch keyway.
They come with two steel discs for holding the wheel in place on the end of
a 3/4-inch shaft. The 1/4-inch key is also included. Order these wheels
individually or combine them with the AmpFlow gearmotors - available on the
Wheelmotors page.
